P212A - OBD Trouble Code

<<See All OBD Codes

The trouble code P212A can be defined as Throttle Position Sensor/Switch G Circuit Malfunction. A potentiometer which is mounted to the throttle body is a throttle position sensor. It notices the throttle blade angle. Now when the throttle blade would move, then a signal would be sent to the powertrain control module by the TPS. Generally a three wire sensor: A 5 volt reference from the PCM to the TPS, a ground from the PCM to the throttle position sensor and a signal return from the throttle position sensor to the PCM.

It is always good to learn more! That is the reason why we are here to help you out in gaining more knowledge about the P212A error code. The throttle position sensor/switch G circuit is being monitored by the engine control module. This trouble code would be set by the ECM when the throttle position sensor/switch G circuit signal would not be as per the specifications set by the manufacturer. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

What causes this problem with the Throttle Position Sensor/Switch G Circuit Malfunction?

• Faulty harness
• Malfunctioning MAP or TPS connector
• Some issues related to the throttle return spring
• Unusable TPS
• Imperfect throttle control motor
• There can be distorted PCM
• The accelerator pedal position assembly might not be functioning properly

1. Throttle Position Sensor - Is there a sudden bucking as well as jerking in your automobile. Then in that case there is surely some fault in the throttle position sensor. Buy top notch throttle position sensor from us at economical prices.
2. Engine Control Module - There can be some engine performance issues due to faulty engine control module. If the ECM fails or has any problems it can lead to performance issues with the vehicle like misfires, hesitation, loss of power, and sometimes even decreased fuel economy.
3. Pedal Position Sensor - The accelerator pedal position sensor is fixed to the accelerator pedal and it can sense what position the pedal is in. A change in the position of the pedal would lead the sensor to change the electric voltage which it supplies. So if there are some faults in your pedal position sensor, then replace it soon!
4. Powertrain Control Module - PCM stands for powertrain control module. It is a car part, a control unit which is utilized on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU).
5. Electronic Control Unit - If your automobile's check engine light remains on constantly, and never goes off, there's a good chance that your vehicle has a damaged electronic control unit. There are a lot of reasons why a car's check engine light will remain on. The most common reason is a defective ECU.
6. Diagnostic Tools - It is always advisable to use correct tools and equipment while resolving any OBD code issue as even small mistakes can lead to wrong diagnosis. Thus, always take help from a professional who has the knowledge and experience to such tools in efficient manner. Buy new quality diagnostic tools from us today!

Common Symptoms

• The service engine soon light can start lighting up
• There can be misfiring at idle or at highway speed
• The quality of the idle might be poor
• Some issues related to starting and stalling of car engine
• Decline in the performance of the car engine

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 P212A:

• You must fix the defective harness
• Make sure to mend the faulty MAP or TPS connector
• It is essential to restore the flawed throttle return spring
• Repair or replace the quirky throttle control motor
• Rehabilitate the defaults in the accelerator pedal position assembly
• The malfunctioning powertrain control module should be repaired or replaced as per the need

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

• This is a general type of error code which is diagnosed with the help of a scanner.
• The mechanic will insert a scanner to diagnostic port of the vehicle and recover the codes and freeze frame data.
• If he happens to find any additional error codes, he has to address them as well.
• Once it is done, he has to reset the vehicle, and then test drive to see if the error code appears.
• If the error code does not return, then there can be an erratic condition.
• Then the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective.
• Check for the damaged throttle position sensor and its components for error. It the mechanic finds the fault in the connectors in relation to the throttle position sensor, replace it immediately.
• Also check for the particular battery cells emitting high voltages and thus might need battery replacement as well.
• Parts or components should not be replaced with reference to only a P212A DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
• If all the components seems to work perfectly, inspect the PCM for faults and replacement along with reprogramming.

Common Mistakes When Diagnosing The P212A Code

• A lot of people make a big mistake of attempting to diagnose the throttle position sensor first. Save yourself a big headache and make sure that you are addressing the defective harness or poor electrical connection before beginning your diagnosis.
• Common mistakes while diagnosing this trouble code are unnecessary and expensive replacements which usually happen when one don’t follow all the steps carefully.
