Parts for your 2010 Toyota Camry-Camshaft sensor

2010 Toyota Camry camshaft sensor — what it does and when to sort it

Per Toyota technical sources, the 2010 Camry does use a camshaft position sensor. The Toyota Repair Manual for the 2AR‑FE (2.5‑litre) and 2GR‑FE (3.5‑litre V6) engines lists the Camshaft Position Sensor (CMP) in the SFI/engine control section and provides related DTCs such as P0340/P0341 (and P0345/P0349 for the V6). Toyota’s Electronic Parts Catalogue and the Electrical Wiring Diagram also show the CMP sensor circuit and connectors. So, it’s absolutely relevant on this model year.

On a 2010 Camry, the camshaft sensor tells the engine ECU exactly where the camshaft is in its rotation. That info is used for spark timing, fuel injection timing, and to manage Dual VVT‑i. If the signal goes missing or skew-whiff, the engine can crank longer, idle roughly, hesitate on take-off, or log a check engine light. The four‑cylinder uses at least one CMP on the cylinder head, the V6 has one per bank.

This isn’t a scheduled service item, but it’s worth a look during major services, especially if there’ve been oil leaks up top. Oil intrusion into the connector or a brittle harness can upset the signal. Keeping clean, correct‑grade engine oil and timely changes helps the sensor read a clean reluctor pattern and keeps VVT gear operation smooth, which the ECU correlates with CMP data.

• Common symptoms of a crook CMP: hard starting, misfire at idle, poor fuel economy, limp mode, and DTCs like P0340/P0341 (I4) or P0345/P0349 (V6).
• Quick checks: inspect the plug for oil, bent pins, or green corrosion, verify harness strain relief, confirm no confusion with the nearby VVT oil control valve.

Replacement is straightforward for a competent DIYer, but most owners will prefer a workshop. Under the bonnet, the sensor sits on the cylinder head near the cam gear. Disconnect the battery, unplug the connector, remove the retaining bolt, and ease the sensor out—there’s an O‑ring that may hang on. Lightly oil the new O‑ring, seat the sensor squarely, and tighten the bolt to the factory spec noted in the Toyota Repair Manual. Clear codes, start the car, and check live data for a clean cam signal. On the V6, if one bank’s sensor fails, best practice is to test both banks—replace only what tests faulty unless a matched pair is advised after diagnosis.

Use quality parts that meet OE spec, as cheap copies can cause intermittent faults that’ll drive anyone spare. If in doubt, a scan and scope check by a technician will confirm the sensor’s health without guesswork.

Popular questions

Where is the camshaft sensor on a 2010 Toyota Camry?
On the four‑cylinder 2AR‑FE, it’s mounted on the cylinder head near the timing cover, typically at the intake cam end. On the 2GR‑FE V6 there’s one sensor on each bank, accessible near the front and rear cylinder heads. Access may require removing engine covers and unplugging nearby looms for room.

Can a faulty camshaft sensor damage the engine?
It usually won’t cause immediate mechanical damage, but it can trigger hard starting, misfires, and poor economy. Left unfixed, repeated misfires and unburnt fuel can stress the catalytic converter. Best to diagnose promptly if the check engine light and relevant DTCs appear.

Do both camshaft sensors need replacing on the V6?
Not automatically. The smart move is to diagnose both banks and the wiring. Replace the faulty unit, verify the fix, and only replace the other if testing shows issues or if a technician recommends pairing based on age and condition.
