Hi,

 

It depends on which engine:

 

  • 2.2L engine the ECM is located on the intake manifold, under outlet resonator/duct assembly
  • 3.0L engine the ECM is located below the battery cooling box

2.2L:

If I do decide to pull the fuses that cause the check engine soon light to go off, will I miss up all of the electronics on my Saturn Vue?

I have no idea what size engine I have. I was always told it was a 4 cylinder.
Expert:  Eric replied 7 years ago.

Hi,

 

4cyl is 2.2L

 

If you are pulling the fuses to make the check engine light to go off, it wont work. Pulling any of the fuses that control the ECM will prevent the vehicle from starting or running. There isnt a fuse for just the check engine light bulb itself.

 

The ONLY way the check engine will go out and stay out is if it is first diagnosed and then properly repaired.

 

I realize this probably isnt what you want to hear, but if you have been told anything else you have been misled.
