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
The noble gas that is isoelectronic with the oxide ion O2 is neon (Ne). Both the oxide ion O2 and the neon atom have 10 electrons.
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.
Neon, if you are talking about an oxygen ion.
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.
rear abs sensor is in the transfer case in the rear tailshaft there 2 sensors 1 is for the speedo and 1 for the abs
