The most common reason the ESP light illuminates is because of a faulty ABS sensor or ABS ring. It can also be caused by issues like a bad throttle body, brake pedal switch, or steering sensor. If it's blinking while driving on a slippery surface, it's working correctly. The ESP works together with the ABS. Dirty tone ring Bad ABS module BRAKE light: Low brake fluid Low brake pads Parking brake set Any ABS fault (illuminated in tandem with ABS light on certain vehicles) Depending on the year of the vehicle, most ABS codes can be read by OBDII-based diagnostic tools on '96+ vehicles. To summarize, here are 14 reasons why the ABS and traction control lights come on: ABS module failure; Computer issues; Blown fuse; Dysfunctional wheel-speed sensor; Low tire pressure; A defective steering angle sensor; Low brake fluid; Faulty steering rack; Defective pump and valve; Bad wheel alignment; Dirt and debris; Low battery voltage There are several faults that could be behind an ESP warning light on your dash. These are: Faulty Wheel ABS Sensors. The sensors in the wheels provide the ABS control unit with information about each wheel's speed. This allows the ABS to make the necessary corrections if one or more of the wheels slips. Driver 81. 139K subscribers. 154K views 8 years ago.

The ABS wheel sensor works together with the stator ring to monitor wheel speed rotation. If the stator ring is damaged, it can cause a malfunction of the ABS. Check to ensure the stator ring is not damaged or dislodged, resulting in missing teeth activating the ABS light. The aim of this review was to study why, despite large investments in research and development, algae biodiesel is still not price competitive with fossil fuels. Microalgal production was confirmed to be a critical cost item (84 up to 93 %) for biodiesel regardless of the production technology. Techno-economic assessment revealed the main cost drivers during mass cultivation. It is argued that 1. Faulty ABS speed sensor The ABS control unit receives data regarding each wheel's speed from the wheel sensors. When one or more wheels begin to slide, the ABS control unit monitors this data and makes the required adjustments. Just yesterday, I noticed that my ABS/BAS and ESP warning lights were lit up on my instrument cluster. I also noticed that once the car was parked and I wanted to put my top up, the switch to put the top up would flash red and the top would not go up as normal. Reasons Why The ABS and Traction Control Light Is On. If both lights are on, the ABS wheel speed sensor might be bad or it could be the ABS reluctor ring. It may also be a bad steering angle sensor, wiring issues, a blown fuse or low brake fluid. The problem may also be a bad ABS control module or low battery voltage. k7Z7I.
