Parts for your 2010 Toyota Fortuner-Crank angle sensor

2010 Toyota Fortuner crank angle sensor — purpose, servicing and replacement tips

Based on Toyota technical documentation, a crank angle sensor is fitted to the 2010 Toyota Fortuner. Toyota refers to it as the Crankshaft Position Sensor (often the “NE” signal) in the Engine Control System sections of the Repair Manual and Electrical Wiring Diagram for the AN60-series Fortuner/Hilux. The Toyota Electronic Parts Catalogue also lists a crankshaft position sensor for both common 2010 Fortuner engines: the 3.0 D‑4D (1KD‑FTV) diesel and the 2.7 VVT‑i (2TR‑FE) petrol. These sources confirm the sensor is relevant and used on this model.

On a 2010 Fortuner, the crank angle sensor tracks the crankshaft’s exact position and speed so the ECU can time fuel injection and ignition spot on. Paired with the cam sensor, it knows which cylinder is on compression, helps the engine fire up cleanly, trims timing for smooth running, and monitors for misfires. If this sensor drops out, you’ll usually cop a no‑start, hard starting, rough idle, or limp‑mode with a check engine light. Typical fault codes include P0335–P0339.

It’s not a routine replacement item in scheduled servicing, but a quick look during major services pays off. Check the sensor body and connector for oil contamination, cracked insulation, or chafed wiring. Make sure the harness is clipped away from heat and moving parts, and that the sensor’s O‑ring isn’t weeping. Metal debris on a magnetic sensor tip can cause weak signals, so a gentle clean can help if recommended by the repair data.

• Common symptoms of trouble:
  • No‑start or extended cranking, especially hot
  • Intermittent stalling, poor acceleration
  • MIL on with P0335‑series codes
• Replacement and diagnosis tips:
  • Confirm with a scan tool and live data (engine speed signal), and inspect wiring first.
  • Use quality OEM‑equivalent parts, cheap sensors can give weak or noisy signals.
  • Lightly oil the new O‑ring, seat the sensor squarely, and torque to spec from the Toyota manual.
  • Clear codes and road‑test, no special relearn is typically required on these engines.

Location-wise, technicians will usually find the sensor mounted at the engine block or timing cover, reading a toothed reluctor on the crank. Access varies slightly between the 1KD‑FTV diesel and 2TR‑FE petrol, so check the model‑specific Toyota service information before diving in.

Popular questions about the 2010 Toyota Fortuner crank angle sensor

Does the 2010 Fortuner actually have a crank angle sensor?
Yes. Toyota labels it the Crankshaft Position Sensor (NE signal) in the factory Repair Manual and Wiring Diagram for the AN60‑series Fortuner. It’s essential for timing fuel and spark on both the 1KD‑FTV diesel and 2TR‑FE petrol.

Where is the crank angle sensor on a 2010 Fortuner?
It’s mounted to the engine and reads a toothed wheel on the crank. On the 2TR‑FE petrol it’s typically at the timing cover near the crank pulley, on the 1KD‑FTV diesel it’s on the block, positioned to read the crank reluctor. Exact access points vary, so always refer to the Toyota service manual.

Does a new sensor need programming?
Generally, no. Fit the sensor, ensure the connector and wiring are tidy, then clear any fault codes and verify the engine speed signal and starting performance. No special relearn is usually required on these engines.
