2024 Toyota Camry Knock Sensor: What it does and when to service it

Based on Toyota New Car Features for the AXVH70-series Camry and the Toyota Repair Manual for the A25A-FKS/FXS Dynamic Force engines (which list a flat-type piezoelectric knock control sensor and diagnostic trouble codes such as P0325/P0328), the 2024 Toyota Camry—Hybrid included—does use a knock sensor. These factory sources describe the ECU’s knock control strategy and the sensor’s mounting to the cylinder block, confirming it’s a fitted and relevant component.

For owners, the knock sensor is one of those quiet achievers. It “listens” for combustion knock (pinging) through vibrations in the engine block and lets the engine control unit trim ignition timing on the fly. That means smooth running on Aussie and Kiwi pump fuels (91–95 RON), better efficiency, and proper protection when it’s hot, under load, or when fuel quality varies. In short, it helps the Camry deliver its claimed power and economy without risking piston or bearing damage from detonation.

There’s no scheduled replacement interval for the knock sensor on a 2024 Camry, but it’s worth a look any time the intake side is off or during bigger jobs. Owners and workshops typically keep an eye out for:

• Check engine light with codes like P0325/P0328
• Noticeable pinging under load, sluggish performance, or higher fuel use
• Intermittent hesitation, especially on hills or when towing

If symptoms or codes pop up, rule out basics first: correct fuel, no obvious misfires, no intake leaks, and clean engine earths. Then check the knock sensor harness and connector for damage or oil intrusion. The sensor relies on a clean, flat mating surface and the correct torque to transmit vibration accurately—over-tightening, under-tightening, or corrosion can upset readings. Replacement is straightforward for a trained tech: disconnect the battery, gain access (usually under the intake area on the inline-four), remove the old sensor, clean the block face, fit a genuine or high-quality OE-equivalent sensor with a new connector seal if required, and torque exactly to the workshop spec.

Because the sensor is tuned to the Camry’s engine acoustics, sticking with genuine or OE-quality parts is smart. After fitting, clear codes and road test under load to confirm the ECU learns cleanly with no return faults. Treated right, the knock sensor will quietly keep the Camry’s engine happy for many kilometres.

Does the 2024 Camry Hybrid have a knock sensor?

Yes. Toyota’s Dynamic Force 2.5-litre hybrid engine uses a flat-type knock sensor mounted to the cylinder block. It feeds vibration data to the ECU so timing can be adjusted to prevent pinging and maintain smooth, efficient running on local petrol grades.

What are the signs of a bad knock sensor on a 2024 Camry?

Common clues include a check engine light (often P0325/P0328), dull performance, worse fuel economy, or audible pinging under load. It can feel like the car’s lost its edge on hills. Always confirm with a scan and basic checks before replacing the sensor.

Is it safe to drive with a P0325 knock sensor code?

The ECU will usually pull timing to protect the engine, so the car may feel flat. Short trips to a workshop are generally fine, but extended driving isn’t ideal. Get it inspected promptly to avoid potential knock-related engine damage and restore normal performance.
