2002 chevrolet trailblazer diagnostic code p0013, p0014


Two possibilities, poor electrical connection at the cam position actuator sensor (CPAS) connector or a clogged CPAS. Check connector first for oil residue. The CPAS itself is prone to clog if the oil is not changed at the proper intervals. Unfortunately, the CPAS is a little difficult to remove since access to one of its bolts requires the removal of the power steering pump.

My autoScanner is showing a code of P0014, protenting to timing and cam poistion. I have a 2002 Trailblazer.


DTC P0014
Circuit Description
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.

If the desired and actual cam phase angle error exceeds its tolerance value for a certain amount of time, then DTC P0014 will set.
Condition/Concern:
On rare occasions, a rough idle may be encountered with a P0014 and/or P0017 DTC. Due to the rough idle, a P0106 DTC may be stored too. This concern may be due to debris in the camshaft actuator system, which may be caused by a missing camshaft actuator solenoid screen or a worn crankshaft thrust bearing. Typically, this is the result of a camshaft actuator solenoid concern. If this is due to a worn crankshaft thrust bearing, some customers may also comment on a drive belt noise.

Recommendation/Instructions:
If this concern is encountered, follow the SI diagnostics and repair as necessary. If the SI diagnostics do not isolate the cause of this concern, ensure that camshaft actuator solenoid screens 1, 2, and 3 are in place.

(1) Screen for Advance Pressure to Camshaft Actuator
(2) Screen for Pressurized Oil from Oil Pump
(3) Screen for ****** Pressure to Camshaft Actuator

If any of these screens are missing, replace the camshaft actuator solenoid, change the engine oil and filter, and evaluate the concern.

If all these screens are present, measure the crankshaft end play to determine if it is within the specification of 0.0044" - 0.0153" (0.112 - 0.388 mm). Typically, if excessive crankshaft end play is causing this concern, it will be obviously out of specification by .050" or more. If crankshaft end play is within specification, replace the camshaft actuator solenoid.

If the crankshaft end play is obviously out of specification, inspect the engine block for damage due to contact with the crankshaft.

If there is no engine block damage present, disassemble the engine and inspect the following components for damage due to thrust bearing debris in the engine oil: all bearings, all journals, all valvetrain components, all timing components, and the crankshaft

P0014 code and the cruise will not work


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.
