If you cut off your O2 sensors, you will not receive oxygen readings from your car and it will run on simulated values. This occurs when the engine starts running either too rich or lean because the oxygen sensor isnt working properly. If you enjoy off-road racing or have limited engine tuning experience. document.getElementById("ak_js_1").setAttribute("value",(new Date()).getTime()); Hi engineer saab. Bypassing improves engines in reversing unexpected system failures. There are alternatives that can save you money without having to replace the entire catalytic converter. Solder the resistor to the negative and positive wires of the heater circuit. It leads to excess oil coagulants and fails the system. The oxygen sensors are a vital part of measuring the amount of oxygen in the gas. This powerful article teaches you 3 different methods to bypass oxygen sensors. So, you wont be getting the benefits of an actual O2 sensor. Here's the wiring diagram for the RC circuit in the Honda Accord. Where do I buy the dummy 02 sensors for my 1997 camaro that I bought without a cat converter. Dont worry, you can use an RC circuit that functions the same as the O2 simulator. That implies you wont have to look for a compatible sensor. One last suggestion: If you are unsure whether or not to bypass your cars oxygen sensor, we recommend consulting with a professional mechanic or automobile expert. Tape the resistor and all the other circuits to avoid any injury and the short circuit. Step 5: Find the Oxygen/ O2 sensors that resemble a plunge protruding out of the engine exhaust system. This is important to know because some people are misinformed and think it will. The sensor that is near the engine and on the exhaust pipe is called the upstream sensor, whereas the one next to the muffler is called the downstream sensor. Anyway 104K didn't work, so on the way home I stopped and rewired it to 11K ohms. i was wondering what ohm/watt resistor i would need to remove the stock o2 sensor and put the resistor in the heater wires to make a code not pop up? It is pretty simple, and most people can figure out how to do it. Do the same for all of the O2 sensors that you want to remove. This dummy is detected as an actual sensor by the engine computer. So I decided the bypass the o2 sensor entirely. I also worked as a Mechanic for over 3 years to understand Cars' anatomy and how each part contributes to its working.

Other times, it may not be necessary or advisable to bypass the oxygen sensor. were can i get a resistor? Remember bypassing can be done with rear or downstream sensors, not with oxygen sensors before the catalytic converter. obviously the state you are in allows one monitor to report this condition to "pass" their eissions test, other states will fail the vehicle if ANY monitor is not ready. I have an o8 G8 3.6l both cats removed and 07 mini cooper none turbo with headers no cat i have been looking all over for someone to do what you did in your video. If there is no oxygen sensor, the ECU will not know when to adjust the fuel/air mixture, and your car will either run too rich (lots of unburned fuel) or too lean (not enough fuel). Disconnect the negative battery cable from the terminal. They detect the amount of oxygen remaining in exhaust gas to estimate efficiency, fuel mixture and produce critical data for further calculations. Bypassing the oxygen sensor with a dummy can be done. You have to unplug the sensor first and then use connectors to connect the resistor with it. Excessively rich means that theres too much fuel than air in the mixture, and this can result in overheating, and the emissions when the engine runs rich cause more pollution. If you just drove the car, wait for at least 6 hours to let all the components cool down, including the exhaust systems and engine. Extra wire, i used 6ft lengths of wire just incase 820 ohm r Is there anyway I can cheat my car ecu to consume less fuel?
