P0011 : Camshaft Position Actuator A - Bank 1 Timing Over Advan.
P0456 : EVAP Emission Control System Leak Very Small

63k miles, 2002, AT

This scares me a little. I just changed O2 sensor and MAF two weeks ago. What's wrong with my car?

 

Yikes~!

I don't like the sound of that first one, since it's related to your Intake Valve Timing control.

You should see if that crank sensor TSB applies to your VIN.

 

FSM possible cause:
- Harness or connectors
(Intake valve timing control solenoid
valve circuit is open or shorted.)
- Intake valve timing control solenoid
valve
- Crankshaft position sensor (POS)
- Camshaft position sensor (PHASE)
- Accumulation of debris to the signal

 

DTC Detecting Condition:
There is a gap between angle of target and
phase-control angle degree.

Fail-Safe Mode:
When malfunction A or B is detected, the ECM enters fail-safe mode and the MIL lights up.

Intake valve timing control The signal is not energized to the solenoid valve and the valve control does not function.
