The Engine Control Module (ECM) detects the following conditions: •The difference between desired boost and actual boost is greater than 20 kPa (80 inch of H2O) for more than eight seconds.•Desired boost is not ZERO.•The ECM has been powered for at least two seconds. This engine utilizes a wastegate control valve that is electronically controlled in order to precisely regulate the boost pressure. The Engine Control Module (ECM) monitors the signal from the boost pressure sensor in order to determine the boost pressure in the intake manifold. The ECM uses this information and other information that is related to the...

Vehicle speed is greater than 127 mph (204 km/h) for at least two seconds.

Vehicle speed is changing faster than is possible. If the progammed VSL Protection is progammed to 3000 rpm this diagnostic will not occur.

The Engine Control Module (ECM) detects the following conditions: •The signal for boost pressure has been more than 172 kPa (25 psi) for more than 0.5 seconds.•The fuel rate is 80% of the maximum value for the current torque map.•102-03 diagnostic code is active. This engine utilizes a wastegate control valve that is electronically controlled in order to precisely regulate the boost pressure. The Engine Control Module (ECM) monitors the signal from the boost pressure sensor in order to determine the boost pressure in the intake manifold. The ECM uses this information and other information that is related to the...

The Engine Control Module (ECM) detects the following conditions: •The intake manifold air temperature is equal to 90 °C (194 °F) or above 90 °C (194 °F).•The engine coolant temperature is greater than 99 °C (210.2 °F).•The engine has been running for at least 30 seconds. Note: This diagnostic code represents a critical event. This diagnostic code does not represent an electronic system fault. Possible Causes: 1) Sensor failure2) Sensor connector/harness3) Check connection at ECM and harness between sensor & ECM
