Turbo warning light ?

[Richard Creighton]

What causes the turbo warning light to come on, ie what is it warning you of ? i have a 1996 4 runner 3.0L TD driving back to france from the uk last night at a steady 130kilometers per hour just over 3000 revs, and the orange turbo light would come on for about 5 mins then go off again, then half an hour later the same thing ? over the course of my ten hour journey the light came on about a dozen times, why might this be ? a reply in lay mans terms would be apreciated,

Thanks
Richard.

Hi there!
If you drove 10 hours about 130km/h, what do you think?
Diesel engines heats very fast and need to stop from times to times to cold.

At that constant speed, the turbo overheat and may cause a faillure.
Take care....

A diesel engine will run 24/7 at that speed with no problems.

A diesel engine will run 24/7 at that speed with no problems.

Well, try to run 10hours in a 40ºC day and see what happens.
(Here in the south of Portugal and Spain.)
If the engine runs without probs at that speed, then the turbo, in this case, have probs?

I'm curious about this peculiar subject.

its more of a engine fault light than turbo light on 4Runners, you need to pull the fault codes and see whats amiss.

Theres plenty of info here on checking fault codes.

I've done close to that here in Australia when over 40 deg C and don't have a problem.Ambient temperature has little to do with engine operating temperature.If the cooling system is working efficiently then there won't be a problem.

Thanks for the responses, where do i get the fault code from ? do i have to plug some sort of gadget into the car ? the car has had this problem since i bought it, i dont think its heat, i was travelling through the night and sunday night was clear and very cold, i had a problem with the engine which turned out to be a cracked cylinder head, (unusual i am told in the 3.0L) but that was replaced with a brand new head only 6 weeks ago. but the turbo light came on intermitantly before the head went, i am hoping the 2 problems are not connected, again any advice is welcomed.

From my understanding of the 3.0TD turbo light, it only comes on when the turbo is overheting.
Check your oil level and grade....make sure you are getting pressure.

I may be wrong but seem to remember reading that the warning light indicates turbo pressure running either too high or too low. According to the Toyota 1kz-t workshop manual if the pressure should become too high than a waste gate valve would release excess pressure to return to normal operating limits.

Warning Light

If the 4-Runner is the same system as the Surf 3.0 TD,the orange light in the tacho warns of a problem with the engine,and not just the turbo.As has been mentioned,you need to access the fault codes to determine the problem.For the Surf 3.0 have a look at: [url]www.showmesome.info/hilux/info/manuals/1KZ-TE.Hope that helps.

I have had this a number of times with my 4.2 Landcruiser VX and although I change the oil filter and oil at 4500 mile intervals an oil change seems to fix it. On one occasion the cause was the flexi in the exhaust system blowing.
