The bank one sensor, on your Suzuki Grand Vitara XL7 4 x 4 is located on the front of the transmission. The sensor will have 3 wires coming from it.
P0135 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1) Bank one is drivers side. Sensor 1 is the one closest to the engine.
P/S exhaust, after the manifold but before the catalytic converter, at the back of the motor, behind the valve cover.
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 sensor 1 is upstream bank 1 sensor 2 is downstream
Bank 2 indicates the bank containing cylinder #2. Bank one contains cylinder #1. Passenger side cylinder #'s are 2,4,6. Driver's side's are 1,3,5. Make a diagram for yourself, it helps a lot for not forgetting. Ok. Now that you know where bank 2 is. The GV v6 has 4 O2 sensors, 2 on each pipe that comes directly out of each manifold on either side of engine. On each side, one sensor is above or 'upstream' of the little pre catalytic converter, one is below or 'downstream'. The upstream sensor is #1, the downstream sensor is #2. Therefore Bank 2 sensor 1 is the upstream or top sensor on the passenger side bank of cylinders. This concerns the O2 sensors, which I assume is what you are referring to.
Bank one sensor two refers to the oxygen sensor. The bank one sensor two oxygen sensor is on the front side of the engine, after the catalytic converter.
Is this bank 2 sensor 1 or sensor 2?
bank 2 sensor 2 front bank after the cat
which sensor is for bank 1 sensor 1 on a 2006 nissan xterra
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
The bank 1, sensor 3, O2 sensor would be the O2 sensor post cat.
