Diagnostic trouble code (DTC) information
Condition
Diagnostic trouble code (DTC) ECM-1600 (signal too high or too low) is stored if the signal from the boost pressure sensor is outside its normal range. The fault is diagnosed by the control module when the ignition is on / the engine is running.
Diagnostic trouble code (DTC) ECM-1600 (faulty signal) is stored if the signal from the boost pressure sensor is within its normal range but deviates from the calculated boost pressure. The fault is diagnosed by the control module when the engine is running.
Substitute Value
Limited boost pressure (if the signal is too high).
Possible Source
Signal too high:
- Contact resistance in the terminals
- Short-circuit to supply voltage in the signal cable
- Open-circuit in the signal cable
- Defective boost pressure sensor.
Signal too low:
- Short-circuit to ground in the signal cable
- Defective boost pressure sensor.
Faulty signal:
- The boost pressure sensor has come loose
- Contact resistance in the terminals
- Defective boost pressure sensor.
Fault symptom[s]
- Malfunction indicator lamp (MIL) lit
- Poor performance.
