Customer Question
2005 and i went...

2005 and i went thru not high water but just enough. 3 days later, my check engine light came on. we checked the codes and last one showing was P0455 also the the O2 sensor was changed and all gaskets. gas cap was changed. but still it went off for 1 week, and now it came back on yesterday. what else can we do.?????

Mechanic's Assistant: Does the light stay on, or does it blink?

It stays on

Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

My brother is a certified mechanic for and he has checked all the codes and went by that. it went off for 1 week and now back on

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

My vehicle is in good condition even that it is 2005 model i have had no major problem with it. thanks
