P212D OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P212D can be elucidated as Throttle Position Sensor/Switch G Circuit High Input. If the P212D error code is appearing, then it would mean that a high voltage input from the throttle position sensor (TPS) circuit or a particular pedal position sensor (PPS) circuit has been detected by the powertrain control module. The "G" here would mean a specific circuit, sensor, or area of a certain circuit.

Are you tensed because the P212D fault code is flashing? We have everything which you will need to fix it and that too at equitable prices. We promise that you will never regret your decision. 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. 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.

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

• There might be an open or shorted circuits between the TPS, PPS, and the powertrain control module
• There might be inoperative TPS or PPS
• Some electrical connectors might be corroded
• Unusable drive-by-wire actuator motor

1. Engine Control Module - Dead cells in batteries can cause a failure in the engine control module. Many times a battery is left in the rig long after a cell has died. This would affect the grounding in the car battery.
2. Throttle Position Sensor - If you find out that there are no misfire codes and a common cause of acceleration stumble is a faulty throttle position sensor. So it is very important to replace the throttle position sensor with us at equitable prices.
3. Powertrain Control Module - If there are some faults in the PCM, then it may throw off the timing and fuel settings of the engine, which can negatively affect the performance. A flawed PCM may cause the vehicle to experience a reduction in fuel efficiency, power as well as acceleration.
4. Pedal Position Sensor - The APP sensor essentially tells your car engine that how fast or slow to drive as you will press the gas pedal. When you press down or lift off the throttle, it would send an electrical signal to the vehicle’s ECU or ECM and then would transmit that signal to the fuel system.

5. Electronic Control Unit - Do you know that the poor performance or unexplained drops in fuel economy or efficiency are often associated to onboard car computer problems, or defective ECU issues? 
6. Diagnostic Tools - Use factory grade diagnostic tools to resolve OBD code P212D error. Buy new diagnostic tools and equipment for us.

You might be thinking that how would you diagnose these problems? We at Parts Avatar Canada would help you diagnose the major symptoms easily.

Common Symptoms

• Visibility in the check engine light
• Pushed throttle (at any RPM)
• No acceleration at all
• Car engine might start stalling when allowed to idle
• Reluctance when accelerating
• Cruise control might not function properly

Looking out for some ways with the help of which you can correct this fault code? Then you have arrived at the correct place. We are here to help you out, so you must check out the steps mentioned below as follows:

• Repair or replace the quirky TPS
• Rehabilitate the defaults in the electronic control unit
• The malfunctioning PPS should be repaired or replaced as per the need
• Carefully adjust the faults in the drive-by-wire actuator motor
• The PCM/ECM should be restored to working order

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. 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:

After verifying the P212D code with an OBD-II scanner, the mechanic should begin with a visual inspection of all electrical components, especially looking for some issues in the throttle position sensor. Any issues should be repaired, and the code should be cleared from the system. If the code reappears after a retest, the mechanic should then move on to performing voltage tests and resistance tests on the sensor, and comparing the information to the manufacturer’s specifications. If the readings are within the correct limits, then the sensor needs to be replaced. However, if the readings are not within the correct limits, then the issue lies elsewhere. The mechanic should continue checking each possible cause, clearing the code and retesting the system after each attempt, to be sure that the correct solution is found.

Common Mistakes When Diagnosing The P212D Code

The most common mistake while diagnosing this code is missing out on diagnosing steps which further leads to the expensive and unnecessary replacements. It is always recommended to seek help of experienced diagnostician to avoid any mistakes.
