I have two issues, maybe they arent related.

The first is that my check engine light is on due to P0442 code - EVAP emissions small leak. I think I know how to track this one down, but I would like to know if this could be related to my next issue...

My ABS and Parking Brake lights come on and "dings" after I drive the truck for about 5 minutes (maybe less, but it certainly isnt right away)

I have heard to check the sensor on the rear diff, but mine is plugged in. Not sure what else to check.

Thinking about unplugging the sensor and heading down the road to see if anything different happens....

any help for a newb to this forum would be greatly appreciated!!!

Welcome to the forum! Small evap leaks can sometimes be a pain, you may need to hook up a smoke machine to find the leak. If the abs lights comes on, it probably stored a code. Were there any abs codes?

I had an issue with the brake and abs light popping back this spring. It was from low brake fluid in the reservoir. One on my brake hoses had a slight split in it that allowed for a slow leak.
