Conditions For Running DTC
- DTCs P0101, P0102, P0103, P0107, P0108, P0112, P0113, P0116, P0117, P0118, P0121, P0122, P0123, P0201, P0202, P0203, P0204, P0205, P0206, P0300, P0336, P0403, P0404, P0502, P0503, P0506, P0507, P1106, P1107, P1111, P1112, P1114, P1115, P1121, P1122, P1374, or P1404 are not set.
- Ignition 1 signal parameter is 11-18 volts.
- The AC relay command parameter does not change.
- Transaxle range does not change.
- Intake Air Temperature (IAT) is more than 176°F (80°C).
- Engine Coolant Temperature (ECT) is more than 167°F (75°C).
- Engine speed is 1050-1400 RPM.
- Manifold Absolute Pressure (MAP) is steady between 15-70 kPa.
- Mass Airflow (MAF) sensor parameter does not change more than 2 grams per second.
- Barometric (BARO) pressure sensor is more than 74 kPa.
- Throttle Position (TP) sensor parameter is less than one 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 the 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 the EGR position sensor on the scan tool change from zero to a calibrated value more than zero. Additionally, the EGR Flow Test Count parameter on the scan tool will increment when each EGR flow test is completed.
