My C180 1998 elegance does not fire very well at low speed. After scanning, it was detected that the cam shaft sensor is bad and I have replaced it twice and yet no changes on the performance. How do I get a brand new sensor or do you think that the fault is coming from somewhere else? PLEASE ADVISE.

Have you had it scanned once more upon having replaced the faulty item on two occasions? Perhaps you should have your IAC valve diagnose too, as it causes a trifle of idling complications.

Scanned it after the replacement was done and still having the same fault.

What kind of scanner did you use, OBD II or star scanner?

A camshaft fault that keeps coming back after a cam sensor has been replaced with a good one and the harness intact, to me, means the timing belt or whatever that is driving that camshaft, is about to break, snap, slip off, etc. It's simply telling you the camshaft is out of position or the sensor is no longer detecting camshaft position, due to jump of tooth or whatever.

If i were you, if i was sure the replaced sensor is new enough to be good and the sensor harness continuity to the ECU is intact, i would have opened up the timing chamber by now. A day delay could cost you a month regret, if that belt or whatever breaks on you.

used obd2 scanner

Well, you gotta check stuffs around, a clog of dirt could possibly make this happen. How is the part surface of shaft that serves as a sensor actuating point like? Dirty or what? Worn??

Thanks Ikenna, I will ask the mechanic to check the timing chamber.

Has your mechanic checked for possible cuts or breakage in the sensor wire?

*Most people don't know the difference btw OBD II scanner. brands and are oblivious of their varying capabilities*
-Did ur mechanic use a professional scan tool or the DIY scanner the size of a calculator or POS machine?

PLEASE ADVISE.

1. Don't go resetting your timing belt yet until you confirm that the subject sensor communicates well with your ECM.
2. If your mech is using a DIY scanner (that might not have been updated for years) pls find a tech with a Professional scan tool like the "STAR scanner" "AUTOBOSS" or a "LAUNCH X-431iv"
