Conditions For Running DTC
WARNING: This page is about a different car, the 2003 GMC Savana and 2003 Chevrolet Chevy Express. However, it is still accessible from the selected car via links, so may be relevant.
- DTCs P0101, P0102, P0103, P0107, P0108, P0112, P0113, P0117, P0118, P0121, P0122, P0123, P0200, P0300, P0335, P0336, P0404, P0500, P0502, P0503, P0506, P0507, P0562, P0563, P1125, P1404 are not set.
- The ignition 1 signal parameter is between 11-18 volts.
- The Throttle Position (TP) sensor parameter is less than 1.2 percent.
- The Intake Air Temperature (IAT) sensor parameter is between 32-212° F (0-100° C).
- The Engine Coolant Temperature (ECT) sensor parameter is more than 140° F (60° C).
- The engine speed parameter is between 725-1700 RPM.
- The Manifold Absolute Pressure (MAP) sensor parameter is between 17-42 kPa.
- The Mass Air Flow (MAF) sensor parameter is more than 25 mph during deceleration.
- The Barometric Pressure (BARO) is more than 74 kPa.
- The vehicle will need to be driven at more 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 EGR flow test to run. As the EGR flow test is running, you will see the Desired EGR position parameter and the EGR position sensor parameter in the scan tool momentarily change from 0 to a calibrated value above 0.
