Code Enable Criteria
Vehicle will need to be driven more than 50 MPH, and then allowed to decelerate. When vehicle is decelerating while meeting all criteria listed below, PCM will enable test to run. As test is running, you will see desired EGR parameter and EGR position sensor on scan tool change from 0 to a calibrated value above 0. For DTC to run, the following conditions must be met:
- DTCs P0101, P0102, P0103, P0107, P0108, P0112, P0113, P0117, P0118, P0121, P0122, P0123, P0201-P0206, P0300, P0336, P0403, P0404, P0405, P0502, P0503, P0506, P0507, P0604, P0606, P1106, P1107, P1112, P1114, P1115, P1120, P1121, P1122, P1125, P1220, P1221, P1374, P1404, P1514, P1515, P1516, P1517, or P1518 are not set.
- System voltage is 11-18 volts.
- AC status does not change.
- Transaxle range does not change.
- Throttle Position (TP) angle is less than 1 percent during deceleration.
- Intake Air Temperature (IAT) is less than 176°F (80°C).
- Engine Coolant Temperature (ECT) is more than 167°F (75°C).
- Engine speed is 900-1400 RPM.
- Idle Air Control (IAC) position is steady.
- Vehicle speed is more than 25 MPH during deceleration.
- Barometric Pressure (BARO) sensor more than 70 kPa.
DTC will set when MAP changes monitored during EGR flow test indicate insufficient EGR flow.
