Parts for your 2006 Ford Escape-Throttle position sensors

2006 Ford Escape throttle-position-sensors (TPS): purpose, servicing and FAQs

Technical sources confirm a throttle-position-sensor is used on the 2006 Ford Escape. The Ford Workshop Manual (Section 303-14, Electronic Engine Controls) specifies a Throttle Position (TP) sensor for the 2.3L and 3.0L cable-operated throttle bodies, and an electronic throttle body with dual TP sensors (TP1/TP2) on the 2006 Escape Hybrid. The Motorcraft service parts catalogue lists a stand-alone TP sensor for the petrol 2.3L/3.0L and a complete throttle body assembly with integral TP sensors for the Hybrid. Diagnostic libraries such as AllData/Mitchell include TP-related DTCs (e.g., P0121–P0123, and P2135 for ETC) for this model year. So yes—TPS is relevant and fitted across the 2006 Escape range.

The throttle-position-sensor (TPS) tells the Escape’s PCM exactly how far the throttle plate is open. That info is used to fine‑tune fuel delivery, ignition timing, transmission shifts and torque control, helping the SUV feel smooth and responsive from a gentle take‑off to a quick overtake on the motorway. On the 2.3L and 3.0L petrol engines, the TPS is a small sensor bolted to the side of the cable-operated throttle body, the Hybrid uses an electronic throttle body with a motor and dual, built‑in TPS tracks for redundancy.

As part of routine servicing, the TPS isn’t a scheduled replacement item, but it’s worth a quick once‑over. Keeping the throttle body clean helps the sensor read consistently—carbon build‑up can make the plate stick and confuse the readings. Inspect the TPS connector and wiring for oil ingress, moisture or chafing, especially on higher‑kilometre vehicles that see dusty roads. If the check engine light pops up with codes like P0121, P0122 or P0123 (or P2135 on ETC/Hybrid), or if there’s hesitation, surging, dodgy kickdown or odd shifting, the TPS or throttle body deserves attention.

Replacement advice is straightforward. On the 2.3L/3.0L cable-throttle, the TPS is held by two screws—use a quality part (Motorcraft is a safe bet), avoid twisting the sensor against the throttle shaft, and snug the screws evenly. Clear codes and perform an idle relearn afterwards (letting it idle with accessories off, then on, or using a scan tool). On the Hybrid (and any Escape with electronic throttle), the TP sensors are integral to the throttle body—replacement is the whole unit, with a throttle/ETC relearn via scan tool. Don’t “adjust” a TPS on these, the PCM handles calibration. A short road test confirming smooth tip‑in and stable idle wraps it up nicely.

• Tip: Check engine and transmission operation together—an erratic TPS can mimic gearbox faults.

FAQs

Where is the TPS on a 2006 Ford Escape?
On the 2.3L and 3.0L petrol models, it’s bolted to the side of the throttle body under the bonnet, opposite the throttle cable lever. On the 2006 Escape Hybrid, the sensor is built into the electronic throttle body, so it isn’t serviced separately.

What are common symptoms of a failing TPS?
Hesitation off the line, flat spots, rough idle, surging cruise, and odd shift timing can all point to TPS issues. The check engine light often tags codes like P0121–P0123, and P2135 on electronic throttle versions. Inspect wiring first, then test or replace as needed.

Does the TPS need periodic calibration?
Not as routine maintenance. The PCM learns idle and throttle angles automatically. Calibration or relearn is needed after replacement or battery/KAM reset—best done with a scan tool on electronic throttle models.
