before changing the sensor try disconnecting the negative battery cable for a minute then hook back up and see if the light comes on. if it does come on you know it wasnt a bogus code. and there is a real problem. most o2 sensors are set to go off at about 20 to 30 thousand miles. Worked also for my 2001 F150.
An O2 (oxygen) sensor measures the amount of oxygen in the exhaust of an engine. The computer uses this information to calculate how much fuel to give the engine.
By measuring the amount of oxygen in the exhaust, the engine computer controls the amount and timing of fuel injected into the engine to maximise power and economy while minimizing emissions.By measuring the amount of oxygen in the exhaust, the engine computer controls the amount and timing of fuel injected into the engine to maximise power and economy while minimizing emissions.
The computer uses the oxygen sensor reading from the exhaust to adjust the amount of fuel injected into the engine.
There really isn't any way to test the oxygen sensor to see if it is good or bad. If your check engine light is on you can take it to Autozone and they will hook it up to computer and if the oxygen sensor is bad, the computer will detect it.
Check engine light,low power, low fuel economy, (when the computer tries to adjust the oxygen sensor readings)highly illegal.Check engine light,low power, low fuel economy, (when the computer tries to adjust the oxygen sensor readings)highly illegal.
The computer will tell you. If you have a "check engine" light, connect a code scanner to see what the computer has detected. If there is a problem with the oxygen sensor the code scanner will display the appropriate problem code.
Code 173 indicates the oxygen sensor is telling the computer that the engine is running rich.
There are two, to do so would be detrimental to your engine and confuse your computer readings onboard.
We are asking how to remove and install a oxygen sensor for a2006 pontiac torrent.
The oxygen sensor, if defective, will give inaccurate readings to the engine management computer and may lead to a rough idle.
The oxygen sensor measures the amount of or lack of oxygen in the burnt exhaust exiting the engine in the exhaust pipe. It will then send a voltage signal to the vehicle computer. The computer uses that signal to control the fuel metering coming into the engine to try and keep the air/fuel ratio at 14.7 parts air to 1 part fuel. This is for emissions and economy reasons.
That is an oxygen sensor, it tells the computer how rich or lean the engine is running on bank 1. The computer uses this info to control how much fuel the engine gets.
