Parts for your 2006 Toyota Ractis-Crank angle sensor

2006 Toyota Ractis crank angle sensor — what it does and how to look after it

Yes, the 2006 Toyota Ractis is fitted with a crank angle sensor (Toyota typically calls it the crankshaft position sensor, CKP). Technical sources that reference this include: Toyota Ractis (NCP100/NCP105/SCP100) Electrical Wiring Diagram showing the CKP “NE” signal to the ECM, Toyota 1NZ‑FE and 2SZ‑FE Engine Control (SFI) repair manual sections describing the CKP/NE sensor operation and DTCs P0335–P0339, and Toyota Electronic Parts Catalogue listings that identify a crankshaft position sensor for these chassis codes. Together they confirm the sensor is standard on 1.3‑litre 2SZ‑FE and 1.5‑litre 1NZ‑FE Ractis models.

On a 2006 Ractis, the crank angle sensor feeds the engine computer exact crankshaft position and RPM. That data lets the ECM spark the plugs and time the fuel injectors right on the money, helps with cold starts, and allows accurate misfire detection. If the signal goes missing or mucks up, the Ractis can be hard to start, stall at the lights, feel flat off the mark, and light the check engine lamp with codes like P0335.

There’s no scheduled replacement for the crank angle sensor — it’s a solid-state unit that usually lasts the life of the vehicle. As part of regular servicing under the bonnet, it’s smart to do a quick visual once-over: check the sensor connector for green crusty corrosion, make sure the wiring loom isn’t rubbing on brackets, and keep an eye out for oil leaks from the timing cover that could contaminate the sensor. If drivability issues pop up, a scan for fault codes and a look at live RPM while cranking will quickly point you in the right direction.

Replacement is straightforward for a competent DIYer with basic spanners:

• Disconnect the battery and let the engine cool.
• Locate the sensor on the engine block/timing cover near the crankshaft pulley area, unplug it, and remove the retaining bolt.
• Swap the O-ring if supplied, install the new sensor, and torque the bolt to spec.
• Reconnect, clear codes, and road test. No special relearn is usually required on Toyota, the ECM adapts as you drive.

Choosing a genuine Toyota or top-shelf aftermarket sensor is worth it — it avoids nuisance faults and signal noise. If the old sensor tip is coated in metal fuzz or engine oil, that’s a clue to clean up the area and check for underlying issues. Under normal Kiwi and Aussie conditions, a well-fitted CKP sensor doesn’t need fettling — just keep the wiring healthy and the engine free of leaks, and it’ll keep the Ractis purring for many kilometres.

• Where is the crank angle sensor on a 2006 Toyota Ractis?
  It’s mounted to the engine block/timing cover near the crankshaft, reading a toothed wheel on the crank. Access is from the front of the engine bay, a torch helps to spot the connector and single retaining bolt.
• Can a crank angle sensor be cleaned or does it have to be replaced?
  If it’s just light debris or oil film on the tip, a careful clean can restore a healthy signal. If there’s internal damage, cracked plastic, or recurring DTCs (like P0335), replacement is the reliable fix.
• Do I need a relearn after replacing the sensor?
  On Toyota Ractis models, no special relearn is typically required. Clear the codes, start the engine, and take a short drive so the ECM can adapt. If issues persist, recheck wiring and connector pins.
