CHEVY CODE P0014

2005 Chevrolet Trailblazer

Engine Mechanical problem
2005 Chevy Trailblazer 6 cyl Two Wheel Drive Automatic 66300 miles

My trailblazer is throwing the P0014 code. When they pulled it up this is what it came up with : the ecm has detected the camshaft phase angle has exceeded its tolerance value. Can you please tell me what that means and how can I fix that.

You have to remove and inspect the 3 screens on the cam phaser actuator sensor, they break off and fall inside the engine. There is a bulletin for this, 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. 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 as shown below: 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. Don't worry to much about the crankshaft end play to much, it's a rare occation that this happens, follow this info. Post back with what you find.
