P212B - OBD Trouble Code

<<See All OBD Codes

The trouble code P212B can be explained as Throttle Position Sensor G Circuit Range/Performance. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

Do you want to know more about the P212B fault code? Don’t worry! Parts Avatar Canada is here at your service. If the engine control module would detect a variation in the voltage coming from the throttle position sensor/switch G circuit signal that is outside the parameters set by the automobile manufacturer, then it would store the P212B error code. This would also give rise to the illumination of the check engine light.

What causes this problem with the Throttle Position Sensor G Circuit Range/Performance?

• The throttle return spring might be sticking
• MAP or TPS connector might be flawed
• Unusable accelerator pedal position assembly
• There can be distorted PCM
• Quirks in the throttle control motor

1. Pedal Position Sensor - The accelerator pedal position sensor is monitored by the ECU and is one of those constituents which will trigger an error code in the ECU when a fault arises. It would also give rise to the illumination of the check engine light on the dashboard. Buy top notch pedal position sensor from us at economical prices.
2. Engine Control Module - If there is any corrosion or breaks in the internal wiring of the harness, then it can cause a short in the ECM or can also cause corrosion in the ECM through the wiring harness. You can always rely on us as we have best auto parts for our customers.
3. Throttle Position Sensor - Are you experiencing sudden idle surges and sudden hesitation while accelerating? Then these are the symptoms of defective throttle position sensor. Get it checked and replace if needed.
4. Powertrain Control Module - The onboard computer, or powertrain control module is the brain of the engine control system. Now if the brain is not working properly, then neither is the car engine. Get it replaced before the situation gets worse.
5. Electronic Control Unit - Is your car jump starting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So it is very important to replace the defective electronic control unit with us at equitable prices.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P212B code to be stored:

• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• Most often he has to inspect the throttle position sensor itself to see if they are faulty or damaged. Additional error codes that are stored in the vehicle are also addressed.
• The mechanic performs a continuity test between the PCM and solenoid to check the resistance.
• If the solenoid or the control modules are not faulty, he will then retune the code and test drive the vehicle.
• On test driving, if the P212B code does not return soon, he will know that an erratic condition exits.
• But if the error returns instantaneously, he will check every components of the control module as well as the circuit like connectors, wires, harness, fuses etc for any possible fault.
• If any component is damaged, he will fix them right away.
• After performing this repair, he will inspect the throttle position sensor as well.
• If the level is below the manufacturer’s specification, it has to be refilled and if the fluid is murky or contaminated it needs to be replaced.
• Every time a repair work is carried out, make sure that the mechanic test drives the vehicle after every repair so that the diagnosis is successful. This can eventually help him to know as to where the error occurred.

Common Mistakes When Diagnosing The P212B 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.
• Most of the times the mechanics might simply replace the wrong auto part, while in reality the issue might be with the throttle position sensor circuit.
