2013 Toyota Crown Knock Sensor — Purpose and Service Advice

Technical sources confirm the 2013 Toyota Crown is fitted with knock sensors. Toyota’s service information for the S210 Crown (2013–2018) details a “Sensor, Knock Control” within the engine control system for the 4GR-FSE and 2GR-FSE V6s and the 2AR-FSE hybrid four. Toyota’s Electronic Parts Catalogue (EPC) also lists one knock sensor for the 2AR-FSE and two sensors for the V6s (one per bank in the V-engine valley). These factory references establish that the knock sensor is both relevant and used on the 2013 Toyota Crown.

On this Crown, the knock sensor’s job is to listen for abnormal combustion (knock/ping) and let the ECU trim ignition timing to protect the engine and keep it running smoothly on everyday Aussie and Kiwi fuels. It’s a small, Denso-style piezoelectric microphone bolted to the block, when it hears knock, timing is pulled back just enough to stop the rattle without killing performance or economy.

It’s not a high-maintenance item, but it does deserve attention during routine servicing. On V6 models (4GR-FSE/2GR-FSE), the sensors sit under the intake manifold in the valley, so they’re easiest to inspect or replace when the manifold is already off for other jobs. The 2AR-FSE inline-four typically has a single sensor on the block, accessible with far less disassembly. Always refit with the factory torque spec (over-tightening or cocked installation can make the sensor deaf, under-tightening can make it overreact). Genuine or OEM-quality sensors and a clean, dry seating surface are the go.

• Typical signs it’s time to check the knock sensor or wiring:
  • Engine pinging under load, lazy performance, higher fuel use
  • Check Engine Light with codes like P0325–P0334
  • Intermittent faults after coolant or oil leaks into the valley
• Good servicing tips:
  • Inspect the connector and harness for brittle insulation or corrosion
  • Use a torque wrench, don’t add grease between sensor and block
  • If codes persist, verify with live data and a proper road test under load

Replacement timing is condition-based rather than kilometre-based. If the ECU is pulling heaps of timing or logging knock sensor faults, and other causes (poor fuel, vacuum leaks, carbon buildup) are ruled out, a new sensor and fresh harness clip usually restore proper knock control. After refitting, clear codes and let the ECU relearn with a few varied-drive cycles.

Does the 2013 Toyota Crown have a knock sensor and where is it?

Yes. The 2AR-FSE hybrid four normally has one on the block. The 4GR-FSE and 2GR-FSE V6s have two, mounted in the engine valley—one per bank beneath the intake manifold. Access on the V6s usually requires manifold removal.

What fault codes point to a bad knock sensor on a 2013 Crown?

Common codes include P0325, P0327, P0328, P0330, P0332 and P0333. Before condemning the sensor, check fuel quality, look for intake or vacuum leaks, and inspect the wiring and connector. If the sensor is cracked, contaminated, or out of torque, replacement is sensible.

How much does replacement typically cost?

On the 2AR-FSE, parts and labour are generally modest because access is easier. On V6 models, labour is higher due to intake manifold removal—think a few hours’ workshop time. Many owners prefer OEM Toyota/Denso sensors for reliability, even if they cost a bit more.
