2004 Toyota Kluger Camshaft Sensor — What It Does and How to Look After It

Technical sources confirm the 2004 Toyota Kluger does use a camshaft position sensor (CMP). The Toyota Repair Manual (TIS) for the Kluger/Highlander ACU20/MCU28 platforms describes CMP signal checks in the Engine Control (SFI) section, while the Toyota Electronic Parts Catalogue (EPC) lists a camshaft position sensor for the 2.4L 2AZ‑FE and the V6 engines (1MZ‑FE/3MZ‑FE). Independent service data (e.g., Haynes/Autodata) also reference CMP-related diagnostics and trouble codes for this model. So, yes—this part is absolutely relevant on the 2004 Kluger.

On this Kluger, the camshaft sensor tells the engine control module exactly where the camshaft is in its rotation. That timing info keeps sequential fuel injection spot-on and helps the VVT‑i system manage valve timing for smooth power, lower fuel use, and cleaner emissions. If the CMP signal goes walkabout, the ECM can’t line everything up properly—leading to hard starts, misfires, rough idle, or a stall. Common fault codes include P0340 (Bank 1) and P0345 (Bank 2 on V6).

It’s not a routine “replace-by-kilometres” item, but it does benefit from basic care during servicing:

• Keep oil leaks in check. Oil wicking into the connector can upset the signal.
• Inspect the wiring and plug for chafing, corrosion, or loose terminals.
• If removing the sensor, renew the O‑ring and seat it squarely to avoid leaks.

Replacement is straightforward for most home mechanics with a bit of patience. On the 2.4L four, the sensor sits at the end of the cylinder head near the timing chain end. On the V6, there’s one per cylinder bank. Usual steps are:

1. Safely disconnect the battery and unplug the sensor.
2. Remove the retaining bolt, ease the sensor out, and compare the old and new units.
3. Lightly oil the new O‑ring, install, and torque the bolt to factory spec.
4. Reconnect, clear any codes, and verify with a scan tool and road test.

If a new sensor doesn’t resolve the fault, dig deeper: check the crank sensor correlation, cam timing (especially if a timing belt/chain job was recent), and harness integrity. Given the Kluger’s age, brittle loom sections and tired connectors are increasingly common. When in doubt, genuine or high-quality OE-equivalent sensors tend to deliver the most reliable signal and fewer comebacks.

Popular questions

Does a 2004 Toyota Kluger have a camshaft sensor?
Yes. Toyota’s service manual, EPC, and mainstream service data all list and test the camshaft position sensor on 2AZ‑FE and V6 Kluger engines. The ECM relies on it for sequential injection and VVT‑i control.

Where is the camshaft sensor located on a 2004 Kluger?
On the 2.4L four it’s mounted on the cylinder head at the timing chain end. V6 models have one sensor per cylinder bank, positioned at the ends of the heads near the cam drive. Access varies—front bank is easier than the rear on V6.

Is it safe to drive with a failing camshaft sensor?
It might run, but it can be hard to start, misfire, or stall, and may trigger limp behaviour. Driving like that risks poor fuel economy and potential catalyst damage. Best to diagnose and repair promptly.
