2017 Ford Escape crank-angle-sensor: what it does and when to replace it

Yes, the 2017 Ford Escape is fitted with a crank-angle-sensor (more commonly called a crankshaft position sensor or CKP). Technical references that specify its presence include: Ford Workshop Manual for the 2017 Escape/Kuga (Engine — Electronic Engine Controls sections 303-14), Ford wiring diagrams identifying the CKP circuit (engine management inputs), and OEM parts catalogues that list a dedicated crankshaft position sensor for the 1.5L EcoBoost, 2.0L EcoBoost and 2.5L iVCT engines. Independent databases such as Autodata and ALLDATA also show diagnostic procedures and fault codes (e.g., P0335–P0339) for the CKP on this model, confirming the sensor is integral to engine control.

On the 2017 Escape, the crank-angle-sensor monitors the crankshaft’s exact position and speed, feeding that info to the ECU so it can time fuel injection and spark bang-on. Without a clean signal, the engine can be hard to start, misfire, stall at idle or while cruising, and throw the check engine light. Fuel economy and driveability can go out the window when the signal gets noisy or drops out.

This isn’t a routine “every X kilometres” replacement item, but it is worth checking during servicing if there are symptoms or fault codes. If the Escape shows intermittent no-starts when hot, random stalling at lights, long cranks, or sets CKP-related codes, testing the sensor and its wiring is the go. A quick visual under the bonnet to make sure the connector is snug, pins aren’t corroded, and the harness isn’t chafed near the crank pulley or transmission bellhousing can save headaches.

When replacement is needed, a quality OE-spec sensor is recommended. The job typically involves disconnecting the battery, safely lifting the vehicle if access is from underneath, unplugging the CKP connector, removing the retaining bolt, swapping the sensor, and refitting to the correct depth. Always follow workshop manual guidance for torque specs and routing the loom away from hot or rotating parts. After refit, clear codes and perform a crank relearn if the scan tool or manual calls for it—this helps the ECU sync quickly and keeps the idle behaviour tidy.

• Common signs it’s on the way out: hard starting (especially warm), random stalling, misfires, drop in power, and the MIL on.
• Prevention tips: keep oil leaks off the sensor area, ensure good battery/earths, and fix any damaged loom clips so the CKP wiring doesn’t rub through.

Popular questions

Where is the crank-angle-sensor on a 2017 Ford Escape?
The CKP is typically mounted low on the engine facing the crankshaft reluctor wheel—on these Escapes it’s usually near the crank pulley or at the transmission bellhousing area. Access can be from underneath with the splash shield removed. A torch and mirror help spot the single retaining bolt and the plug.

What symptoms point to a failing CKP on this model?
Owners often report long crank times, occasional no-start when hot, sudden stalling at idle or while coasting, rough running, and the check engine light. Scan tools may show P0335–P0339. Because similar symptoms can come from cam sensors or fuel issues, a proper diagnostic with live data is best.

Does the CKP need regular replacement?
No set interval. It’s replaced on condition—when tests show a weak or missing signal, or when wiring/connector damage is found. Using a quality replacement and ensuring the harness is clipped correctly helps it last for the long haul.
