if you get under the car and follow the exaust from the back of the motor there should be a cadaldic converter. the back one is after the converter towards the back of the car. hope that helps.
1st o2 senor is between exhaust. 2nd o2 sensor is under shifter
in the rear
In the intake duct before the air filter
One wire, and it's purple.
Neon has 10 electrons. Anions isoelectronic with neon are F-, O2-, N3-. Cations isoelectronic with neon are Na+, Mg2+, Al3+
there are NO speakers in the "rear" doors of a Neon.
Oxide ion O2- is isoelectronic with neon.
Neon, if you are talking about an oxygen ion.
O2- has 10 electrons with the configuration of neon or 1s2 2s2 2p6
it could be contaminated or the heating circuit is burned out. replace it.
O2 sensors are located in the exhaust system.
Primary (bank 1 sensor 1) O2 sensor slow or not responding. Wiring or connector to senor or O2 sensor defective. Exhaust leak possible but not likely.
