Oil pressure light on and sensor not working

I suggest you find a new shop. They may have damaged the sensor, not plugged it in or damaged the plug. Here is a link to find a good shop near you and get a second opinion. https://repairpal.com/repair-shops Alex

If you are still comfortable with the shop that did the repairs, then you should take it back to them and let them make sure it isnt related to the repairs and fix it for free for you if it is related. As a professional facility, I would appreciate the opportunity to correct something like that directly after any repairs we make. If they give you any grief or concerns or if you just want another shop to look into it then we would be glad to help at Street Tech. If it turns out related then you have evidence from a credited shop. Hopefully they just take good care of you and you wont have to worry about anything like "evidence".
