Parts for your 2017 Ford Ranger-Throttle position sensors

2017 Ford Ranger Throttle Position Sensors

Based on Ford Workshop Manual (AU/NZ) Section 303-14: Electronic Engine Controls, the 2017 PX MkII Ranger does use throttle position sensing. The system employs dual-track sensors in the accelerator pedal (APP) and a position sensor on the intake throttle valve for the diesel variants (2.2 and 3.2 TDCi), or an electronic throttle body for petrol models in some markets. Bosch EDC17 engine management used on the TDCi engines also specifies an intake throttle with position feedback. So, throttle-position-sensors are absolutely relevant to this model.

On a 2017 Ford Ranger, throttle position sensors tell the engine computer exactly how much “throttle” is being asked for, and confirm where the throttle plate or intake throttle valve actually is. In the diesels, the vehicle doesn’t use a traditional air throttle to set engine speed, fuel controls that. But there is still an electronically controlled intake throttle used to manage EGR flow, smooth shutdown, and improve emissions. That unit includes a position sensor. Meanwhile, the accelerator pedal carries two independent position tracks to give the PCM a clean, redundant signal from the driver’s right foot.

When these sensors disagree or go out of range, the ute can drop into limp mode, show a wrench/check engine light, surge, idle roughly, or have a dead spot on take-off. Common fault codes include P0120–P0124 (throttle/pedal circuit), P2135 (correlation), and actuator codes like P2112. Because the PCM constantly cross-checks signals, it won’t tolerate dodgy data for long.

There isn’t a scheduled service item for throttle position sensors, but a few habits keep them sweet. Avoid blasting the engine bay with a pressure washer, moisture in the connectors under the bonnet can cause intermittent faults. Inspect the wiring looms around the intake throttle/EGR area for chafe. If replacing parts, note that the diesel intake throttle’s motor and sensor are usually supplied as a single assembly, and the accelerator pedal sensor is integrated into the pedal module. Don’t try to “adjust” a TPS—there’s nothing to set. After replacement, use a scan tool to clear codes and run throttle/pedal relearn (Ford IDS/FDRS or a capable aftermarket tool). The PCM will often self-learn after a battery-off cycle, but a guided procedure is quicker and more reliable. Choose quality parts that match the original calibration to keep the Ranger responsive and compliant with emissions expectations.

• Keep connectors clean and dry, use dielectric grease sparingly on seals.
• Do not force the throttle plate/valve by hand.
• If you see related DTCs or limp mode, diagnose before replacing—often it’s a wiring or connector issue.

Does a 2017 Ford Ranger actually have a throttle position sensor?

Yes. The accelerator pedal uses dual position sensors, and the diesel intake throttle valve (or petrol electronic throttle body) has an internal position sensor. They’re core to the Ranger’s drive-by-wire system.

Where is the TPS on a 2017 Ranger diesel?

The throttle position feedback is built into the intake throttle valve assembly on the inlet tract near the EGR plumbing. The accelerator pedal module under the dash also houses two position sensors.

Do I need to calibrate anything after replacing the pedal or intake throttle?

It’s best practice to perform a throttle/pedal relearn with a compatible scan tool after replacement. The PCM can adapt over a short drive, but a guided procedure helps avoid repeat faults and ensures crisp throttle response.
