Engine fault light

[seivad]

A friend has been having problems with a fault code that their mechanic tells them indicates a problem with the EFI or pollution management system. The vehicle is a 2003 Triton Ute, petrol engine, not 4WD. The vehicle seems to run OK. The fault light does not go out when the battery is disconnected and reconnected. They are considering "painting out" the engine fault light to avoid the irritation - a choice I have tried to oppose. Suggestions have included checking the sensor that send the signal, and its associated wiring. Has anyone a link to a wiring diagram that might assist in sorting out this problem?

You need to read the fault code in the ECU and post it here. This will give you and us a big clue as to why the light is coming on
