Detection Condition

PCM monitors voltage from EGR boost sensor when Intake Air Temperature (IAT) is more than 50°F (10°C) and EGR boost sensor solenoid is turned off (atmospheric pressure is applied to sensor). DTC is set when input voltage from EGR boost sensor is more than 4.8 volts. This is a Continuous Monitor (CM). MIL is illuminated when 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.
