98 Ford Ranger
Code # P1409 came up when we check on my 98 Ranger. I replaced the DPFE sensor (F77Z-9J460-AB) & control valve (F63Z-9J459-AA). The check engine light continues to come on after we erased it. Do you think it could possibly be the EGR valve?
I also have a problem with the interior light staying on all the time and the key chime (ding, ding, ding, etc.) sounding long after I have shut the door. Any ideas?
