Honda Accord is a popular car model and has been in production since 1976. The 1997 model was equipped with a speed sensor that is responsible for measuring the speed of the vehicle. The speed sensor is a critical component of the vehicle’s electronic system and is located in the engine compartment. This article provides a comprehensive guide to the 1997 Honda Accord speed sensor wiring diagram.
What is a Speed Sensor?
A speed sensor is an electronic device that measures the speed of a moving object. In the case of a Honda Accord, the speed sensor measures the speed of the vehicle. The speed sensor is typically located near the transmission of the vehicle and is connected to the transmission control module (TCM).
The TCM uses the information from the speed sensor to help regulate the shifting of the transmission. If the speed sensor fails, it can cause shifting problems, engine stalling, and other issues.
