I have a 2007 chevy impala Lt 3.5L flex fuel the problem stated a few weeks ago check engine lite came on reads code P0010 then it started shifting hard thru 1st and 2nd gear I have changed the camshaft positioning sensor and connector to it I'm thinking to change the camshaft positioning actuator magnet just looking for any other thoughts on this code? Also wondering if the hard shifting would be caused by something like this. Thanks in advance for any help and replies greatly appreciated![code]P0010
sounds like you're on the right track on your diag. and yes, this can affect you shifting. When your check engine light comes on the computer will change how it reacts to your driving the vehicle. basically it goes into a default limp mode. It will substitute a value for the cam sensor since it can't depend on the readings it sees. Some cars shift different, some turn off the cruise, some cars will turn off the AC for codes that may affect power or temp.
