Recent History: The engine and gearbox have recently been reconditioned / rebuilt. Engine easy starting all the time. Its Winter at this time.

Engine check light comes on after approx. 30 to 45 mins highway driving. Sitting on 90 kms to 95 kms / hr.

Startup in morning the check light stays on for a few seconds and then goes off until highway driving of approx. 45 mins it comes on. Engine performance doesn't seem to diminish and is not in 'limp mode' if the vehicle has that? I don't know. Still can drive at 90kms per / hr.

In 4WD low range I recently drove the vehicle in some rough country for over a hour and the check engine light stayed off. Engine oil is new, and there is no coolant loss. Engine dosen't overheat according to the temp gauge. Stays constant on halfway of the temp gauge, give or take 0.5mm.

It seems the check engine light will only come on when engine is at operating temp, driving highway speeds, (90 to 95kms per /hr), and will stay on until engine turned off and engine has cooled down. I have disconnected the battery and the code clears but returns as i drive down the highway within minutes. Driving to and from work and around town the engine light stays off (Approx 20 to 30mins max running time).

Any ideas what to do, what to check? Do i need to visit a dealer for dealer level scan? Look forward to your advice Owl.

It sounds like a sensor is deteriorating and only fails with sufficient heat soaking from significant use. You say you have cleared the codes, did you record what they were as it would narrow down the list of sensors?

Gday Dreadnaught, thanks for input, For clearing the check engine light I just removed the neg lead from battery for a few mins and replaced it while I was driving on the highway. Check engine goes off. Dont know how to read the codes my scan tool is locked out. (OBD1). Ive got the Vident scan tool, supposed to do jimnys but not mine, has an error code 1902 locked . Contacted the company over 3 months ago they said they were going to give me a fix, its not coming as yet.

that said, something else appeared today , a big squeal from the alternator i'd say, its a loud high pitched squeal which appeared. Under more load by putting lights on the squeal gets louder. Belts are as new on this one, have done around 500kms on the engine. IIts efinately coming from the alternator side.
