Po 155 code - 2002 Dodge Intrepid

If these codes only show after rain then the moisture is affecting the connections in the wires. Pull each connector apart and clean out with wd-40 or other water dispersant and ensure that the connections are water tight. Any dirt ,oil ,grease green gunk on the pins will cause a problem
