Byd car fault codes pol22 and po222

Sidi P0222 is caused by low voltage of throttle position sensor circuit B, and pol22 is caused by fuel or [/k0/] gas. There are the following solutions:

1. There are two sensors A and B on the accelerator pedal. If it is too low, directly replace two sensors (one). There is a throttle position sensor opposite the throttle cable. Unplug the plug and measure with a multimeter. It is recommended to go to the 4s shop for inspection and maintenance as soon as possible.

2. The throttle position sensor is also called throttle opening sensor or throttle switch. Its main function is to detect whether the engine is in idle or load state, acceleration or deceleration state.
