Hello, my ford ranger has a check engine light with the code
This is the only code present. i just changed the driver side pre-catalytic O2 sensor with a brand new bosch unit. The old sensor was rusted on and I had to use my torch on it. The check engine light re-occurred after the car preformed the O2 sensor readiness test. This is a snapshot of the voltages read by the ECU as a drive around. The O2 Bank 2 - Sensor 1 Voltage is constantly at zero. which sensor is this bank 2 sensor 1 ? As I understand it , Bank 2 corresponds to the driver side of the vehicle ? Would this mean the downstream oxygen sensor is named bank 1 sensor 2 ? I am afraid the problem in question may be a wiring fault if indeed the sensor I replaced is reading zero volts. my speedmoter which is on the same harness as this sensor had bad wiring which I had to redo
