What is the location of a nox sensor on a 2005 ford taurus


Assuming this is a petrol engine, then it wont have a nox sensor. It will have an O2 sensor, which will be located in the exhaust pipe just before the catalytic converter.

02 kia fail smog high nox


if the engine computer says that you have a slow O2 sensor what it means is that the sensor does not react as quickly as it should and it needs to be replaced. nox is oxides of nitrogen, a product of too lean combustion which causes cylinder temps to go too high. it sounds like replacing O2 sensor will make it happy. engine computer is having a hard time controlling lean/ rich fuel mix because sensor is slow to register changes, needs to have response time in milliseconds or engine computer can't operate properly. O2 sensors do wear out, normal service item. hope that helps

NOX SENOR


I have yet to see a car with a Nitrogen Oxides(NOx) sensor on it. However I have seen Oxygen (O2) sensors. The O2 sensor monitors the remaining amount of oxygen left in your exhaust, and tells your Engine Control Unit(ECU) how much fuel to use. The sensor looks much like a stainless steel spark plug and is found in the exhaust system. Your car being a 1991 it should only have one. It will be up stream of the Catlytic converter, maybe in the Exhaust manifold. cost between 50 and 150$us.
