Parts for your 2005 Toyota Kluger-Camshaft sensor

2005 Toyota Kluger Camshaft Position Sensor

It is relevant and fitted. Toyota’s own technical literature confirms the 2005 Toyota Kluger (XU20 platform) uses a camshaft position sensor (CMP). The Toyota Repair Manual for Highlander/Kluger (covering the 2AZ‑FE 2.4‑litre and 3MZ‑FE 3.3‑litre V6) shows a CMP sensor used for sequential fuel injection and VVT‑i control, with diagnostic references to DTCs such as P0340 (Camshaft Position Sensor “A” Circuit) and, on the V6, P0345 (Camshaft Position Sensor “A” Circuit Bank 2). Toyota’s Electronic Parts Catalogue also lists a camshaft sensor for both the 4‑cylinder and V6 variants, with the V6 having one per bank.

The camshaft position sensor on a 2005 Kluger tells the engine control module exactly where the camshafts are in their rotation. That lets the ECU fire the injectors at the right moment and manage VVT‑i to keep power, emissions and fuel use on song. On the 2AZ‑FE, the sensor sits at the timing chain end of the cylinder head. On the 3MZ‑FE, there’s a sensor on each bank near the cam covers.

As a solid‑state Hall or magnetic pickup, the sensor itself doesn’t wear like a moving part, but heat, oil contamination, or wiring issues can knock it about. Common tell‑tales include:

• Hard starting or no‑start when hot or cold
• Rough idle, hesitation, or stalling
• Poor fuel economy and reduced performance
• Check Engine Light with codes like P0340/P0345

There’s no fixed service interval for a CMP sensor, it’s a replace‑on‑failure item. That said, good servicing helps: regular oil changes keep VVT‑i happy, which prevents cam/crank correlation dramas that can be mistaken for a sensor fault. During routine services, a quick look under the bonnet to check the sensor connector for oil wicking, broken clips, or chafed wiring near the timing cover is time well spent.

Replacement is straightforward for a competent home mechanic or workshop: disconnect the battery, unplug the sensor, remove the small retaining bolt, and pull the sensor free. Always fit a new O‑ring, lightly oil it, and seat the sensor cleanly before tightening the bolt to the factory spec. Use a quality, OE‑spec sensor to avoid intermittent signals. After installation, clear any stored codes and perform a road test, if the fault returns, inspect harness integrity and confirm cam/crank signals with a scope as the Toyota repair manual suggests.

Do all 2005 Toyota Klugers have a camshaft sensor?

Yes. Both engine options used in the 2005 Kluger—the 2.4‑litre 2AZ‑FE and the 3.3‑litre 3MZ‑FE V6—are equipped with camshaft position sensing as documented in Toyota repair manuals and parts catalogues. The V6 uses one sensor per bank.

What are the symptoms of a failing camshaft sensor on a 2005 Kluger?

Owners often notice hard starting, rough idle, hesitation, or stalling, plus a Check Engine Light. Typical diagnostic trouble codes include P0340 and, on V6 models, P0345. Fuel economy and performance can also drop off when the signal is erratic.

Can a home mechanic replace the camshaft sensor on a 2005 Kluger?

Generally, yes. Access is decent, and it’s usually a single bolt and an electrical connector. Fit a new O‑ring, keep the area clean, and don’t overtighten the bolt. If issues persist after replacement, a wiring check and signal test per the Toyota repair manual is the next step.
