2004 Toyota Land Cruiser Camshaft Sensor — What’s Fitted and What To Do

Based on Toyota’s factory documentation and parts catalogues, whether a camshaft position sensor is relevant on a 2004 Land Cruiser depends on the engine. The 4.7‑litre petrol V8 (2UZ‑FE) is built with a camshaft position sensor, shown in the Toyota Factory Service Manual (FSM) and the 2004 Electrical Wiring Diagram (EWD) as the “G”/cam sensor input used for sequential injection and ignition timing. By contrast, the 4.2‑litre turbo‑diesel (1HD‑FTE) doesn’t use a separate, external camshaft sensor, Toyota’s diesel engine control references indicate the ECU gets phase and speed information from the crank/TDC sensor and the electronically controlled injection pump’s internal NE/G signals, so a standalone cam sensor isn’t required.

For owners of the 1HD‑FTE: the reason there’s no dedicated camshaft sensor is the injection system architecture. The ECU already knows which stroke each cylinder is on using the crankshaft/TDC pickup and the pump’s own timing sensors, so a separate cam sensor would be redundant. That’s normal for this engine family and not a missing part.

If you’ve got the 2UZ‑FE V8 petrol, the camshaft sensor is a small but vital bit of the engine control system. Its job is to report camshaft position so the ECU can sync injection and spark to the correct stroke, sharpen cold starts, and keep emissions tidy. When it goes out of spec, you’ll usually notice hard starting, an occasional stumble or misfire, and the check‑engine light with codes like P0340 or P0345. Left to worsen, the ECU may fall back to less precise strategies, costing power and fuel.

On the 2UZ‑FE, the cam sensor sits at the front of a cylinder head near the timing belt cover. It’s not a scheduled replacement item, but it’s smart to inspect it during timing belt work (around 150,000 km) and any time the upper covers are off. Look for oil ingress at the O‑ring, brittle wiring, or a loose connector. If replacement’s needed, it’s a straightforward driveway job: disconnect the battery, unplug the connector, remove the single 10 mm hold‑down bolt, twist the sensor out, lightly oil the new O‑ring, refit and torque the bolt to about 8–10 N·m, reconnect and clear the codes. Most home mechanics will knock it over in half an hour.

A few practical tips for the V8:

• Go for an OE‑equivalent (Denso) sensor to avoid wonky signals or short service life.
• If you’re chasing intermittent faults, wiggle‑test the loom under the bonnet and check earths before blaming the sensor.
• After fitting, confirm live data sync with a scan tool and take a short test drive to verify no fresh fault codes return.

Treating the camshaft sensor as part of routine inspection — rather than waiting for a no‑start on a cold morning — keeps the 100 Series V8 feeling crisp and reliable for many more kilometres.

Popular questions about the 2004 Toyota Land Cruiser camshaft sensor

Where is the camshaft sensor on a 2004 Land Cruiser V8?
On the 2UZ‑FE petrol, it’s mounted at the front of the cylinder head near the timing belt cover (one bank), held by a single small bolt with a plug‑in connector. Access is typically from the top under the bonnet with basic hand tools.

What codes point to a failing camshaft sensor?
Common fault codes include P0340 (camshaft position sensor circuit) and, depending on bank and wiring, P0345. If these pop up with hard starting or a stumble, inspect the sensor, the O‑ring area for oil contamination, and the wiring/connector before replacing parts.

Does the 1HD‑FTE diesel have a camshaft sensor?
No separate camshaft sensor. The ECU uses the crank/TDC signal and the injection pump’s internal NE/G sensors to determine phase and timing, which is why you won’t find a standalone cam sensor on the HDJ100 diesel.
