What does the Skoda B103E1B fault code mean?
2 Answers
Skoda B103E1B fault code indicates an issue with the fuel level sensor. Here is a detailed analysis of the possible causes: 1. Faulty fuel gauge sensor. 2. Malfunction of the fuel pump control unit (CST engine). 3. Wiring harness issue between the instrument panel and the fuel level sensor. 4. Instrument panel malfunction: Since the fuel gauge sensor has been replaced, this can be mostly ruled out. Use a multimeter to measure according to the circuit diagram. This fault is intermittent, so the fault phenomenon is not observed during each customer visit for inspection. The maintenance personnel can only analyze and repair based on the user's description and fault code, leading to multiple visits for inspection by the customer.
Last time when fixing my friend's Skoda, I encountered the fault code B103E1B. Checking the repair manual revealed it was an issue with the ABS pump's ground circuit. This fault causes the ABS light to illuminate and makes the brake pedal feel noticeably harder when pressed, like stepping on a brick. The most common causes are corrosion of the ground wire near the wheels due to road salt or rust at the chassis ground points. After removing the inner liner of the front right wheel, I found the green ground wire connector covered in green rust. The solution is straightforward: clean the rust off the ground point, replace the terminal with a new one, and apply anti-corrosion grease. However, I must remind you, if you encounter this code, never force-clear it by pulling the fuse. Emergency braking with a failed ABS system can cause the car to fishtail.
