I'm not a mechanic, but I'm pretty sure you have one O2 sensor just before the catalytic converter and one after. The first checks the function of, and regulates, your fuel control unit, and the second checks the efficiency of your catalytic converter. My #1 O2 sensor is screwed into the exhaust pipe about a foot or two before the converter and kind of looks like a spark plug.
On a 2003 Isuzu the O2 sensor is on the driver side of the engine compartment about a foot down from where the exhaust pipe comes out of the header. Just follow the exhaust pipe out of the engine and you will see it. It looks like a spark plug sticking out. It's pretty easy to disconnect the wires, unscrew it and replace it. You will need a 7/8" open end wrench to unscrew it. Good luck. * 1999 Oldsmobile Aurora's actually have 4 O2 sensors, 1 on each header and 1 before, and 1 after the catalytic converter...
the bank 2 is on the driver side i got this info from an Isuzu mechanic
Not a valid code. If it's P0134 the it would be oxygen sensor bank 1 sensor 1, no activity detected.
Not a valid code number, check again. If it's P0131 then it would be a oxygen sensor on bank 1 sensor 1, low voltage.
Passenger side is bank 1 & Driver side is bank 2
Bank 1 is the side that cylinder 1 is on, sensor 1 is downstream and sensor 2 is upstream
Trouble code P0171 means: System Too Lean (Bank 1)
Oxygen sensor heater malfunction (cylinder bank #2, sensor #1)
Drivers side behind the convertor.
02 Sensor Insufficient Switching Bank 1 Sensor 1
If the Trooper has the 3.5L v6, there are 4 SO2 sensors. There are two banks right and left, or bank 1 and bank 2 respectively. Then there is a sensor upstream from the catalytic converter on each bank (sensor 1) , and one down stream (sensor 2).Hope this helps/
If this is a 6VD1 engine, the camshaft position sensor will be located on the very back of the left bank head (on the inside, under the intake manifold). The easiest way to have it replaced or removed is to take off the intake manifold. The sensor is only secured with one 10mm bolt but it is a frustrating thing to put it back on with the intake installed, unless you have very slim hands.
You need to change the upstream sensor
where is the bank1 o2 sensor at and how do i change it please i need your help
Bank 2 is on the passenger side of the vehicle. Sensor 2 is down stream ( behind ) the catalytic converter. Second sensor from the manifold. May have 4 sensors.
Bank 1 sensor 1 is closest to the firewall and located just below the exaust manifold. Easiest to change from under car.
It is a real pain. My suggestion is to take it to a shop.
Bank 1 sensor 1 is upstream bank 1 sensor 2 is downstream
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.
i depends on if its sensor and bank 1 or sensor and bank 2, sensor and bank 1 is in front of the catalytic converter whereas sensor and bank 2 are behind the catalytic converter. just look for the sensor sticking out of the exaust, disconnect and resolder wiring all you really need is a crescent and a soldering iron. i just went through this with my 2001 Mitsubishi eclipse spyder.
Bank one sensor one can be found on the drivers side before the cat. The best way to change the sensor on an '01 XL-7 is to buy an oxygen sensor tool, the socket model works best! These can be found at any auto parts store. I believe they are 22mm?
Bank 1 sensor 2 is the sensor after the catalytic converterBank 1 sensor 2 is the sensor after the catalytic converter
need change knock sensor 2 bank 2 in 2000 lexus rx300
turn counter clockwise to remove, clockwise to install.
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.
