Turbo Light

[Phil her up]

At 18000 RPM your engine would fly apart. 1800 would be more likely!!

Ref the original question, the turbo light only works as such on the 2.4L. The 3.0L doesn't have one, only the engine check light.

What is the purpose of the engine check light on the 3.0L?

[BUSHWHACKER]

It's for fault finding purposes.

if it comes on... check the engine... in fault mode it will flash, count the flashes to find the fault!

look in general servicing for fault codes

Thanks Guys
Now I have the understanding how do I make the fix??

is the turbo working?

Mine goes out when engine started, I presume this is ok then?
Does it come on or flash if there is a ecu problem or something like that then?

[BUSHWHACKER]

It goes out after the engine has started.
If it comes on when you are driving, it means there is a problem that one of the engine sensors has picked up and the code will be stored in the ECU for recovery.

Don't know

is the turbo working?

I do not know much about how they work. Am I supposed to feel a surge or see the counter jump once past a certain RPM? If it runs off of the outlet manifold how can it not work? The blades turn freely.

The light should come on at around 1800 rpm, and you should be able to hear the turbo whistle.

you will be able to tell if it's not working, verrrrrrrrrrrrrrrrrrrrry sloooooooooooooooooooow truck!

That the same as being sluggish?( I was of the opinion that the truck was lazy)

Where does the signal for the light come from?

[BUSHWHACKER]

Yes it will be very slugish!


This is the air temp. sensor.

I find the light very annoying, as it is basically always on during normal driving.
You will not feel a "kick" as in a turbo powered petrol engined car, as he turbo it an LPT, low pressure turbo. Its just to help rather than make massive performance gains.

I would imagine that the light is just a very primative boost gauge, than senses when the turbo boost reaches a certain level and just comes on, to let you know its working.

though as has been stted here, if it wasnt working, you'd know about it anyway as you'd not hear the whistle, and surf you'd be even slower!!

Turbo Sorted

Thanks a MIL Bushwhacker and all who gave info.

The Diagnosis was that my vacuum line to turbo sensor got knocked of while I was tinkering and Temp sensor was not plugged back in
