Parts for your 2016 Mitsubishi Outlander-Knock sensor

2016 Mitsubishi Outlander knock sensor — what it does and how to look after it

Technical references confirm the 2016 Mitsubishi Outlander petrol engines are fitted with a knock sensor, while the diesel variant is not. The Mitsubishi Motors Outlander (GF/GG, 2013–2018) Service Manual, Group 13A – Engine Control, details knock-sensor monitoring and DTCs such as P0325/P0328 for the 2.0L/2.4L petrol MIVEC engines. The Mitsubishi ASA/CAPS parts catalogue lists a block-mounted knock sensor for these petrol engines. By contrast, the 2.2L DI-D (4N14) diesel engine workshop literature shows no conventional knock-sensor input, combustion control relies on rail pressure, injector strategy and other sensors, making a petrol-style knock sensor not relevant to the diesel model.

For owners of petrol 2016 Outlanders, the knock sensor is a quiet hero. Bolted to the engine block under the intake area, it “listens” for knock (pinging) and tells the ECU to tweak ignition timing on the fly. That keeps the engine smooth and protects it from damage when fuel quality varies or conditions get toasty under the bonnet. It’s not a wear-and-tear item like filters or plugs, but it plays a big role in performance, fuel economy and long-term engine health.

There’s no set replacement interval for the knock sensor on the petrol Outlander. It should be checked or replaced only if there’s a fault. Typical clues include a Check Engine light with codes like P0325/P0328, flat acceleration, rattly pinging under load, or unusual fuel use. A scan tool and a proper wiring inspection are the first steps, many “knock sensor” faults end up being a rubbed-through loom, a poor earth, or the sensor being incorrectly torqued after other work.

If replacement is needed, go for genuine or high-quality aftermarket and make sure it’s seated on a clean, dry block surface. Correct torque matters because the sensor reads vibration through its mounting—too loose or too tight can throw its ears out. While the manifold is off, it’s smart to check adjacent loom clips, intake gaskets and coolant hoses—save yourself a second tear-down.

A few everyday habits help the knock sensor do its job: use decent-quality petrol (91 RON is fine, 95/98 can help under heavy towing), fix misfires promptly, and avoid oil or coolant leaks that can soak connectors. With that, the sensor will quietly keep timing in the sweet spot for many kilometres.

• Common symptoms: CEL with P0325/P0328, pinging under load, sluggish performance.
• Service tip: verify wiring and ECU grounds before condemning the sensor.
• Fitment note: petrol models have a knock sensor, the 2.2 DI-D diesel does not use a conventional one.

FAQs

Where is the knock sensor on a 2016 Outlander?
On petrol models it’s threaded into the engine block, typically beneath the intake manifold near the centreline of the block. Access often means removing intake hardware. The 2.2 DI-D diesel doesn’t use a conventional knock sensor.

What are the signs a knock sensor is failing?
Expect a Check Engine light (often P0325/P0328), lacklustre acceleration, pinging under load, and sometimes poorer fuel economy. Always confirm with a scan and wiring checks—wiring faults are common culprits.

Should it be replaced as preventative maintenance?
No—on the petrol Outlander it’s replacement-on-condition. Test first, and if it’s faulty, fit a quality unit and torque it to the workshop spec. Consider fresh intake gaskets if the manifold comes off during the job.
