Parts for your 2017 Toyota Crown-Crank angle sensor

2017 Toyota Crown crank-angle sensor: purpose, fitment and servicing advice

Yes, the 2017 Toyota Crown is fitted with a crank-angle sensor (also called a crankshaft position sensor, CKP). Toyota’s S210-series Crown service literature for the 8AR-FTS 2.0L turbo, 2AR-FSE/FXE 2.5L hybrid, and 2GR-FSE 3.5L V6 specifies a CKP sensor used by the engine control module for ignition timing, fuel injection phasing, and misfire monitoring. This is documented across Toyota GSIC/repair manuals, engine control sections, and EWD fault-tree diagnostics that reference DTCs P0335–P0339 for CKP signal issues.

The Crown’s crank-angle sensor is the ECM’s timekeeper. It reads a toothed reluctor wheel on the crank, generating a precise signal that tells the computer exactly where the pistons are in their cycle and how fast the engine’s spinning. With that, the ECM synchronises spark and injector timing, trims fuelling for smooth idle, and protects the engine if something looks off. Even the hybrid variants rely on CKP data to coordinate engine starts and seamless transitions under the bonnet.

Typical signs the CKP may be playing up include:

• Hard starting, intermittent no-start, or sudden stalling when warm
• Rough idle, hesitation, and poor fuel economy
• Stored fault codes such as P0335/P0336 and related CKP/correlation codes
• Tachometer dropouts or erratic RPM readings on scan data

As part of routine servicing, the CKP sensor isn’t a scheduled replacement item. The smart play is preventative: inspect the wiring harness for abrasion near the front or rear of the block (location varies by engine), check the connector for oil ingress or corrosion, and make sure the sensor’s O-ring area isn’t weeping. If replacement is needed, use a quality OEM-equivalent sensor, lightly oil the new O-ring, and refit with the correct bolt torque specified in the Toyota repair manual. Disconnect the battery, keep the connector clean, and avoid prying on the sensor body to prevent damage to the mounting boss.

On most 8AR-FTS engines the sensor is mounted low on the block near the crank pulley, on GR and some AR variants it can be positioned at the transmission side reading the flywheel/drive plate. A quick check in the correct engine section of the Crown’s manual by VIN/engine code will pinpoint the exact spot. After fitting, clear codes and verify clean CKP and cam signals with a scan tool. If correlation codes persist, also check cam sensors and timing chain condition before calling it done.

Popular questions about the 2017 Toyota Crown crank-angle sensor

Does the 2017 Toyota Crown actually have a crank-angle sensor?
It does. Toyota’s S210-series documentation for 8AR-FTS, 2AR-FSE/FXE and 2GR-FSE engines lists a crankshaft position (crank-angle) sensor as a core input for the ECM. It’s essential for start-up, timing, and misfire detection, including on hybrid models.

Where is the crank-angle sensor on a 2017 Crown?
Location varies by engine. The 8AR-FTS typically places it low at the front of the block near the crank pulley, while GR/AR V6 and 2.5 hybrid layouts may mount it at the rear reading the drive plate. Checking the engine code and the Crown’s repair manual will confirm the exact spot under the bonnet.

Can a faulty crank-angle sensor damage the engine?
The sensor itself won’t usually damage the engine, but a failed CKP can cause no-start, stalling, or erratic running. Continued driving with repeated stalls or misfires isn’t ideal. Best practice is to scan for DTCs, confirm power/ground/signal, and replace the sensor if it’s out of spec.
