i have a 2014 focus 1.0 ecoboost took the car into the ford dealer for them to find out why the egine was misfiring after being told by 2 other garages that it was the high pressure fuel pump and the pump in the tank replaced both of them and still had issues they replaced the fuel injector on cylinder 3 that fixed the misfire but its still got a check engine lights on had a garage scan the car and these are the codes its come back with just wondering if there is anything i have missed as to why its still having issues

 

p008a  fuel low-pressure circuit / pressure to low

p2636 - fuel pump b control circuit / low flow rate

p0137 - 02 sensor (bank 1 sensor 2)   low voltage     

 

think the p0137 02 sensor is due to the exhaust flex having a hole in it waiting on the repair part to be delivered for that 

 

but no idea what to do or look at with the fuel pressure issues the car runs fine 

 

thanks 

 

 

Have the codes been cleared to see if they come back? They could be old ones that have been there since the fuelling problem.

hi yer cleared them and they have come back on 

I would get the hole fixed first then clear codes and see what happens as the leak may be causing issues.
