P0472 Engine Code Repair
Meaning of P0472 engine trouble code is a kind of powertrain trouble code and P0472 code can be about replacing a broken oxygen sensor can eventually lead to a busted catalytic convertor which can cost upwards of $2,200. Taking your car into a shop will cost you around $210 depending on the car. However, an oxygen sensor is easy to replace on many cars and is usually detailed in the owner's manual. If you know where the sensor is, you only have to unclip the old sensor and replace it with a new one. Regardless of how you approach it, you should get this fixed right away.
P0472 Fault Symptoms :
- Check engine light comes on
- Engine stalling or misfiring
- Engine performance issues
- Car not starting
If one of these reasons for P0472 code is occuring now you should check P0472 repair processes.
Now don't ask yourself; What should you do with P0472 code ?
The solution is here :
P0472 Possible Solution:
Air Conditioning Pressure Sensor (ACP) Insufficient Pressure Change Each time the A/C clutch engages, the PCM is looking for a pressure change in the refrigerant. If the change in pressure is outside of the calibration the DTC will set. A/C system mechanical failure Open ACP or VREF circuit A/C sensor damaged A/C system electrical failure A/C clutch always engaged Verify A/C system function, including refrigerant charge.
P0472 Code Meaning :

OBD-II Diagnostic Powertrain (P) Trouble Code For Engine
0
Intake Valve Control Solenoid Circuit Low
4
Throttle/Pedal Position Sensor/Switch A Circuit Intermittent
7
Cylinder 4 Contribution/Balance Fault
2
Crankshaft Position Sensor A Circuit Low Input
The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate.
P0472 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP0472 OBD-II Trouble Code The Exhaust Back Pressure (EBP) sensor is a variable capacitance sensor that, when supplied with a 5-volt reference signal from the Engine Control Module ( P0472 code.Main reason For P0472 CodeThe reason of P0472 OBD-II Engine Trouble Code is Throttle/Pedal Position Sensor/Switch A Circuit Intermittent. |
P0472 DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.
