Error Code P212C: What It Means & What To Do?

<<See All OBD Codes

The trouble code P212C can be described as Throttle Position Sensor G Circuit Low Input. The error code P212C would start triggering when the PCM would detect some fault in throttle position sensor/switch G circuit. One thing which you must keep in mind that its symptoms as well as causes would surely vary as it depends upon a number of things.

This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code. The P212C trouble code would indicate that a throttle position sensor/switch G circuit signal which is not as per the predetermined limit has been detected by the ECM. Now when this would occur, the fault code would be stored and there would be an illumination in the malfunction indicator light.

What causes this problem with the Throttle Position Sensor G Circuit Low Input?

• The TPS might not be mounted correctly
• Malfunctioning accelerator pedal position assembly
• Some issues related to the TPS circuit short to ground
• Broken powertrain control module
• The TPS might not be functioning properly
• Defective throttle control motor

1. Engine Control Module - Is your car engine light still staying ON after resetting or your car engine is turning off for no reason? Then these are some common symptoms indicating that your car engine control module is defective.
2. Pedal Position Sensor - If the APP sensor is not working properly, then it would also lead to some issues related with fuel efficiency. Get it replaced before the situation gets worse.
3. Powertrain Control Module - The PCM works as the central computer system in an automobile’s mechanism. This auto part is the in charge of all the constituents as well as the functions performed by them. Having such enormous importance in the operation of all the parts means that any defect in it will affect almost every aspect of a car.
4. Throttle Position Sensor - Did you just face sudden engine stalling without any apparent reason? Don’t waste time as it is an indication that there are some quirks in your throttle position sensor. Don’t waste time and get it replaced or else P212C code can turn up.
5. Electronic Control Unit - The ECU is a major component of your car's onboard computer. It's used to regulate many systems and subsystems in your car's engine, drive train and other major components. Visit us to buy best quality ECU online.

Common Symptoms

• Illumination in the service engine soon light
• Uneven or less idle
• Issues related to car engine stalling
• Problem of surging
• The acceleration might be very less
• Presence of some other symptoms as well
• Decreasing engine performance

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P212C:

• It is essential to restore the flawed throttle control motor
• Rehabilitate the defaults in the throttle position sensor circuit
• The malfunctioning powertrain control module should be repaired or replaced as per the need
• Carefully adjust the faults in the accelerator pedal position assembly
• The TPS circuit should be restored to working order

Have a look at our superior variety of pedal position sensor, accelerator pedal assembly; throttle position sensor connector, tps sensor, electronic throttle control, body control module, ecm car, throttle body sensor, idle control valve and many more. Now all your problems would vanish within no time.

Here are some steps which you should follow in order to diagnose this fault code:

• Use an OBD-II scanner in order to verify that the code is present, and check for other codes for any other type of error or problem that might need attention.
• The current data along with freeze frame data are recorded, and the codes are then cleared to see if they reoccur.
• The vehicle is inspected for any problems with the wiring and connectors to check for loose connections, corrosion, or shorts.
• The tests related to the throttle position sensor and components may help pinpoint the problem, as well as inspection of the current sensor and cut off switch will further helping the cause.
• The P212C error is triggered if there is a physical problem with the throttle position sensor which could cause the engine performance to go off.

Common Mistakes When Diagnosing The P212C Code

• There can be a lot of issues which might appear when the P212C error code start flashing up.
• Many a times the mechanic might not react properly and would just replace the throttle position sensor when in reality the simpler components should be checked first properly.
