Parts for your 2016 Toyota Camry-Knock sensor

2016 Toyota Camry Knock Sensor — What it does and when to sort it

Yes, a knock sensor is fitted to the 2016 Toyota Camry. Technical sources including Toyota’s Service Information (TIS) for the 2015–2017 Camry list diagnostic trouble codes P0325 (Knock Sensor Circuit Bank 1) and P0330 (Bank 2 for V6), confirming the sensor’s presence and monitoring by the ECM. The Toyota repair manual sections for the 2AR‑FE/2AR‑FXE four‑cylinder and 2GR‑FE V6 engines include knock sensor testing and replacement procedures. Aftermarket workshop guides for 2007–2017 Camry models also specify the sensor’s location and torque, reinforcing that it’s a standard part of the engine management.

On the 2.5‑litre four‑cylinder, there’s a single knock sensor mounted on the block under the intake side. On the 3.5‑litre V6, there are two sensors tucked in the “valley” beneath the intake manifold. The sensor listens for high‑frequency vibration (pinging) and lets the ECU trim ignition timing to protect the engine while keeping performance and efficiency on song.

As part of servicing, the knock sensor isn’t a regular replacement item, but it pays to keep an eye on symptoms that suggest trouble:

• Check engine light with codes P0325/P0330
• Audible pinging under load, sluggish performance, or higher fuel use
• Intermittent misfire feel when the ECU pulls timing to stay safe

Replacement advice for a 2016 Camry:

1. Confirm the fault with proper diagnostics (scan data such as knock correction/learned values) before replacing parts.
2. Inspect the harness and connector first—heat and oil can harden wiring near the block.
3. Use genuine‑spec sensors and a torque wrench. Over‑ or under‑torque can skew sensitivity.
4. Be ready to remove the intake manifold on both engines for access, the V6 requires upper intake/plenum removal to reach the valley. Have new gaskets on hand.
5. Keep the mating surface clean and dry, don’t use sealants on the sensor seat.

Good fuel quality helps reduce knock events, and fixing oil or coolant leaks near the intake side prevents contamination of the connector. If the car throws a knock sensor code and goes a bit flat, it’s the ECU protecting the engine—safe to limp home, but book it in sooner rather than later.

Popular questions about 2016 Toyota Camry knock sensors

Does a 2016 Camry have a knock sensor?

It does. Four‑cylinder models use one sensor on the intake side of the block, while V6 models run two sensors under the intake manifold in the valley. Toyota’s factory diagnostics include codes P0325 and P0330 specifically for these circuits.

Where is the knock sensor located on a 2016 Camry?

On the 2.5‑litre four‑cylinder it’s bolted to the engine block below the intake manifold. On the 3.5‑litre V6 there are two, mounted to the block in the valley beneath the intake. Access usually means removing the intake components, so plan on new gaskets.

Can you drive with a bad knock sensor?

Short trips are typically okay, as the ECU will pull timing to protect the engine, but performance and economy will drop. Prolonged driving isn’t recommended—get the wiring and sensor checked and repaired to avoid masking real knock and potential engine damage.
