P1255 Engine Trouble Code

Meaning of P1255 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 $240-$400 depending on the car, but that's usually the cost of parts because the labor is relatively simple.

P1255 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 P1255 code is occuring now you should check P1255 repair processes.
Now don't ask yourself; What should you do with P1255 code ?
The solution is here :

P1255 Possible Solution:

P1255 Engine

The crankshaft sensor signals the fuel injection computer or the ignition control when the cylinders are firing. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time.If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. In later car models, the car's computer can usually keep the vehicle running, but the engine warning light on the dashboard goes on to warn the driver.

P1255 Code Meaning :

P 1 2 5 5
OBD-II Diagnostic Powertrain (P) Trouble Code For Engine Fuel And Air Metering Manifold Absolute Pressure/Barometric Pressure Circuit High Input Cylinder 1 Injector Circuit Low Crankshaft Position Sensor B Circuit Malfunction

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.

P1255 OBD-II Diagnostic Powertrain (P) Trouble Code Description

P1255 OBD-II Trouble Code Pedal Correlation PDS2 and LPDS Low is one of the definitions for the P1255; however your vehicles manufacturer may have a different definition for the P1255 code. Please check below for your specific P1255 code.

Main reason For P1255 Code

The reason of P1255 OBD-II Engine Trouble Code is Manifold Absolute Pressure/Barometric Pressure Circuit High Input.

P1255 DTCs may also be triggered by faults earlier down the line. For example, a dirty MAF sensor might be causing the car to overcompensate in its fuel-trim adjustments. As a result, oxygen sensors are likely to report fuel mixture problems.
