DTC P0122: THROTTLE POSITION SENSOR CIRCUIT - LOW VOLTAGE Chevrolet Venture I

Note. For circuit reference, see WIRING DIAGRAMS article.

Circuit Description

Throttle Position (TP) sensor measures amount of throttle opening. PCM uses TP sensor information for fuel delivery calculations. TP sensor readings during acceleration are much higher than those during deceleration or idle. DTC will set if TP sensor signal voltage is less than .16 volt, with ignition on.
