Parts for your 2007 Toyota Aurion-Crank angle sensor

2007 Toyota Aurion crank-angle sensor

Technical conclusion: The 2007 Toyota Aurion (GSV40R) with the 2GR-FE 3.5‑litre V6 does use a crank-angle sensor (crankshaft position sensor). This is documented in Toyota’s Repair Manual for the 2GR‑FE on TIS, which includes a dedicated “Crankshaft Position Sensor” section and fault-finding for DTC P0335. The Toyota Electronic Parts Catalogue for GSV40R likewise lists a “Sensor, Crank Position” mounted on the timing chain cover. Those factory sources confirm the part is fitted and essential to engine management on this model.

Under the bonnet of a 2007 Aurion, the crank-angle sensor plays a quiet but critical role. It tracks crankshaft speed and exact position so the ECU can fire the spark and inject fuel at the right moment, and it also helps the VVT‑i system stay in sync with the cam sensors. If this little sensor goes off, the car may crank without starting, stumble, or throw a check engine light with codes like P0335. Fuel economy and smoothness can take a hit too.

It’s not a scheduled replacement item, but it’s smart to give it some attention during major services, especially on higher‑kilometre cars. A quick visual once-over goes a long way: make sure the connector’s latch is sound, the wiring sheath isn’t brittle, and there’s no oil weep from the timing cover tracking into the plug. Because the sensor tip reads a toothed wheel, metallic debris can stick to it—worth checking if you ever have it out. Avoid blasting the area with a pressure washer, moisture in that connector can cause dramas.

If replacement’s on the cards, it’s a fairly tidy job for a competent DIYer with basic spanners, or any workshop. Disconnect the battery, unplug the sensor at the lower front of the engine (timing cover area), remove the retaining bolt, then twist and pull the sensor straight out. Fit a new O‑ring, lightly oil it, seat the new sensor, and torque the bolt to the factory spec from the Toyota manual. Reconnect, clear codes with a scan tool, and take it for a drive. Unlike some systems, the Aurion’s ECU generally doesn’t need special programming for a new crank sensor—just make sure no other faults are present.

• Common signs it’s unhappy: long cranking, sudden stall, rough idle, poor economy, or a no‑start with a check engine light.
• Best practice: use a quality OEM‑equivalent sensor, keep the connector clean and dry, and replace the O‑ring to prevent oil leaks.

Where is the crank-angle sensor on a 2007 Aurion?

It’s mounted through the timing chain cover at the front of the engine, near the crank pulley. Most techs access it from underneath after removing the lower splash shield. Look for a small two‑wire sensor held by a single bolt.

What are the common symptoms of a failing crank-angle sensor on an Aurion?

Expect hard starting or a no‑start, intermittent stalling, rough running at idle, and a check engine light—often with codes like P0335. Fuel economy can drop and the engine may feel flat or hesitant.

Does the Aurion need any programming after replacing the crank sensor?

Generally no. The 2GR‑FE is plug‑and‑play for this sensor. Clear any stored codes, verify live data looks normal, and road‑test. If other faults remain, address them before calling it fixed.
