2005 Toyota Land Cruiser camshaft sensor — what it does and when to replace it

Relevant factory documentation confirms the 2005 Toyota Land Cruiser uses a camshaft position sensor. The Toyota Factory Service Manual for the 100 Series (2UZ‑FE petrol) details Camshaft Position Sensor RH/LH items and related DTCs P0340/P0345, and the 2005 Electrical Wiring Diagram shows the “G”/“G2” cam signals for each bank. For diesel variants (1HD‑FTE), Toyota’s engine control system documentation specifies a cam timing reference input (labelled as a camshaft position signal) used by the ECM to synchronise injection. So the camshaft sensor is very much part of the 2005 Land Cruiser’s engine management across petrol and diesel models.

On the ’05 Land Cruiser, the camshaft sensor tells the engine computer exactly where the cam(s) are in their rotation. That lets the ECM fire injectors sequentially, time ignition precisely (on the V8), and control variable valve timing on the later 2UZ‑FE VVT‑i engines. On the 1HD‑FTE turbo‑diesel, the camshaft position input helps the ECM line up injection events with top‑dead‑centre. If that signal goes missing or dodgy, expect hard starts, misfires, poor fuel economy, a flat spot under load, or the odd stall. The check engine lamp will usually flag codes like P0340/P0345 (petrol) or related cam correlation faults.

There’s no routine “service” for the sensor itself, but it’s smart to give it some love at timing belt time. For both 2UZ‑FE and 1HD‑FTE, the timing belt interval is a handy moment to inspect the sensor bodies, O‑rings, and the nearby wiring looms for oil seepage, brittle insulation, or loose connectors. Oil leaks from rocker covers can wick down to the sensor plug and cause intermittent signals, so fixing minor leaks pays off.

Replacement is straightforward for a competent DIYer or any workshop:

• Disconnect the battery and unplug the sensor connector.
• Remove the retaining bolt, withdraw the sensor, and compare the new part’s O‑ring and connector keying.
• Lightly oil the O‑ring, install, and tighten to the workshop manual spec.
• Clear codes and confirm cam/crank sync with a scan tool during a warm idle and a brief road test.

On the V8, there are two sensors (one per bank). If the vehicle has racked up big kilometres and one fails, many techs choose to replace both so the signal quality is matched. Use genuine or reputable OE‑equivalent parts, bargain‑bin sensors can cause annoying intermittent faults that are tougher to chase than the original issue.

Where is the camshaft sensor on a 2005 Land Cruiser?
On the 2UZ‑FE V8, there are two sensors mounted near the front of each cylinder head by the timing cover—Bank 1 (right) and Bank 2 (left). On the 1HD‑FTE diesel, the cam timing sensor is positioned at the front of the head/timing case area where it can read the cam reference. Access varies with accessories and snorkels fitted, but it’s typically reachable from above with basic tools.

What symptoms point to a failing camshaft sensor on a 100 Series?
Common signs include extended cranking, random stumbles, a sudden loss of power under load, and the check engine light with cam sensor or correlation codes. Fuel economy can drop and the exhaust note may sound off. On VVT‑i V8s, roughness at certain revs can show up because the ECM can’t target valve timing properly without a clean cam signal.

Is it safe to drive with a bad camshaft sensor?
It might still run, but it’s not wise. The ECM may fall back to a less efficient strategy, which can mean poor performance, higher fuel use, or even stalling at the worst time. There’s also the risk of masking other faults. It’s better to diagnose promptly, fix any wiring issues, and replace the sensor if it’s out of spec.
