Parts for your 2011 Toyota Aurion-Crank angle sensor

2011 Toyota Aurion crank-angle sensor (crankshaft position sensor) – purpose, care and replacement

For the 2011 Toyota Aurion (GSV40, 2GR‑FE V6), a crank-angle sensor is absolutely fitted and relevant. Toyota refers to it as the crankshaft position sensor (CKP). This is confirmed in Toyota’s Aurion/Camry GSV40 Repair Manual under Engine Control (SFI) and the 2GR‑FE New Car Features publication, both of which show the ECM using CKP and CMP signals for ignition and injection timing. Toyota’s Electronic Parts Catalogue for the Aurion also lists a “Sensor, Crank Position” for the 2GR‑FE (commonly referenced as part no. 90919‑05048 or superseding numbers), confirming factory fitment.

On the Aurion, the crank-angle sensor keeps the 2GR‑FE running right by telling the engine control module exactly where the crankshaft sits and how fast it’s spinning. With that info, the ECM fires the injectors and spark plugs at the perfect moment, manages VVT‑i angles, and keeps the idle smooth. If this signal drops out or goes noisy, the engine can be hard to start, stumble, or stall, and the check engine light will often log codes like P0335.

It’s not a routine “replace every X km” item, but it deserves a look during regular servicing. A quick visual under the bonnet for oil leaks, damaged wiring, or a loose connector around the lower rear side of the engine block (transaxle end) can save headaches. Oil wicking into the plug or a brittle harness is a common cause of intermittent faults.

If replacement is needed, it’s a straightforward single-bolt job for most workshops. Usual approach:

• Disconnect the battery and let the engine cool.
• Access the sensor at the lower rear of the block, unplug the connector.
• Remove the retaining bolt, twist the sensor gently to free the O‑ring, and withdraw.
• Lightly oil a new genuine O‑ring, install the new sensor squarely, and torque the bolt to spec (around 8–10 N·m, check current workshop data).

Best practice is to use a genuine or high-quality equivalent sensor and replace the O‑ring to prevent future leaks. After refitting, clear any codes and verify live data and crank sync with a scan tool. Owners who’ve had random stalls, hot no‑starts, or a tach that drops to zero whilst cranking will often notice an immediate improvement once a flaky sensor or connector is sorted. Keeping the area clean, the loom clipped away from heat, and fixing minor oil seepage early will extend the life of the sensor and keep the Aurion happy on Aussie and Kiwi roads.

Where is the crank-angle sensor on a 2011 Aurion?

It’s mounted low on the engine block at the transaxle end (rear of the transverse V6), held by a single bolt and sealed with an O‑ring. Access is from the top or underneath depending on tools and lift.

What symptoms point to a failing crank-angle sensor?

Hard starting when hot, random stalls, misfires at low speed, the tacho not moving during cranking, and a check engine light with codes like P0335. Wiring damage or oil in the connector can mimic a bad sensor.

Does it need periodic servicing?

No scheduled replacement, but it’s smart to inspect the connector and surrounding area at service time, fix any oil leaks, and ensure the harness isn’t rubbing or cooked by exhaust heat.
