Greetings and welcome to Just Answer. My name is Mark.

Okay, if your engine isn't experiencing any engine mechanical issues, most likely the engine oil pressure switch has failed. I can give you instructions on repair and replacement, however, you are mentioning you have a V-6 in this vehicle. I see the choice are a straight in-line 6 cylinder or a V-8. The repair procedure and switch location is different. Do you know what engine for sure you have in your vehicle ?
