THE CAM SHAFT ACTUATOR IS LOCATED IN THE CYLINDER HEAD ON THE FRONT RIGHT HAND SIDE JUST ABOVE THE POWER STEERING PUMP. AFTER YOU REMOVE THE ACTUATOR CHECK TO SEE IF ANY OF THE SCREENS ARE DAMAGED OR MISSING. IF SO REPLACE THE ACTUATOR. ALSO CHECK THE CRANKSHAFT END PLAY. IT SHOULD BE BETWEEN 0.0044" - 0.0153". if excessive crankshaft end play is causing this concern, it will be obviously out of specification by as much as.050" or more when a pry bar is used to move the crankshaft back and forth. IF THIS IS THE CASE AN ENGINE REPLACEMENT IS RECOMMENDED DUE TO THE AMOUNT OF DEBRIS IN THE ENGINE. IF NO EXCESSIVE CRANKSHAFT MOVEMENT NOTICED REPLACE THE CAM ACTUATOR. IT WILL ALSO BE NECESSARY TO DO AN OIL CHANGE.

You need to check the cam phazer and see if it's damaged. Lots of the time it leaks oil into the connector and messes up the wires. Also I've seen the oil control screens come out of the phazer and go into the engine, which will also set the coeds. If I were you I'd pull the phazer out and see if all 3 of the oil control screens are there. My bet is one will be missing. Make sure to change the oil too. You may get lucky and it will have made it to the oil pan? Other wise I wouldn't worry too much about it. Most of the time it will not cause any engine problems. Good luck, oh and you do have to pull the power steering pump off to get the phazer out. But you can just take the bolts out for the pump and let it fall down so you can get the phazer out!

DTC P0014 Exhaust Camshaft Position (CMP) System Performance.
The cam phasing system is a hydraulically actuated phase shifting mechanism. The powertrain control module (PCM) supplies the ignition positive driver and ground circuits. A pulse width modulated (PWM) driver controls the amount that the camshaft actuator solenoid assembly advances or retards the exhaust camshaft. The exhaust camshaft is commanded to a maximum ****** position of 25 degrees. When the exhaust camshaft is retarded at the maximum rate, the duty cycle of the signal is at 100 percent. The maximum advance rate has a 0 percent duty cycle. Other than when the camshaft is at full advance, a 50 percent duty cycle is used to maintain a steady ****** angle.
Remove Cam Phaser Solenoid and inspect it to ensure that all 3 screens are intact. Chances are you will need to replace this Solenoid and change the oil immediately.

Common problem on the 03-06 Trailblazer instrument clusters for the fuel gauge to go out. It's usually caused by one of two main problems, either the stepper motor on the cluster's circuit board is going out or the sending unit on the fuel pump is going out. Check out this blog post about the problem - Trailblazer fuel gauge problems
