Urgent help with 07 fiesta

[rocketilitietron]

Hello people

Newbie here,

Just wanted to ask a quick question

I have a 07 reg fiesta 1.2 style and i just wanted to ask,

How long does the ecu store the codes for?

I mean if it stores a code how long with the ecu reader be able to look back?

Please help, Look forward to your reply.

It will store the codes until they are cleared with a reader, although on some ecu's they will store the last cleared code.
