Parts for your 2013 Mitsubishi Outlander-Knock sensor

2013 Mitsubishi Outlander knock sensor: fitted on petrol models, different strategy on diesel

Based on technical sources, a knock sensor is used on 2013 Mitsubishi Outlander petrol engines, and it’s relevant to routine diagnostics and repair on those models. Mitsubishi Motors’ 2013 Outlander (GF-series) Service Manual describes a block-mounted, piezoelectric knock sensor feeding the engine-ECU for ignition control and lists related DTCs (P0325–P0334). The Mitsubishi Electronic Parts Catalogue (ASA/EPC) also lists a “sensor, knock” for the 2.0L and 2.4L petrol variants used in this model year. Independent workshop databases (e.g., ALLDATA/Autodata/HaynesPro) show the sensor and its two-wire circuit in the engine management schematics for the 2013 petrol Outlander. For the 2.2 Di‑D diesel, those sources indicate no conventional knock sensor, combustion is managed via rail pressure, injector control, and crank/cam feedback rather than spark timing.

On the petrol 2013 Outlander, the knock sensor is a quiet achiever. Bolted to the engine block, it listens for the high-frequency “ping” of detonation and tells the ECU to tweak ignition timing so the engine stays happy. That means better longevity, smoother running, and solid fuel economy on everyday 91–95 RON, while still protecting the engine if the fuel isn’t flash or the day’s a scorcher.

It’s not a scheduled replacement item, but it deserves attention during servicing. A tech will usually:

• Visually check the sensor body and plug for oil, coolant, or corrosion.
• Inspect the loom where it runs under the intake for rubbing or hardening.
• Scan for DTCs like P0325 and look at live knock correction data on a road test.

If the light’s on or the Outlander feels flat, rattly on load, or uses more fuel than usual, a lazy or disconnected knock sensor could be the culprit. Before throwing parts at it, it’s smart to rule out basics that trigger knock detection: overdue spark plugs, low-octane or stale fuel, intake leaks, or heavy carbon buildup. If the sensor itself has failed, replacement is straightforward with the right access: battery negative off, connector unclipped, sensor swapped, and tightened to the workshop manual’s torque so it can “hear” properly. Over- or under-torquing can dull its ears.

Quality matters here. An OEM or reputable brand sensor, fitted with a clean mating surface and correct torque, will keep the ECU’s timing strategy sharp. After replacement, the technician will clear codes and take it for a decent drive so the ECU relearns. If it’s a diesel Outlander, there’s no traditional knock sensor to replace, any rattle or performance issue is chased through the diesel systems instead.

Popular questions about 2013 Mitsubishi Outlander knock sensors

Where is the knock sensor on a 2013 Outlander?
On the petrol four-cylinder, it’s mounted to the engine block under the intake side, roughly mid-block so it can “listen” evenly. Access varies with tools and intake plumbing, so some models are quicker to reach from above, others from below with shields off.

What are the symptoms of a bad knock sensor, and is it okay to keep driving?
Common signs are a check engine light, sluggish acceleration, higher fuel use, and sometimes audible pinging under load. The ECU will usually pull timing to protect the engine, so it’ll feel down on power. It may limp along, but it’s not ideal—get it scanned and sorted to avoid long-term wear.

Does the 2.2 Di‑D diesel have a knock sensor?
Not in the same sense as the petrol. The diesel’s combustion is controlled by injection timing, rail pressure, and feedback from crank/cam sensors. So if a diesel sounds knocky, the workshop will look at injectors, fuel quality, EGR, boost and air leaks rather than a dedicated knock sensor.
