Are oxygen sensor spacers illegal?

You can use the o2 sensor and trick it, but you'll still be illegal and both principles a & b apply. d.) Since your vehicle will be considered to have it's emissions system tampered with, you best find a place to store that old honking down-pipe because you will not be able to sell or trade the vehicle.

Can a car run without an o2 sensor?

Driving with a faulty O2 sensor means the computer won't be getting the correct reading of the mixture and hence it won't be able to adjust the air-fuel mixture properly. But if your engine starts and runs, and can stay running, it's drivable.

What does a o2 Defouler do?

The defouler pulls the sensor out of the exhaust gas stream and tricks the computer into thinking you you still have a functioning cat.

What are o2 extensions?

These extensions are a plug and play solution for extending the primary oxygen sensors when installing long tube headers. Splicing of the engine harness in order to extend the oxygen sensor wires is no longer necessary. Avoid potential wiring issues and save time with these plug and play extensions.

Is it easier to remove o2 sensor when exhaust is hot?

these are easier to take off when hot vs cold. just be carful not to burn yourself. If you can do as the earlier post mentions (cooling the sensor itself while the pipe is hot/warm), that would be ideal.

Do you need an O2 spacer?

Will a new o2 sensor improve performance?

Those symptoms could also be indications of other problems, but the EPA says that replacing a bad oxygen sensor can improve fuel economy by as much as 40 percent, so clearly that is one place to look if your vehicle develops a greater thirst for gas.

Will a car run better without a catalytic converter?

Without the catalytic converter, your car won't perform as well as it would if it were equipped with one. Without a cat, the oxygen sensors installed before and after the cat will not operate within range. Engine fault codes will be generated, and engine performance will suffer as a result.

How do I get rid of code P0420?

Is there a difference between upstream and downstream O2 sensor?

The upstream sensor monitors the level of pollutants in the engine's exhaust and sends this information to the ECU that continuously adjusts the air-fuel ratio. The downstream sensor measures the level of pollutants passing through the catalytic converter.

Can a bad O2 sensor cause a P0420 code?

Can a bad O2 sensor cause a P0420 code? Yes. A typical catalyst monitor uses the signal from the downstream oxygen sensor to determine catalyst efficiency, and the signal from the upstream sensor is a reference point. As such, failure of either the upstream or downstream oxygen sensor can cause code P0420 to set.

How do I stop my spark plugs fouling?

If you can't avoid a lot of idling or short trip driving, refer to the spark plug supplier's catalog for a spark plug that is one heat range HOTTER than the standard spark plugs specified for your engine. Increasing the heat range slightly can improve fouling resistance by helping the plugs run hotter.

What is the thread size of an oxygen sensor?

Size: M18x1. 5 Also works on M18x1. 5 spark plug threads.

What is a cel eliminator?

CEL Light Eliminator gets rid of the Check Engine Light and will not effect the performance of your vehicle. Now you can adjust the amount of Exhaust CO2 that the O2 Sensor sees to correctly adjust the amount air /fuel ratio which is needed for the vehicle.

What is a spark plug non fouler used for?

The best spark plug non-foulers for cars and trucks prevents the spark plugs from fouling. The purpose of the non-fouler is to act like a sleeve for the spark plug and keep out oil. Gas vapor flows through a small hole in the spark plug non-fouler to ignite and move the engine. Burning oil can cause spark plug fouling.

What is an O2 simulator?

The O2 simulator is a plug-in replacement for the secondary O2 sensor that will provide the PCM with a signal that emulates a healthy cat for testing and off-road purposes. An extremely compact circuit board (. 45 x .

Can you delete O2 sensors with HP Tuners?

yes you can disable rear 02's with HP tuners.

Are all O2 sensors the same?

Even though both O2 sensors are four wire, heated O2 sensors, there are definitely differences that the Motronic can detect. You must use the correct ones, whether oem with the correct length cable and plug, or the correct "universal" equivalent, that will require you to measure and splice your old plug onto it.
