Parts for your 2022 Honda Cr-v-Knock sensor

2022 Honda CR‑V knock sensor — what it does and when to replace it

Referencing technical sources: the 2022 Honda CR‑V is fitted with a knock sensor. Honda’s 2017–2022 CR‑V Service Manual (Engine Controls, “Knock Sensor (KS)”) details diagnostics and DTCs P0325–P0330 for this component, and the Honda electronic parts catalogue for 2022 CR‑V (RW/RT chassis, 1.5‑litre VTEC Turbo and e:HEV 2.0) lists a block‑mounted knock sensor assembly used across these engines. Independent workshop databases such as ALLDATA and Mitchell also map the sensor in the engine wiring diagrams and test procedures, confirming it’s standard equipment.

On the 2022 Honda CR‑V, the knock sensor sits on the engine block (typically beneath the intake manifold), “listening” for abnormal combustion — that rattly ping known as knock. It sends a signal to the ECU so timing and, where applicable, boost can be trimmed on the fly. That protects the engine, keeps performance consistent, and helps fuel economy, especially when local petrol quality varies.

It’s not a routine service item. The sensor is solid‑state and generally lasts the life of the vehicle. Servicing is really about prevention: use good‑quality petrol, keep on top of scheduled services, and don’t ignore warning lights. If the ECU flags a fault (common codes are P0325–P0330) or there’s persistent pinging under load, the workshop will test the sensor circuit, wiring, and mounting torque before calling it faulty.

When replacement is genuinely required, it’s a straightforward but fiddly job due to access. A technician will let the engine cool, disconnect the battery, remove intake ducting or under‑covers as needed, unplug the connector, and swap the sensor. The sealing face on the block needs to be clean and dry, no sealant is used. Correct torque is important (Honda specifies roughly 22 N·m for late‑model knock sensors) so the sensor can “hear” accurately. The harness should be routed and clipped away from turbo and exhaust heat. After refitting, they’ll clear codes and perform any idle learn the ECU requests.

Signs that point to knock‑sensor or related issues include:

• Check Engine light with a KS‑related fault code (P0325–P0330)
• Noticeable pinging under load, dull performance, or increased fuel use
• Intermittent hesitation, especially climbing hills or towing

For most CR‑V owners in Australia and New Zealand, the best approach is simple: quality fuel, timely servicing, and prompt diagnosis if a light comes on. The sensor itself isn’t something that needs periodic attention, but it’s a small part doing a big job to keep the engine happy over hundreds of thousands of kilometres.

FAQs

Where is the knock sensor on a 2022 Honda CR‑V?
It’s mounted to the engine block, typically under the intake manifold near the middle cylinders. Access is often from above with intake components moved aside, or from underneath with the under‑tray off. A workshop manual view and a good torch make life easier.

What are common symptoms of a bad knock sensor on this model?
Most drivers will see a Check Engine light and feel slightly dull performance as the ECU plays it safe on ignition timing. There may be worse fuel use, occasional hesitation, or audible pinging under load. Proper diagnosis rules out wiring or connector corrosion before condemning the sensor.

Does the knock sensor need regular servicing?
No. It’s not a consumable. Focus on good‑quality petrol, maintaining cooling and ignition systems, and addressing fault codes promptly. If replacement is needed, correct torque and clean mounting are critical for accurate operation.
