Parts for your 2008 Toyota Aurion-Crank angle sensor

2008 Toyota Aurion crank angle sensor (2GR‑FE)

Technical verdict: the 2008 Toyota Aurion (GSV40, 2GR‑FE 3.5‑litre V6) is fitted with a crank‑angle sensor, commonly called the crankshaft position (CKP) sensor. This is documented in Toyota’s Aurion GSV40 repair manual for the 2GR‑FE under Engine Control System (SFI) including DTC P0335 Crankshaft Position Sensor, the Sensor Locations diagram, and the Aurion Electrical Wiring Diagram (EWD), which show a CKP sensor on the lower timing chain cover providing the NE signal to the ECM. Major parts catalogues for the 2GR‑FE likewise list a crank sensor for 2006–2011 Aurion/Camry V6 models.

The crank‑angle sensor on a 2008 Aurion keeps the engine’s timing spot on. It tracks the crankshaft’s exact position and speed so the ECM can fire the spark and inject fuel at the right moment, sync with the cam sensors for VVT‑i control, and monitor for misfires. If the sensor signal drops out, the Aurion can be hard to start, stall when hot, run rough, or log a check‑engine light with codes like P0335.

It’s not a scheduled service item, but it does appreciate a bit of care. During routine servicing, a quick look under the bonnet and from underneath (with the right safety stands) to check the CKP harness and connector for chafing, oil contamination, or brittle insulation is worthwhile. Oil weep from the timing cover or a crank seal can coat the sensor and connector over time, so fixing leaks early helps sensor longevity.

Replacement on the 2GR‑FE is straightforward for a competent home mechanic. The sensor sits on the lower timing chain cover near the crank pulley, normally accessed from underneath after removing the right‑hand splash shield. Disconnect the battery, unplug the connector, remove the single retaining bolt, twist and withdraw the sensor, and swap in a quality replacement with a fresh O‑ring lightly oiled. Route the loom as per factory clips, refit the bolt to the workshop‑manual torque, clear any fault codes, and let the engine idle so the ECM can relearn. If the old unit failed intermittently when hot, a road test to full temperature confirms it’s sorted.

Pro tips for the Aurion owner:

• Use OEM or a trusted brand, cheap sensors can cause false triggers.
• If the engine cranks but won’t fire, check for P0335–P0339 before throwing parts.
• A scope trace or live‑data RPM during crank is the quickest diagnosis.

Backed by Toyota literature for the 2GR‑FE, the CKP works alongside the two cam sensors to keep the big V6 smooth, efficient, and ready for long kilometres.

Where is the crank angle sensor on a 2008 Toyota Aurion?

On the 2GR‑FE V6 it’s mounted on the lower timing chain cover near the crankshaft pulley, typically accessed from underneath after removing the right‑hand splash shield. The connector points upward and the sensor is held by a single bolt with an O‑ring seal.

What symptoms show a failing crank angle sensor on an Aurion?

Common signs include long crank/no‑start, random stalling when hot, rough idle, hesitant acceleration, and a check‑engine light. Fault codes often include P0335 (CKP circuit) and sometimes companion cam/crank correlation codes. Live‑data RPM dropping to zero during crank is a red flag.

Does the Aurion’s crank angle sensor need routine replacement?

No routine interval. Many last well past 150,000 km. Replace when there are fault codes or confirmed symptoms. Keeping oil leaks in check and the connector clean helps the sensor live a long life.
