Throttle/Petal Position Sensor/Switch ‘B’ Circuit Low Input


Table of contents

P0222 Possible Causes

  • Faulty Throttle position sensor
  • Throttle position sensor harness is open or shorted
  • Throttle position sensor poor electrical connection

How do I fix code P0222?

  Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.

Cost of diagnosing the P0222 code

  The cost of diagnosing the P0222 code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.

When is the code detected

  An excessively low voltage from the Throttle Position Sensor (TPS) is sent to Engine Control Module (ECM).

Possible Symptoms

  • Engine Light ON (or Service Engine Soon Warning Light)
  • No throttle response

P0222 Description

  Electric Throttle Control Actuator consists of throttle control motor, throttle position sensor (TPS), etc. The throttle position sensor responds to the throttle valve movement.
The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the Engine Control Module (ECM) In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.
