P0031 Engine Code Repair
Meaning of P0031 engine trouble code is a kind of powertrain trouble code and P0031 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.
P0031 Fault Symptoms :
- Check engine light comes on
- Engine stalling or misfiring
- Engine performance issues
- Car not starting
If one of these reasons for P0031 code is occuring now you should check P0031 repair processes.
Now don't ask yourself; What should you do with P0031 code ?
The solution is here :
P0031 Possible Solution:
Power Steering Pressure (PSP) Switch Signal Malfunction The PCM counts the number of times vehicle speed transitions from 0 to a calibratable speed. After a calibratable number of speed transitions the PCM expects that the PSP input should have changed. This DTC is set if the transition is not detected. Vehicle towed with engine running Power steering hydraulic concern was repaired but DTC was not erased PSP switch/shorting bar damaged SIG RTN circuit open PSP circuit open or shorted to SIGRTN PCM damaged Check, if possible, if vehicle was towed or power steering service was performed. Observe PSP V PID while checking wires for intermittents.

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.
P0031 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP0031 OBD-II Trouble Code Oxygen Sensors (O2S) or Heated Oxygen Sensors (HO2S) need to reach a minimum operating temperature of 750 degrees F to produce an accurate voltage signal. The faster the heated oxygen sensor reaches t P0031 code.Main reason For P0031 CodeThe reason of P0031 OBD-II Engine Trouble Code is Injector Circuit Malfunction - Cylinders. |
P0031 the main thing to check is to verify the operation of the VCT solenoid. You're looking for a sticking or stuck VCt solenoid valve caused by contamination. Refer to vehicle specific repair manual to perform component tests for the VCT unit.
