i just changed the oil and filter on my 2006 is 250 awd. When I got to highway speed the check vsp light appeared. The code it threw was p0021. Could I have improperly installed the oil filter to cause oil pressure problems. The spring and clip that holds the filter tight fell apart when I removed the filter. I thought I reinstalled it properly but now I'm wondering.

 

What else did you do other than oil change, have you ever touching any wiring

 

No, but I checked under the hood for any loose hoses anyway. I'm thinking that the screen that the filter goes over may have been thrown out with the filter . As I don't remember seeing it as I installed the new filter in the housing. I ordered a new housing off amazon as a precaution and will remove the old one when it comes on Wednesday. I think I'll park the car and drive my truck till then.

one cause is Low Oil Level........not good after you say you just done oil change! You could have lost a lot of oil due to mis fitted filter?

I removed the oil filter housing and housing he filter was shrunk in from not having the stainless screen inside of. When I removed the old filter I didn't realize the screen went with it. I ordered a new housing off amazon and replaced it and a new filter. I drove it today with no problems.
