DTC 14

OPERATION
The throttle position sensor is a variable sensor whose movable contact rotates coaxially with the throttle valve shaft, thus sensing the throttle valve opening.
As the throttle valve shaft rotates, the sensor output Voltage changes. Based on the signal the sensor generates, the engine control unit detects the throttle valve opening and determines the engine operation mode (acceleration or deceleration).

TROUBLESHOOTING HINTS
When short-circuit or wire breakage occurs in the TPS circuit, hesitation, deceleration shock, shift shock in the A/T vehicle, etc. may often be felt.
