Changed my cat in my 2007 Honda Accord also changed my two 02 sensors still am having codes po134 and p1157 .what are the cause
P0134 Air fuel ratio (AF) sensor circuit no activity (Bank 1 Sensor 1)
P1157 Air / Fuel ratio sensor 1 AFS line high voltage
These are both the same code one is generic which is the P0XXX code and the other is manufcatuer code, this is a dosconnection of the sensor any code that is circuit high represent a sensor that is disconnected either at the sensor ,or along its harness , check the harness and its connetion.
