Pinpoint Test DT: Exhaust Pressure Sensor
Normal Operation and Fault Conditions
Refer to the DTC Fault Trigger Conditions.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Condition |
|---|---|---|
| PCM P0471:00 | Exhaust Pressure Sensor "A" Circuit Range/Performance: No Sub Type Information | Sets when the PCM detects the exhaust pressure sensor signal is not within a calibrated value. The exhaust pressure sensor reading should be greater than the BARO sensor reading by a calibrated threshold while the engine is running. |
| PCM P0472:00 | Exhaust Pressure Sensor "A" Circuit Low: No Sub Type Information | Sets when the PCM detects the exhaust pressure sensor signal is less than the PCM self test minimum. |
| PCM P0473:00 | Exhaust Pressure Sensor "A" Circuit High: No Sub Type Information | Sets when the PCM detects the exhaust pressure sensor signal is greater than the self test maximum. |
