Conditions For Running DTC
- DTCs P0101-P0103, P0107, P0108, P0112, P0113, P0116, P0117, P0118, P0121-P0123, P0201-P0206, P0300, P0336, P0403, P0404, P0502, P0503, P0506, P0507, P1106, P1107, P1111, P1112, P1114, P1115, P1121, P1122, P1374, or P1404 not set.
- Ignition 1 signal parameter is 11-18 volts.
- A/C status does not change.
- The Current Gear parameter does not change.
- Intake Air Temperature (IAT) sensor parameter is 32-212°F (0-100°C).
- Engine Coolant Temperature (ECT) sensor parameter is more than 167°F (75°C).
- Engine speed parameter is 1050-1400 RPM.
- Manifold Absolute Pressure (MAP) sensor parameter is between 15-70 kPa.
- Mass Airflow (MAF) sensor parameter does not change more than 2 grams per second.
- Barometric Pressure (BARO) parameter is more than 74 kPa.
- Throttle Position (TP) sensor parameter is less than 1 percent.
- Vehicle Speed sensor parameter is more than 30 MPH (48 km/h) during deceleration.
- Idle Air Control (IAC) Position parameter does not change more than 5 counts while the conditions are met.
- The vehicle will need to be driven faster than 50 MPH and then allowed to decelerate. When vehicle is decelerating while meeting all of the criteria listed above, the PCM will enable the test to run. As the test is running, you will see the Desired EGR parameter and EGR position sensor on scan tool change from zero to a calibrated value greater than zero. Additionally, EGR Flow Test Count parameter on scan tool will increment when each EGR flow test is completed.
