Parts for your 2006 Toyota Aurion-Crank angle sensor

2006 Toyota Aurion crank angle sensor

Technical sources confirm the 2006 Toyota Aurion (GSV40, 2GR‑FE V6) does use a crank angle sensor, more commonly called the crankshaft position (CKP) sensor. Toyota’s SFI System documentation for the 2GR‑FE details the NE crankshaft signal and related DTCs P0335/P0339, the Toyota Electronic Parts Catalogue (EPC) lists a “Sensor, Crank Position” for GSV40R, and independent repair manuals for the Aurion (e.g., Gregory’s/Autodata coverage of the 2GR‑FE) show the CKP in the engine management diagram and component locations. That settles it: the Aurion is fitted with a crank angle sensor and it’s vital to how the engine runs.

On the 2GR‑FE, the crank angle sensor reads a toothed reluctor on the crank to tell the ECU exactly where the crankshaft is and how fast it’s spinning. Paired with the cam sensors, it lets the ECU time fuel injection and spark bang-on, manage VVT-i, and detect misfires. If it drops out, the engine can be hard to start, run rough, or stall, in many cases it simply won’t fire at all.

There’s no scheduled maintenance for the CKP on a 2006 Aurion, but smart servicing includes a quick look whenever the car’s up on stands. The sensor sits low on the block near the transmission bellhousing area, so it can cop road grime and the odd oil weep. Keep the connector clean and clipped, and don’t ignore leaks from the timing cover or oil cooler that could soak the sensor body.

When replacement is on the cards—usually after fault codes like P0335/P0339, intermittent stalling, or a no‑start—most workshops will:

• Disconnect the battery and raise the front for under‑car access.
• Remove the splash shield, unplug the sensor, undo the single retaining bolt, and ease the sensor out.
• Lightly oil the new O‑ring, seat the new sensor squarely, refit the bolt to spec, reconnect, and clear codes.

Owners generally opt for genuine Toyota/Denso or high‑quality OEM‑equivalent sensors, bargain units can introduce flaky signals that are a nightmare to chase. After fitting, a brief road test and a live‑data check (crank and cam sync, RPM signal) help confirm it’s all behaving. Given the Aurion’s timing chain setup and tight engine bay, leaving this job to a competent technician is often the least stressful path, but a careful home mechanic with proper safety gear can tackle it.

Popular questions

Where is the crank angle sensor on a 2006 Toyota Aurion?
It’s mounted low on the 2GR‑FE engine block near the transmission bellhousing area. Access is usually from under the car after removing the front lower splash shield. Look for a small sensor with a single bolt and a two‑pin or three‑pin connector.

What symptoms point to a failing crank angle sensor on an Aurion?
Common signs include long crank or no‑start, random stalling, rough idle, and the check‑engine light. Scan tools often show codes like P0335 or P0339. If the signal drops out completely, the engine typically won’t run.

Can the crank angle sensor be cleaned, or does it need replacing?
If it’s just dirty with light debris, a careful clean of the tip and connector can help. But if the internal electronics are failing or the signal is erratic, replacement is the reliable fix. Always inspect and fix any oil leaks that might re‑contaminate the area.
