Oxygen Sensor If you look inside the wheel wells behind the fender liner, right about where the frame is one O2 sensor, the other is underneath the truck about half way back in relation to the transmission. If you see where the exhaust joints together, you went about 6" too far.
When you start looking at the O2 sensors, they are normally numbered something like "Bank 1 Sensor 1" Bank 1 is on the passenger side; Bank 2 is on the driver's side. Sensor 1 is the upstream sensor (near the frame, between the block and the cat) and Sensor 2 is near the Y-pipe (downstream of the cat).
Normally it is the upstream sensors (sensor 1) that go first. They see the harshest conditions. You will need; Oxygen Sensor Socket Anti-Seized Penetrating Oil Sometimes it will take 15 minutes or take a few hours it depends on your luck…
in the exhaust manifold toward the firewall its the hard one!!!
16518- P0134 O2 Sensor Circ.,Bank1-Sensor1 No Activity Detected 16519- P0135 O2 Sensor Heater Circ.,Bank1-Sensor1 Malfunction
O2 Sensor Stuck Lean (Bank1 Sensor1).
that is the oxygen sensor on the exhause manifold.
Bank 1 is the passenger side of your V6 in a Ford Ranger Sensor 1 is somewhere close to the engine before the exhaust enters the catalytic converter
It depends on which sensor, O2/camshaft,etc. The O2 sensor is a straight metal sensor that is screwed into the exhaust. There is an upstream/bank1-sensor1 or down stream/bank1-sensor2 after the catalytic converter. A camshaft sensor is an L shaped, usually black sensor that is installed into the head closest to the firewall(bank1).
The diesel has two. Sensor one is closer to the engine.
Bank 1 should be the side of the engine cylinder #1 is on.
There are two oxygen sensor, follow the exhaust coming out of the engine. one in the front and one in the back of the engine. if you engine code p0135 bank1 these is oxygen is located between firewall and engine. or p0755 oxygen located in front of the engine
You need get a special socket for oxygen sensors. Disconnect the harness, use the socket to remove the sensor. Reinstall a new one. Tighten the sensor the proper torque. Put some dielectric grease on the harness, reinstall the harness. Reset the ECU.
Passengers side, after the catalyst.
p0132 O2 Oxygen Sensor Circuit High Voltage (Bank1, Sensor1). You have a bad oxygen sensor ( most likely ) and according to the code it is the forward most sensor on the bank 1 side of the vehicle. If you don't know which one that is have the parts store show you, it is the same sensor for both side bank 1, but different from sensor 2 usually.
