Detection Condition

Diagnostic Trouble Code (DTC) is set when Powertrain Control Module (PCM) detects TP sensor voltage at PCM harness connector terminal "4V" above 4.8 volt after engine start. PCM determines that TP circuit has a malfunction. This is a continuous monitor (CCM). MIL illuminates if PCM detects malfunction conditions in 2 consecutive drive cycles. Pending code is not available. Freeze Frame Data is available and DTC is stored in the PCM memory.
