Parts for your 2016 Toyota Rav4-Camshaft sensor

2016 Toyota RAV4 camshaft sensor — what it does and how to look after it

Yes, the 2016 Toyota RAV4 uses a camshaft position sensor. Toyota’s service literature for the 2016 RAV4 (Toyota TIS repair manual for the 2AR‑FE petrol and 2AR‑FXE hybrid engines) specifies a camshaft position sensor (often labelled “G2”) mounted on the cylinder head. The Toyota Electrical Wiring Diagram for the same model shows the G2 signal feeding the ECM to enable sequential fuel injection and variable valve timing control. Toyota’s DTC list for this vehicle also includes P0340/P0341 for camshaft position sensor circuit/performance, confirming the part is fitted and monitored.

On this RAV4, the camshaft sensor tells the engine computer exactly where the cam is in its rotation. Paired with the crank sensor, it lets the ECM fire the injectors in the right order, time the spark properly, and trim VVT‑i operation for smooth running and decent fuel economy. When it goes off song, drivers might see a check engine light, rough idle, hard starts, flat spots under load, or poor fuel use. Hybrids can refuse to start the petrol engine or start/stop erratically.

There’s no set service interval for the cam sensor, it’s a “replace when faulty” item. Still, a bit of care goes a long way:

• Keep the connector clean and clipped tight, moisture or oil wicking into the plug can skew the signal.
• If there’s an oil weep from the sensor O‑ring, replace the O‑ring to prevent contamination.
• Investigate any DTCs (e.g., P0340/P0341) with a scan tool before throwing parts at it—wiring damage and poor grounds are common culprits.

Replacement on a 2016 RAV4 is straightforward under the bonnet. Disconnect the battery negative, unplug the sensor, remove the retaining bolt, ease the sensor out, lightly oil the new O‑ring, and refit. Clear codes and road‑test. No special programming or “relearn” is usually needed, the ECM adapts on the fly. Use a quality OE‑spec sensor to keep the VVT happy and avoid intermittent faults. If the engine has seen sludge or extended oil intervals, consider an oil and filter service at the same time—clean oil helps the cam timing system behave itself.

For anyone touring across Aussie or Kiwi kilometres, it’s a small part that keeps the RAV4 feeling lively and reliable. Catch issues early with a quick scan and visual check during regular servicing.

FAQs

Where is the camshaft sensor on a 2016 RAV4?
It’s mounted on the cylinder head near the camshaft sprocket area, accessible from the top of the engine bay. On the 2AR‑FE and 2AR‑FXE, look for a small sensor held by a single bolt with a two‑ or three‑pin connector.

What are the signs the camshaft sensor is failing?
Common signs include hard starting, rough idle, hesitation, poor fuel economy, and a check engine light—often with codes like P0340 or P0341. On the hybrid, the petrol engine may fail to start when commanded.

Can the RAV4 be driven with a bad camshaft sensor?
It may run in a limp or fallback mode, but performance and starting can be unreliable. It’s best to diagnose and sort it promptly to avoid stalling or further issues.
