2011 Toyota Vitz/Yaris Crank-Angle Sensor

Based on Toyota technical references, the 2011 Toyota Vitz/Yaris is fitted with a crank-angle sensor (commonly called the crankshaft position sensor, or CKP). Toyota’s engine control documentation for the 1KR‑FE, 1NR‑FE and 1NZ‑FE engines (SFI/EFI sections) identifies the CKP as the “NE” signal to the ECM, and Toyota’s diagnostic listings include DTCs like P0335–P0339 specifically for this sensor. The Toyota Electronic Parts Catalogue for chassis codes KSP130/NSP130/NCP131 also lists a crankshaft position sensor. So yes—this part is relevant and used on the 2011 Vitz/Yaris.

The crank-angle sensor’s job is to tell the engine computer exactly where the crankshaft is in its rotation and how fast it’s spinning. With that info, the ECM times fuel injection and spark so the little Yaris fires crisply, runs smoothly and sips fuel the way it should. The sensor reads a toothed reluctor wheel on the crank, every tooth passing the sensor creates a signal the ECM counts, letting it control ignition and injection down to the degree.

When the sensor starts to go out, the car can be a pain to start, may stall when warm, or throw a Check Engine Light with codes like P0335. Misfires, uneven idle, and a dead tach are all clues. Because the CKP is a critical input, a complete failure can cause a no‑start.

There’s no scheduled maintenance for the crank-angle sensor on a 2011 Vitz/Yaris, but a quick look during servicing goes a long way. Keep the connector clean and free of corrosion, and deal with any oil leaks around the front cover—the sensor doesn’t love being bathed in oil and grime.

Replacement is straightforward for a competent DIYer or any mechanic:

• Disconnect the battery, let the engine cool, and locate the sensor at the front or lower side of the block (engine variant dependent).
• Unplug the connector, remove the retaining bolt, and gently twist the sensor free. Don’t lever against the housing.
• Lightly oil the new O‑ring, install the new sensor, and tighten the bolt to factory spec (check the Toyota repair manual for the exact torque).
• Clear fault codes and take a short drive so the ECM relearns idle and timing trims.

Genuine or high‑quality aftermarket sensors work well, cheapies can cause intermittent dramas. If the Yaris shows hard starts or random stalls, testing the CKP should be near the top of the list.

Popular questions about the 2011 Toyota Vitz/Yaris crank-angle sensor

Where is the crank-angle sensor located on a 2011 Vitz/Yaris?
On most 1KR‑FE and 1NR‑FE engines it’s mounted low on the engine block near the crank pulley/front cover. Access is from under the bonnet or from below with the splash shield off. Exact position varies slightly by engine and market spec.

What are the symptoms of a failing crank-angle sensor?
Hard starting, random stalling when hot, uneven idle, lack of power, and a Check Engine Light with codes like P0335 are common. In some cases the engine won’t start at all because the ECM can’t see crank speed/position.

Does the crank-angle sensor need regular servicing?
There’s no set service interval. It’s a replace‑on‑failure item. During routine servicing, it’s worth checking for oil leaks, damaged wiring, or a loose connector to keep it happy for the long haul.
