Question about 2003 Saturn VUE

1 Answer

My " service engine soon" light kicked on.

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?

    I had the tech check it and reset the code. I'm assuming there is further diagnostic work you are talking about that he can do?



    Closing in on 100,000 miles and just spending $425 on hub assembly and $400 on new set of tires, I am hopeful this is something that can be put off? I'm sure that is hard for you to say based on my limited info. Hey, thnks for your time man!! Any further input?

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.

    I would have it checked again. If there is a problem better to fix it now than have it critically fail later. The car cant run without that sensor.

Cen-Tech code P0113 intake air temperature sensor 1 circuit high.


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 !

How do I turn the service engine soon light off


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.

Service engine soon light blinking /car backfiring and missing


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.

Service engine soon light, service light, reduce power etc.


It is most likely the Throttle Position Sensor has gone bad. But if the check engine light is on, the only way to tell exact problem, is to have a scanner placed on the vehicle to have the codes read.

Service engine soon light on. failed aircare.showing code po341 .


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!

I have a 2004 gmc yukon when I try to start it it just cant kick over, the battery is fine it just cant get the final kick to start


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.
