P0231 Engine Trouble Code

Meaning of P0231 engine trouble code is a kind of powertrain trouble code and theoretically you can drive for a few weeks or even months with a broken MAF sensor. You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. At a shop, the replacement cost is between $200-$300 depending on the car, but that's usually the cost of parts because the labor is relatively simple.

P0231 Fault Symptoms :

  1. Check engine light comes on
  2. Engine stalling or misfiring
  3. Engine performance issues
  4. Car not starting
If one of these reasons for P0231 code is occuring now you should check P0231 repair processes.
Now don't ask yourself; What should you do with P0231 code ?
The solution is here :

P0231 Possible Solution:

P0231 Engine

Gasoline engines use spark plugs to cause an explosion of fuel within the cylinder. In a properly timed engine, this explosion occurs at the proper moment to send the piston to the bottom of the cylinder and provide power to the drive shaft. If the plug wires are out of sequence, the explosion occurs at the wrong time. The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank. As a result, the engine stutters or backfires, if it runs at all.

OBD-II Diagnostic Powertrain (P) Trouble Code For Engine Intake Valve Control Solenoid Circuit Low Manifold Absolute Pressure/Barometric Pressure Circuit High Input Injection Pump Fuel Metering Control 'A' High (Cam/Rotor/Injector) Crankshaft Position Sensor A Circuit Low Input

The poor running symptoms are consistent with a MAP sensor malfunction. In addition, in some cases, a bad MAP sensor will not throw a code. Again, the ELD code likely represents a separate wiring issue.

Main reason For P0231 Code

The reason of P0231 OBD-II Engine Trouble Code is Manifold Absolute Pressure/Barometric Pressure Circuit High Input.

P0231 DTC specifically refers to the camshaft (cam) timing. In this case, if the cam timing is over-retarded, the engine light will be illluminated and the code will be set.
