Parts for your 2010 Toyota Wish-Crank angle sensor

2010 Toyota Wish crank angle sensor

Based on Toyota’s technical documentation for the ZGE20/21/25 series and the 2ZR/3ZR engine family, the 2010 Toyota Wish is fitted with a crankshaft position sensor (often called a crank angle sensor). Toyota’s workshop manual (Engine Control – SFI), the Electrical Wiring Diagram (EWD), and the Toyota Electronic Parts Catalogue for ZR engines all list a dedicated crankshaft position sensor used by the ECU for timing and engine speed input. So yes—this model uses a crank angle sensor.

The crank angle sensor on a 2010 Toyota Wish is the quiet achiever that lets the ECU know exactly where the crank is and how fast it’s spinning. Paired with the cam sensor, it helps the ECU fire the injectors and coils at the right moment, keeping the 2ZR or 3ZR engine smooth, efficient and within emissions targets. When it goes off, owners might see a check engine light, hard starting, stalling at idle, or sudden loss of power. Fault codes commonly include P0335 or P0339.

As part of routine servicing, it’s worth giving the sensor and its connector a quick once-over—look for oil contamination, corrosion in the plug, or a frayed harness near the front of the engine block. The sensor isn’t a consumable with a set replacement interval, but high kilometres, heat, and oil leaks can shorten its life. If the engine’s been weeping oil, sort the leak and clean the area so grime doesn’t build up around the sensor tip.

Replacement is straightforward for a competent DIYer, though most owners will prefer a workshop. Typical steps include disconnecting the battery negative, unplugging the sensor, removing the retaining bolt, and easing the sensor out. Fit a quality OEM-equivalent sensor, lightly lube the O-ring if specified, and torque the bolt to spec. There’s no coding on these ZR engines, the ECU will read the new sensor straight away. If the check engine light was on, clear codes and road-test to confirm stable RPM and clean starts.

Good practice tips:

• Use genuine or reputable OE-brand sensors to avoid intermittent faults.
• Inspect the reluctor wheel through the sensor port if there’s metal debris on the old sensor.
• Check harness routing so it won’t chafe on brackets or the drive belt.

Keeping the crank angle sensor healthy means better starting, nicer throttle response, and fewer headaches on long Kiwi and Aussie road trips.

Popular questions

Where is the crank angle sensor on a 2010 Toyota Wish?
The sensor is mounted to the engine block facing the crankshaft reluctor wheel, typically on the gearbox side of the block on ZR engines. It reads the toothed wheel on the crank to provide position and speed data to the ECU.

What are common symptoms of a failing crank angle sensor?
Owners might notice long cranking, random stalling, a check engine light, poor fuel economy, or the engine cutting out when hot. Scan tools often show codes like P0335/P0339 and erratic RPM signals.

Does a new crank angle sensor need programming?
No. On the 2ZR/3ZR engines used in the 2010 Wish, the ECU automatically recognises the new sensor. After installation, clear any stored codes and perform a short road test to verify normal operation.
