Parts for your 2009 Toyota Land cruiser-Camshaft sensor

2009 Toyota Land Cruiser camshaft sensor — purpose, care, and replacement

Based on Toyota’s own technical literature, the 2009 Land Cruiser (200 Series) does use camshaft position sensors. The Toyota Land Cruiser 200 Series Repair Manual (Engine Control System sections for 1VD‑FTV diesel and UR/UZ petrol V8s), the Land Cruiser 200 Electrical Wiring Diagram (EWD, 2008–2011), and the New Car Features (NCF) manuals all identify camshaft position sensors (often labelled “G” or “G2” signals) and related DTCs such as P0340/P0345. On the V8 engines fitted to this model year, there’s one sensor per bank.

On a 2009 Land Cruiser, the camshaft sensor provides the ECU with precise camshaft phase information so it can sync fuel injection and ignition timing, and manage variable valve timing. Pairing the cam signal with the crank signal lets the engine fire sequentially, start quickly, and run smoothly under all loads. When the sensor signal is missing or erratic, the ECU may drop into a backup strategy, causing hard starts, rough idle, sluggish performance, increased fuel use, and stored fault codes.

• Typical symptoms of a failing sensor: extended cranking, misfires at idle, poor throttle response, higher fuel consumption, and DTCs like P0340/P0345/P0365/P0390.
• Location: at the front of each cylinder head near the timing cover (V8 = Bank 1 and Bank 2).

Replacement isn’t a regular service item, but it’s straightforward if needed. Always confirm with scan data and wiring checks first, as damaged connectors or harness chafing can mimic a bad sensor.

1. Disconnect the battery and remove engine covers for access.
2. Unplug the sensor and remove its retaining bolt.
3. Withdraw the sensor, noting the O‑ring. Lightly oil a new O‑ring and install the replacement.
4. Refit the bolt and torque to workshop spec, reconnect the plug, and clear codes with a scan tool.

Good servicing practice on these Land Cruisers is to keep engine oil and filters changed on schedule, clean oil helps maintain a crisp cam signal and stable VVT operation. During routine services, a quick visual over the sensor area for oil leaks, cracked connectors, or rubbed wiring under the bonnet can head off intermittent faults. If moisture or oil is found inside the connector, repair the source of the leak before condemning the sensor. Use genuine or high‑quality aftermarket parts and avoid mixing up left and right bank sensors when both are removed.

Does a 2009 Land Cruiser have more than one camshaft sensor?

Yes. The V8 engines used in 2009 models have a camshaft sensor on each bank. If one fails, the ECU will usually log a bank‑specific code (for example P0345 for Bank 2), which helps with diagnosis and pin‑pointing the faulty side.

What’s the best way to tell if the camshaft sensor is the real problem?

Scan for DTCs and view live data for cam/crank synchronisation. Inspect the connector and loom for oil ingress or damage, and verify power/ground/signal with a multimeter or scope. Only replace the sensor after these checks, as wiring issues are common look‑alikes.

Is a camshaft sensor a service item on a 2009 Land Cruiser?

No, it’s not scheduled maintenance. However, it’s smart to inspect it during routine services, especially for oil leaks at the O‑ring and harness rubbing. Timely oil changes go a long way to keeping the sensor and VVT system happy.
