Title: Crankshaft position sensor
Post by: bobmcc13 on October 22, 2019, 10:18
Here is an easy one.
Could someone please tell me the exact position of the crankshaft sensor on the engine.
Can I get to it from the top or do I have to resort to crawling underneath the car (again)
I know someone out there will help me.
Thanks in advance

It's an 'underneath job' I'm afraid.  It's at the bottom of the timing cover on the side closest to the bulkhead.  Very often a problem with this sensor is down to a corroded earth connection, which is just above the sensor on the timing cover.  If you take out the small retaining bolt for the earth and give the connector, the cover and the surrounds a thorough brush-up, more often than not, that does the trick.

I found it very awkward to physically get the tool to it.... get the car high up so you have 'elbow room'.

At least I will be poking round in the right place.
Thanks for the info.
Once again I am reminded why I am on the Forum, it's brilliant as are the contributors, there is nothing they don't know.

Thanks again.

Its a total pain in the ar$e location to work on.  Good luck.  I was so frustrated with it.  It was a dodgy earth on here that was causing me no end of trouble.

Thanks to Carolyn I found the sensor and what do yo know, the earth lead was all green and the wire was rotting through.
I bypassed the original earth and made the job good.
Guess what! My incessant 1349 fault has disappeared and all is well now.
I think the moral of this story is to look at the simple things first instead of jumping in at the deep end and replacing bits in the engine.
Once again thanks Carolyn
