Parts for your 2010 Toyota Crown-Camshaft sensor

2010 Toyota Crown camshaft sensor — purpose, fitment and service tips

Yes, the 2010 Toyota Crown is fitted with camshaft position sensors. Toyota’s factory repair information for the S200-series Crown (GRS200/201, including 4GR‑FSE, 3GR‑FSE and 2GR‑FSE engines) lists “Camshaft Position Sensor (Bank 1/Bank 2)” as key ECM inputs, with related diagnostics P0340/P0341/P0345/P0346. The Toyota Electronic Parts Catalogue for these engines also lists a “Sensor, Cam Position” per cylinder bank. These technical sources confirm the camshaft sensor is relevant and used on this vehicle.

On a 2010 Toyota Crown, the camshaft sensor keeps the engine timing sharp as. It tells the ECU exactly where each cam is in its rotation, so the car can run sequential fuel injection, fire the coils at the right moment, and dial in VVT‑i for punchy torque and tidy fuel economy. Without a clean signal, cold starts get cranky, idle can go lumpy, and the dash may light up with a check-engine lamp.

It’s not a scheduled replacement item, but it does pay to keep an eye on it during regular servicing. Owners can watch for tell-tales like hard starting, intermittent stalling, sluggish performance, poor economy, or codes such as P0340/P0345. On the GR V6 there are two sensors (one per bank), mounted near the front of each cylinder head by the timing cover, so correct bank identification matters.

If replacement is needed, a careful, by‑the‑book approach keeps things sweet:

• Disconnect the negative battery terminal and let the car sit a minute.
• Unplug the sensor connector, remove the hold-down bolt, and twist the sensor out.
• Inspect and replace the O‑ring, lightly oil it before refitting to avoid nicks.
• Install and torque to the factory spec from the Toyota repair manual, reconnect, clear any DTCs and confirm live data is stable.

Good oil is the quiet hero here. Regular oil and filter changes help VVT‑i actuators and keep sensor targets clean, reducing signal noise. If the sensor fault is intermittent, check loom routing and connector pins for corrosion or oil wicking before throwing parts at it. For most Crowns, access is decent and labour is typically under an hour per bank with basic hand tools. After replacement, a short road test and a quick scan for pending codes will confirm the Crown’s back to silky operation.

• Where is the camshaft sensor on a 2010 Toyota Crown?
  On GR-series V6 models there’s one sensor per bank, mounted at the front of each cylinder head beside the timing cover. From the top of the engine bay, look down near the cam cover—small, single-bolt sensors with a two- or three-pin connector.
• What fault codes point to a bad camshaft sensor?
  Common codes are P0340/P0341 for Bank 1 and P0345/P0346 for Bank 2. They indicate circuit or performance issues. Always check wiring, connectors and oil contamination before replacing the sensor.
• Is it safe to drive with a failing camshaft sensor?
  The car may run, but starting can be tough and it may lose power or stall. It’s best to sort it promptly to avoid being stranded and to protect the catalytic converters from misfire.
