Parts for your 2017 Toyota Land cruiser-Crank angle sensor

2017 Toyota Land Cruiser crank-angle sensor: what it does and how to look after it

Based on Toyota technical literature—the Toyota Repair Manual on TIS, the New Car Features (NCF) guide for the 200 Series (covering both the 1VD‑FTV diesel and 3UR‑FE petrol engines), and the Electrical Wiring Diagram (EWD)—the 2017 Toyota Land Cruiser is fitted with a crank-angle sensor (Toyota usually calls it the crankshaft position sensor, providing the NE signal). The presence of standard OBD‑II diagnostics for P0335–P0339 in Toyota service information further confirms that this sensor is integral to the engine management on this model.

On the 2017 Land Cruiser, the crank-angle sensor monitors the exact speed and position of the crankshaft by reading a toothed reluctor wheel. That live signal lets the ECU time fuel injection and ignition precisely, and it also cross-checks with the camshaft sensor for engine synchronisation. Without a clean, accurate crank signal, starting becomes hit-and-miss, the idle can go rough, and the ECU may throw a warning light and drop the vehicle into limp mode.

This isn’t a regular replacement item, Toyota doesn’t specify routine renewal. As part of normal servicing, it’s smart to inspect the sensor connector and loom routing, especially where the harness runs close to the block and bellhousing. Look for oil intrusion, frayed insulation, or signs of heat damage. After spirited off‑road work or deep water crossings, checking for debris build‑up around the sensor mount is worthwhile.

If the Land Cruiser shows long cranking when warm, random stalling, a dead tachometer, or logged faults like P0335/P0336, attention to the crank-angle sensor and its wiring pays off. Replacement is straightforward for a trained tech: isolate the battery, access the sensor where it mounts to the engine, swap the unit with a quality OEM‑spec part, fit a fresh O‑ring, and reconnect. The ECU typically relearns automatically after a short drive cycle, just clear codes and verify crank and cam signals on a scan tool.

Owners who tow, tour long kilometres, or tackle corrugations should consider preventative checks at major services. Keeping connectors clean and secured, and avoiding direct pressure-washing under the bonnet, goes a long way. A healthy crank-angle sensor helps the big Cruiser start first hit, run smoothly, and keep fuel use in check across Aussie and Kiwi conditions.

• Common symptoms: hard starting, intermittent stalling, rough idle, misfire, poor economy, MIL on with P0335–P0339.
• Service tip: inspect wiring and connectors during each major service, replace only on fault, with OEM-spec components.

Popular questions about the 2017 Toyota Land Cruiser crank-angle sensor

Where is the crank-angle sensor located on a 2017 Land Cruiser?
The sensor is mounted on the engine and reads a reluctor on the crankshaft. Depending on engine variant, it’s positioned at the front cover or low on the block near the transmission end. Access can be tight, a workshop manual and proper lifting points make the job safer and quicker.

What are the tell‑tale signs the sensor is failing?
Typical clues include extended cranking, random cut‑outs when hot, no tach movement during cranking, and a check engine light. Scan tools often show P0335 or related codes. Before replacing the sensor, a quick check of the connector, O‑ring seepage, and wiring chafe is smart.

Does it need periodic replacement?
No scheduled interval is specified by Toyota. It’s replaced on condition. During regular servicing, technicians should inspect for damage and clean, secure connectors. After replacement, clearing codes and confirming stable crank and cam signals on a scan tool is recommended.
