They send a false return voltage signal to the ecm (computer).
The ecm then sends too much or too little fuel to the cylinders,
causing poor performance, wasted fuel, overheating, etc.
They don't send a code until they're way off, so it's better to
replace at 75 thousand miles, or so, even if no code's present.
It will pay for itself via better fuel economy and performance.
whan your muscles dont get oxygen the dont work or they dont work properly.
O2 sensors do not work correctly when cold.
No, they usually do not work properly.
air fuel ratio sensors are in the exhaust-they are like oxygen sensors but work differently
No, does not work.
Oxygen sensors do no work well when they are cold so manufactures have installed a heater in the sensor to get it up to speed quickly.
All O2 sensors are located on the exhaust system. Start at the exhaust manifold and work your way backward, and count them.
Oxygen sensors either work or they don't. If they don't, the check engine light will come on and indicate an oxygen sensor problem. If they're fine, none of that will happen.
Try intimidation.
they dont work
well if it doesent work then i dont know ethier
O2 sensors on all vehicles are located in the exhaust system. Start at the exhaust manifold(s) and visually work your way back, you will find them.
