Parts for your 2007 Toyota Crown-Throttle position sensors

2007 Toyota Crown throttle position sensor (TPS) — fitment, purpose and servicing

Is a throttle position sensor relevant on the 2007 Toyota Crown? Yes. Toyota’s own technical literature for the S180-series Crown (2003–2008) fitted with GR-series petrol engines (4GR‑FSE 2.5L, 3GR‑FSE 3.0L, 2GR‑FSE 3.5L) specifies Electronic Throttle Control (ETCS‑i). In these systems a dual‑track throttle position sensor is built into the throttle body alongside the throttle actuator motor. The sensor isn’t adjustable and is generally not serviced separately from the throttle body. This design and diagnostic coverage (e.g., DTCs P0120–P0123/P0220 range) are documented across Toyota Repair Manual/TIS and New Car Features publications for the GR‑FSE family, which underpins the 2007 Crown.

The 2007 Toyota Crown absolutely runs a TPS, and it does a fair bit of heavy lifting. In simple terms, this sensor tells the engine computer exactly where the throttle plate sits, so fuel, spark and idle control stay on point. Because the Crown uses Toyota’s ETCS‑i drive‑by‑wire setup, the TPS lives inside the throttle body with the motor. It works in tandem with the accelerator pedal position sensor to keep things smooth and safe, with redundancy to catch faults before they turn ugly.

It isn’t a routine service item like filters or plugs, but it does benefit from a bit of love. Every 40–60,000 kilometres (or if the idle gets a bit lumpy), a careful throttle body clean can sharpen response and prevent sticky operation that confuses the TPS. Use a proper throttle‑body cleaner, avoid forcing the butterfly by hand, and keep solvent away from electronics. After any clean or throttle body replacement, a throttle learn/idle relearn with a scan tool is a smart move.

Common clues the TPS/throttle body needs attention include a hunting idle, hesitation, sudden limp mode, or the MIL lighting up with codes like P0120–P0123 or P0220‑type faults. Before swapping parts, check for intake leaks, manky throttle deposits, poor grounds and brittle connectors — they’re frequent culprits. If the sensor itself has failed, note that on these Crowns the TPS isn’t usually sold separately, the fix is a complete throttle body assembly. Go genuine or a trusted OEM supplier, and always reseal the gasket, clear codes and perform the learn procedure. A quick battery disconnect isn’t a substitute for proper calibration.

Look after the throttle body and its sensor, and the Crown will keep that silky GR‑engine feel — smooth idle, crisp take‑off and tidy fuel economy — just the way it left the factory.

Popular questions about 2007 Toyota Crown TPS

Does the 2007 Toyota Crown use both a pedal sensor and a TPS?
Yes. The accelerator pedal position sensor tells the ECU what the driver wants, and the TPS inside the throttle body tells it what the throttle plate is actually doing. The ECU compares both for accuracy and fail‑safe operation.

Can the TPS be replaced on its own on a 2007 Crown?
Typically no. On ETCS‑i Crowns the TPS is integrated into the throttle body and isn’t serviceable separately. If the sensor track fails or goes out of range, the remedy is usually a complete throttle body replacement followed by a throttle/idle relearn.

What are the signs of a dodgy TPS on a 2007 Crown?
Erratic idle, flat spots on light throttle, sudden limp mode, poor fuel economy, or a check‑engine lamp. Scan for codes like P0120–P0123 or P0220‑series, inspect wiring and grounds, clean the throttle body, then re‑test before committing to a new unit.
