Incorrect o2 sensor fault

[emma010208]

Hi looking for advice 

my car went into garage in march with engine light fault, diagnostic text showed o2 sensor issue this was changed twice and fault still remained, after further tests they changed the cpu. This seemed to fix the issue.

about a month ago the car lost power on a journey and engine light again came on. On diagnostic test the same fault with sensor showed again, after changing this twice the fault still remained …the garage now does not know the issue and not know what to do next….

anyone came across this issue?

Is this is for a Ford Escort? as you've posted in the Escort forum.

Profile says Ecosport...all the letters are there, just not necessarily in the right order!  

 

Best advice is to take it to another garage tbh.  Ideally one with Ford specific diagnostics.  This one is clearly throwing parts at it instead of making a proper diagnosis.  Do you know the exact code that is being triggered?  There are many for the O2 sensors.
