   Hi all i have a 01 vts and today i connected the ecu to my PC by lexia. I have a few question that i need answers from you guys.
   
   1. My inlet temp sensor is showing 70°C. That not good and can somebody explain me why is that i was checking when the engine was cold just started.
   
   2. My coolant temp sensor is showing 77°C.
   
   3. I have a decat how to disable the elm when its showing the the downstream sensor fault.
   
   So what i have to check or do something to fix this. Maybe its something with the ground or something because i had issues before with the ecu. By the way the car runs fine and has no troubles.

   1.2. get a new temperature sensor
   
   3. plug the bottom lambda sensor back in. You should not disable the eml, purely because next time you have a problem you won't see it. Do what's necessary and the eml will turn itself off, or unplug the battery for a few minutes.

   I doubt that, the car will overfuel should the lambda sensor being faulty or unplugged. It is a false economy in the long run purely because it costs you more petrol.
