Detection Condition

Diagnostic Trouble Code (DTC) is set if Powertrain Control Module (PCM) detects throttle valve opening angle is below 12.5 porcent for 5 seconds after following conditions are met, PCM determines that TP is stuck close:

• ECT is above 158°F (70°C).
• MAF sensor signal above 8.36 lb/min (63.2 g/sec).

DTC is also set if PCM detects throttle valve opening angle is above 50 porcent for 5 seconds after following conditions are met, PCM determines that TP is stuck open:

• Engine speed above 500 RPM.
• MAF sensor signal below 0.7 lb/min (5.3 g/sec).

This is a continuous monitor (CCM). MIL illuminates if PCM detects the malfunction conditions in 2 consecutive drive cycles. Pending code is available if PCM detects malfunction condition during first drive cycle. Freeze Frame Data is available and DTC is stored in the PCM memory.
