POST UPDATED IN June, 2023
C1141 Code failures by brands
Description of DTC code C1141
Most vehicles are equipped with ABS (Anti-lock Braking System). It is a safety feature that significantly increases braking power, especially under adverse conditions. It is a system that has been designed so that the driver does not depend on special intervention to achieve maximum braking power. Besides, the ABS allows the brakes can work optimally by modulating the pressure to prevent the wheels from locking up under hard braking.
ABS can detect when wheel lockup occurs through a combination of sensors, electronic motors, or servos and control units. Through this process, it can make brake pressure corrections in a fraction of a second.
The Anti-lock Brake System (ABS) Module continuously checks the operation of the Brake Pressure Sensor Switch, if during such monitoring an error in its performance is discovered, the diagnostic code C1141 OBD2 will be set.
Symptoms of fault code C1141
- Check Engine light ON.
- ABS warning lamp
Causes of OBD2 C1141
Reasons to set the C1141 OBDII fault code:
- The Brake Pressure Sensor Switch wiring may be damaged.
- The Brake Pressure Sensor Switch circuit may be open or shorted.
- The Brake pressure sensor switch may be in poor condition.
Possible solutions of the DTC code C1141
To correct DTC C1141 OBD2, try this:
- Consult the Technical Service Bulletins.
- Check the wires associated with the Brake Pressure Sensor Switch for common damage. If you find some conditions such as burns or wear, make repairs.
- Check the Brake Pressure Sensor Switch circuit for any shortages that could cause the malfunction. Through voltage tests, check for an open or shorted circuit, and if one of these conditions is detected, make corrections as applicable.
- Follow the steps to diagnose the Brake Pressure Sensor Switch. If after performing these checks you discover deficiencies on the part of the switch, make replacements.
