CEL code
Just got a 96 V6 with a dual exhaust already fitted by previous owner. I get an error code P0156, which means downstream o2 sensor fault B2S2.
Puzzle to me is..... this car did not originally have dual cats fitted, so there should not be 2 downstream o2 sensors connected to the PCM.
Scan tool voltage reads 1.275V which is above rich limit for sensor control.[sm=helpout.gif]
Any ideas whats going on??
