P0222 Throttle/Pedal Position Sensor/Switch B Circuit Low Input

Technical Description

Throttle Position Sensor/Switch B Circuit Low Input

What does that mean?

This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model.

A P0222 code means that the the car’s computer has detected that the TPS (throttle position sensor) is reporting too low a voltage. On some vehicles that lower limit is 0.17 – 0.20 volts (V). The B refers to a particular circuit, sensor, or area of a particular circuit.

Did you adjust it when you installed it? If the signal value is less than .17V then the PCM sets this code. Could be an open or a short to ground in the signal circuit. Or you may have lost the 5 Volt reference voltage.

Symptoms

  • Rough or low idle
  • Stalling
  • Surging
  • No/little acceleration
  • other symptoms may also be present

    • Causes

    A code P0222 may mean that one or more of the following has happened:

  • TPS not mounted securely
  • TPS circuit short to ground or another wire
  • Faulty TPS
  • Damaged computer (PCM)

    • Possible Solutions

    Some recommended troubleshooting and repair steps are:

  • Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary
  • Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary.
  • If recently replaced the TPS may need to be adjusted. On some vehicles the installation instructions call for the TPS to be properly aligned or adjusted, consult a repair manual for specifics.
  • If there are no symptoms at all, the problem may be intermittent and clearing the code may resolve the issue temporarily. If this is the case then you should definitely check the wiring to be sure it’s not rubbing on anything, grounding, etc. The code may come back.

    "Delete Error Code Permanently, Disable DTC Error Code Function for p0222 in the ECU"

    In extreme cases, we even have the option to permanently remove the specific DTC p0222 and disable the function of the specific error code in the ECU. All other fault code functions will then continue to work to protect the engine. This is different from clearing an error code with a diagnostic device. We have the option to permanently remove the function of the specific error code, so that it never comes back. Also emergency running that occurs on the specific error code can be solved in most cases.

    Of course we prefer to first try to solve the cause of the error code, but sometimes the only solution is to permanently disable the DTC function of p0222.
