Parts for your 2017 Ford Escape-Throttle position sensors

2017 Ford Escape throttle position sensor — what it is, and how it’s looked after

Yes, the 2017 Ford Escape (also sold as Kuga) absolutely uses a throttle position sensor. It’s built into the electronic throttle body as two redundant position sensors (often called TP1/TP2) and isn’t typically sold as a standalone part. This setup is documented in Ford’s Workshop Manual for the model year (Electronic Throttle Control, Section 303), Motorcraft diagnostic information listing DTCs such as P0121, P0122, P0123, P0222, P0223, P2135, and common service databases (ALLDATA/Mitchell) that show the integrated sensor circuits and PCM monitoring strategy.

On this Escape, the throttle position sensors tell the PCM exactly how far the throttle plate is open, so the engine gets the right amount of air for smooth idle, decent fuel economy, and proper power on demand. Because they’re integrated into the throttle body, any serious sensor fault usually means replacing the whole throttle body assembly rather than just a tiny sensor.

Signs that the throttle body/TPS assembly is playing up can include rough idle, hesitation, a surging feel at cruise, stalling when coming to a stop, poor fuel use, or a “wrench”/check engine light with the codes above. Sometimes the vehicle will drop into limp mode to protect itself. Before throwing parts at it, a proper scan and live data check (watching TP1/TP2 agreement and percentage) is the go.

As part of routine servicing, it’s smart to:

• Inspect the intake ducting for splits, loose clamps, or vacuum leaks that can mimic TPS faults.
• Clean the throttle bore and plate gently with throttle-body safe cleaner (not harsh carby cleaner) to prevent sticky operation and off-idle stumble.
• Check for relevant software updates, Ford sometimes refines ETC strategies via PCM calibration.

If replacement’s needed, the job typically involves battery negative off, removing the intake pipework, unplugging the connector, unbolting the throttle body, and fitting a new unit with a fresh gasket. Avoid forcing the blade by hand. After installation, perform an idle/ETC relearn: key-on for about a minute without touching the pedal, then start and let it idle, followed by a gentle drive cycle. Many scan tools can run the formal ETC reset as per the Ford Workshop Manual. Because the 2017 Escape also uses an accelerator pedal position (APP) sensor at the pedal, make sure both sides of the system (APP and TP) read sensibly in live data during final checks.

FAQs

Does the 2017 Ford Escape have a separate throttle position sensor I can replace on its own?
No. On this model the TPS is integrated into the electronic throttle body with dual sensors. Ford supplies the throttle body as an assembly. If the TPS circuit fails testing, the reliable fix is to replace the throttle body and carry out an ETC/idle relearn.

What symptoms point to a failing throttle position sensor on a 2017 Escape?
Drivers often notice a rough or high idle, poor off‑the‑mark response, surging at steady speed, stalling when pulling up, or the wrench/check engine light. Scan tools may show DTCs like P0121 or P2135 and disagreement between TP1 and TP2. Always rule out air leaks or a dirty throttle before replacing parts.

Do I need to calibrate or relearn anything after replacing the throttle body?
Yes. After fitting the new unit, perform an ETC/idle relearn. Many scan tools have a throttle/ETC reset function per the Ford Workshop Manual. If you don’t have that, a key-on wait followed by a steady idle and gentle drive cycle usually lets the PCM relearn the new throttle position data.
