Parts for your 2019 Toyota Rav4-Camshaft sensor

2019 Toyota RAV4 Camshaft Sensor — Purpose, Service Tips, and FAQs

Yes, the 2019 Toyota RAV4 is fitted with camshaft position sensors. This applies to both the 2.5‑litre petrol (A25A‑FKS) and the 2.5‑litre hybrid (A25A‑FXS) Dynamic Force engines used in AXAA/AXAH series RAV4s. Technical sources including Toyota’s Repair Manual (TIS) for 2019 RAV4 list diagnostic trouble codes P0340/P0345 for the camshaft position sensor circuits, and the New Car Features (NCF) manual for the A25A engines details camshaft position sensing for variable valve timing control. Toyota’s Electrical Wiring Diagram (EWD) for these models also shows dedicated camshaft position sensor circuits.

On this RAV4, the camshaft sensor feeds the engine ECU precise information about cam angle and phase. That data is critical for sequential fuel injection, ignition timing, variable valve timing (VVT‑i/VVT‑iE) control, smooth cold starts, and emissions. If a sensor begins to fail, owners may notice hard starting, rough idle, flat spots, reduced fuel economy, or the check engine light. The ECU can fall back to a basic strategy using the crank signal, but performance and drivability will suffer.

There’s no scheduled replacement interval for the camshaft sensor, it’s a solid‑state part designed to last the life of the vehicle. As part of servicing a 2019 RAV4, a technician will usually check for stored DTCs, inspect the sensor connectors and harness routing around the cam cover, and make sure engine oil is the correct grade and changed on time—clean oil helps the VVT system track accurately, which in turn keeps the sensor’s signal consistent.

When replacement is required, it’s a straightforward job on these engines, as the sensors are mounted at the top of the cylinder head. Best practice includes:

• Confirming fault codes (e.g., P0340/P0345) and symptoms before replacing parts.
• Inspecting the connector for oil intrusion, corrosion, or broken pins, and checking harness clips under the bonnet.
• Fitting an OE‑quality sensor with a new O‑ring, lightly oiled to avoid pinching.
• Torquing the retaining bolt to the spec in the Toyota service manual and clearing codes.
• Road‑testing and monitoring live data to confirm stable cam/crank correlation and VVT operation.

Quality diagnostics matter here: a persistent cam sensor code can also point to wiring damage, a timing issue, or a VVT actuator concern. Using genuine parts and methodical checks keeps the RAV4 running sweet and efficient across Aussie and Kiwi roads.

Popular questions about the 2019 Toyota RAV4 camshaft sensor

Does the 2019 RAV4 have one or two camshaft sensors?
The A25A Dynamic Force engines in the 2019 RAV4 use camshaft position sensing on both the intake and exhaust sides. That means two sensors are fitted, giving the ECU accurate control of VVT‑i/VVT‑iE and precise fuel and spark phasing.

Can a bad camshaft sensor damage the engine?
It usually won’t cause immediate mechanical damage, but it can lead to poor running, increased fuel use, and potential catalyst stress if misfires occur. It’s wise to fix the fault promptly to avoid drivability issues and emissions problems.

What’s the difference between the camshaft sensor and the crankshaft sensor on this RAV4?
The camshaft sensor reports the cam’s position for cylinder identification and valve timing control, while the crank sensor tracks engine speed and base position. The ECU needs both for the most accurate control, if the cam signal is lost, it can limp on crank data but with reduced performance.
