Parts for your 2011 Toyota Crown-Camshaft sensor

2011 Toyota Crown camshaft sensor — what it does and when to sort it

Yes, the 2011 Toyota Crown uses camshaft position sensors. Across the S200-series Crowns (GRS200/204 and GWS204), including the 4GR-FSE 2.5L, 3GR-FSE 3.0L, 2GR-FSE 3.5L, and hybrid 2GR-FXE engines, Toyota specifies camshaft position sensors for timing and variable valve timing control. This is documented in Toyota’s Workshop Manual (Engine/Hybrid System – SFI System – Camshaft Position Sensor [Bank 1/Bank 2], DTC P0340/P0345) and the Electrical Wiring Diagram for GRS200/GRS204/GWS204, which shows “G” (cam) and “NE” (crank) signals feeding the ECM. Toyota’s parts catalogue for these engines also lists dedicated camshaft position sensors per bank.

The camshaft sensor on a 2011 Toyota Crown keeps the engine’s timing sharp by telling the ECU exactly where each cam is, so fuel injection and spark happen at the right moment. On these V6 engines with VVT-i, the sensor data also lets the ECU adjust cam phasing for smooth torque, clean emissions and decent fuel economy. If the signal goes missing or out of range, the Crown can become hard to start, run rough, lose power, or drop into limp mode with a check engine light and codes like P0340 or P0345.

It’s not a routine replacement item, but it does pay to give it some love during servicing. Quick wins:

• Keep oil changes on time. Dirty or sludgy oil can affect VVT operation and confuse the cam signal.
• Inspect the sensor connectors for brittle locking tabs, green corrosion, or oil in the plug. Clean and reseat if needed.
• Look for oil weeping at the timing cover where the sensor sits, a fresh O-ring can stop contamination of the pickup.
• If the light’s on with P0340/P0345, verify basics first: battery health, grounds, wiring continuity. Then scope or replace the sensor.

Replacement is straightforward: disconnect the battery, unplug the sensor, remove its small retaining bolt, twist and pull the sensor out, lightly oil the new O-ring, seat the new unit and torque to spec per the Toyota manual. On V6 models there’s typically one sensor per bank near the front timing cover by the intake cam. Use quality OEM-equivalent parts and clear codes after installation. If faults return, check the trigger wheel condition and VVT oil control valves, as oil pressure or actuator issues can mimic a bad sensor.

Where is the camshaft sensor on a 2011 Toyota Crown?

On the S200-series V6 engines, each bank has a camshaft position sensor mounted at the front timing cover near the intake cam. Looking from the front of the car, one sits on Bank 1 and the other on Bank 2. Access is usually from the top under the engine cover, sometimes intake ducting needs to come off for better reach.

The hybrid 2GR-FXE layout is similar, with sensors at the cam ends feeding the ECM for synchronisation and VVT control. Always confirm exact location against the engine label and the Toyota wiring diagram for GRS/GRS/GWS variants.

What are the common symptoms of a failing camshaft sensor on a Crown?

Typical tell-tales include a check engine light with P0340/P0345, longer cranking, rough idle, flat spots, poor fuel economy, or the engine dropping into limp mode. In some cases it may stall at idle or hot restart becomes a headache.

Before blaming the sensor, rule out fouled connectors, damaged wiring near the front cover, and oil contamination. Also consider VVT oil control valve performance and sludge, the ECU needs clean, stable cam timing to read a clean signal.

Can it be driven with a dodgy camshaft sensor?

It may start and run, but it’s a gamble. The ECU can fall back on the crank signal, yet timing and VVT will be compromised. That means potential stalling, higher fuel use and catalyst-unfriendly misfires. Best bet is to get it scanned, address wiring or oiling issues, and replace the sensor if it’s out of spec.
