Ford Focus 1.6 - Engine Management

Recommended Posts

New poster, hoping someone can help a very distressed ford owner!!

The EM light has come on and I have a reader which gives me a couple of codes. One was the coil pack which has since been replaced and has prevented an issue I saw before where the car would Rev by itself.. However, I am getting the following codes:

P0130
P0150
U0001
P2298
P0158

All relate to the Oxygen Sensors(s). I had a lambda sensor replaced in November. But looking especially at P0158 it sounds like the Cat converter has failed....

Any ideas.. Hopefully it'll work but I have attached 5 photos confirming all codes

Could it be that there is a Vacuum Leak? I recall hearing a small hissing sound when the engine is turned off. It would explain why the code reader picks up an issue with the Oxygen sensors....
