Question

My 1999 Cherokee has this code (PO455) where can I find a diagram of this system? tnx.

Answer 1

HI there

This code is for a large leak in the evap system. This could be as simple as the gas cap being loose or something more complicated like an actual leak. If replacing the gas cap doesn't help, then a smoke test should be performed to locate the actual leak in the system.
