as mentioned in your other smt related threads there have been mention of at least 2 good sources of smt youtube videos.

From your codes alone seems a communication error. is the info being sent? is it being received?
Matter of logical fault diagnosis.

The inevitable has arrived

Car started playing up one day, after mechanic had checked and topped up the fluid.

Not sure what exactly was done or what caused it, but since the fluid was played with, the car never changed the same.

Drove the car for a few hours thinking nothing of it, eventually ended up close to home and the car was having issues going into each gear, missing some, getting stuck in some, and other general transmission related issues (clunks, flashing gear indicator, non starts, etc)

Now at the point of needing an expert to check it out and see if it can be fixed.

I think the car is now not starting, and mechanic has taken a look but hit a brick wall.


Car is located North West of London


Is there anyone with the expert knowledge around this way that can check it out. Not expecting a fix for free, happy to pay for your time and towards any solutions to the issue/s.

With a basic code reader, the following codes popped up on the first day of problems. It may or may not have more/less codes by now after it's been played with by the mechanic.

P1646 transmission control ecu malfunction
P1647 CAN communication malfunction
ECMECT (engine and ect)

Hoping someone can help this car, rather than it going off to a scrapper !!!

That made me smile.

I would like to try one, already expressed an interest via IM.

Couple extra pics from the grass autotest too. Write up here: https://www.facebook.com/100063456275903/posts/pfbid02kekrU4fhL4eg9aVq4fL5d8s8vybHL47DRyzYjsguStem2Ri2CqZ5LCFrsUb4BQdBl/

Fast and furious style 🤣





Really need to paint the bumper 😅

Chilli my facelift 2002 had a supposed leak mentioned once or twice on its vehicle check. I never noticed anything in 9 years of ownership and to my knowledge is still the same!

A friend of mine who races an MX5 in a sprint series had some issues with his engine, so he was going to take his rally Micra to Gurston Down this weekend instead, settle for last, and at least pick up a couple of points. I wasn't having that. A deal was done, a swap was made...



I got a Micra for a weekend! I felt like a teenager again, it was a lot of fun. I even took it to a wedding, and found a friend:



What are the chances 🤣

Anyway, while I was struggling to get up to motorway speeds, wrestling the vagueness around country lanes, and bump starting the car, my friend was picking up points...



He was up against a Caterham and F Type so was aiming for third place, and that's just what he managed. I believe he was the fastest MR2, too... 👀



It's come back with a couple of battle scars/badges of honour, and a missing rear bumper infill, so will get it patched up and ready for the next event which I think will be Formula G at the end of the month. My new silencer hasn't arrived yet, so hopefully I can get that on too...

Once up to temp, the 3 o'clock position, it remains rock solid. Fans can come on, but the needle does not move.
@SurreyMR2
Plugging in an obd dongle will reveal the true temps. They do move up and down. Just not the needle.

A leaking water pump was mentioned in the Mr T service notes that came with my 2002 2 when I bought it in 2011.
It was also mentioned, again by Mr T when I had a first service with them. No mention of it in either two or three subsequent and I couldn't find any trace of a leak when I took over the servicing myself.

My daily Ford is North of 100k and when I had the cam belt changed the Ford recommendation was to have the water pump changed.
The Service Manager , son of the Main Dealer owner. didn't agree , saying he had never had to replace a water pump on that engine type. Coming up to a second cam belt changed, might have it given a good looking at this time.

I rather like the @SurreyMR2 suggestion of replacing the radiator cap. That was  not uncommon to hear of in the 60's .
