Title: Eeek! Saw the Engine Management light!!
Post by: ad_car_08 on August 24, 2009, 11:32
Driving to work this morning, following some doddery old folk doing 20 in a 30 zone....my engine management light illuminates..EEEEEEK!!

My car is completely standard (bar the mk iii pipe which was fitted last Oct time) NON import and I've never had a problem with it before, so far as the engine management light illuminating anyway, so I'm hoping it's just the MAF sensor telling me its feeling a little grubby. I've not cleaned it for a few months.

I'm due to take a 240 mile round trip to pick my girlfriend up from Luton airport tomorrow night, so I'm on a mission to get this fixed tonight after work otherwise it's curtains for me!

I know it's hard to say over the internet without seeing my car or without reading the error code, but if cleaning the MAF sensor (and removing the battery terminal for 15mins) doesn't turn the engine management light off, what else can I look at to eliminate the problem?
I'll have a look now at who is the nearest contact with a code reader, but I'm pretty sure there's no one close  s:( :( s:(


Any pearls of wisdom?....please?!

(I'm from Telford, Shropshire by the way!)

It will clear the light, wether it comes back or not, no one can say.

And Sean (slacey) lives in Telford

Brilliant, thanks.

A £25 code reader of Ebay is something that everybody should think about having in their car / garage. That is if you are the sort of person that wants to come on here and discuss it - rather than one who immediately goes to MrT and forks out ~ £50 to be told by them!

MrT  read my code when I first got the car and had a panic, no charge, great service so maybe get them to have a look first.

Just looked on ebay -  m http://cgi.ebay.co.uk/UNIVERSAL-OBDII-F ... 286.c0.m14 (http://cgi.ebay.co.uk/UNIVERSAL-OBDII-FAULT-TROUBLE-CODE-READER-OBD-2-SCANNER_W0QQitemZ300340499143QQcmdZViewItemQQptZUK_Diagnostic_Tools_Equipment?hash=item45edb052c7&_trksid=p3286.c0.m14) m
 Will that do the job? Are all/most manufacturers ports the same? I.e. Can you use fault code readers for VW, Ford, Audi, Toyota... or do you have to buy a specific one for each?

Thanks for your help

Dont guess then. A nearby member will read your clode and can clear it for you, possibly tell you the last few errors as well.

Then you can buy them a pint or an orange juice and make friends   s:) :) s:)

*Update* After cleaning the MAF sensor and leaving the battery terminal off for half hour while oggling the Hollyoaks tasties, the engine management light has now remained off.

I must've just got a little lapse on my MAF cleaning!

Just looking on ebay so i can get myself a code reader.
Seems abit strange that it was 24hrs after filling up on petrol...again...and I was following some excruciatingly slow driver...again

My friends Leon Fr needs to be goosed every now and again to clear it through, otherwise he gets a little light on the dash....couldnt be anything similar could it, or am I clutching at straws?

Sorry, checked mine and it was U380. Looking at specs on Ebay, you get a few more things with the (newer) U480, and a CAN standard, whatever that may be.

In my efforts to find a reader for JDM spec cars i bought one of these;
 m http://cgi.ebay.co.uk/Car-diagnostic-Sc ... 286.c0.m14 (http://cgi.ebay.co.uk/Car-diagnostic-Scan-Fault-Code-Reader-EOBD-OBD2-CANBUS_W0QQitemZ300346260431QQcmdZViewItemQQptZUK_Diagnostic_Tools_Equipment?hash=item45ee083bcf&_trksid=p3286.c0.m14) m

Now it is more expensive than many of the little code readers, but it is very quick, needs no batteries and does live readouts of data. You can also build a customised view and graugh any of the sensors / feeds from the ecu.

Delivery was 3 or 4 days and VERY well packaged... i like it   s:D :D s:D  

But it doesn't read the Jap spec cars   s:( :( s:(

I noticed that when I got home and had a poke around, the engine bay was a lot hotter than usual. The temp gauge was still reading halfway in the cockpit though?! The code reader should (fingers crossed) be arriving tomorrow to hopefully give me some answers!

OK, just a quick update - the code reader still hasn't arrived unfortunately, but....

...light has been on since Wednesday...
...drove to work this morning, light was on...
...drove to the local town to get lunch, light was on...
...drove home, light was on..
...drove  to my parents house, light suddenly wasn't on anymore?!

How come that's happened?! I didn't do anything?!   s:o :o s:o  

Does that mean that if the code reader comes tomorrow, there wont be an error code to read now the engine management light has gone out??
Title: Re: Eeek! Saw the Engine Management light!!
Post by: muffdan on September 25, 2009, 21:34
the code could be pending, in which case you will be able to read it. I bet it'll come back at some point though anyway.

I really can't find an o2 sensor replacement, for love nor money! Universal ones are 10 a penny, but i've read that unless you start fiddling with resistors etc it can throw up an engine management light because of the wrong voltage.

It's really hard to find a reliable supply of sensors that are more competitively priced than MrT. When someone stumbles over a good supplier i think they'll be inundated with orders.

I had to order mine from the states in the end. Cost £60 for a denso one. However i got stung on the import duty when it got here it was another £10-£20 on top. It was still cheaper than any from over here.

Make sure you that the import duty into account. Also they do a few different types, dont go for a cheapo one, it wont do you any favours. You can get them with and without the plug at the end (or you have to splice the wires together from your old plug.

Have you got a sensor socket?

Post by: Puerco on October 13, 2009, 12:19
I had a similar engine management light problem on my 2001 Jap model. It was a faulty O2 sensor - the secondary one, which doesn't cause the ecu to make any adjustments.  My garage, hoping to save me some pennies, ordered after market Bosch sensors, 3 in all, none of which worked.

While awaiting the correct part from Toyota, I did an 800 mile round trip, without any problem (apart from a yellow light on the dash)
The Toyota part, now fitted and light out, cost £85 plus VAT - little more than the aftermarket ones.  So, on this occasion, Mr T was the best bet.

If the primary sensor fails, it does totally confuse the ecu.  It also costs £180 plus VAT.
Title: Re: Eeek! Saw the Engine Management light!!
Post by: ad_car_08 on October 13, 2009, 15:43
So the local Mr T really is the place to go for one of these then

I bought a post cat O2 sensor from  m http://onlineautomotive.co.uk (http://onlineautomotive.co.uk) m  Pricier than the universal ones but I think slightly cheaper than MR T. Plug n play worked fine.

You might be able to get one from CTP (cheap toyota parts) for around £130 i think last time i checked. The states is the way to go mate
Title: Re: Eeek! Saw the Engine Management light!!
Post by: ad_car_08 on October 15, 2009, 16:28
Even at £130, that seems flammin' ridiculous for the part I need....  s:shock: :shock: s:shock:  

I presume that as i'm seeing the P0141 code (bank 1 sensor 2), that I'm looking at replacing one of the O2 sensors that I can see sticking out of the exhaust manifold when I look into my engine bay? (anyone know which on's sensor 1 and which one's sensor 2?) £160+ for one of those blighters seems a tad extreme!!

Thanks for the advice nathan, american it is!
Title: Re: Eeek! Saw the Engine Management light!!
Post by: Wabbitkilla on October 15, 2009, 16:37
Noooo!

P0141 refers to the heater circuit of the post-cat O2 sensor.
Thats the one you can't see looking in the engine bay, it's underneath after the catalytic converter.
A common fault and the sensor has a longer lead than the other two so is a different part number.

Hi,

Sorry, not a clue, I've had 2 down stream sensors from them no problem...also had one for my Honda 2.0ltre ultimately didn't work, gave me my money back without hassle. (Everyone and I mean everyone, has to get it from Honda at £171 ) ouch!!

I'm actually testing a reach cheap Yank sensor bought on Ebay as I write..the guy said it would do the job..... it hasn't completed the second cycle and if I'm honest, I'm expecting a cel......if no light in a couple of days  I'll confirm address.

If you're in a hurry would call the Essex mob mentioned previously.

Hi,

Felt I should update,fitted the universal upstream sensor last Thursday....as of Saturday 5pm car has travelled about 50 miles, some back roads at average speeds, stop /start maybe 12 times over the period, took it on By pass this afternoon....20 miles at 70plus....I was fully expecting a Cel........none as of this afternoon and none pending on the analyzer.

On the strength of what I've experienced so far, it could still go wrong but I have ordered another.

£24.88  total including shipping from US. (no duty)

It is billed on Ebay as 02 Oxygen Sensor 130HM 4W SG471 Toyota Corolla 02-95, although I have confirmed that it was for 2001 Mr2 Mk3 Spyder as my previous order.  
Item 350168637474
Customer Service Email  e evalero@hotmal.com e

With my luck it will hit me with a Cel on Sunday, alternatively, is it too much to ask that I could have stumbled on a cheap source of universal sensors for the 2 that actually work .....here's hoping!!

A few have used this one and left comments on the generic o2 sensor post which is probably the best place for this. I have also messaged them about length of wire and they replied "approx 70cm" so should be fine for the post cat sensor.

Previously ordered a universal 02 Sensor from Topsolutions at £29.99, came up with 2 codes in about  10 miles. I swapped it with the other upstream sensor position, same story more or less confirming a sensor issue.

Have just completed mail requesting return for replacement or refund.

Can you keep me informed as a good, working, no problem OEM type Sensor at £39.99 is a deal.

Cool, thanks B. I might just jack the car up at the weekend and have a look underneath to see if I can fix it (if the wires have melted or something) before I go dipping my hand in my pocket.

Post by: Wabbitkilla on October 22, 2009, 11:45
Melted ... unlikely, like i said it's a common fault.

The plug for that sensor is attached at the back of the coolant expansion bottle behind the nearside tail light.

Post by: Wabbitkilla on October 22, 2009, 12:49
Be aware that the cable is clipped in two places as it makes its way down to the senso.
imho it's the most likely sensor to fail as it's more open to the elements than the other two.  s:wink: :wink: s:wink:

Quote from: "ad_car_08"Im just having a look here for a new o2 sensor. If it's the O2 sensor on the bottom that I need, is it before or after the catalytic converter?

The MR2 Roadster has a PRE CAT, which you can see the heat shield for when you open the engine bay, unless uve had them taken out. It also has a normal CAT which most modern cars have these days.

The normal cat sensor is fitted low down and is classed as Post Cat or After CAT. The Pre Cat is classed as the Before Cat

This one is the one i would go for-

Take a look at my post in the group buys and let me know what you think.

If your unsure of anything still feel feel to ask. Your car wont be performing as it should if theres a fault. But its upto you.

The 3 sensors are basically the same, the downstream..post cat one has a longer lead that's all.

Hi,

Just wanted to double check something...

I received my replacement DENSO post cat o2 sensor this afternoon. Cracked it open and remembered someone on here (evidently you!   s:) :) s:)   saying it should have a longer lead - the one I've just received looks like it has about 20-25cm of lead. Is that right?

no! The post cat one should be much longer than that.

GAH!!   s:evil: :evil: s:evil:  
Just out of curiosity, how long should the lead be? Just so I can tell the company that sent me this one!

Thanks Dan

I can't remember, been many years since I had that sensor fitted to my car! I'm sure someone will be able to say, but I'd guess around 50cm

sounds like it, you could take the lead off your existing one and use that. Sort of defeats the purpose of buying a plug and play one though  s:( :( s:(

Are the plugs the same then? There are so many different pictures that say "not actual picture", I dont actually know what its meant to look like!

If it's the same, i might just splice the wires...
Title: Re: Eeek! Saw the Engine Management light!!
Post by: muffdan on December 9, 2009, 19:11
I believe so, but you can easily check! I was suggesting that you cut a length of wire (with plug) off your old sensor, and use it to extend the new sensor's lead. Then it doesn't matter if the new plug is the same or different.

Hi,

If you purchased a plug and play for the Roadster all the "plugs" are the same.
They would actually be universal the only difference being is that the post cat one which requires a longer lead as it connects at the rear of the nearside rear light and runs down to the cat.

A new post cat sensor would replace and would fit any of the manifold sensor holes, although you would have to tidy up the longer lead  with cable tie or whatever..

Hi guys,

Just had the same problem - bought the car on 16/12, everything fine, then yesterday on my way to Hayling Island the Engine Management light came on!

I cleaned the MAF and disconnected the battery; light went off.  Just took it for a spin and 10minz into the drive the light came back on.

I've just bought the U380 scanner off Ebay, but as the car is under a 3 month Premier Warrenty provided by the seller I'm just gonna take it to MrT in Worthing tomorrow and let them diagnose and fix whatever is wrong with it - hopefully it won't be more than 500squid as that's the max the warrenty will go up to in one hit  s:? :? s:? !

This site is gold - I wonder how I didn't notice it before  s:shock: :shock: s:shock: ?  Thanks for all the advice you guys have given out - it's really appreciated!
