Parts for your 2014 Toyota Crown-Crank angle sensor

2014 Toyota Crown crank angle sensor — what’s fitted and how to look after it

Based on Toyota service literature for the S210-series Crown (engine control chapter), the Toyota Electronic Parts Catalogue for the 4GR-FSE, 2GR-FSE and 2AR-FSE engines, and standard OBD-II diagnostics (DTCs P0335–P0339 for crankshaft position sensing), the 2014 Toyota Crown is fitted with a crank angle sensor (also called a crankshaft position sensor). It’s a core input the ECU uses for spark, fuel, VVT and misfire monitoring, and it’s equally critical on the Crown Hybrid because the petrol engine still needs precise sync when starting and blending with the electric drive.

On the 2014 Crown, the crank angle sensor reads a toothed reluctor on the crankshaft to tell the ECU exactly where the crank is and how fast it’s spinning. That timing data is what lets the ECU fire injectors and coils at the right moment, control variable valve timing, and detect any misfires. Lose that signal and the Crown may crank without starting, stall, or throw a fault light and go into limp mode.

It’s not a routine replacement item, but a bit of preventative care goes a long way. During regular servicing, it’s smart to:

• Scan for stored or pending codes like P0335, even if the dash is clear.
• Visually check the sensor connector and harness for oil wicking, corrosion or chafing under the bonnet.
• Look for oil leaks at the front cover that could contaminate the sensor or its O-ring.
• On a scan tool, confirm a steady cranking RPM and no sync loss, an intermittent drop-out hints at a failing sensor or wiring.

When replacement is needed, they’ll want a quality OEM-spec sensor. Cheapies can cause weak or noisy signals. Fit a new O-ring if applicable, seat the sensor fully, and torque the retaining bolt to spec. Most Toyota sensors are non-adjustable for gap, so correct seating is everything. After refitting, clear codes and perform a road test, some ECUs may refine idle and fuelling once stable sync is restored.

Common signs the Crown’s crank angle sensor needs attention include:

• Hard starting, no start, or stalling when hot
• Rough idle or uneven acceleration
• Fuel use creeping up and power feeling a bit flat
• Check engine light with P0335–P0339

Safety tip: on Hybrid models, never work near rotating components with the vehicle in READY. Keep the key away and ensure the engine can’t start itself.

Popular questions

Does the 2014 Toyota Crown have a crank angle sensor?
Yes. Toyota’s S210 Crown range (V6 and Hybrid) uses a crank angle/position sensor as a primary ECU input for ignition, injection, variable valve timing and misfire detection. It’s a must-have for reliable starting and smooth running.

What symptoms point to a bad crank angle sensor on a 2014 Crown?
Owners often notice hard starting or random stalling, especially once hot. The check engine light may appear with codes like P0335. A scan tool might show erratic or zero RPM during cranking, and the engine can feel flat or surgey under load.

Is the crank angle sensor a regular service item on the Crown?
No, it’s not replaced on a schedule. However, it’s worth inspecting the wiring and connector during routine services and checking for oil leaks nearby. Replace the sensor if there are fault codes, signal drop-outs, or confirmed internal failure.
