Hello

Please help..

Just got myself a fiat punto grande 2006 sporting 1.4 16v and I changed the oil with Asda 10w40 (emptied fully, changed the oil filter and filled up).

My engine light is on and sometimes the battery light comes on whilst I am driving.

Whilst driving, when I stopped at a junction the car turned off by itself!

Whilst idle and just started the car it turned itself off too.

I read the code as P0011 and have since tried cleaning the sensor as I accidentally got loads of grease on it when I sprayed WD40 on the alternator belt as it got stuck and it must have sprayed onto the sensor.

This has not helped.

I have read forums that say that even though I used the wrong oil it shouldn't cause major issues - or any noticeable issues.

Does everybody agree on this because I was going to change the oil again to 5w40 but if its not a big deal and will survive til it needs topping up with the correct oil I will leave it.. can I top it up with the 5w40 whilst it has a bit of 10w40 inside?

Any other ideas as to how to fix P0011?

Thanks

Although it doesnt sound like your actions would have caused this, I have read the cam shaft sensors can get fooled if muck builds up on the tip. Its worth a try to remove it (simple to do) and give it a good clean off and pop back in. No harm in trying and at no cost

Thanks PJ - you have affirmed my next plan as I just sprayed wd40 degreaser on it and gave it a wipe, was going to do it properly and replace the sensor - but I will do what you said first, take it off, clean and put back on.

No problem, let me know how that goes. Normally just one screw or bolt that holds it in and the electrical plug to remove.
