Parts for your 2016 Toyota Crown-Knock sensor

2016 Toyota Crown knock sensor

Technical sources confirm the 2016 Toyota Crown does use a knock sensor. Toyota’s service literature for the S210-series Crown (TIS workshop manual and engine diagnostics) lists knock sensor–related DTCs (such as P0325–P0330) and shows the sensor in the wiring diagrams. The Toyota Electronic Parts Catalogue (EPC) for S210 variants (e.g., 8AR-FTS 2.0 turbo, 2AR-FSE 2.5 hybrid, and 2GR-FSE 3.5 V6) also lists a “Sensor, Knock Control,” with one sensor on the four-cylinder engines and two sensors on the V6. Factory engine repair manuals for the 2GR-FSE show the twin-sensor arrangement in the V of the block beneath the intake manifold. So, it’s a relevant, fitted component on the 2016 Crown.

On the 2016 Toyota Crown, the knock sensor’s job is to listen for the specific vibration that signals detonation (knock). When it picks up that telltale ping, the engine ECU trims ignition timing and, if needed, fuelling or boost (on the 8AR-FTS turbo) to keep things smooth and safe. That means better reliability, cleaner running, and the best possible performance on the fuel in the tank—handy across Aussie and Kiwi octane options.

There’s no scheduled replacement for the knock sensor, but it’s smart to give it some love during servicing. A quick check of the sensor harness and connector for heat-hardening, oil contamination, or chafing can prevent dramas later. If the dash shows a Check Engine light and a scan tool logs knock sensor faults (think P0325 to P0330), or there’s rattly “pinging,” lazy performance, or higher fuel use, the sensor or its wiring could be the culprit.

Replacement is straightforward on the four-cylinder engines (mounted to the block, typically under the intake side), and more involved on the 2GR-FSE V6 because both sensors sit in the valley under the intake manifold. If the manifold’s coming off on the V6, many techs replace both sensors together and inspect the sub-loom while they’re in there. Use a quality, OEM-spec sensor, clean the mounting pad, and tighten to the factory torque (around 20 N·m—confirm for your engine code). After fitting, clear codes and perform any knock-learn or idle relearn the service manual specifies.

• Tips for longevity: use the recommended fuel grade, keep the cooling system healthy, and fix intake or exhaust leaks promptly—these all help the ECU trust what the knock sensor hears.

Popular questions about 2016 Toyota Crown knock sensors

Where is the knock sensor on a 2016 Crown?
On the 8AR-FTS and 2AR-FSE four-cyl engines, it’s bolted to the block on the intake side, below the manifold area. On the 2GR-FSE V6, there are two sensors in the valley under the intake manifold. Access on the V6 usually requires removing the manifold.

Can it be driven with a faulty knock sensor?
The ECU will usually pull timing to protect the engine, so it may feel down on power and use more fuel. Driving for long periods isn’t wise—if detonation isn’t detected or controlled properly, internal engine damage can result. Best to diagnose and repair promptly.

Should both knock sensors be replaced on the V6?
If one has failed and the intake manifold is off, many workshops replace both sensors and inspect or renew the harness. It saves future labour and helps ensure consistent knock detection across both banks.
