Four, two on each side. Driver side is referred to as bank one, passenger side bank two. Senor one is before the catalyst converter, sensor two after.
right side
If it has a bank two, It would be on the passenger side. I have a 1994 K2500, it only has one oxygen sensor.
Assuming the engine is a 4.3L, bank 1 would be on the drivers side.
What side is bank two chrysler 2.5
pass. side rear
Bank 1 is drivers side where number 1 cylinder is. Sensor 3 is post cat/converter, drivers side
Driver side, after converter.
"bank 1" refers to the side of the engine with the forward most cylinder(cylinder#1).... all bank 1 is that side of the vehicle... bank 2 is the other side and sensor 1 is first in line from front to back
Bank 1 = Cylinder 1/Drivers Side Bank 1 Sensor 1 = Upstream (before cat) Drivers Side Bank 1 Sensor 2 = Downstream (after cat) Drivers Side Bank 2 Sensor 1 = Upstream (before cat) Pass Side Bank 2 Sensor 2 = Downstream (after cat) Pass Side
