Detection Condition

PCM monitors input voltage from EGR boost sensor when monitoring conditions are met. If input voltage at PCM terminal 34 is more than 4.92 volts, PCM determines EGR boost sensor circuit is malfunctioning.

Monitoring Conditions

• Intake air temperature is more than 50 °F (10 °C).
• EGR boost sensor solenoid is turned OFF. (Barometric pressure is applied to EGR boost sensor.)

This is a Continuous Monitor (CM). MIL is illuminated when PCM detects malfunction during first drive cycle. Pending code is not available. Freeze frame data is available and DTC is stored in PCM memory.
