I have a 2015 Chevy Cruze LS with a 1.8L Engine clocked in at 74k miles. Ever since the purchase, the P0011 check engine light code is always appearing even after repairs done to attempt to fix the issue. The repairs were replacements of the timing belt, water pump, camshaft actuators and the camshaft phaser. I have noticed that the check engine light would turn off after a few days of not driving the vehicle but after driving on a highway for about 20 minutes and then turning back on when I stop at a red light / stop sign, the check engine light would turn back on. As of today, the car drives normal with no noticeable issues. EDIT: I also had 2 oil changes with full synthetic oil being used.

Bump. Could the code be related to a bad camshaft position sensor? Or an electrical issue?

Visit AutoGuysLand to review how long can i drive with a misfiring cylinder if you concern. As of today, the car drives normal with no noticeable issues.

It could be the wiring going from the solenoid to the ECM can become damaged or broken. Take a look at this.

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)

Possible Cruze P0011 Causes
There are quite a few different things that can cause the P0011. Here are the most common causes:

  • Engine Timing– If the camshaft(s) are no longer synced to the crank properly (such as if the timing chain jumped a tooth), it can cause the engine timing to be off enough to throw the P0011 even though it’s not the Actuator’s fault. Here’s more on that from this site: Timing Chain Jumped Symptoms and Diagnosis
  • Engine Oil– If the engine oil is dirty or low, it may cause the actuator to function improperly. Also, the oil viscosity can be off
  • Bad Intake Camshaft Position Actuator Solenoid– The actuator solenoid itself can go bad over time. You certainly don’t want to start here, since a lot of the time it’ll be something else that causes the P0011 to appear. Here’s a good video of someone replacing one, so you can see what goes into it.
  • Wiring Issues– The wiring going from the solenoid to the ECM can become damaged or broken. This will throw the P0011 OBDII code. The wiring harness to the intake camshaft position sensor may also develop a poor connection. YouTube: How to Find an Open or Short the Fast Easy Way.
  • Bad ECM (highly unlikely)- If the Cruze’s computer goes bad, then it may throw this code along with other issues. Here’s how to tell if you have a bad ECM Autoblog: Symptoms of a Bad ECM.
Here’s a phenomenal video on how to test a cam/crank actuator. It’s on the page instead of a link because it’s that worth watching. Always make sure that you check everything else that you can before actually opening up an engine.

Thanks guys, I failed emissions but got a waiver for all the repairs I've done. I'll let my mechanic look at my car again soon to get rid of that eye sore of an engine light. Car still runs fine and I'll reply if the issue is ever fixed.
