Parts for your 2019 Toyota Rav4-Crank angle sensor

2019 Toyota RAV4 crank-angle-sensor (crankshaft position sensor)

Based on technical documentation, the 2019 Toyota RAV4 (XA50 platform) does use a crank sensor. Toyota labels it the Crankshaft Position Sensor (often abbreviated CKP), which fulfils the same role as a traditional “crank-angle sensor”. This is confirmed in Toyota’s 2019 RAV4 Repair Manual (Engine/Hybrid System sections for M20A-FKS, A25A-FKS and A25A-FXS engines – “Crankshaft Position Sensor”), the 2019 RAV4 Electrical Wiring Diagram showing the CKP (NE) signal to the ECM, and DENSO technical literature describing the CKP’s function in determining crank angle and engine speed.

On the 2019 RAV4, the crankshaft position sensor keeps the engine control module in the loop on exactly where the crank is and how fast it’s spinning. That lets the ECM time fuel injection and spark precisely, and on hybrid variants, it also helps the system start and stop the engine smoothly. If this little sensor goes out of whack, owners may notice hard starting, random stalling, a shaky idle, misfires, or the check-engine light with codes like P0335–P0339.

It’s not a scheduled service item, but it’s a good idea to give it a once-over during major services. A quick visual check for oil contamination on the connector, brittle wiring, or damage around the sensor mount can save headaches later. If there’s a no-start or intermittent stall, scan it first and confirm live CKP data before swapping parts.

When replacement is needed, most owners and workshops opt for a genuine or quality OE-equivalent sensor. The unit is mounted to the engine block where it reads a toothed reluctor on the crankshaft, access is typically from underneath. Replacement basics:

• Disconnect the battery and allow the engine to cool.
• Unplug the CKP connector, check for oil ingress or corrosion.
• Remove the retaining bolt, ease out the sensor, and inspect the O-ring.
• Lightly oil the new O-ring, install the sensor squarely, and tighten to the manufacturer’s torque spec.
• Reconnect, clear any fault codes, and verify live data and a clean restart.

There’s no special relearn on most Toyota setups, but it’s smart to clear codes and road test. Keeping the loom clipped away from heat and not blasting the area with a pressure washer will help the new sensor live a long life. For budgeting, the sensor itself is usually modestly priced and labour is typically under an hour on a hoist in most workshops around Australia and New Zealand.

Popular questions about 2019 Toyota RAV4 crank-angle-sensor

Does the 2019 RAV4 have a crank-angle sensor?
Yes. Toyota refers to it as the crankshaft position sensor (CKP). It measures crank angle and speed so the ECM can time spark and fuel precisely, and it’s essential for starting and smooth running.

Where is the crankshaft position sensor on a 2019 RAV4?
It’s mounted to the engine block, reading a toothed ring on the crankshaft. Access is commonly from underneath the vehicle. Exact orientation can vary by engine (2.0-litre, 2.5-litre, or hybrid), but it’s typically low on the block with a two-pin connector leading to the engine loom.

Can a crankshaft position sensor be cleaned or should it be replaced?
If it’s just light debris on the tip, a gentle clean can help, but internal sensor faults or wiring/connector damage call for replacement. Always inspect the connector for oil contamination and repair any loom damage before fitting a new sensor.
