Parts for your 2006 Ford Falcon-Throttle position sensors

2006 Ford Falcon throttle position sensors: what they do and how to look after them

Based on Ford’s BA/BF Falcon workshop information for the Barra engines, plus common AU/NZ parts catalogues and Bosch Electronic Throttle Control documentation, a 2006 Ford Falcon (late BA Mk II and BF) absolutely uses throttle position sensors. They’re built into the electronic throttle body as a dual, redundant sensor set that the ECU cross-checks. There isn’t a separate, bolt-on TPS like older cable-throttle setups, if the sensors fail, the throttle body assembly is the service item.

On a 2006 Falcon, the throttle position sensors (TPS) tell the ECU exactly how far the throttle plate is open. Working alongside the accelerator pedal position (APP) sensor, the dual TPS tracks in the electronic throttle body let the ECU manage airflow, idle speed, torque delivery, fuel and spark. That’s why a crook TPS can cause rough idle, flat spots, limp-home behaviour, harsh shifts in autos, or a glowing MIL. Because the Falcon’s system is drive-by-wire, Ford designed it with two TPS signals for safety, if the readings don’t agree, the ECU will step in to protect the engine and driver.

For servicing, treat the TPS as part of the throttle body. Keep the electrical connector clean and dry, check the harness for rub-through, and consider a throttle body clean during scheduled maintenance using throttle-body-safe cleaner. Don’t force the butterfly by hand—use the pedal with the key on if you need to open it for cleaning. After any throttle body replacement or major clean, a throttle relearn/idle learn may be required, most scan tools used in AU/NZ workshops can run the procedure, or it may relearn after a short drive cycle.

• Common symptoms: erratic idle, surging, delayed throttle response, transmission shift flare, MIL with codes such as P0121/P0221/P2135.
• Diagnostics: scan live data for TPS1/TPS2 agreement, wiggle-test the connector, verify 5 V reference and ground, and check for intake leaks before condemning the unit.
• Replacement tips: use a quality throttle body, fit a new gasket or seal if applicable, don’t over-tighten fasteners, clear codes, and perform the relearn.

Technically-minded sources that back this up include Ford’s BA/BF Falcon engine management service literature outlining Electronic Throttle Control with dual TPS inside the throttle body, as well as Bosch ETC design notes describing redundant TPS tracks in drive-by-wire throttles. AU/NZ parts catalogues list the TPS as non-serviceable on BA/BF Falcons, supplied as part of the electronic throttle body.

Does a 2006 Ford Falcon have a throttle position sensor?
Yes. It uses two throttle position sensors integrated into the electronic throttle body. They work with the accelerator pedal sensor to deliver smooth, safe drive-by-wire control. There isn’t a separate external TPS on these models.

Can the TPS be replaced on its own on a 2006 Falcon?
No. On BA Mk II/BF Falcons the TPS is not a separate service part. If diagnosis confirms TPS faults, the correct repair is replacement of the complete electronic throttle body, followed by a throttle/idle relearn and a road test.

What are the signs of a failing TPS on a 2006 Falcon?
Owners may notice erratic idle, hesitation, sudden limp-home, or harsh/late shifts in autos. The check engine light may appear with codes like P0121, P0221 or P2135. Always check wiring and the throttle body for contamination before replacement.
