They are at the base of the exhaust manifolds, just above the flanges. I think you can get to them from the top by reaching under the firewall.

Bank 2 sensor 2

Do you know which cylinder on the engine is number 1? Bank 1 is always the side where the number 1 cylinder is located. Bank 2 would be the opposite side. Sensor 1 is always the oxygen sensor nearest to the engine. Sensor 2 is the sensor after the catalytic converter.

What is a P 133 code on a 1998 Camaro indicating?

There is no code P133...that is not enough numbers. If you mean P0133, then that is "Oxygen Sensor Bank 1 Sensor 1 Slow Response". This is USUALLY caused by O2 sensor contamination. The O2 sensor itself is not responding as quickly as it should to changes that the computer makes to the injector pulse width.

Sometimes the O2 sensor is just plain worn out, however the engine should be checked for things like leaking valve seals (burning oil) or a leaking head gasket (burning antifreeze) that could be contaminating the O2 Sensor.

- Cylinder bank number one is the bank that contains number one cylinder.

Cylinder #1 on right side.

- The first oxygen sensor in cylinder bank # 1 is numbered O2 Sensor 1/1.
- The second oxygen sensor in cylinder bank # 1 is numbered O2 Sensor 1/2.
- A third oxygen sensor in cylinder bank # 1 would be numbered O2 Sensor 1/3.
- The first oxygen sensor in cylinder bank # 2 is numbered O2 Sensor 2/1.
- The second oxygen sensor in cylinder bank # 2 is numbered O2 Sensor 1/1.

- If a V-6 or V-8 vehicle only uses one downstream Heated Oxygen Sensor (HO2S) it is numbered O2 Sensor 1/2, even if it uses two upstream HO2S.

Where's the bank 1 sensor 1 located at my toyota sienna 2007, i know there are 3 sensors in bank 1 and 1 sensor in bank 2 if you can give me the image or view where they are located i really appreciate...

O2 sensors location is broken down like this. The bank refers to which side of the motor the sensor is on. Bank 1 is the same side of the engine as the number one cylinder. Bank 2 is the other side of the motor. Sensor refers to either before the cat or after the cat.

Bank 1 sensor 1 would be the O2 on the side of the motor that the number one cylinder is on and before the cat.

The number one cylinder is on the back side of the motor (the side closest to the firewall). The O2 sensor will be in the exhaust pipe near the exhaust manifold.

Getting random misfire on my 99 v6 camaro. its not the coils..

Ok, I agree; this is not your basic misfiring cycle. I will list the possible areas of concern:

1. Damaged Up or down stream O2 sensor harness or sensor device.(this can be intermittent so check the harness for shorts on each O2 sensor)
2. Faulty Injector or clogged fuel rail supply manifold.(inspect these areas for clogs)
3. Burned exhaust valves(this will be the worst case scenario)
4. Collapsed catalytic converter(If you are smelling fuel, this could be the culprit)
5. Stuck or blocked EGR valve/passages. Check the hose to be sure it has not collapsed, as well.
6. Damaged Camshaft position sensor.(check the sensor harness first for shorts)
7. Defective PCM(This is very rare, but possible if all the above check out ok)

Check all that i have stated above for faults. Let me know the result and post any questions that you may have.

OBD code P0146 O2 sensor circuit no activity. Bank 1 Sensor 3 what should I check first.

ok first off if there is no connectivity you will need to confirm this by testing the leads to the O2 sensor itself, try to back probe them with a T pin so that you don't disturb the plug too much so that you can rule out a fuilty plug connection, make sure you have voltage, I would assume this is a 4 wire O2 sensor which means that its a heated sensor meaning it has a heater in it to jump start the collection of data @ the sensor.if you have voltage check the plug it self it there is voltage on the O2 sensor side on the plug then you have a bad O2 sensor

I have a 2002 Z28 Camaro that I am currently trying to get to pass emissions inspection. I have just replace both upstream O2 sensors, and I am still getting a P1133 code. I cant figure out the problem,...

P1133 - Insufficient Switching on a Pre-Cat sensor, Bank 1 Sensor 1
Is the exhaust stock? or do you have long tube headers?? The long tube headers cause the heat-up time on the o2s to be longer (causing the switch time to take longer (p0133/p0155)).

Otherwise - insufficient switching of the o2...exhaust leak possibly near the sensor... sometimes a blown head gasket can cause this code too.
