It might have fallen off, got a hole in it, or been removed for more horsepower, but without it, your car will always have a check engine light if you still have a functioning O2 sensor. Solder the resistor to the negative and positive wires of the heater circuit. Fuel consumption is a major problem for many drivers, but there are some clever techniques to improve your gas mileage. The sensors are part of the exhaust system. We will cover a couple of different methods and explain the pros and cons to each one, and we will also explain why you might want to bypass the oxygen sensor. The oxygen sensors are a vital part of measuring the amount of oxygen in the gas. The extender helps to keep the sensor cooler and reduces the amount of exhaust gas that comes in contact with the sensor. Fix it into the electrical houses and connect it with the electrical wiring. Much like the O2 simulator and dummy, the resistor will also trick the computer with signals that tell the O2 sensor is working perfectly. An example of data being processed may be a unique identifier stored in a cookie. There are alternatives that can save you money without having to replace the entire catalytic converter. This means that your car will not be able to adjust the air/fuel mixture to compensate for any changes in altitude or weather conditions, and it may cause your car to run poorly or even damage the engine. Im excited to share some of the techniques Ive discovered that can help reduce your fuel consumption and help you save money on gas.
