Parts for your 2010 Ford Falcon-Throttle position sensors

2010 Ford Falcon throttle position sensor (TPS): what it does and how to look after it

Relevant technical sources confirm the 2010 Ford Falcon (FG series) absolutely does use a throttle position sensor. It’s built into the electronic throttle body and read by the powertrain control module. References: Ford FG Falcon Workshop Manual (2008–2014), Section 303-14A “Fuel Charging and Controls – Electronic Throttle Control”, Ford FG Falcon wiring diagrams (ETC/PCM), and the factory DTC list covering TPS/ETC faults such as P0121–P0123 and P2135. These documents describe dual, redundant throttle position signals (TPS1/TPS2) inside the throttle body on FG models.

On the 2010 Falcon, the TPS’s job is to tell the PCM exactly how far the throttle blade is open. Because this Falcon runs drive‑by‑wire, the throttle body houses an electric motor and two position sensors that constantly cross‑check each other. That data is used to control fuelling, spark, idle speed, cruise control and traction/ESP behaviour. If either sensor disagrees with the other, the PCM throws a code and can drop the car into limp mode to keep everyone safe.

As part of routine servicing, the TPS itself isn’t a separate, serviceable item on most FG Falcons, it’s integrated with the throttle body. Practical maintenance focuses on keeping the throttle body clean and ensuring the wiring and connectors are in top nick. Under the bonnet, look for any loose plugs, rubbed wiring, or oil vapour gunk at the throttle body. A careful clean of the throttle bore with throttle‑body‑safe cleaner can smooth idle and pedal response—just don’t force the blade open by hand.

If the car logs TPS/ETC codes, surges at idle, hesitates on tip‑in, or drops into limp mode, it’s time for proper diagnosis. A scan tool that shows live data for TPS1/TPS2, APP (accelerator pedal position) and commanded throttle angle is the go, mismatches point to wiring faults, throttle body wear, or pedal sensor issues. When replacement is needed, most workshops fit a complete throttle body assembly with a new gasket, then carry out an idle/throttle relearn with a scan tool (or a key‑on/key‑off and idle procedure per the workshop manual). Torque the bolts evenly, clear codes, and take it for a gentle drive so the PCM can finish adapting. That approach keeps the Barra running sweet and ready for more kilometres.

• Typical symptoms of TPS/ETC faults: intermittent limp mode, unstable idle, poor fuel economy, hesitation on acceleration.
• Common related DTCs on FG: P0121–P0123, P0221–P0223, P2106, P2110, P2135.

FAQ

Does a 2010 Ford Falcon have a separate TPS or is it part of the throttle body?
The 2010 FG Falcon uses electronic throttle control, and the throttle position sensing is built into the throttle body. It’s a dual‑sensor setup that’s not typically replaced on its own, most fixes involve swapping the complete throttle body assembly.

What are the signs the TPS on an FG Falcon is playing up?
Owners usually notice a rough or hunting idle, flat spots on light throttle, cruise control dropping out, or limp mode with warning lights. Scan tools commonly show codes like P0121–P0123 or P2135, which indicate issues with the dual TPS signals disagreeing.

Do I need to do a relearn after cleaning or replacing the throttle body?
Yes. After cleaning or replacing the assembly, a throttle/idle relearn helps the PCM recalibrate. Many workshops use a scan tool to initiate it. Without a tool, a key‑on, key‑off and stable idle procedure per the workshop manual can often do the trick before a gentle road test.
