Guide To P0220 OBD Error Code Solutions

<<See All OBD Codes

The fault code P0220 can be defined as throttle/pedal position sensor/switch circuit B malfunction. This error code would mean that the vehicle’s powertrain control module has detected a voltage or resistance reading which is outside of specifications that were set by the manufacturer for this circuit.

The electric throttle control actuator consists of throttle control motor, throttle position sensor etc. The throttle position sensor would respond to the movement of the throttle valve. There are two sensors in the throttle position sensor.

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.

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

• The components of the throttle’s electrical system might be loose or disconnected
• Damaged wiring or connectors can be associated with the throttle’s electrical system
• A malfunction within the throttle body
• Some faults in the throttle position sensor
• A faulty accelerator pedal position sensor
• An accelerator pedal or throttle position sensor that is out of alignment
• Defective powertrain control module

1. Throttle Position Sensor - There can be some issues with the Throttle Position Sensor due to which you may see P0220 code appearing over and over again. Visit us to buy best quality Throttle Position Sensor online.
2. Pedal Position Sensor - A lot of issues can arise do to defective Pedal Position Sensor. Did you just see P0220 code flashing? Now you know the reason why it is appearing. Get it inspected and replaced on time.
3. Powertrain Control Module - Faulty Powertrain Control Module can be the reason why P0220 code is flashing. Visit us to purchase top notch Powertrain Control Module online.
4. Accelerator Position Sensor - It is an important auto part which needs full care. A faulty Accelerator Position Sensor can be a reason behind the flashing up of P0220 code.
5. Engine Wiring Connector - OBD Code P0220 can appear because of faulty Engine Wiring Connector. 

It is vital to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0220 here:

Common Symptoms

• There can be an illumination in the malfunction indicator lamp
• Misfiring at idle or at highway speed
• The idle quality can be poor
• Possibly won't idle
• Possibly starts and stalls

Want to correct the Trouble Code P0220? Read these points mentioned below:

• Make sure that you replace the throttle position sensor
• Replacing the accelerator pedal position sensor
• If there are some issues with the throttle body, then it should be replaced
• You can always replace the powertrain control module
• Repairing or replacing wiring that is associated with the throttle’s electrical system
• Realigning the throttle position sensor or accelerator position sensor to its correct position

You must follow these steps mentioned below to diagnose this fault code:

• A mechanic can diagnose the P0220 code by first inspecting the throttle body and the accelerator pedal for any wiring that may be damaged or disconnected
• The mechanic would also check to ensure that all sensors appear to be in alignment and installed properly. If any issues were found during this inspection, the mechanic would need to resolve them before continuing this diagnosis
• If all of the above-mentioned tasks have been performed by the mechanic, he would then test the throttle position sensor and the pedal position sensor for proper function. If either of these two sensors test bad, the replacement of the sensor would likely resolve this issue.
• If the sensors proved to be functional, the problem may be within the powertrain control module.

Common Mistakes When Diagnosing The P0220 Code

A lot of people generally make mistake of replacing the throttle position sensor, the pedal position sensor or both since these parts are mentioned in the actual definition while diagnosing the P0220 fault code. Because of this, it can lead to misdiagnosis. Keep this thing in mind that if a part is mentioned in the trouble code definition, then it does not mean that it is the part which is causing problem.
