What is the P0222 Fault code? What does it all mean?
There are two types sensors that measure the distance of the throttle plate being opened on vehicles with electronic throttle controls (ETC). These sensors are the Throttle Position Sensor/Switch, and the Throttle Position Sensor.
The throttle position sensor sends regular voltage signals to powertrain control module (PCM). The speed of the vehicle, as well as the current position of this sensor, affects the level of the voltage signals. The sensor is rotated by pressing the accelerator pedal. The voltage signal informs the PCM how open the throttle.
The PCM uses data from throttle position sensors to adjust the amount and timing of spark plug ignitions. These data indirectly influence the performance and emission control of the exhaust system.
The PCM periodically checks the voltage signal to ensure that the throttle position sensor works properly. It also compares it with the parameters stored in its memory. The PCM will assign fault code P0222 to any sensor whose voltage is lower than the recommended level. This code is set for most applications if the voltage level from the sensor drops below 10%. The code’s “B” label refers to a particular circuit or sensor. Check your vehicle’s service manual to determine which circuit is the “B”.
What causes the P0222 Fault code?
Here are some reasons why P0222 should be set.
- – Defective throttle sensor/switch
- – A defective accelerator pedal position sensor/switch
- – Sensors with damaged, burned, or broken wires, or loose, rusty connections
- – Short circuit problems in wiring or connectors to sensors
- – The throttle plate is not moving because of carbon deposits in the throttle body
- – Wearing, defective throttle body
- – A misaligned throttle position sensor or accelerator pedal
- – Defective PCM (rarely)
What are the symptoms for P0222 Malfunction Codes?
These symptoms may be present if you own a vehicle that has the code “P0222”.
- – Illumination for the check engine light
- – Acceleration slowed down and engine shaking
- – Low engine performance
- – Engine stalling
- – The engine may not start, but the starter may be able to get it started
- – The engine could run hard
- – The accelerator pedal might not respond
- – Idle engine speed fluctuations
How to Fix the P0222 Fault Code
The following repairs may be able to resolve the P0222 fault code:
- – Replacing your throttle position sensor
- – Replacing the accelerator pedal position sensor
- – Replacing your throttle body
- – Repair or replacement wiring for the throttle electrical system
- – Repair of damaged wires, connectors for throttle / pedal position sensor
- – Adjusting the throttle position sensor and accelerator pedal position sensor to the correct positions
- – Reprogramming or replacing the PCM
In general, the voltage signal should not be below zero when the throttle is closed.
Regular maintenance is a smart idea. Regular maintenance will prevent cable and connector damage, and help you to detect problems early.
How serious is the P0222 Fault code?
Fault code P0222 can cause serious driving problems. It can cause problems such as a lack of power, misfires, and stalling. These symptoms can also pose a danger to driving safety. The fault must be fixed quickly.
