This tells you which oxygen sensor is out, look at your vehicle diagram to see where this sensor is located.
which sensor is for bank 1 sensor 1 on a 2006 nissan xterra
Bank 1 sensor 1 is upstream bank 1 sensor 2 is downstream
Assuming you mean P0135, that would be O2 sensor heater circuit malfunction (bank 1 sensor 1). If the wiring to bank 1 sensor 1 is not damaged, it is probably a bad bank 1 sensor 1 O2 sensor. Replace it.
Bank 1 is the bank that sits closest to the front of the vehicle. Bank one is the bank with cylinder # 1. You have 4 oxygen sensors, (bank 1 sensor 1, bank 1 sensor 2, bank 2 sensor 1 and bank 2 sensor2). Follow the exhaust from the head of bank 1. The first sensor you come to is sensor 1, the second is sensor 2.
bank 1 is upstream bank2 is downstream sensor1 is on cylinder1 side upstream sensor 2 is the other side usually passinger side,bank 2 refers to sensor after converter
It means your sensor heater in Sensor 1 or Bank 1 is malfunctioning. Get it replaced.
Bank 1 Sensor 1- driver's side exhaust pipe Bank 1 Sensor 2-right before catalytic converter Bank 1 Sensor 3- right after catalytic converter Bank 1 Sensor 1- passenger side exhaust pipe Bank 1 Sensor 1- driver's side exhaust pipe Bank 1 Sensor 2-right before catalytic converter Bank 1 Sensor 3- right after catalytic converter Bank 2 Sensor 1- passenger side exhaust pipe
Bank 1 sensor 1 is the first oxygen sensor usually in the exhaust manifold. Usually it needs to be replaced. Sometimes it can just be a bad connection in the plug for the oxygen sensor.
bank 1 is always the head with the number 1 spark plug and the number 1 sensor is always in front of the converters closest to the motor
Trouble code P0134 means:O2 sensor circuit no activity detected (Bank 1 Sensor 1)
