P0222 code definition

Throttle/Pedal Position Switch/Sensor B Circuit Low Input

What the P0222 code means

The manufacturer specifies a range of acceptable voltage to be produced from the throttle position sensor. The P0222 code is an indication that the voltage produced by the throttle position sensor has been the detected by the Engine Control Module (ECM) to have fallen below this specification.

What are the causes of the P0222 code?

  • Faulty throttle position sensor
  • Faulty ECM
  • Malfunction within the throttle body
  • Throttle position sensor that is out of alignment
  • Unplugged or damaged wiring associated with the throttle position sensor.

What are the symptoms of the P0222 code?

  • Poor acceleration
  • Loss of power
  • Engine may be hard to start or not start at all
  • Accelerator pedal may be unresponsive
  • The Check Engine Light will be illuminated

How does a mechanic diagnose the P0222 code?

A mechanic may diagnose the P0222 code by visually inspecting the throttle body and everything associated 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 include making sure all electrical connectors are plugged in and properly secured. If everything associated with the throttle body passes the visual inspection, 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 throttle position sensor passes the voltage test, the mechanic would then use a high tech scan tool to test the ECM for faults, as it is one of the last parts unchecked in this system.

Common mistakes when diagnosing the P0222 code

Assuming that the throttle position sensor is faulty because this part is mentioned in the trouble code definition.

This is one of the worst mistakes that someone can make when attempting to diagnose a Check Engine Light. Just because a part is mentioned in a trouble code definition does not mean that the part is faulty. In fact, it could mean that the part or sensor is doing exactly what it is intended to do.

How serious is the P0222 code?

The P0222 code is serious as it can cause driveability issues. It can become quite bothersome to a vehicle owner to experience a lack of power while driving their vehicle and running late to work. This type of symptom usually convinces the driver to repair the issue as soon as possible.

What repairs can fix the P0222 code?

Additional comments regarding the P0222 code?

When this code appears it will not cause intermittent symptoms. This code will cause the symptoms listed the entire time the code is stored. The problems associated with this issue will not be resolved until it is diagnosed and repaired.
