Nissan NP300 ECU Replacement Parts

Yes, every variant of the NP300 Navara has an ECU (engine control unit) — it manages fuelling, ignition timing and emissions across all engine options in the range. Whether you have the 2.3-litre twin-turbo diesel (YS23DDT) or any other engine fitted to the NP300, there will be an ECU on the vehicle. The key thing to know is that the ECU is matched to the engine code, so the engine code on your V5 or a VIN check is the most important detail to have ready when sourcing a used unit.

The engine code is the single most useful piece of information — for the NP300 Navara the most common engine is the 2.3-litre diesel, which carries the code YS23DDT (twin-turbo) or YS23DDTT (the higher-output version), though you should verify your exact code from your V5 or a VIN check rather than relying on the badge alone. Fuel type and gearbox type (manual or automatic) also affect which ECU is the correct match, so have those details ready too. Body style and trim level make no difference to ECU fitment.

The NP300 Navara was introduced in the UK around 2015 and received a notable update in 2019, so there is a production boundary worth flagging. Whether an ECU from a pre-2019 truck will directly interchange with a post-2019 vehicle is something you should confirm with the breaker against your exact registration and engine code, as ancillary and calibration changes can occur mid-production. If both vehicles share the same engine code, fuel type and gearbox type, fitment is more likely — but the breaker should verify part numbers before you commit.

Yes, gearbox type does matter for ECU compatibility on the NP300 Navara, because the ECU communicates with the transmission control system and calibration differs between manual and automatic versions. Always tell the breaker whether your vehicle is a manual or automatic, alongside the engine code, so they can match the correct unit. Fitting an ECU from the wrong gearbox variant is unlikely to work correctly.

Trim level does not affect ECU fitment on the NP300 Navara — the ECU follows the engine code, fuel type and gearbox type, not the trim name. Whether the donor vehicle was an Acenta, SE, Tekna or any other grade, it makes no difference to compatibility provided the mechanical specification matches yours. Do be aware that trim levels can come with different optional equipment, but none of that changes the ECU itself.

ECU pairing and immobiliser coding are areas where practice can vary and where you should confirm the specifics with the breaker and a qualified auto electrician rather than assume it will be plug-and-play. On many modern vehicles a replacement ECU requires coding to the chassis to work correctly with the immobiliser and other systems. Ask the breaker about this before purchase so you understand the full cost and process involved.
