Relay position of the seventh generation Accord oxygen sensor

The position of the Accord sensor is as follows:

1, oxygen sensor: The oxygen sensor is installed on the exhaust pipe to monitor the burnt gas to judge whether the engine is fully burned and whether the mixing degree is too thin or too rich;

2. Wheel speed sensor: Generally, the wheel speed sensor is located on the front wheel brake disc, which mainly collects the speed of the car to judge whether there are signs of slipping. Therefore, there are special sensors to collect the wheel speed of the car to complete this work, which are generally installed on the hub of each wheel. Once the sensor is damaged, abs will fail.

3. Water temperature sensor: The water temperature sensor is installed beside the thermostat to convert the temperature of the cooling water into an electrical signal, increase the fuel injection amount or increase the ignition advance angle at low temperature, prevent explosion at high temperature and delay the ignition advance angle;

4. Intake pressure sensor: generally installed next to the throttle. As the name implies, the intake pressure sensor senses a series of resistance and pressure changes with different engine speed loads, and converts them into voltage signals for ecu to correct fuel injection quantity and ignition timing angle. If it fails, it will cause problems such as difficult ignition, unstable idle speed and weak acceleration.
