2002 TB Low Oil PSI at Idle

[garednck]

I have a 2002 TB and today while towing a trailer I noticed the oil psi dropped to zero when I came to a stop light. I pulled out and checked the oil and the level was full but a little dirty looking. I restated the engine and didn't notice any ticking nosie from lack of oil. I went ahead and drove it back home and every time I stopped the oil psi would drop to Zero. I went ahead and changed the oil and filter and re started the vehicle. The oil psi was about 40 psi. I went for a drive and didn't have any issues until after I had driven about 12 miles and it started doing it again when I came to a stop. Could this be an oil sensor issue?

Could be, get an seperate oil gage on it see what the press. is.

That's a funny problem. My old Astro van, '88, is pulling the same stunt. Did you find anything out?
