Parts for your 2007 Mitsubishi Lancer-Egr valve

2007 Mitsubishi Lancer EGR valve — fitted or not?

For Australian and New Zealand–spec 2007 Mitsubishi Lancer petrol models, an external EGR (exhaust gas recirculation) valve is not fitted. This is backed by technical references including Mitsubishi’s CH (2003–2007) and early CJ (MY2008 launch) service manuals for local petrol engines, the Mitsubishi ASA/Oceania parts catalogue, and Autodata component diagrams, all of which omit any EGR valve, pipes or control circuits on the 4G94 2.0L, 4G69 2.4L and 4B11 2.0L petrol engines sold here.

Why is there no EGR valve on these Lancers? Mitsubishi met the era’s emissions targets using engine management and aftertreatment without needing a separate EGR assembly. The petrol engines rely on precise fuel/ignition control, three‑way catalytic converters and, on 4B11, MIVEC variable valve timing to achieve a mild “internal EGR” effect via valve overlap. That approach reduces NOx and improves drivability without the added complexity of an external EGR circuit.

• Engine management: Stoichiometric AFR with closed‑loop O2 feedback and effective cats remove NOx, HC and CO.
• Valve timing: MIVEC (4B11) manipulates cam timing to dilute the intake charge internally, similar to EGR.
• Market tune: AU/NZ petrol calibrations and hardware lists show no EGR parts or EGR DTC strategy.

Common workshop cues line up with this: there’s no metal EGR transfer pipe from exhaust manifold to intake, no EGR cooler, and no EGR electrical connector on these local petrol cars. If an engine light appears for airflow or mixture issues, it will not be for EGR flow faults (such as P0401/P0402) on an AU/NZ petrol 2007 Lancer, so diagnosis should focus on intake leaks, MAF/MAP signals, O2 sensors, PCV system, or ignition.

There is one important exception. Certain overseas Lancer variants around this period used an EGR valve, most notably the European‑market 2.0 DI‑D diesel. If a vehicle is a grey import diesel, expect an EGR valve and cooler, and plan periodic soot clean‑outs and checks for sticking valves. For standard AU/NZ petrol cars, however, EGR servicing isn’t on the menu simply because the part isn’t there.

Technical sources referenced: Mitsubishi Lancer CH (2003–2007) Service Manual – Engine/Emission Control (AU/NZ petrol: no EGR system shown), Mitsubishi Lancer CJ (MY2008) 4B11 Service Manual – Emission Control (notes external EGR not used on 4B11 petrol), Mitsubishi ASA (Oceania) electronic parts catalogue (no EGR valve listed for AU/NZ petrol CH/CJ, EGR listed for EU diesel), Autodata AU/NZ component locations and wiring (no EGR on 2007 Lancer petrol).

• If an EGR valve is specifically required, the vehicle is likely a diesel import or non‑AU/NZ market spec.

FAQs

Does a 2007 Lancer in Australia or New Zealand have an EGR valve?
Local petrol models do not have an external EGR valve. Factory manuals and the OEM parts catalogue for AU/NZ petrol engines list no EGR components. Diesel imports from Europe are the main exception.

How does the 2007 petrol Lancer control NOx without an EGR valve?
Through precise fuel and ignition control, a three‑way catalytic converter, and variable valve timing (on 4B11) to create internal EGR via valve overlap. That strategy meets emissions targets without extra EGR hardware.

Which 2007 Lancers do use an EGR valve?
European‑market 2.0 DI‑D diesel variants use an EGR valve and cooler. Those vehicles benefit from periodic EGR cleaning to prevent soot‑related sticking and flow faults.
