Error Code P0222: What It Means & What To Do?

<<See All OBD Codes

The P0222 can be defined as throttle/ pedal position switch/ sensor B circuit low input. A range of acceptable voltage is specified by the manufacturer which can be produced from the throttle position sensor. The P0222 code would indicate that the voltage which has been produced by the throttle position sensor has been detected by the engine control module has fallen below this specification.

Want to learn something more about this fault code? The electronic throttle control actuator comprises of throttle control motor, throttle position sensors etc. The throttle position sensor would respond to the throttle valve movement.

There are two sensors in the throttle position sensor. These sensors are a type of potentiometers which can transform the throttle valve position into the output voltage and would start emitting the voltage signal to the engine control module. These sensors also help in detecting the opening as well as closing speed of the throttle valve and would feed the voltage signals to the engine control module.

The engine control module would judge the current opening angle of the throttle valve from these signals and the engine control module would control the throttle control motor to make the throttle valve opening angle properly in response to the driving condition.

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

• Faults in the engine control module
• The throttle body can start malfunctioning
• Throttle position sensor that is out of alignment
• Unplugged or damaged wiring might be associated with the throttle position sensor

1. Throttle Position Sensor - A faulty Throttle Position Sensor can be troublesome. You can always rely on us as we have best auto parts for our customers.
2. Engine Control Module - If everything is alright with Throttle Position Sensor, then there is surely some defect in Engine Control Module. Get it replaced before the situation gets worse.
3. Powertrain Control Module - P0222 code can display due to some defects in the Powertrain Control Module. So, it is very important to replace the Powertrain Control Module with us at equitable prices.
4. Digital Multimeter - Willing to buy Digital Multimeter online? We are here at your service!

For us our customers are everything, and that’s why we will help you to diagnose P0222 code by mentioning some important symptoms below:

Common Symptoms

• The acceleration might be poor
• There can be a loss of power
• Engine may be hard to start or not start at all
• Accelerator pedal might be unresponsive
• There can be an illumination in the check engine light

Learn the ways with which you can correct this trouble code:

• Replace the throttle position sensor
• Plugging in, repairing, or replacing wiring or circuitry that is associated with the throttle position sensor
• The throttle body should be repaired or replaced
• If there are some issues with the engine control module, then it should be replaced
• You can always realign the throttle position sensor 

Don’t get tensed if you are still facing any of these issues as we care for our customers and that’s why we offer a good range of Throttle Return Spring, Automatic Transmission Module, Throttle Body Spacer and Tps sensor and a lot more. We are sure that now all your issues would be resolved.

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

This fault code can be diagnosed by the mechanic by visually inspecting the throttle body and everything related with it for damages and faults. This would include making sure the throttle position sensor is mounted to the throttle body correctly and that the throttle body itself is operating properly

This inspection would also be done to make sure all electrical connectors are plugged in and properly secured. If everything associated with the throttle body passes the visual inspection, then the next step would be to test the throttle position sensor for proper voltage with a digital multimeter using the manufacturer’s recommended procedure

If the throttle position sensor fails the voltage test, the mechanic would then replace the throttle position sensor at the customer’s request. If the voltage test has been passed by the throttle position sensor, the mechanic would then use a high-tech scan tool to test the engine control module for faults, as it is one of the last parts unchecked in this system

Common Mistakes When Diagnosing The P0222 Code

This is one of the worst mistakes that someone can make when attempting to diagnose a check engine light. If a part is mentioned in a trouble code definition, then it does not mean that the part is faulty. In fact, it can also mean that the part or sensor is doing exactly what it should do in reality.
