Parts for your 2000 Toyota Rav4-Crank angle sensor

2000 Toyota RAV4 crank-angle sensor (crankshaft position sensor) – purpose, fitment and servicing

Based on Toyota’s workshop literature for the 1AZ‑FE engine and wiring diagrams for the 2000–2005 RAV4 (ACA20/ACA21), plus the Toyota Electronic Parts Catalogue and independent data sets such as Autodata and Haynes, the 2000 Toyota RAV4 sold in Australia and New Zealand is fitted with a crank-angle sensor (commonly called the crankshaft position sensor or CKP). These sources show the CKP provides the “NE” signal the ECU uses for engine speed and crank reference. Note: very late first‑gen RAV4s with the older 3S‑FE in some markets used a distributor with built‑in pickups instead of a separate CKP, but the 2000 AU/NZ models with 1AZ‑FE have a dedicated CKP at the timing chain cover.

On the 2000 RAV4, the crank-angle sensor is the ECU’s heartbeat. It tracks crank speed and exact crank angle so the ECU can time spark and fuel precisely, often in sync with the cam sensor. If the CKP signal drops out or gets noisy, the RAV4 can crank but not start, stall when hot, misfire, or log trouble codes like P0335–P0339. Fuel economy can suffer and throttle response goes a bit doughy.

There’s no scheduled maintenance for the sensor itself, but it pays to check the connector and loom routing whenever the front of the engine is accessed. On the 1AZ‑FE, the sensor sits at the lower timing chain cover near the crank pulley, heat and oil weep can harden the O‑ring and make the plug brittle over time.

Replacement is straightforward DIY for a confident home mechanic: disconnect the battery, unplug the connector, remove the retaining bolt, twist and withdraw the sensor, lightly oil a new O‑ring, and refit to the clean bore. Use quality OEM‑equivalent sensors, bargain units can produce weak or erratic signals. Don’t yank on the wiring, and avoid getting sealant or debris on the magnetic tip. After installation, clear any fault codes and check live data (engine speed) to confirm a stable signal. If issues persist, inspect the harness for chafing and ensure the crank reluctor/target wheel isn’t damaged.

For older RAV4s still running the distributor‑based 3S‑FE, a separate crank-angle sensor may not be present, instead, the distributor’s internal pickups provide the same timing signals. The servicing approach is different there, focusing on the distributor, cap, rotor, and internal sensors.

Popular questions

Where is the crank-angle sensor on a 2000 RAV4?
On AU/NZ 2000 models with the 1AZ‑FE, it’s mounted in the lower timing chain cover by the crank pulley. Look down the front of the engine, you’ll see a small sensor with a single retaining bolt and a two‑ or three‑pin connector.

What are the symptoms of a failing crank-angle sensor?
Hard starting, intermittent stalling (often hot), sudden loss of power, misfires, poor fuel economy, and an engine light with codes like P0335. Sometimes it fails completely and the engine won’t fire at all.

Is it safe to keep driving with a dodgy crank-angle sensor?
Not really. It can cut out without warning, leaving the vehicle stranded. It’s best to diagnose promptly and replace the sensor or repair the wiring before it escalates.
