Hello everyone.
I need help/advice for a 2012 Chevrolet Equinox 2.4L LT.
It has the famous P2138 DTC and reduced engine power on the instrument cluster.
Measured all 6 inputs and outputs (as mitchell1 said)
Attachment not found
of the APP 1 and App 2 sensor at the computer and also at the connector, all are okay.
Even snipped the accelerator connector and soldered it right at the ECU to bypass the X206 and X212 connectors but still the same DTC.
Can I say that it is the ECU that's faulty?
