Details of the c1148 OBD Code
C1148 indicates a fault in the steering angle sensor circuit on Nissan vehicles.
OBD code C1148 means Pressure Sensor Circuit Malfunction in the ABS system.
This code is triggered by the AntiLock Brake System (ABS) module when it detects a circuit malfunction in the pressure sensor circuit.
The pressure sensor is responsible for monitoring brake fluid pressure within the ABS system to ensure proper operation of the system during braking events.
When this circuit malfunctions, it can lead to issues with ABS functionality and potentially compromise braking performance.
Mechanic’s Tech Notes
Code C1148 relates to a fault in the ABS hydraulic pump motor circuit.
OBDII code C1148 indicates a fault with the ABS hydraulic pump motor circuit.
To diagnose, use a multimeter to check power and ground to the ABS module.
Verify communication between the ABS module and other control modules using a scan tool over the CAN network.
Visually inspect the wiring harness and connectors for any damage, and ensure connector pins are not broken, bent, or corroded.
If no visible issues are found, the ABS module or hydraulic pump motor may need replacement.
Reflashing the ABS module could also be necessary.
FAQ
OBD code C1148 indicates a fault with the ABS RF wheel speed sensor or wiring. Check for open/short circuits, cracked tone wheel, or faulty ABS control module.
Common symptoms of OBD code C1148 include ABS warning light on, engine light on, caused by issues with RF wheel speed sensor, wiring, or ABS control module.
