Hi All,
A Happy New Year to All.
I have a 1998 3.5 Petrol Jackaroo, and is the past 12 months the engine
check light has been coming on.
I have worked out a patter, and this may sound silly but it comes on only when the air is not 100%, for example when following a smoky vehicle, or if the air is not clean, for example it came on when the bush fires here in Vic had the air very dirty.
The light goes off once the air is ok and clean again.
Does any one know what engine sensor would be causing this?
Hoping someone can help.
Craig.

My first guess would be the O2 sensor.
They monitor the gases and adjust the engine accordingly. They are very sensitive but don't always need replacing when the light comes on.
I would get it checked out to be sure but to me it doesn't sound serious.
We have gas on our Frontera (3.2 version of same engine. Thought it was only later Jacks that had the 3.5 though). Our engine light remains on due to the LPG and goes off evenutally when running on Petrol. The longer on gas the longer it takes to go off. It can take more than 1000k's. Advice given to us to FIX the problem was to disconnect the light, DUH. (by the gas boofs not by Holden though)
We clean the sensors ultrasonically and thet are then just fine.
We have 2 sensors on ours and they are around $200 ea and not compatible with anything else it would seem. That's $400 to get the light go out for a while.
Hope that's all it is for you.
Cheers
