...for the moment, at least. 2005 CR-V AWD VTech, ~150k. About a week ago, I started getting the check engine light popping on, and the VSA/traction control lights lighting up 30-60 seconds thereafter. I had the codes scanned at the local parts store, and came up with the following:


62-1 ABS Battery Voltage High Malfunction

83-1 ECM/PCM Relation Failure

86-1 controller area network relation malfunction

P0011 Camshaft Positions sensor

etc, etc


But here's the thing: the vehicle is running just fine. There's no new lugging or hesitation I can sense; the lights just pop on and the car runs merrily along. A cursory sweep of 'Net resources suggests a communication error of some sort. A corroded plug somewhere? Any assistance is appreciated, thanks.

 

Check your battery voltage ( running at idle and at 3000 rpm). Possibility of a faulty voltage regulator in the alternator.
....first clue is the high voltage code; abnormal voltages high (or low) will trip codes as sensors will be sending higher voltages back to the PCM which in turn the PCM will read and report as high sensor voltage readings.

Check all the battery connections and check all the grounds to the block and frame from the battery as well.

 

That makes sense, thanks.
