Can anyone tell me what the classic early symptoms are of a failing cam sensor on a 2.2i petrol?

Thanx in advance!

Bad starting when warm (engine that is ) and possible rev limiting to about 4500rpm

Hmm...okay.  I'll tell you my problem.  I have noticed recently that sometimes when accelerating quite quickly to 60 or 70mph, the car sometimes feels as though it is holding back slightly through the revs, and then the power comes back (like a 'surging' sensation).

I also had a strange experience when coming back from Skeg one night recently on the A158, driving at approx 55mph, the engine 'lost' all power for approx. 2 seconds, and then came back (with a slight jolt).  Expected EML to light but nothing.  Never happened since.....

Possible failing crankshaft sensor.......but as you know it really needs to be code read first before thrwing lots of money at guess work.
Any Auto electrican should be able to read the codes, or someone on here may have an aftermarket code reader that may do the trick.

Before condemning anything - you need to read your fault codes...

I am planning to have a run down to Nottingham to see Marks DTM for an autobox upgrade in the near future, perhaps he could have a look with his TECH2.  I hear that he is a top bloke!!

That he is mate, that he is

That's your best bet, get it Tech'd by Mark.

Camshaft sensor usually brings on the spanner light and/or EML light, after not starting first time when warm/hot.

I'll second that too!

My camshaft sensor failed but if it wasn't for the EML i wouldn't have noticed!  I understand that the CSS generates a 'hall effect' which it read by the ECU.  Without this the ECU doesn't know what position the cams are in and in your case it might jump into limp mode...

CCS on a 2.0/2.2 isn't difficult, it can be done within the hour.

Correct AA....doesnt sound the prob to me...

BTW have you had cam sensor prob  :-/

Mine went with the exactly same problem. Had the codes read by local VX and found it was a EGR problem. Have blanked off this with a home made plate, but made too good a job of it. Had to drill a small hole underneath the piston side of the plate. Car responds as it should.

Get the code read and see if it is your cam sensor or some other problem.

i replaced the cam sensor on mine, problems where:

bad starting when warm, would take lots of cranking. Spanner light would come on.

started it up once, pressed the gas pedal, nothing happened, no revs... no nothing.

Both problems have not come back since the new sensor

would a crank sensor really cause that mis fire feeeling when travelling ( for my own info... :-/)

That's what we're saying, doesn't sound like the cam or crank sensors.
