Download and install the GeekOBD APP on your smartphone. Connect it to your vehicle’s OBD2 port, and run a scan to retrieve the C0848 code. Review the freeze frame data to understand the conditions under which the code was triggered.
What vehicles are most commonly affected by C0848?
C0848 frequently affects 2010-2016 Chevrolet Silverado, GMC Sierra, and other models within this range. Be sure to check for any manufacturer recalls or Technical Service Bulletins related to this issue.
How can I prevent C0848 from happening again?
Regular vehicle maintenance, including checking wiring and connections, performing alignment checks, and ensuring proper software updates, can help prevent the recurrence of the C0848 code.
What is C0848?
DTC C0848 is a diagnostic trouble code that indicates a malfunction in the vehicle's steering angle sensor circuit. This code is commonly associated with Chevrolet and GMC vehicles produced between 2010 and 2016. When the Electronic Stability Control (ESC) system detects an anomaly in the steering angle sensor, it triggers the C0848 code. This can lead to the ESC system not functioning correctly, resulting in decreased vehicle stability and control. If the sensor is not calibrated or has failed, it could affect how your vehicle responds to steering inputs, especially during adverse weather conditions or emergency maneuvers. Ignoring this code could lead to further complications, including increased wear on the tires and suspension components, as well as potential safety hazards while driving. It’s important to address this issue promptly to ensure your vehicle’s safety features operate correctly.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0848 is present:
- The 'Check Engine' light may illuminate on your dashboard, indicating a fault in the steering system.
- You might experience erratic vehicle handling, especially when turning, as the steering feels unresponsive or overly sensitive.
- The stability control system may not engage properly, leading to a loss of traction during slippery conditions.
- You could notice uneven tire wear due to improper steering angles, which may lead to premature tire replacement.
- The steering wheel may be off-center while driving straight, which can be frustrating and dangerous.
Possible Causes
Most common causes of C0848 (ordered by frequency):
- The most common cause of C0848 is a faulty steering angle sensor, accounting for about 60% of cases. This sensor either gets damaged or fails due to wear and tear.
- Another prevalent cause is poor electrical connections or damaged wiring in the steering angle sensor circuit, which can create intermittent faults.
- Calibration issues after wheel alignments or suspension repairs can also trigger this code. Regular maintenance and checks can help prevent this.
- Less common but serious issues could involve the Electronic Stability Control module itself, which may need replacement if defective.
- A rare cause might be software glitches in the vehicle’s onboard computer, requiring an update or reprogramming.
