ibroad Posted January 20, 2013 Share Posted January 20, 2013 My CEL came on last week, so I stopped by Advanced Auto today and got the codes read. It came back with the codes: P0065 Air assist injector solenoid valve malfunction P0137 Rear Oxygen Sensor Circuit Low Voltage P0138 Rear Oxygen Sensor High Voltage Has anyone dealt with these issues before? Does it make since that these codes would occur with each other? Where in the heck is the "Air assist injector solenoid valve?" Any help is greatly appreciated!

Fairtax4me Posted January 20, 2013 Share Posted January 20, 2013 A head scratcher. Doesn't make much sense to get both high and low voltage codes for the O2 sensor. I would have to guess that's going to be a loose connection, possibly a chafed wire. Air assist injector I'm not sure about. Would have to look it up in the FSM. What engine is in the car?

1 Lucky Texan Posted January 20, 2013 Share Posted January 20, 2013 I'd be tempted to do 2 things to begin with; Clear the codes and monitor how quickly/which ones return. Inspect for rodent damage to wires/hoses. Link to comment Share on other sites More sharing options...

ibroad Posted January 24, 2013 Author Share Posted January 24, 2013 Thanks guys. I checked/cleaned all the ground connections and also cleaned the battery terminals/posts. I reset the check engine light and it hasn't came back yet. Link to comment Share on other sites More sharing options...
