Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-1600

Condition




The diagnostic trouble code (DTC) (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.
The diagnostic trouble code (DTC) (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
Calculated boost pressure.

Possible source

Signal too high
- Contact resistance or oxidation in the terminals
- Short-circuit to supply voltage in the signal cable
- Open-circuit in the signal cable
- Open-circuit in the signal ground cable
- Damaged boost pressure sensor.

Signal too low
- Short-circuit to ground in the signal cable
- Damaged boost pressure sensor.

Faulty signal
- Loose boost pressure sensor
- Contact resistance or oxidation in the terminals
- Damaged boost pressure sensor.

Fault symptom[s]
- Malfunction indicator lamp (MIL) lit
- Poor performance.
