2005 Toyota Camry camshaft sensor: fitted, what it does, and how to look after it

Referencing recognised technical sources, the 2005 Toyota Camry is fitted with a camshaft position sensor. Toyota’s factory Repair Manual for the 2002–2006 Camry (Engine Control – SFI and VVT‑i sections), the Toyota Electrical Wiring Diagram (EWD) for the same generation, and the Toyota Electronic Parts Catalogue all show a camshaft position sensor signal (commonly labelled “G”/“G2”) for the 2AZ‑FE 2.4‑litre four‑cylinder, and one sensor per bank on the 3MZ‑FE 3.3‑litre V6. These sensors work alongside the crankshaft sensor to manage sequential fuel injection, ignition timing, and VVT‑i cam timing.

For this Camry, the camshaft sensor is a small but critical bit of kit. It reads a toothed target on the cam to tell the engine control module exactly where the camshaft sits. That info lets the ECU fire each injector in sequence, time the spark properly, and command the VVT‑i system to advance or retard valve timing. When it’s healthy, starts are crisp, fuel economy stays tidy, and the idle is smooth as. When it’s not, the dash can light up with a check‑engine lamp, the car may crank longer cold, feel flat off the mark, or stumble at idle, and codes like P0340/P0341 may be stored.

Routine servicing doesn’t usually require replacement, but a quick check pays off, especially on higher‑kilometre cars:

• Location: on the cylinder head near the timing cover on the 2AZ‑FE, on the V6 there’s a sensor on each bank.
• Inspect the connector and wiring for heat brittleness, oil wicking, or green corrosion under the bonnet.
• Look for oil seeping past the sensor O‑ring, replace the O‑ring if there’s weeping.
• If removing, keep the area clean, lightly oil a new O‑ring, and refit the bolt to the factory torque spec noted in the repair manual.
• Use quality OEM‑equivalent (Denso/Toyota) sensors to avoid intermittent signals that cheap copies can cause.

Replacement is generally straightforward on the four‑cylinder: disconnect the negative battery terminal, unplug the connector, remove the retaining bolt, twist the sensor free, then reverse the steps with a new O‑ring. The V6 may need a bit more access time due to bank layout. After replacement, clearing fault codes and verifying live data cam/crank synchronisation with a scan tool is smart practice. Owners who notice hard starts, rough running, or poor fuel use should have the sensor and its wiring tested before throwing parts at it—often a tidy‑up of the connector or fixing a brittle loom does the trick. Kept dry, clean, and properly sealed, the Camry’s cam sensor typically lasts well past 200,000 kilometres.

Popular questions about the 2005 Toyota Camry camshaft sensor

Where is the camshaft sensor on a 2005 Camry?
On the 2.4‑litre 2AZ‑FE it’s mounted on the cylinder head near the timing chain end, close to the upper timing cover. On the 3.3‑litre V6 (3MZ‑FE) there’s one sensor per bank, positioned on each cylinder head. Access on the four‑cylinder is usually simple from the top, the V6 may need a few more bits moved for room.

What are common symptoms of a failing camshaft sensor?
Typical signs include long cranking, rough idle, flat spots, reduced fuel economy, and a check‑engine light with codes such as P0340 or P0341. In some cases the engine may stall intermittently when hot if the signal drops out.

Can it be cleaned or should it be replaced?
If the issue is minor oil contamination or a loose connector, a clean and reseat can restore a good signal. If the sensor’s internal electronics have degraded or the harness is damaged, replacement with an OEM‑quality part is the reliable fix. Always renew the O‑ring to prevent future oil leaks.
