Oxygen Sensor
Some vehicles have (2) and some have (4) O2 sensors.
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
I have even used a small plumbers propane tank and heat it up and it help get them free.
Sometimes it will take 15 minutes or take a few hours it depends on your luck...
2000 jimmy 4.3ltr v6. were is the o2 sensor bank 1, sensor 3
Bank 2 is passenger side. O2 sensor 1 is threaded into the exhaust system between engine and catalytic converter.
o2 sensor Bank 2 sensor 2
bank 1 is drivers side down stream o2 / bank 2 is drivers side down stream o2
Itis on the driver's side before the catalytic convertor.
what year is the dodge ram? 1999 dodge ram 1500 has the bank 1 o2 sensor located right after the catalytic converter
A/F Sensor for Bank 2 Sensor 1. It is the O2 sensor on the front manifold.
That should be the O2 sensor just before the catalytic converter.
That is the O2 sensor in the pipe after the catalytic converter.
I believe it is before the catallytic converter.
your bank 2 sensor is the o2 sensor on your passenger side exhaust manifold
P1131 = Insufficient switching O2 Bank 1 Sensor 1 Sensor/lean. Could be a B1 S1 O2 sensor going bad.
