A tech checked it for me and said a bad cam sensor was the code. He reset it and of course it has gone off again. I recently had the right front wheel hub assembly replaced which i'm sure is unrelated. The car drives well. Any ideas? Shoulld i get this fixed or can I just keep driving it? Can you tell me what this cam sensor is indicative of?

Re: My " service engine soon" light kicked on.
The cam sensor is a magnetic ring that senses what position of 360* it is at. It is responsible for telling the computer when and which fuel injector to fire. Being that the care is running fine this indicates that there is an intermittent fault at work. I would have it checked by a tech as I am one. I would also tell the tech that it is an intermittent problem, basically he will figure it out if you describe it the way you told me. It is going to come down to an engine diag. The price veries from shop to shop about 150 to 200, this price does not include parts or labor.

what kind of light,check engine, abs,traction control? usually if the check engine light or service engine soon light comes on under heavy acceleration it leads to a bad O2 sensor. check the ECM for history codes.
Check intake air boot or duct for a small 2 wire sensor, you may have not seen it as u pulled duct out of your way, don't feel bad I've done it before check that first , if u can't find one that it will be a internal part of the m,a,f, mass air flow sensor , usually a big round sensor inline of intake duct both of these will be before the throttle body ,mag has 4-6 wire connector !
you have to unhook the battery for about 20-30 minutes, and this will reset your check engine light. If it comes back, you have a problem that needs attention; it may be a sensor gone bad, or something along those lines, but you will have to have the code scanned to find out what's up with it in order to fix the actual problem.
If your check engine light is blinking, you can take your car to Autozone, Advanced Auto or other parts house and ask them to get the engine codes. This ios a FREE service. It sounds like your camshaft positioning sensor, Cam Positioning sensor is bad. This is how comuterized systems tell where the cam and crackshaft are to set the timing. It sounds like you have timing issues.
most any sensor going bad can cause the check engine light to come on,try disconnecting the posative battery cable for 15 seconds ,then put it back on,will reset the codes, or take it to auto zone,they will test your computer for codes at no charge to you.i had a venture van my was ox. sensor. thanks robert b.
IF YOU HAVE AN AUTO ZONE OR ADVANCE AUTO PARTS WERE YOU LIVE STOP IN TELL THEM THAT THE LIGHT IS ON THE CAN RUN THE CODES AND TELL YOU WHAT CODE ARE BEING SENT SOMETIMES THEY ARE NOT MUCH HELP ON WHAT THE CODE MEANS AND IF THAT'S THE CASE WRIGHT DOWN WHAT THEY TELL YOU AND LET US KNOW YOU SAY THE LIGHT IS ON BUT CAR RUNS FINE MOST OF THE TIME ITS THE O2 SENSOR GOING BAD /GONE BAD IF THE SAY ITS THE O2 SENSOR ASK THEM TO RESET THE ECM A.K.A COMPUTER IT MAY HAVE JUST BEN A GLICH IF IT HAPPEN ANY MORE PLACE THE SENSORS
The service engine light DOES NOT mean change your oil. The change oil or maintence required light means change oil. The service engine light is the same as a check engine light and means that there is something (not always really bad) is going on with your motor and need someone that has a code reader to let you know what the code is. Yes that code is a camshaft position sensor code. It is located on the passenger side of the engine in the "valley" between the two cyclinder heads. Its not too hard as long as you have some tools and some skills. Its easiest to remove the serpentine belt and remove the bolts for the power steering pump. That way you can move the pump a little to gain better access to remove the cam sensor. Just replaced one yesterday on a 99 century. Hope that helps!
Check the "knock sensors" under the intake manifold, notorious for water damage. Need to check the fuel pressure as well. Fuel pump could be bad. Has the "Service Engine Soon" been on at all? It's all a "**** shoot" without the proper testing equipment.
