2005 Toyota Caldina Camshaft Sensor — What it does and how to look after it

Based on Toyota technical literature, the 2005 Toyota Caldina does use a camshaft position sensor. Toyota’s TIS Repair Manual for the Caldina T24# series (covering 1ZZ‑FE and 3S‑GTE engines) describes the Camshaft Position Sensor (often labelled “G2”) as an input for fuel injection, ignition timing and VVT‑i control. The 2005 Caldina Electrical Wiring Diagram shows a dedicated “Camshaft Position Sensor” circuit, and Toyota’s Electronic Parts Catalogue lists a camshaft sensor for these engines (e.g., 90919‑05024 for 1ZZ‑FE, variants apply to 3S‑GTE). These sources confirm the part is fitted and relevant on the 2005 Caldina.

On this model, the camshaft sensor keeps the ECU in the loop about the exact position and phase of the camshaft. That intel lets the car run true sequential fuel injection, dial in precise spark timing, and command VVT‑i so it pulls cleanly across the rev range. Under the bonnet, you’ll typically find the sensor on the cylinder head near the timing chain/belt end: on the 1ZZ‑FE, it’s at the intake cam side by the chain, while on the GT‑Four’s 3S‑GTE it sits near the cam gear under the top cover.

It’s a low‑maintenance bit of kit, but it does live in heat and oil vapour. As part of regular servicing, it’s smart to:

• Inspect the connector and wiring for brittleness, oil intrusion or green corrosion.
• Check for cam cover oil leaks that can wick into the plug.
• Keep engine oil clean, sludgy oil can upset VVT‑i and, by extension, the sensor’s signal quality.

Typical fault signs include hard starting, rough idle, sudden stalls, dead spots on acceleration, increased fuel use, and the MIL on with codes like P0340/P0341 (and sometimes VVT‑i correlation codes). If testing confirms the sensor has packed it in, replacement is straightforward: disconnect the battery, unplug the sensor, remove the retaining bolt, twist the sensor free, lightly oil the new O‑ring, refit and torque the bolt to about 9–10 N·m (check the exact spec in the Toyota manual), reconnect and clear codes. No special relearn is usually needed, the ECU picks it up on the next start.

Quality matters here. A genuine Toyota or Denso sensor will typically give the cleanest signal and best longevity. If a fault persists after replacement, double‑check the harness back to the ECU and confirm the crank sensor and timing are spot on, as the ECU uses both cam and crank signals together.

Popular questions about 2005 Toyota Caldina camshaft sensors

Where is the camshaft sensor located on a 2005 Caldina?
It’s mounted on the cylinder head at the timing end. On 1ZZ‑FE cars it sits by the intake cam near the timing chain. On 3S‑GTE GT‑Four models it’s near the cam sprocket under the upper cover. Look for a small, single‑bolt sensor with a two‑ or three‑pin plug.

What fault codes point to a bad camshaft sensor on this model?
Common codes include P0340 and P0341 for the camshaft position circuit or range/performance. You might also see VVT‑i correlation codes if the ECU can’t reconcile cam and crank signals. Always rule out wiring damage, oil in the connector and poor grounds before condemning the sensor.

Can it be driven with a faulty camshaft sensor?
Sometimes the ECU falls back to a limp strategy using the crank signal, but starting can be hit‑and‑miss and performance will drop. It’s not ideal for long trips around Aotearoa/NZ or across Aussie distances—best to repair promptly to avoid stalling or further issues.
