Parts for your 2010 Toyota Aurion-Camshaft sensor

2010 Toyota Aurion Camshaft Sensor

Based on Toyota’s own technical literature, the 2010 Toyota Aurion (GSV40 series with the 2GR‑FE 3.5‑litre V6) is fitted with camshaft position sensors. The Toyota Repair Manual for the Aurion and the Electrical Wiring Diagram identify two camshaft position sensors (RH and LH) used by the ECM for Dual VVT‑i control, and the factory DTC list includes cam/crank related codes such as P0340 and P0345. So yes—this model absolutely uses camshaft sensors, and they’re an essential part of how it runs.

On the Aurion’s 2GR‑FE, the camshaft sensor’s job is to let the engine computer know exactly where each camshaft is in its rotation. Paired with the crank sensor, it allows precise fuel injection and spark timing and lets Dual VVT‑i adjust valve timing for smooth power and good economy. If a sensor goes out of whack, the car can become hard to start, run rough, chew through more fuel, or even drop into limp mode.

They’re not a scheduled replacement item, but they do benefit from a bit of attention during servicing. Under the bonnet, each sensor sits on the end of a cylinder head near the timing chain cover—one for Bank 1 and one for Bank 2. A quick visual check for oil seepage around the O‑ring, brittle wiring, or loose connectors is worthwhile at major services. Keeping connectors clean and dry helps prevent intermittent faults.

• Common signs of trouble: extended cranking, misfires at idle, flat spots on acceleration, higher fuel use, and warning lights with codes like P0340/P0345 or correlation codes (P0016–P0019).
• Replacement tips: disconnect the battery, unplug the connector, remove the retaining bolt, and pull the sensor straight out. Lightly oil a new O‑ring, seat the new sensor squarely, and refit the bolt and plug. Clear codes and verify live data.
• Parts choice: quality OEM or reputable aftermarket sensors tend to last longer and read more consistently, which matters for VVT‑i control.

If faults keep returning, it’s smart to check the timing chain condition, camshaft timing actuators, and wiring integrity, as the sensor only reports what it “sees”. A quick scan with proper diagnostic equipment will save time and money.

FAQs

How many camshaft sensors does a 2010 Aurion have?
The 2GR‑FE V6 in the 2010 Aurion uses two camshaft position sensors—one on each bank (RH and LH). Both are critical for Dual VVT‑i, so a fault on either side can affect starting, drivability, and fuel use.

Where are the camshaft sensors located?
Each sensor is mounted on the end of a cylinder head near the timing chain cover. With the engine cover removed, they’re accessible from the top of the engine bay, though clearance can vary depending on the side.

Is it okay to drive with a faulty camshaft sensor?
It may still run, but it can stall, run rich, and drop into limp mode. That’s not ideal for safety or the catalytic converters. Best to diagnose and replace the sensor promptly.
