2017 Mitsubishi Eclipse Cross EGR Valve

Based on technical references, this model does use an EGR valve. The Mitsubishi Motors Eclipse Cross (GK) Workshop Manual (2017MY) – Engine Control section documents an electronically controlled, cooled EGR system on the 1.5‑litre 4B40 turbo‑petrol, and an EGR valve with cooler on the 2.2‑litre 4N14 turbo‑diesel. The Mitsubishi ASA global electronic parts catalogue for GK series likewise lists an EGR valve assembly for both engines, and independent data services (e.g. Autodata/Autoinfo emissions diagrams) also show an EGR valve on the 2017 Eclipse Cross. So yes, an EGR valve is relevant and fitted on this vehicle.

The EGR (exhaust gas recirculation) valve on a 2017 Mitsubishi Eclipse Cross recirculates a measured amount of exhaust back into the intake to bring combustion temperatures down. That helps cut NOx emissions and, on the 1.5‑litre turbo‑petrol, also helps part‑load efficiency and knock control. On the diesel, EGR is a big player in emissions, working alongside the DPF and turbo to balance NOx and soot. It’s all computer‑controlled and, on these engines, usually paired with an EGR cooler.

It isn’t a scheduled “replace at X km” item, but it does benefit from periodic attention. Petrol versions tend to run cleaner, though direct injection and short‑trip city driving can still leave carbon on the valve and in the intake. Diesels see more soot by nature, so the valve and cooler can coke up faster, especially with lots of low‑speed use.

Typical symptoms of an EGR issue include a check‑engine light, rough idle, hesitation off the line, poor fuel economy, pinging on the petrol, or excess smoke on the diesel. Common codes a tech might see are P0401 (insufficient flow), P0402 (excessive flow), P0403 (circuit) or P0405/P0406 (position sensor).

As part of servicing, a workshop will often:

• Scan for EGR‑related DTCs and check live data for commanded vs actual EGR position.
• Visually inspect the valve, cooler and plumbing for leaks, carbon build‑up and sticking.
• Clean the valve and intake where appropriate (diesel especially), and update ECU software if applicable.

Replacement is on the cards when the actuator or position sensor fails, the valve’s shaft is worn, the cooler is internally blocked, or cleaning won’t restore proper flow. It’s smart to fit new gaskets, torque fasteners to spec, and bleed/verify coolant if the system uses a cooler. Expect around 1–2 hours labour on the 1.5T petrol and a bit more on the diesel depending on access. Keeping to quality fuels, regular oil changes, decent motorway runs, and making sure the PCV and intake are clean will help the EGR live a longer, happier life.

Popular questions about 2017 Mitsubishi Eclipse Cross EGR valves

Does the 2017 Mitsubishi Eclipse Cross have an EGR valve?
Yes. Both engines offered for this model year—the 1.5‑litre turbo‑petrol (4B40) and the 2.2‑litre turbo‑diesel (4N14)—use an electronically controlled EGR valve, with a cooler in most configurations. It’s part of the emissions and efficiency strategy.

How often should the EGR be cleaned or replaced?
There’s no fixed interval in the service schedule. Many workshops inspect around 60,000–100,000 km, cleaning as needed—more often on diesels that do short trips. Replacement is only necessary if the valve or position sensor fails, the actuator sticks, or the cooler is badly blocked.

What fault codes point to an EGR problem on this model?
Common EGR‑related DTCs include P0401 (insufficient EGR flow), P0402 (excessive flow), P0403 (circuit fault), and P0405/P0406 (position sensor range). A scan tool and an EGR functional test are used to confirm the fault before cleaning or replacing parts.
