The front sensor is reading wether your air/fuel mixture is correct and computer makes adjustments according to a rich or lean reading from o2 sensor. The rear sensor is reading what comes out from the cat/converter to see if converter is doing is job in removing pollutants.
No. do you mean the front or rear o2? The front might be an A/F sensor. Big difference. But no, there isn't.
(front) sensor 2 is after the cat
The front O2 sensor is located in front of the passenger side right under the fire wall. If you situate yourself on the right front fender of the vehicle, you will see the sensor under the hose that connects to the air filter box. It is connected on the top part of what seems like a catalytic converter. I happen to come accross this while searching for the rear O2 sensor. BTW, do you know where the rear sensor is located?
Hi, The front O2 is located on the front of the exhaust manifold. The rear O2 is located on the front pipe just after the flex. section. Just disconnect the O2 and remove it counter clockwise with a rachet (front) or a key (rear). Don't forget to disconnect your battery a few minutes to rest your ECM.
You did not specify which O2 sensor it is. Is it sensor 1 bank 1, sensor 2 bank 2, sensor 2 bank 1, or sensor 1 bank 2. There are four O2 sensors on a mazda 626
The oxygen sensor for a 1996 Infiniti I30 has 3 wires. The car actually has two O2 sensors, a front and a rear. Both sensors are the three-wire type.
Remove the vacuum hose from the O2 sensor. Remove the wiring harness. Remove the O2 sensor retaining screws. Reverse the process to install the new O2 sensor.
It is the O2 sensor screwed into the front of the catalytic converter
replace rear o2 sensor.
The O2 sensor on the 1994 accord dx, lx, or ex is the same, and there are two O2 sensor on the 1994 accord, fornt and the rear. Fornt one is located on the top and it is right on the header and the rear O2 sensor should locate on your cat converter right in the middle of your car. So check which sensor that you need and replace it.
for a 97-03 grand prix there is a front and rear o2 sensor. bank 1 sensor 2 is the sensor located on the exhaust near the catalytic converter (cat) also known as the REAR sensor... bank 1 sensor 1 is located on the back of the engine on top of the exhaust manifold or headers would be the street term. thats the FRONT sensor.
if you have the F22B1 (97EX 2.2lVTEC) engine , the front 02 sensor is located below the exhaust manifold on the front of the engine, it has a wiring harness attached to it, and is screwed into the exhaust pipe from the top, before the Catalytic converter. the rear O2 sensor is located AFTER the catalytic converter, and is attached similarly.
