Question

I got the engine code P0442 on my 2001 Ford Ranger V6, what could cause P0442?

Answer 1

Hi there,

There are several things that can bring this code up. The code is for a small leak in the evap system. One common cause is the gas cap. If it's loose or the seal isn't a good seal on the fill tube then it can leak. If the gas cap is fine, then a smoke test is the best method for finding the leak.
