P0500 – Vehicle Speed Sensor Malfunction
Let’s break down exactly what the P0500 trouble code means for your Chery and how to fix it.
What Does Code P0500 Mean
The P0500 trouble code is an OBD-II code that indicates a malfunction in the vehicle speed sensor. This sensor is responsible for monitoring the speed of the vehicle and sending this information to the engine control module (ECM). The ECM uses this data to control various functions, such as transmission shifting, cruise control, and traction control. When the vehicle speed sensor malfunctions, it can cause a range of problems, including inaccurate speed readings, erratic transmission shifting, and decreased fuel efficiency.
