Code P0122 Mazda Description
Idle position of the throttle valve is determined by the ECM receiving the signal from the throttle position sensor. This sensor controls engine operation such as fuel cut. On the other hand, the Wide open and closed throttle position switch, which is built into the throttle position sensor unit, is not used for engine control.
What are the Possible Causes of the DTC P0122 Mazda?
- Faulty throttle position sensor.
- Throttle position sensor harness is open or shorted
- Throttle position sensor circuit poor electrical connection
