I recently scanned mytruck and I had a code come up I cannot remember what the code was. I found to test the yellow wire with dark green on pin 10 on the TCM to see if the PCM is putting out to much voltage. I should put out twelve volts but it is putting out over fourteen volts, but my truck runs fine no problems. There is a chip tune on it but we cannot find the chip to remove it if that could be it or not.
have the same problem?
