2015 Pajero Sport Intermittanty Limop Mode and power loss
Posted: Wed Jul 22, 2026 12:23 pm
Hi All
I am reaching out here as I just want to get some feedback to see if anyone else have has the same issue.
My 2015 Pajero Sport 2.5 - Goes Into Limp mode every now and them - Usually happens on an uphill.
The vehicle has a new turbo fitted about 1000km ago. It pops up the following error codes when this happens -
U1120 - This code refers to comms between the ECU and the Gearbox unit ( according to the scan tool )
P1298 - IDM Failure ( according to the scan tool )
So herewith my question - Its an intermittent fault. Happens one in a while.
I have tried to find the Gear Box Control unit - All I could find was the control unit situated on the left hand side of the passenger footwell - HAs two plugs with millions of wires at the bottom.
I just want to check the plugs where it goes in and out of the gearbox control unit to the ECU - to ensure the plugs connect well and perhaps clean the contact - as a quick resort.
ANyone else had this issue and manage to resolve it ? Or is there another point inbetween I am missing ?
Any advice would be helpful Thnx
