Can anyone help with what I can check when I get the engine symbol on my dash?
Book says it is "Malfunction indicator" and it indicates "a problem somewhere in the electrical system, electronic engine control system".
The warning came up driving and everything seems ok other than engine lacks power climbing hills, which have never caused any problem. I am still able to travel comfortably along flat road without trouble.

Probably went into limp mode due to hot transmission fluid.

Buy a Scangauge and set it to show TFT and see if that confirms it.

I'm glad I ain't too scared to be lazy

If it's the toyota in the profile photo, it won't be an auto
But get some one with a scan guage to check the code/ clear it.

Please don't clear DTC's, it makes it very hard for someone like me to fix the problem and if under warranty Toyota will not accept a claim without seeing the DTC's themselves.

Not all DTC's pinpoint the exact fault.

Thanks Pete,
I was going to take to the local dealer but work commitments make it hard. Just thought if it could be something simple like when they tell you to take it to the dealer for blocked fuel filter which is a different symbol I could have checked any suggested sensors

Absolutely nothing, the warning light and limp mode can come on for a number of reasons, when the engine light does come on it will leave a fault code that can be accessed by a scan tool.

Limp mode is designed to save something from being damaged like overboost, temp, excessive load or a number of other things BUT it can also be caused by a non critical fault that has happened a set number of times over a given time span.... or voltage, earth or communications problems.

If you want to try and pinpoint it without a scan tool I would suggest starting at the bolts that hold the number plate on the rear on and work forward........

Why not start at the front numberplate, it is likely to be closer to the problem!

Great Idea Thanks.... I'll go with front plate back. I plan on checking everyhing that is jammed under and around the intercooler is connected and secure.
Thanks for the advice

Log on to the Lcool website - it doesn't cost anything and it covers most if not all LandCruiser models.

Ross I was in a workshop when a Toyota came in with the engine light on and it had gone into limp home mode. After we checked with the carman we found it had a brake code come up, after checking the brake system and couldn't find anything wrong, then we checked the brake lights and guess what a globe was out.

After a new globe and clearing the code all was good, so this time the problem wascloser to the rear number plate.

Thanks Phil,
After posting the problem it has been great to have so much help.
The first sign of a problem was coming over the mountains from Inverell to Narrabri. Usually select 5th gear (manual transmission) and just sit back. Lacked power on hills needed to change gear.
I understand what everyone has been saying about limp mode, this was different. Plenty of speed along the flats.
During the week warning symbol came up.
Okay things I did in order of priority.
1. Put post on forum.
2. Checked fuel filter as Toyaota donot scheduled time to change.
3. Changed fuel filter.
4. Checked forum and read all suggestions.
5. Cleanned battery terminals. That would have reset fault symbol.
6. Took for drive and I had almost forgot how much low down torque and power these motors have.
7. Thanked all again... Oh What a Feeling Toyota!

The fuel filter maintenance light will come on way before the filter is blocked enough to cause a noticeable loss of power, and it will not bring on the engine check light.

Take it to Toyota and for $75 get them to read the fault codes..... or find someone with a REAL scan tool and get them to do it, don't get them to reset/clear the code.

Thanks,
I'LL take your advice but Im sure if there is a problem the engine warning will come back on, as the fuel filter light does when you try and "trick" it when your miles from nowhere without a spare and it comes on.
The filter I replaced is the only thing I have done and the power is back as new.
I will still take it to Toyota, just now I should be able to do that when I can instead of thinking why the warning is on
