AP0500 code is a diagnostic trouble code (DTC) titled "Vehicle Speed Sensor (VSS) Malfunction.". This code is triggered when the vehicle's Powertrain Control Module (PCM) or Engine Control TheABS speed sensor ring is the main component of the entire system. It carefully monitors the speed of the wheels and transmits important signals that can alert the system electronically. If the brake is applied heavily, the extra force applied can lock the wheels using the brake discs, which can cause the car to skid on the road. Thetransmission can display symptoms such as delayed shifts, harsh shifts, and limited gear operation if the VSS is malfunctioning. This section will discuss types and functions of speed sensor, signs of bad speed sensor and how to test speed sensor . Catalog. Functions of Bad Speed Sensor. Figure 1. Functions of a bad speed sensor. 2 ABS Module. The ABS control module is a microprocessor that runs diagnostic checks on a vehicle's anti-lock braking system and controls the ABS modulator. It uses data from the speed sensor to manage the valve system in the ABS modulator to restore hydraulic pressure. 3. BuickLeSabre - (IFCAR / Wikipedia) The only major symptom of bad wheel speed sensor in Buick LeSabre is the ABS warning light comes on in the instrument cluster, and the anti-lock braking system is disabled. When the ABS light / comes on in your LeSabre, the anti-lock braking system is disabled. The vehicle can still be braked without ABS. Forvehicles with manual transmissions, the lack of response often takes the form of disconnect between the revving of the engine's RPMs and actual vehicle speed. In this case, the expected acceleration of the vehicle is seemingly much lower than the sound of the engine would imply. Some describe this a transmission "slipping." 2. Odd Sounds VAcJZWh.
