Parts for your 2022 Toyota Prius-Crank angle sensor

2022 Toyota Prius crank-angle sensor (crankshaft position sensor)

Yes, the 2022 Toyota Prius is fitted with a crank-angle sensor, more commonly called the crankshaft position (CKP) sensor. Toyota’s technical literature for the 2022 Prius (XW50, 2ZR-FXE) — including the Toyota Repair Manual (TIS), Electrical Wiring Diagram (EWD), and New Car Features (NCF) — identifies the CKP sensor, along with related diagnostic trouble codes P0335–P0339 for the CKP circuit. That confirms it’s a relevant, essential component on this hybrid.

On the 2022 Prius, the crank-angle sensor feeds the engine control module precise data on crank speed and angle, so the ECM can time injection and spark perfectly. In a hybrid like this, that information is also crucial for smooth engine stop–start events and for the hand‑off between electric and petrol power. If the CKP signal goes missing or erratic, the engine may crank but not fire, stall as it tries to start, or light the MIL with a CKP code. It also underpins misfire monitoring and helps keep emissions in check.

As for servicing, the crank-angle sensor isn’t a scheduled replacement item. It’s generally “fit and forget”, but smart owners and workshops still keep an eye on it during routine services:

• Inspect the CKP wiring and connector (near the timing cover) for rub-through, oil contamination, or corrosion.
• Avoid blasting the area with high‑pressure water, moisture in the plug causes intermittent faults.
• Address any engine oil leaks promptly so the sensor O‑ring and reluctor area stay clean.

Replacement is straightforward for a trained tech. Under the bonnet, disable READY, remove the key/fob from the cabin, and disconnect the 12‑V negative terminal to prevent an unexpected engine start. Access is typically from underneath or the right‑hand wheel well. Unplug the connector, remove the retaining bolt, and gently twist the sensor free. Lightly oil the new O‑ring, install, and tighten to the factory torque spec as listed in the Toyota Repair Manual. After refit, clear any DTCs and verify smooth hybrid start–stop operation. No special programming is normally required.

Typical symptoms that point to a crook CKP sensor or circuit include:

• Crank/no start, or rough starts when the petrol engine kicks in.
• Stalling during hybrid transitions, poor fuel economy, or erratic tach readings.
• Stored codes P0335–P0339.

Popular questions

Where is the crank-angle sensor on a 2022 Prius?
The CKP sensor is mounted on the engine block near the crankshaft/timing cover area, reading a toothed reluctor on the crank. Access is typically from underneath or via the right‑hand wheel well once the engine under‑cover is removed. The EWD and Repair Manual diagrams show the exact connector routing and mounting point.

What fault codes relate to a bad crank-angle sensor?
Common codes include P0335 (CKP Circuit) through to P0339 variants for signal range, performance, and intermittency. Drivers may notice hard starting, stalling as the engine tries to engage, or the MIL on. A scan with live data helps confirm loss or distortion of the CKP signal before replacement.

Does the crank-angle sensor need regular replacement?
Not usually. It’s a non‑service item and is replaced on condition. During routine servicing, checking the harness, connector seals, and nearby oil leaks is enough. If symptoms or codes appear, proper diagnosis should come first to rule out wiring and connector issues before fitting a new sensor.
