Parts for your 2005 Toyota Land cruiser-Crank angle sensor

2005 Toyota Land Cruiser crank angle sensor

Based on Toyota factory information for the 100 Series (UZJ100/HDJ100/HZJ105), including the Toyota repair manuals, the Electrical Wiring Diagram (EWD) and the Toyota Electronic Parts Catalogue (EPC), a crank angle sensor (crankshaft position sensor) is fitted to 2005 Land Cruiser models with electronic engine management — notably the 2UZ‑FE 4.7‑litre V8 petrol and the 1HD‑FTE 4.2‑litre turbo‑diesel. The mechanically injected 1HZ 4.2‑litre diesel (HZJ105) is not equipped with a crank angle sensor because its fuel timing and ignition needs aren’t ECU‑controlled.

On vehicles that have it, the crank angle sensor is the ECU’s primary timing reference. It monitors a toothed wheel on the crank, letting the ECU pinpoint piston position and engine speed so it can fire the coils and injectors right on cue. That precise timing delivers smooth starts, good fuel economy, strong torque, and clean emissions — exactly what owners expect from a well‑sorted 100 Series.

During routine servicing, the sensor itself isn’t a scheduled replacement item, but a quick visual once‑over pays dividends. It lives low on the front of the engine (2UZ‑FE: near the lower timing cover/crank pulley, 1HD‑FTE: at the timing gear case), so it can cop oil mist, dust, or the odd splash. Check the connector for corrosion, make sure the wiring sheath hasn’t chafed through, and keep an eye out for oil leaks that could contaminate the tip.

If the Land Cruiser is slow to start when hot or cold, randomly stalls, or throws a check‑engine light, the crank angle sensor and its wiring are worth testing. Common fault codes include P0335 and P0336. Always rule out basics first — battery health, earths, and harness integrity — before condemning the sensor.

• Tell‑tale symptoms: hard starting, intermittent no‑start, sudden cut‑out, misfire at certain revs, and erratic tacho behaviour on EFI models.
• Good practice: use an OEM‑quality sensor, inspect the connector pins, route the loom away from heat and sharp edges, and clear any stored DTCs after replacement.
• Fitting notes: disconnect the battery, allow the engine to cool, and work from under the front with proper support. Lightly oil the O‑ring (if fitted), seat the sensor squarely, and tighten to the specification in the Toyota repair manual for your exact engine.

No special programming is normally required after replacement on these Toyotas, the ECU relearns on the fly. If it’s a 1HZ mechanical‑pump model, there’s no crank angle sensor to service — engine timing is set mechanically, and the tacho signal is sourced differently, which is why that engine gets by without a CKP.

Popular questions about the 2005 Toyota Land Cruiser crank angle sensor

Where is the crank angle sensor located?
On the 2UZ‑FE V8 it’s mounted at the lower front of the engine near the crank pulley/timing cover. On the 1HD‑FTE diesel it’s fitted to the timing gear case. The 1HZ mechanical‑pump engine isn’t fitted with a crank angle sensor.

What fault codes point to a bad crank angle sensor?
Typical codes are P0335 (Crankshaft Position Sensor “A” Circuit) and P0336 (Crankshaft Position Sensor Range/Performance). These may come with symptoms like hard starting, intermittent stall, or loss of power. Always inspect the wiring and connector before replacing the sensor.

Does a new sensor need programming?
No special programming is usually required. After installation, clear any stored codes and take the vehicle for a drive so the ECU can settle its trims. If codes return, recheck the sensor air gap (where applicable), the loom routing, earths, and the ECU power/ground supplies.
