HO2S codes
Hey all. I have a 2003 disco that won't pass inspection. I pulled 11 codes at first and now have it down to 4. I have replaced both upstream HO2S sensors and all plugs. I disconnected the battery as instructed. Upon re-connecting and pulling codes i got P0134, P0135, P0155 and P0447. I noticed that the cover on the air filter is cracked at the base and the clip that secures it to the MAF is missing allowing for a loose fit. Can these cause me to pull these codes. I was also told that I need to run the vehicle for at least 100 miles once the replacements have been made to bring the sensors back online. Any help will make a big difference... Thanks in advance.
