Oil pressure sending Unit

[Cedarhouse]

What is the correct OEM part number for a 1998 Jeep Cherokee 4.0 Oil Sending Unit?
Oil pressure almost drops to zero when stopping and back up to normal on higher speeds. (Just started)

Yep, I found 56031005AB. They are pretty failure-prone, even if you buy the Genuine Mopar. I went through 2 bad Mopar switches from the dealer before I got one that worked consistently, and I tested my oil pressure with a mechanical gauge at the port to verify.
