Detection Condition

Diagnostic Trouble Code (DTC) is set when Power Control Module (PCM) monitors input voltage from Exhaust Gas Recirculation (EGR) boost sensor when monitoring conditions are: Intake Air Temperature IAT is above 10°C (50°F) and EGR boost sensor solenoid is turned off (BARO is applied to EGR boost sensor). If input voltage at PCM terminal "4AE" is below 0.21 volts, PCM determines that EGR boost sensor circuit is malfunctioning. This is a continuous monitor (CCM). MIL illuminates if PCM detects the malfunction condition during first drive cycle. Pending code is not available. Freeze Frame Data is available and DTC will store in the PCM memory.
