On a 2008 Saturn Aura my check engine light keeps coming on
Asked by emeade Sep 10, 2013 at 05:11 PM about the 2008 Saturn Aura XR
Question type: Maintenance & Repair
On a 2008 Saturn Aura my check engine light keeps coming on, the error code is P0011 cam shaft sensor. It comes on when I driving home, but not on the way to work. And this happens at the same spot every time. It’s very intermitted and driving me crazy. The sensor was replaced a year and haft ago.

A code P0011 refers to the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car's PCM (powertrain control module, also called an ECM). That consists of a few different components but the P0011 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is above a set limit (over-advanced), the engine light will be illuminated and the code will be set. The "A" camshaft is either the intake, left, or front camshaft. Potential Symptoms Most likely a P0011 DTC will result in one of the following: hard starting, poor idle, and/or stalling. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates. Causes A P0011 DTC trouble code may be caused by one or more of the following: Incorrect camshaft timing Wiring problems (harness/wiring) in intake timing control valve control solenoid system Continuous oil flow to VCT piston chamber Failed timing valve control solenoid (stuck open) Going too long between oil changes
