Parts for your 2017 Toyota Wish-Crank angle sensor

2017 Toyota Wish crank angle sensor: what it does and when to sort it

Yes, the 2017 Toyota Wish is fitted with a crank angle sensor (Toyota generally calls it the Crankshaft Position Sensor, “NE” signal). Technical references that confirm this include the Toyota ZGE20/25 Series Repair Manual for the SFI system (which lists diagnostics like DTC P0335/P0339 for the crankshaft position sensor circuit) and the Toyota New Car Features (NCF) manuals for the 2ZR-FAE/3ZR-FAE engines that detail the ECM’s use of the NE signal together with the camshaft signal(s) for precise ignition and injection timing. In short, it’s absolutely relevant on a 2017 Wish.

On the 2ZR-FAE/3ZR-FAE engines used in the Wish, the crank angle sensor reads a toothed wheel on the crankshaft and feeds the engine control module (ECM) the exact crank position and engine speed. That lets the ECM fire the injectors and spark at the right moments, keeps idle stable, and makes starting clean and quick. If the signal drops out, the engine may crank forever without firing, stall randomly, or light the check engine lamp with codes like P0335.

There’s no routine replacement interval for the crank angle sensor—it’s a solid-state item and typically lasts the life of the engine. As part of regular servicing, it’s smart to:

• Scan for fault codes if there’s a hard start, misfire, or sudden stall.
• Inspect the sensor connector and harness for oil intrusion, heat damage, or a loose fit.
• Check nearby oil leaks—fixing rocker cover or front seal weeps helps keep the sensor clean and dry.
• Avoid metal debris build-up around the reluctor ring area during other engine work.

When replacement is needed, use a reputable OE-equivalent sensor. Disconnect the battery, let the engine cool, and take care with the O-ring so it seals first go. The mounting bolt should be snugged to spec (workshop manual value) so the sensor sits flush. After fitting, clear any stored codes and road test, no special programming is usually required on these Toyotas, and the ECM will read the new sensor straight away.

Typical symptoms pointing to the crank angle sensor on a 2017 Wish include:

• Long crank or no-start when hot or cold
• Intermittent stalling and a dead tachometer drop
• Check engine light with P0335/P0339

Sorted promptly, a fresh sensor gets the Wish back to smooth running without dramas.

Where is the crank angle sensor on a 2017 Toyota Wish?

On the ZR-series engines, it’s mounted on the engine block reading the crankshaft reluctor wheel. Access is from the side of the block, depending on tools and setup, removing the right-front wheel and inner guard liner can make access easier. Always identify the sensor by its single retaining bolt and two/three-pin connector.

What are the common signs it’s failing?

Hard starting, an occasional no-start, sudden stalling at idle or while cruising, and the check engine lamp with codes like P0335/P0339. The tacho may briefly drop to zero during a stumble. If those sound familiar, a scan and live data check of the NE signal is a good next step.

Does a new crank angle sensor need programming?

On the 2017 Wish, no special coding is typically required. Fit the sensor, ensure the connector is clean and locked, clear any codes, and road test. If issues persist, check wiring integrity and related timing signals.
