2015 Toyota Vitz/Yaris crank angle sensor

Yes, the 2015 Toyota Vitz/Yaris uses a crank angle sensor (Toyota commonly calls it a crankshaft position sensor, NE signal). This is documented in Toyota service literature for the XP130-series, including the Engine Control System sections of the repair manual and the Electronic Wiring Diagram, which show the NE sensor input to the ECM on the 1KR‑FE (1.0L), 1NR‑FE (1.3L), 1NZ‑FE (1.5L) and even the 1ND‑TV (1.4D) engines. Toyota parts catalogues for these engines also list a dedicated crankshaft position sensor, confirming it’s a fitted, relevant component on the 2015 Vitz/Yaris.

On this model, the crank angle sensor keeps the engine in sync. It “reads” a toothed wheel on the crankshaft and feeds precise position and speed information to the engine control module. That’s how the ECM times spark and fuel injection to the exact degree, works out misfire detection, and lines up with the cam sensor for proper phasing. If the sensor signal is missing or erratic, the engine can be hard to start, run roughly, or not run at all.

It’s not a scheduled replacement item in normal servicing, but it’s worth a look whenever the bonnet is up. A quick inspection of the sensor’s connector and wiring loom for rubbing, oil contamination, or water ingress can save dramas later. Oil leaks from the front crank seal or a weeping timing cover can soak the area—clean that up and sort the leak so the sensor isn’t bathed in grime. If the check engine light pops up with codes like P0335–P0339, or there’s intermittent stalling, long cranks, or sudden cut-outs, testing the sensor output and harness is the next step.

Replacement is straightforward with the right access. The sensor sits low on the block near the crank pulley or bellhousing depending on engine variant. Disconnect the battery, safely raise the vehicle if needed, unplug the connector, remove the single retaining bolt, and ease the sensor out. Lightly lubricate the new O‑ring, seat the sensor squarely, and tighten to the manufacturer’s spec. Route the loom exactly as per the original clips to avoid heat and chafing, then clear any stored DTCs and road test. The ECM generally relearns automatically after a few kilometres of mixed driving.

Go for a quality OEM-equivalent sensor—cheapies can produce noisy signals that cause false misfire counts. For high‑kilometre cars, it’s also smart to inspect the crank pulley reluctor and check for wiring abrasion near the alternator where heat and vibration are highest. With clean connections and a healthy sensor, the Vitz/Yaris will start crisply and run smoothly without a fuss.

• Common symptoms: hard starting or no-start, rough idle, stalling, poor fuel economy, check engine light (P0335–P0339).
• Service tip: keep the area clean and dry, fix oil leaks that can contaminate the connector.
• After replacement: clear codes and confirm stable RPM and timing via a scan tool during a test drive.

Popular questions

Where is the crank angle sensor on a 2015 Vitz/Yaris?
It’s mounted low on the engine block, typically near the crank pulley at the front or at the bellhousing area, depending on engine. Access is usually from underneath with the splash shield off, though some variants can be reached from above with the right spanner and extension.

Can you drive with a failing crank angle sensor?
It might run intermittently, but it can also stall without warning or refuse to start. That’s not the sort of problem to gamble with in Aussie or Kiwi traffic. If you’re seeing long cranks, cut-outs, or a P0335 code, get it checked and sorted pronto.

Does it need routine replacement?
No, it’s not a consumable. Replace only if it’s faulty or damaged. During regular servicing, a visual check of the wiring, connector, and surrounding oil seals is enough. If symptoms arise, test first—don’t just throw parts at it.
