Just had light come on and code read as P0014. Definition of this is a cam phasing error. Explanation is "The ECM has detected the camshaft phase angle has exceeded its tolerance value". I have my list of probable causes but wanted to know if these are popping up for Chevy's and if so what is the usual problem? Is it a sensor or something else mechanical? I have had no problems with the engine, everything sounds and runs fine, can I still saefly drive it? Just had mechanic look it over a week ago and give it the thumbs up on everything is fine. remove the cam phaser solenoid valve and check the screens for a restriction. This code usually comes up on vehicles that don't get regular oil changes
