Had the P0441 and P1421 code. The Evap #1 hose was hard/stiff and no longer held a tight seal. Replaced with a new hose that was soft. It sealed much better and code was cleared. Will replace #2 and #3 hose if the codes return. So far good to go!

What are other possible reasons to throw EVAP codes if it’s not hoses #1, #2 , or #3. Any one have experience, technical knowledge they would share or pass on. Both my wife and grown daughter, my princess, have older Rx’s and trying to do my best to keep them humming along well past 200k. My appreciation in advance.
