P0474
Exhaust Pressure Sensor "A" Circuit Intermittent
DTC P0474, sometimes indicated as P047400 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the auxiliary emissions system causing exhaust pressure sensor "a" circuit intermittent.
The exhaust pressure sensor measures the exhaust pressure in the exhaust manifold. The DTC P0474 is set when the engine control module (ECM) detects an intermittent signal from the exhaust pressure sensor.
Possible causes of the DTC P0474 are:
- Loose or corroded connector
- Defective exhaust pressure sensor
- Faulty wiring
The solutions for the DTC P0474 are:
- Check for loose or corroded connector
- Test the exhaust pressure sensor
- Check the wiring
- P0474: Exhaust Pressure Sensor A Circuit Intermittent
- P0474: Exhaust Pressure Sensor "A" Circuit Intermittent
- P0474: Exhaust Pressure Sensor "A" Circuit Intermittent/Erratic
- P0474: Exhaust Pressure Sensor CKT Intermittent
- P0474: Exhaust gas pressure sensor – circuit intermittent
- P0474 00: Exhaust gas pressure sensor - circuit intermittent
- P0474 00: Exhaust pressure sensor - intermittent failure
Bulletins are notices put out by manufacturers in conjunction with the NHTSA to notify the public of manufacturing issues or changes.
