Throttle Position Sensor
WARNING: This page is about a different variant/trim than selected.
The Throttle Position Sensor (TPS) allows the Powertrain Control Module (PCM) to determine the position and angular rate of change of the throttle blade.
There are two TPS sensors located in the electric throttle. See below for details of the electric throttle.
If a TPS sensor fails, the PCM:
- Adopts a limp home mode where engine speed is limited to a maximum of approximately 2000 rev/min
- Discontinues Evaporative Emissions (EVAP) control
- Discontinues closed loop control of engine idle speed.
With a failed TPS sensor, the engine will suffer from poor running and throttle response.
