P2120 Engine Trouble Code
Meaning of P2120 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.
P2120 Fault Symptoms :
If one of these reasons for P2120 code is occuring now you should check P2120 repair processes.
Now don't ask yourself; What should you do with P2120 code ?
The solution is here :
P2120 Possible Solution:
Power Steering Pressure (PSP) Switch Malfunction In Key On, Engine Off Self-Test, this DTC indicates the PSP input to the PCM is high. In Key On, Engine Running Self-Test, this DTC indicates that the PSP input did not change state. Steering wheel must be turned during Key On, Engine Running Self-Test PSP switch/shorting bar damaged SIG RTN circuit open PSP circuit open or shorted to SIGRTN PCM damaged.
P2120 Code Meaning :
|OBD-II Diagnostic Powertrain (P) Trouble Code For Engine||Fuel And Air Metering (Injector Circuit Malfunctions Only)||Fuel Rail/System Pressure - Too High||Turbocharger Boost Sensor A Circuit Low||Shift Solenoid E Performance or Stuck Off|
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.
P2120 OBD-II Diagnostic Powertrain (P) Trouble Code DescriptionP2120 engine trouble code is about Shift Solenoid E Performance or Stuck Off.
Main reason For P2120 CodeThe reason of P2120 OBD-II Engine Trouble Code is Fuel Rail/System Pressure - Too High.
P2120 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.
