Check engine light - P0442

Hey all, check engine light came on today and pulled code P0442 (98 zj 4.0). Should I just go ahead and replace the EVAP canister purge valve? Any recommendations?

Nope, that code is not for the purge valve. That code means you have a small leak somewhere in the system. Look for cracked rubber, bad gas cap, cracked hard line, etc.

Appreciate that thank you. I don't see any issues with the gas cap but I'll check out the others.
