Detection Condition

PCM monitors input voltage from Exhaust Gas Recirculation (EGR) boost sensor when monitoring conditions are:

Monitoring Conditions

• Intake Air Temperature (IAT) is more than 50°F (10°C).
• EGR boost sensor solenoid is turned off (BARO is applied to EGR boost sensor).

If input voltage at PCM terminal "4AE" is less than 0.21 volt, PCM determines that EGR boost sensor circuit is malfunctioning. This is a Continuous Monitor (CM). MIL illuminates if PCM detects malfunction condition during first drive cycle. Pending code is not available. Freeze Frame Data is available and DTC will store in PCM memory.
