Sensors for the Honda Accord

The Honda Accord utilizes a number of sensors to operate well. These sensors monitor how things like the ABS, emissions, and other systems are functioning and help make adjustments to enhance the performance of your car. Accord sensors are therefore very important to the efficiency of your vehicle, and replacements may be required to keep your Honda functioning properly over the years.

How do sensors work?

The sensors are attached to parts of major vehicle operating systems, such as the cooling, emissions, braking, and combustion systems, as well as an onboard computer. Every second, hundreds of digital messages are sent back and forth between the sensors and the computer to monitor how well the operating systems are performing. Some sensors are also designed to activate actuators and other parts to adjust the settings of an operating system. Otherwise, when a sensor detects something wrong, a light will appear on your dashboard when you start the car or as you drive to alert you to an operating issue.

What types of sensors are there?

Every sensor type has a specific purpose. Some measure the amount of oxygen in the exhaust system, others measure how much traction your tires have on slippery roads, and some sensors warn you when its time to replace a part. Here is a list of some of the main types of sensors in a Honda Accord:

  • Oxygen: Oxygen sensors are used to measure oxygen in the exhaust system to see how well the fuel is burning. The sensor alerts the operating system to let in or to take out oxygen from the combustion process if the Accord is running too lean or too rich to maximize the combustion of fuel. The Honda Accord has upstream and downstream oxygen sensors. The upstream ones are located before the catalytic converter, while the downstream ones are placed just after the catalytic converter.
  • Mass Air Flow: The mass air flow (MAF) sensor is part of the fuel injection system in a Honda Accord. It measures the amount of air going to the cylinders and sends a signal to the throttle to adjust the amount of gas to maintain the proper ratio of gas to air for the combustion of the engine.
  • Manifold Absolute Pressure: On some Honda Accords, a manifold absolute pressure sensor (MAP) is used instead of the MAF sensor. The MAP sensor measures the pressure in the manifold to determine the air density in it. Air density is used to figure out the air flow rate to the fuel injection system.
  • Knock: A knock sensor is used to measure vibrations coming from the motor when it is running. Knocks, also called detonations, mean the engine is running rough, and damage could result if changes aren’t made to the timing. These changes are typically done automatically.
  • ABS: ABS sensors are placed on each brake line to regulate the flow of brake fluid to the cylinders according to the traction measurements of the tires on the road. This helps to prevent the wheels from locking up and sending the Honda Accord into a spin on slippery roads.
