Hello, we have a code on our 2001 Chevrolet Suburban. The code is P0442. Went to Firestone and the tec can't fix or reset the code. We were told it may be the gas cap.

Hi there,

Your code is

P0442 Evaporative Emission Control System Leak Detected (small leak)

This could be a number of items so get your mechanic to do a few tests on the system.
