The 2002 Honda Accord’s engine starts by sending a signal to the car’s 02 sensor. This sensor monitors the air pressure in the fuel system and sends a signal to the engine control unit (ECU) when the pressure drops below a certain level. This helps to prevent pinging or knocking during cold starts, and also keeps gas from being wasted during regular fuel-ups.
What is an 02 Sensor and What Does it Do in a Car
An 02 sensor is a type of sensor that is used in cars to monitor air pressure in the tires. It is also called a tire pressure monitoring system or TPMS. The purpose of the 02 sensor is to prevent tire blowouts and low air pressure, which can lead to accidents.
When the 02 sensor detects a low air pressure, it sends a signal to the car’s computer. The computer then changes the settings on the car’s tire pressure monitoring system (TPMS) so that it will alert the driver when the air pressure in one or more of the car’s tires falls below a certain level.
The TPMS can also warn the driver when there is too much air pressure in one or more of the car’s tires. This might be caused by a nail in the tire, a flat tire, or a problem with the TPMS itself.

How an 02 Sensor Works
An 02 sensor is a sensor that is located in the exhaust system of a car. It uses an infrared light to measure the amount of oxygen in the air. The sensor helps to control the engine’s fuel mixture so that the car runs smoothly and without smoke.
When to Replace an 02 Sensor in a Car
An 02 sensor is a type of sensor that is used in many cars to monitor the air pressure in the tires. Over time, the sensor can wear out and need to be replaced. When this happens, the car will not be able to start or it may experience other problems.
There are two types of sensors: primary and secondary. Primary sensors are the original sensors that were installed in your car when it was new, while secondary sensors are usually replacements.
If you are experiencing problems with your car, it is important to check the air pressure in all of your tires. If one tire has low air pressure, it is likely that the other tires also have low air pressure. In order to diagnose the problem, you will need to replace the 02 sensor.
What to Do If Your Car Doesn’t Start After replacing the 02 Sensor
If your car doesn’t start after you replace the 02 sensor, there are a few things you can do to try and solve the problem.
The first step is to check to see if the car has any power. Try turning the key in the ignition and checking for power at the battery. If there is no power, you may need to replace the battery.
If you still have no luck, you can try disconnecting all of the cables from the car and test them one by one. If one of the cables is bad, it may be causing the car not to start.
If none of these solutions work, you may need to take your car into a mechanic for a more detailed inspection.
Conclusion
If you’re like most people, you probably don’t know what an 02 sensor does in a car. In short, it’s used to detect the level of carbon monoxide in the air outside your car. If the level of carbon monoxide is high enough, your engine may not start. So if you ever notice that your car doesn’t start when you get out in the morning (and there’s noxious gas smell coming from inside), it might be worth checking to see if there’s an02 sensor problem.
