After failing emissions i found my oxygen sensor unplugged (upstream)
(damn car dealers pull this trick to bring in repair jobs im thinking)
but i digress.. I cannot find where that plugs into. due to the o2 sensor only having a 12 to 16 inch long wire it cant be far but i dont see it anywhere..maybe someone could give me a clue without getting it on a lift. again this is the electrical connector not the sensor end.
thanks

Have your cat. converter checked out. I just had one of these for the same reason in my shop today.

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.

SOURCE: how many o2 sensors does the 94 camaro have.
There is two(2) up top.Left-side of top engine.Right under the windshield level.The other one(1) should be on your right side of the engine,on the top.The other two (2) is in the rear,under the vehicle.One on both sides.

There are two sets of 02 sensors on most cars today. On set is set directly behind the header, one on each side, if it is a V engine. This set is used for the engine's ECU to control timing as well as other variables. The other set is placed on a bung in your Catalytic converter. This 02 sensor is used for emissions purposes only.
