In most cases, NO. There are exceptions to the rule on Asian cars. Nissans really hate fuel injection cleaners. But on American cars, if you use a bottle of fuel injection cleaner, and your O2 sensor goes bad, its not because of the FI cleaner. Its because the sensor has gone bad, or something else is wrong with the car. If your O2 sensor is bad, I recomend doing a tune up, plugs, wires, PCV valve, air filter, oil change, and the O2 sensor.
What else can I help you with?
What controls the converter on a 1999 escort?
The oxygen sensors control the amount fuel in the engine and if it is making too many emissions the oxygen sensors will cut back on the fuel or if they are worn out they will increase the amount of fuel. The catalytic converter will eventually get plugged up if the Oxygen sensors are bad. The oxygen sensors control the converter.
Is there a fuel injection oxygen sensor on a 1998 ford rangerAnd where is it?
There are several 02 sensors in that vehicle depending on which engine you have. They are all threaded into the exhaust system at various points.
Does fuel injection cleaning affect the 02 sensors?
It shouldn't, but if your injectors were dirty, then the O2 sensors probably are too.
What do the upstream oxygen sensors do on a 05 mustang?
Upstream oxygen sensors send a signal to the PCM which adjusts the fuel mixture ( air / fuel ratio )
How do you fix the fuel running too rich?
If the fuel is running too rich in a car, it would be a good idea to adjust the EFI or Electronic Fuel Injector (carburetor). It would also be a good idea to make sure that all of the air cleaners and oxygen sensors are clean and functioning properly.
Where is air fuel sensor located on Toyota RAV4 2002?
air fuel ratio sensors are in the exhaust-they are like oxygen sensors but work differently
Why would you get a lot of black smoke from your Audi A4?
Black smoke means the engine consumes too much gas - possible problem with fuel injection. Is your check engine light on? It could also be a problem with oxygen sensors.
How many o2 sensors does a 1997 mercury mountaineer have?
There are a total of ( 4 oxygen sensors ) according to the engine wiring schematic for the 1997 Mercury Mountaineer in my Haynes repair manual ( 2 oxygen sensors are " upstream " sensors used by the PCM to adjust the air / fuel ratio of the engine ) ( 2 oxygen sensors are " downstream " sensors / catalyst monitors )
Where is oxygen sensor equipment typically used?
Oxygen sensors are located in teh exhaust stream, they do not directly measure the air or the fuel entering the engine. But when information from the oxygen sensor is coupled with other information from oher sources, it can be used to indirectly determine the air-to-fuel ratio. In addition, to enabling electronic fuel injection to work efficiently, this emission control technique can reduce the amounts of both unburnt fuel and oxides of nitrogen from entering the atmosphere.
Can fuel additives affect oxygen sensors?
The fuel additive container should say "O2 sensor safe".
How many o2 sensors on 2002 Toyota Highlander v6?
There are 3 oxygen sensors on this vehicle. Some of the Highlanders with California emissions have 2 fron Air/Fuel Ratio sensors and one rear Oxygen sensor.
Does a crank shaft sensor control the fuel injection timing?
There are multiple sensors used to control fuel injection in an engine. Depending on the year, make, and model or the vehicle, there could be upwards of 20 sensors used to determine the amount of fuel injected into an engine.For most modern cars, the primary sensors, which the computer uses to determine fuel needs, are the Oxygen (O2), the Mass Air Flow (MAF), and the Crank/Cam positions sensors.The O2 sensor measures the amount of oxygen in the post combustion exhaust stream, and determines if the engine is running lean (not enough fuel) or rich (too much fuel).The MAF sensor measures the amount of air coming in through the vehicle's intake manifold, and determines the amount of fuel needed for the volume of air the engine is moving.The Crank/Cam position sensor measures the position of either the crankshaft or the camshaft, and tells the computer if the engine is running or not; if this sensor is not working, the fuel injectors will not deliver fuel to the engine.
