5.7 hemi
Hi guys I'm from S.A.
I'VE got a dodge ram 1500 5.7 hemi. Conversion from left hand drive to right hand drive. My problem is it gave me 02 sensor b2s1 circuit high.
Replaced all 4 sensors.
No luck.
Replaced exhaust manifold gaskets no luck.
Replaced all sparkplug no luck.
Redid all injectors.
No luck
Replaced ecu.
No luck.
I'VE had it now
Took out harness checked and replaced faulty wires nothing to do with o2 sensors. Still no luck removed cats and deleted sensors bank1 sensor 2 and bank 2 sensor 2. Still it's there. It starts with pending after a while becomes active. Any advice as to where to check or what to do?

Have you checked the wiring from the PCM to the o2 sensor with a multimeter?
