Parts for your 2015 Ford Falcon-Throttle position sensors

2015 Ford Falcon throttle position sensors (TPS)

Yes, the 2015 Ford Falcon (FG X) does use throttle position sensors. Factory documentation such as the Ford FG X Falcon Workshop Manual (Electronic Engine Controls, Section 303-14) and Ford wiring diagrams list dual TPS circuits (often labelled TP1/TP2) within the electronic throttle body. Bosch documentation for the electronic throttle unit used on Barra/Coyote applications also details the integrated dual-position feedback. So a TPS is relevant and fitted on the 2015 Falcon, it’s part of the drive-by-wire throttle body and works alongside the accelerator pedal position sensor.

On a 2015 Falcon, the TPS tells the powertrain control module exactly how far the throttle blade is open. The PCM then fine-tunes fuel, spark, idle speed and even gearbox shift behaviour. Because it’s an electronic throttle, the throttle body contains two independent position sensors for redundancy and safety. If their signals don’t agree, the car can drop into limp mode to protect the engine and occupants.

Owners typically won’t “service” the TPS on its own, it’s integrated into the throttle body and not usually sold separately. What is sensible is keeping the throttle body clean and checking the harness. A light clean of the bore and blade with proper throttle-body cleaner every 40,000–60,000 kilometres helps prevent sticky operation that can confuse the sensors. Avoid forcing the blade by hand and don’t drown the electronics—short, controlled bursts on a lint-free cloth does the trick.

• Common symptoms of TPS/throttle body issues: erratic idle, hesitation, surging, poor kickdown, “Reduced engine power” or MIL on.
• Typical fault codes technicians see: P0121–P0124, P0221, P2101, P2110, P2135 (TP correlation).

If replacement is needed, the usual approach is a complete throttle body. After fitting, a throttle/idle learn is recommended. Many scan tools offer an ETC relearn function, otherwise: key ON (engine off) for ~30 seconds, key OFF for ~30 seconds, start and let it idle for 3–5 minutes (A/C off), then a short drive with gentle accel/decel so the PCM adapts. Always tighten fasteners to the manufacturer’s spec in the Ford WSM, check for intake leaks, and verify the gasket or seal is fresh.

During regular servicing, a quick visual on the connector and loom near the throttle body is worthwhile—heat and oil can harden insulation. Keeping the air filter fresh also reduces contamination of the throttle plate and sensors. Genuine-quality parts and up-to-date PCM calibration files help keep the FG X smooth and responsive.

Does the 2015 Falcon have a separate TPS or is it built into the throttle body?

It’s built into the electronic throttle body as dual sensors (TP1/TP2). The car also has a separate accelerator pedal position sensor on the pedal, which the PCM cross-checks with the TPS for safety and accuracy.

Does a new throttle body/TPS need calibration or relearning?

Yes. After replacement or cleaning, the PCM benefits from an ETC/idle relearn. A scan tool can command this, or you can follow a manual learn routine (key-on/idle/drive cycle). This helps stabilise idle and throttle response.

What fault codes point to TPS issues on an FG X?

Codes like P0121–P0124, P0221 and P2135 indicate TP signal range/correlation problems. You may also see P2101 or P2110 when the PCM limits throttle due to a detected mismatch. Proper diagnosis should include wiring checks and live data review of TP1/TP2.
