Replace your failed engine computer with an OEM 2009 Nissan Altima 2.5L ECM (also called a PCM or ECU), programmed to your vehicle before it ships.

This module is a direct replacement for units carrying part number 23710-ZN65A and manufacturer note MEC120-180 B1. Every unit is refurbished, bench-tested against OEM specification, and flashed with the latest manufacturer software.

Compatible and interchangeable part numbers: 23710-ZN65B, 23710-ZN66A, 23710-ZN67A, 23710-ZN68A, MEC110-260 B1, MEC120-181 A1, MEC120-190 B1

Check your emissions type before ordering

These modules are not interchangeable between Federal and California emissions vehicles. Check the emissions sticker under your bonnet before ordering. If you are unsure, give us your VIN and we will confirm which unit your car needs.

Why Nissan modules must be programmed

These vehicles use the Nissan Anti-Theft System (NATS). The engine will not start unless the key, immobiliser and engine computer are all registered to each other. We programme the module to your VIN before it ships, so it arrives ready to install.
