Exhaust Camshaft Sensor Code P0014
first off i have a 2009 colbalt LT 2.2l nothing fancy, completely stock 72k miles. yesterday i was driving home cruising on the highway and my check engine light popped on, prompting me to pull over and check things out visually. nothing sounded out of the norm and everything seemed to be good. i get it home and take it to the local O'reillys and use their scan tool to pull the codes. what i got was this
Exhaust Camshaft Position (CMP) System Performance
does this mean the sensor has gone bad? the car seemed to be running smooth for the remainder of my drive home, decent gas mileage and whatnot. is there a way to test this thing with say my multimeter? ive got roughly 1500 miles left till my warentee expires so if it needs to be fixed i'd like to do it so as i drive that many miles in just a matter of a few weeks.
