Parts for your 2009 Toyota Land cruiser-Crank angle sensor

2009 Toyota Land Cruiser crank angle sensor

Yes, the 2009 Toyota Land Cruiser is fitted with a crank angle sensor (commonly called the crankshaft position sensor or CKP). Toyota’s technical literature identifies it as the NE signal sensor to the engine control module. This is detailed in the Toyota Land Cruiser 200 Series Repair Manual for the 1VD-FTV V8 diesel and 2UZ-FE petrol engines, including diagnostic entries for DTC P0335/P0339 (Crankshaft Position Sensor “A” Circuit). The Toyota New Car Features (NCF) manual for the 200 Series also explains the NE and G signals used for precise engine control, and the Toyota Electrical Wiring Diagram (EWD) shows the CKP sensor wired directly to the ECM. These factory sources confirm the sensor is relevant and standard on the 2009 model.

The crank angle sensor is the ECM’s timekeeper. It tracks crankshaft speed and position in real time so the ECM knows exactly when each cylinder is at top dead centre and how fast the engine is spinning. On the 200 Series, that signal is crucial for injection timing on the 1VD-FTV diesel and spark/injection timing on petrol variants. Without a clean NE signal, the engine won’t start or will run poorly because the ECM can’t accurately schedule fuel or ignition. It’s a small, solid-state sensor reading a toothed wheel on the crank, but it carries big responsibility for smooth starting, stable idle and strong, efficient pull under load.

Owners typically notice a crook crank sensor through hard starting, stalling when hot, misfires at low speed, or a sudden no-start with the check engine light on. Fault codes often logged include P0335 or P0339. Because the sensor sits near rotating hardware, it can be affected by metal fuzz or oil contamination, heat cycling, or wiring/connector damage under the bonnet. Left unchecked, a failing sensor can lead to increased fuel use, rough running and roadside grief.

There’s no set service interval, but it’s smart to include a quick visual during regular servicing: check the CKP harness and plug for chafing, oil seepage and loose pins. If replacement is needed, disconnect the battery, access the sensor (front timing cover on the V8 diesel, bellhousing area on some petrol variants), remove the retaining bolt, and ease the sensor out. Lightly oil the new O-ring, seat the new unit square, and torque the bolt to Toyota spec. Clear any stored codes and confirm a clean crank signal with a scan tool on live data. Genuine or quality OEM-equivalent parts are recommended to avoid signal noise and fitment dramas.

• Keep connectors clean and latched, moisture and green crust on pins cause intermittent faults.
• If the vehicle cranks but won’t fire and RPM reads zero on a scan tool, suspect the CKP first.
• After off-road or dusty work, inspect for debris build-up around the sensor area.

Where is the crank angle sensor on a 2009 Toyota Land Cruiser?

On the 1VD-FTV V8 diesel it’s typically mounted at the front of the engine on the timing cover reading a reluctor on the crank. On some petrol V8 variants, it’s positioned near the transmission bellhousing reading the drive plate. Access is usually from under the vehicle, a torch and a small ratchet make life easier.

What are the symptoms of a failing crank angle sensor on the 200 Series?

Common signs include a crank/no-start, stalling when hot, erratic tachometer behaviour, rough idle, or loss of power. The check engine light may appear with codes like P0335 or P0339. If live data shows zero RPM while cranking, the CKP or its wiring is a prime suspect.

Does the crank angle sensor need regular servicing or calibration?

No routine calibration is required. The best maintenance is preventative: keep the connector clean and secure, watch for oil leaks around the sensor, and inspect wiring after heavy off-road use. Replace the sensor if faults persist or if it shows internal damage or contamination.
