Parts for your 2013 Toyota Bb-Crank angle sensor

2013 Toyota bB crank angle sensor — what it does, and how to look after it

Yes — the 2013 Toyota bB is fitted with a crank angle sensor (a.k.a. crankshaft position sensor). Technical references that confirm this include the Toyota bB QNC20/21/25 Repair Manual, the Toyota Electronic Parts Catalogue for the 2013 model year, and the Daihatsu K3‑VE/3SZ‑VE engine service literature used in the bB. These sources list and illustrate the CKP/NE sensor mounted to read a toothed reluctor on the crank.

On this model, the crank angle sensor constantly reports the crank’s exact position and speed to the engine ECU. That info is used to time spark and fuel injection, sync with the cam sensor, and monitor for misfire. If the sensor signal is missing or flaky, the bB can be hard to start, run rough, lose power, or stall — and it’ll usually flag a fault code like P0335.

It’s not a regular “service item”, but it’s smart to consider it during scheduled maintenance. During routine servicing, a technician can visually check the sensor body and wiring, especially around the front of the engine where heat and oil weeps can live. Oil leaks from the crank seal can contaminate the sensor, and broken loom clips can let the harness chafe.

• Typical symptoms: long crank/no start, sudden cut‑out when hot, rough idle, poor fuel economy, tacho dropouts, and DTCs P0335–P0339.
• Basic checks: inspect the connector for corrosion, ensure the harness isn’t rubbing, and look for metal debris stuck to the sensor tip.

If replacement is needed, go for a quality OEM‑equivalent sensor with the correct O‑ring. The unit is mounted to the engine to read the crank’s reluctor wheel, access varies slightly by engine (K3‑VE or 3SZ‑VE), but it’s typically at the front of the block near the crank pulley. Disconnect the battery, unplug the connector, remove the retaining bolt, swap the sensor and O‑ring, and refit to factory torque. Check that the sensor sits cleanly and the air gap isn’t obstructed by debris. Clear any stored codes and road‑test, no special relearn is usually required on these engines.

With a healthy crank angle sensor, the bB starts crisply, idles smoothly, and keeps its fuel use tidy — exactly what owners in Australia and New Zealand expect from a well‑looked‑after Toyota.

FAQs

Does the 2013 Toyota bB have a crank angle sensor?
Yes. Toyota’s bB repair manual and the Toyota EPC list a crankshaft position (crank angle) sensor on 2013 QNC2# models using the K3‑VE or 3SZ‑VE engines. It’s fitted to read the crank’s reluctor wheel for precise ignition and injection timing.

What are the signs the crank angle sensor is failing?
Common signs include hard starting or a no‑start when hot, intermittent stalling, rough idle, loss of power, and poor economy. The check engine light may log P0335–P0339. A quick harness and connector inspection can save time before replacing parts.

Can it be cleaned, or should it be replaced?
If the tip has light debris or oil film, a careful clean and refit can help. If the sensor has internal faults, cracked wiring, or persistent DTCs return after cleaning, replacement is the proper fix. Always use a new O‑ring and secure the loom correctly.
