Parts for your 2010 Toyota Crown-Crank angle sensor

2010 Toyota Crown crank-angle sensor: purpose, servicing and tips

Based on Toyota technical literature for the S200-series Crown (model years 2008–2012), including the engine control system descriptions and EWDs on Toyota’s service information (TIS), every 2010 Toyota Crown fitted with GR-series engines (4GR-FSE 2.5L, 3GR-FSE 3.0L, 2GR-FSE 3.5L, and the hybrid’s 2GR-FXE) uses a crankshaft position sensor—commonly called a crank-angle sensor. In these documents the sensor provides the NE signal to the engine control module and works with the camshaft position sensors for precise ignition and injection timing. Toyota parts catalogues for the 2010 Crown also list a dedicated crankshaft position sensor, confirming it’s fitted to this vehicle.

On the 2010 Toyota Crown, the crank-angle sensor is the timekeeper for the whole show. It reads the crank’s rotation and position, sending a clean timing pulse (NE) to the ECM so the engine knows exactly when to fire the plugs and inject fuel. Teaming up with the cam sensors, it enables fast starts, smooth idle, solid power, and proper knock control. If it drops out, the ECM can’t trust engine speed or position, so you’ll often get hard starting, stalling, or a complete no-start.

It’s a solid-state, maintenance-free part, so there’s no fixed replacement interval. As part of regular servicing, it’s smart to give the area a once-over: check the harness routing under the bonnet, ensure the connector is clean and latched, and look for oil seeping onto the sensor body or wiring. On GR engines it’s typically mounted low on the block near the transmission bellhousing, so access is usually from underneath—drop the undertray, mind the hot exhaust, and don’t pull on the loom.

Common clues it’s on the way out include a long crank, intermittent stall at lights, erratic tacho, and fault codes like P0335 (Crankshaft Position Sensor “A” Circuit) or P0336 (Range/Performance). If those pop up, rule out basics first: battery health, connector corrosion, damaged wiring, or metal debris stuck to the sensor tip. When replacing, choose an OEM-quality sensor, lightly oil the O-ring, seat it squarely, and tighten the retaining bolt to the factory spec—no gorilla grip needed. A relearn isn’t typically required on Toyotas, once fitted, clear codes and road test. Most workshops will have it sorted in under an hour, and it’s a tidy bit of preventative peace of mind if the old one’s playing up.

• Typical symptoms: hard start, stall, rough running, P0335/P0336 DTCs
• Service tip: inspect connector and loom routing each service, especially after other engine work
• Location: low on the engine block by the bellhousing, access from under the car

Popular questions about the 2010 Toyota Crown crank-angle sensor

Where is the crank-angle sensor on a 2010 Toyota Crown?
It’s mounted low on the engine block near the transmission bellhousing on GR-series engines. Access is usually via the underside with the engine undertray removed. Take care around the exhaust and ensure the connector is clean and firmly latched when refitting.

What fault codes point to a bad crank-angle sensor?
The big ones are P0335 (crankshaft position sensor circuit) and P0336 (range/performance). You may also see cam sensor correlation codes if the ECM loses sync. Always check the wiring and connector before condemning the sensor, as heat and oil exposure can mimic sensor failure.

Does the crank-angle sensor need routine replacement?
No, it’s maintenance-free and replaced on condition. During regular servicing, inspect for damaged wiring, oil contamination, or loose connectors. If symptoms or DTCs arise, fit an OEM-quality part, replace the O-ring, and clear codes. Most replacements are straightforward and quick.
