2020 Toyota Camry camshaft sensor: what it does and how to look after it

Yes, the 2020 Toyota Camry does use a camshaft position sensor (often two on the 2.5‑litre, and two per bank on the 3.5‑litre V6). This is confirmed by Toyota’s 2020 Camry Repair Manual content in TIS (Engine/Hybrid System – SFI System – Camshaft Position Sensor), Toyota’s Electronic Parts Catalogue listings for “Sensor, Cam Position” against A25A‑FKS/FXS and 2GR‑FKS engines, and the supported OBD‑II diagnostic trouble codes such as P0340/P0345 for this model year. Those technical sources make it clear the sensor is fitted and used by the engine ECU.

The camshaft sensor’s job is to tell the ECU exactly where each cam is in its rotation. On the 2020 Camry’s dual VVT-i/VVT‑iE engines, that signal is crucial for precise fuel injection timing, spark timing, and variable valve timing control. With clean, accurate cam timing data, the ECU can deliver smooth starts, crisp response, better fuel economy and low emissions. If the signal is erratic or missing, the Camry may crank longer, run roughly, drop into limp mode, or log a check engine light with a cam/crank correlation fault.

There’s no scheduled replacement for the camshaft sensor, it’s a solid-state Hall device designed to last the life of the car. As part of routine servicing, it’s worth a quick visual check for oil contamination at the sensor bore, brittle wiring near the cylinder head, and connector pin fitment. A light film of clean engine oil on the O‑ring helps prevent future sealing issues if the sensor’s been out for inspection.

If replacement’s needed, it’s a straightforward job for most technicians. Common pointers include:

• Confirm the fault with a scan and a scope test if available, rule out harness damage first.
• Match the sensor to the engine variant (2.5L or 3.5L) and bank/intake–exhaust position.
• Fit quality OEM-equivalent parts, cheap sensors often cause repeat faults.
• Lightly oil the new O‑ring, seat the sensor squarely, and tighten to the workshop spec.
• Clear codes and perform a road test, most Camrys don’t require a special relearn.

Typical warning signs owners notice include hard starting, intermittent stalling at idle, poor fuel economy, sluggish acceleration, and the MIL on. Left unchecked, a failing sensor can make the Camry unpleasant to drive and may strand the driver, so it’s sensible to sort it promptly.

FAQs

Where is the camshaft sensor on a 2020 Toyota Camry?
On the 2.5‑litre four‑cylinder, camshaft sensors sit on the cylinder head near the timing chain end, typically one reading the intake cam and one the exhaust cam. On the 3.5‑litre V6, there’s a sensor for each bank (and typically for each cam). They’re usually accessible from the top with basic hand tools.

How often should the camshaft sensor be replaced?
There’s no set interval. It’s replaced on condition—when diagnostics point to a failed sensor or wiring issue, or if codes like P0340/P0345 return after checks. During regular servicing, a quick inspection for oil leaks and connector condition is ample.

Can you keep driving with a faulty camshaft sensor?
It may start and run, but it can stall, hesitate, or drop power unpredictably. The ECU may use a fallback strategy, but it’s not ideal and could leave the driver stranded. Best practice is to have it diagnosed and repaired sooner rather than later.
