Parts for your 2006 Toyota Aurion-Camshaft sensor

2006 Toyota Aurion camshaft sensor — fitted, vital and worth keeping happy

Per Toyota’s technical literature — the Aurion GSV40 (2006) with the 3.5‑litre 2GR‑FE V6 — the engine control system uses two camshaft position sensors (one per bank). This is confirmed in the Toyota Aurion GSV40 Repair Manual (Engine Control – SFI System, 2GR‑FE), the Toyota Electronic Parts Catalogue (EPC), and the 2GR‑FE New Car Features (NCF) guide. So yes, a camshaft sensor is absolutely used on the 2006 Aurion.

On this engine, the camshaft sensors (MRE/Hall‑effect style) feed the ECU precise cam angle data so it can run dual VVT‑i, time the sequential fuel injection, and validate crank correlation. That means smooth starts, decent fuel economy, solid power, and proper emissions control. When one goes out of sorts, the ECU will usually toss a warning light and a code (think P0340/P0345 families), and the car may crank longer, stumble, lose power, or drop into a limp‑home strategy.

They’re not a regular “replace by kilometres” service item, but a bit of preventative love goes a long way. Fresh, correct‑grade oil helps VVT operation and keeps debris off the magnetic tips. During routine servicing, it’s smart to:

• Inspect the sensor plugs and wiring looms for heat damage or oil saturation.
• Check for rocker cover oil leaks that can wick into the connectors.
• Scan for history codes after any driveability complaint.

If replacement is needed, each sensor sits at the end of a cylinder head (one per bank). Access varies, the front bank is straightforward, the rear can be tighter under the cowl. Basic steps:

1. Disconnect the negative battery terminal.
2. Unplug the sensor connector, press the tab, don’t yank the wires.
3. Remove the retaining bolt (typically a 10 mm head). Note: torque on refit is modest — around 8–10 N·m, always verify against the Toyota manual.
4. Twist and pull the sensor out, replace the O‑ring, lightly oil it, then seat the new sensor squarely.
5. Reconnect, clear codes, and road test. No special relearn is usually required on the 2GR‑FE.

Genuine or high‑quality OEM‑equivalent sensors are recommended to keep VVT timing crisp. If the Aurion is showing cam/crank correlation faults, rough idle, or poor fuel economy, a proper diagnosis (oil condition, VVT operation, wiring integrity) should come before parts‑darting. With the right part and a careful install, most owners are back under the bonnet for little more than a cuppa’s worth of time.

Popular questions

Does the 2006 Aurion have one or two camshaft sensors?
The 2GR‑FE V6 in the 2006 Aurion runs two camshaft position sensors — one for each cylinder bank. The ECU uses both signals for dual VVT‑i control and accurate injection timing.

What are the common signs of a failing camshaft sensor on an Aurion?
Long cranking, rough idle, hesitation, reduced power, and a check engine light are typical. Scan tools often show codes like P0340 or P0345. Always inspect oil condition and wiring before condemning the sensor.

Is it safe to keep driving with a dodgy camshaft sensor?
It’ll usually run, but performance and fuel economy can drop, and it may stall. Best to sort it promptly to avoid getting stranded and to prevent related issues with VVT operation.
