bad camshaft position sensor

Featured Replies

Get the codes from the ECU. Is the CEL on? It could be anything!

  • Author

I've got all my codes and such. I know that a bad camshaft sensor will make the car hard to start (when it's warm and such.)

 

As I understand this sensor tells the ECU when cylinder 1 nears TDC and in effect tells the injector when to inject gas. Hence the result of not starting easily when bad.

 

So, could this sensor (when bad) miss the timing of TDC and cause the engine to stall because of inproper fuel mixture?

The IAC, or idle air control valve would be my first starting point, they rarely go bad, but they do get dirty with age and don't like to slide easily causing a searching idle and sometimes stalling at idle. I'd check that out first, unless you have cam or crank sensor codes.
