Replace the engine computer when you face recurring engine-management faults or a permanently lit check-engine light that cannot be reprogrammed, since a failed unit hurts performance and fuel economy.

• Replacement sign: Permanent check-engine light, rough engine running, or failure to communicate with the diagnostic scanner.
• Approximate lifespan: Typically lasts the life of the vehicle, beyond 200000 km, unless damaged by electrical faults or moisture.
• Install requirement: Requires programming and coding with a specialized tool to match the vehicle, and is best fitted by a qualified technician.
