Details of the c1141 OBD Code
Code C1141 relates to a fault in the ABS hydraulic pump motor circuit.
OBD code C1141 means ABS Hydraulic Pressure Differential Switch Input Short Circuit to Battery.
This code is triggered by the ABS module when it detects a short circuit to the battery in the input signal from the hydraulic pressure differential switch.
The hydraulic pressure differential switch is a component in the ABS system that monitors pressure imbalances in the brake system to help prevent wheel lockup during braking.
When a short circuit to the battery is detected in the signal from this switch, the ABS module sets code C1141 to indicate the issue.
