1998 Volvo VNL64T610 keeps shutting off

I got a 1998 Volvo VNL64T610 with the Volvo VED12 that I’m having an issue with. Sometimes the oil pressure gauge will go to zero and STOP will flash on the dash then truck shuts off. Says check diagnostics on dash. If I let it sit for a minute it starts back up and runs fine but starts acting up again pretty quickly.Started as an intermittent problem but now it’s pretty bad. I’m wanting to change the oil pressure sensor to see if it solves the problem but I can’t seem to find it. I know it’s on the drivers side, looks like it might be down by the starter but im not sure if that is it or not, if that is it it looks pretty difficult to get out. Anyone know?

 

That’s kinda what I was thinking. After looking at it for a while, looks to be where it’s at, gonna be a pain to replace the way it looks. Thanks!
