Good morning all. My C3 picasso came to a juddering stop yesterday, the roadside assistants ran a diagnostic and it threw up a crankshaft sensor fault. I'm going to try and change it today but I'm stumped on where it is. Could someone tell me the location of it please.

The crank sensor is show in the red circle.

The TVD has been removed to show the sensor.

You may need to get the timing belt and the pulley off to change it

It may be worth just unplugging the sensor and cleaning the plug, socket and the senor itself with some contact cleaner before changing it.

Looks like a tough one to change. There's no way I'm touching the timing belt. I've been looking on other sites today and a few of them mentioned that it could be under the air filter or down by the oil filter. Thank you so much for your help. 👍

I only changed mine when I did the cam belt. Yes, it's not easy to get to.

I would try cleaning it as mentioned above because it can pick up a fair bit of debris down there.

If your VIN is correct then the engine identification is correct and the crank position sensor is shown in the picture above.

Good morning all. Big thank you to Arfur for pointing me in the right direction.
I managed to get at the crankshaft sensor this morning. I think I could have changed it without taking the timing belt off, there's only one bolt holding it on from what I could see. but as advised yesterday I was told to clean the connector to the sensor I went to do this and the plug just slid off in my hand, I cleaned it down, pushed it back on, heard it click into place and it fired it up. Thank you ever so much. 👍

Great work and thanks for the feedback.

It is normally a bit of a job to disconnect that (if not all) the plugs on the C3. It should have never been loose, so that is quite probably why the fault appeared and the engine stopped. Quite how it got loose you may never find out, but its fully home and tight now :)
