How do you know an oxygen sensor is bad?
Some signs that an oxygen sensor is bad include poor gas mileage, rough idling or stalling, a check engine light illuminating on the dashboard, or a failed emissions test. It is recommended to have the sensor tested by a mechanic to determine if it needs to be replaced.
What color is the signal wire for the oxygen sensor on a 1996 explorer 5.0?
I believe it is the black wire coming from stock o2 sensor. I have tested this wire with votmeter and have seen voltage fluctuation from 200 mv - 900mv. I think this is correct.
What is oxygen tested for?
Take a test tube and put inside it a glowing splint. If the splint relights, the oxygen is present. If not, there is no oxygen.
How do you test throttle position sensor?

The starter battery and alternator have been tested but now car won't start How do I know if I need to replace the solenoid or the oxygen sensor on a 1991 cadillac deville and how is this done?
The O2 (Oxygen Sensor) has nothing to do with the engine not starting. If it will not start you either have no spark or no fuel. If the engine will not turn over, it is either the starter, battery, connections, ignition switch, or starter solenoid. Some starters have the solenoid built into the starter. Test the battery, and all connections. Remove the starter and have it tested at any auto parts store.

You have replaced the throttle sensor map sensor oxygen sensor and crank shaft sensor in our 91 Chevy cavalier and it is still hard to start and jerks a lot and dies what is the problem?
I would say you have to check your coil packs, and ignition module to see if they are firing on all cylinders, and have the correct spark. Anything but a bright blue spark means a weak coil. The ignition module can be tested at some parts stores.

because most combustible gas meters are oxygen dependent and will not provide reliable readings in an oxygen deficient atmosphere .. balls
