Yesterday I replaced a faulty crank sensor before heading on a two week trip. 20 minutes into the trip I get the check engine light come on.

I have returned home and ran the codes using the key dance.

I get 12, 51 and 53

12 - The battery has been disconnected and the computer (ECU) has been reset.

51 - engine running too rich or lean

53 - Logic module fault

Do I take these seriously? I'm meant to be away for two weeks. Should I wait to see my mechanic on Monday and leave then?

 

Code 12 is not to much to worry about most of the time.... But the other 2 are going to take a scan tool to figure out...

 

Thanks for your reply. I'll sit tight and get some pro help on Monday. Thanks!

 

Keep ua posted...
