it's running rich and hunting in live data it says lambda sensor diagnosis status not ok and the fault code description of the 0134 says bank 1 sensor 1 activity not detected. usually if it's the narrow band sensor i have no problem checking it but this broadband sensor is there any way to check the sensor's health? the heater get's voltage and there is 2.78v on the black wire while the engine is running and 1.5v koeo
anybody has experience with this system?
