If the codes are telling you O2 sensor, then look there. The EHA has probably nothing to do with it, or possibly just triggered the already problematic sensor.
Used EHA's are a complete crapshoot. Pressures have no indication for proper function unfortunately, so you either test it by the seat of your pants, or flow test each injector to check for proper fuel quantities and work your way backwards if it does not meet specs.
