Cam solenoid is missing screen at X position
© DenLorsTools.com Summary: Many Chevrolet Colorado and GMC Canyon pick ups are having problems with P0014 and/or P0017 codes. This has to do with the correlation of the camshaft and crankshaft as the computer sees them. Idle can be affected and the vehicle can even stall. The culprit is almost always the camshaft actuator solenoid valve, not the crankshaft position sensor or a cam position sensor. There have been reports of rough idle and fluctuation as well. The solenoid affects the variable cam timing control. One of the tiny screens can wear and be disintegrated causing everything to go awry.
The good news is that this is an easy job to tackle. The camshaft actuator solenoid valve is located on the right side of the engine below the valve cover. It is held in with one 10mm bolt. Once the bolt is out, twist the solenoid while pulling it at the same time to remove. It’s easy to check to see if the screen is missing before purchasing a new one.

After replacing the cam solenoid and clearing the code, change the engine oil to help insure any remnants of the screen will be removed from the engine. Here’s hoping it does no further damage.
