Parts for your 2013 Nissan Pulsar-Egr valve

2013 Nissan Pulsar EGR valve — is it fitted?

For Australian and New Zealand–spec 2013 Nissan Pulsar models, an external EGR (exhaust gas recirculation) valve is not fitted or required. The 2013 Pulsar arrived locally as the B17 sedan and C12 hatch with petrol engines only: the MR18DE 1.8-litre port-injected four, and the MR16DDT 1.6-litre direct-injected turbo in the SSS. Technical information for these engines shows they rely on a three-way catalytic converter and variable valve timing (CVTC) to manage emissions, not a standalone EGR valve.

Referencing technical sources:

• Nissan factory service information for MR-series engines (MR18DE, MR16DDT) lists the EGR system as “not applied” for these petrol variants, with NOx control handled by stoichiometric operation and a three-way catalyst.
• Nissan MR engine technical overviews describe the use of CVTC (intake on MR18DE, dual on MR16DDT) to create internal EGR effects, reducing pumping losses and emissions without a separate EGR valve.
• Local 2013 Pulsar sales material in AU/NZ shows only petrol engines offered, no diesel variant was sold here at the time, and EGR valves are primarily used on diesels.

Why the EGR valve isn’t used on this Pulsar: on these petrol engines, the combustion runs at a stoichiometric air–fuel ratio so the three-way cat can efficiently clean up NOx. The cam phasing system bleeds a controlled amount of exhaust back into the cylinder (internal EGR) to cut NOx and improve efficiency, without the complexity and soot management that a cooled, external EGR valve would introduce. Nissan’s calibration and hardware on MR engines achieve the emissions targets without needing an external EGR assembly.

What owners should service instead: while there’s no EGR valve to worry about, keeping the emissions system healthy still matters. Good items to check under the bonnet include:

• MAF sensor and throttle body cleanliness (every 20–40,000 km, or if idle is rough).
• PCV valve operation and crankcase hoses for sludge or splits.
• EVAP purge valve/hoses and fuel cap seal if there’s a fuel vapour or EVAP code.
• Oxygen sensors and catalytic converter efficiency when chasing poor economy or a MIL.
• Ignition coils and plugs (iridium plugs typically at ~100,000 km, earlier if misfiring).
• For MR16DDT (turbo DI), use quality fuel and consider intake valve deposit checks over time.

If an online parts listing shows an EGR valve for a 2013 Pulsar, it’s usually a generic catalogue entry or refers to overseas models (including diesels not sold in AU/NZ). Always confirm by VIN and engine code before ordering.

Does the 2013 Nissan Pulsar have an EGR valve?

No. On AU/NZ petrol models (MR18DE and MR16DDT), Nissan does not use a separate EGR valve. Emissions control is handled by the three-way catalytic converter and variable valve timing strategies that provide internal EGR effects.

Why do some websites list an EGR valve for my Pulsar?

Many catalogues are global and bundle parts for overseas Pulsar/Sylphy/Tiida variants, including diesels or different petrol engines that can use EGR. The AU/NZ 2013 petrol Pulsar doesn’t have one, so check parts against your VIN and engine code to avoid a dud order.

What faults can feel like a “bad EGR” on a Pulsar?

Rough idle, hesitation or a check engine light on these cars is more often a dirty MAF or throttle body, a tired ignition coil, vacuum/PCV leaks, or an EVAP purge issue. Scan for codes (e.g., P0101, P0300 series) and inspect those systems first.
