What is C0336?
The DTC C0336 trouble code indicates a malfunction in the vehicle's power steering control module, which is crucial for ensuring proper steering response and handling. When C0336 is triggered, it often points to a problem with the power steering assist system, which may result from sensor failures or wiring issues. This code is particularly common in vehicles like the 2015-2018 Chevrolet Silverado, where drivers may notice difficulties in steering or responsiveness. Ignoring this code can lead to increased steering effort, making it harder to control the vehicle, especially at lower speeds. Additionally, this could cause further damage to the power steering system, resulting in more expensive repairs down the line. If you see C0336, it’s essential to address the issue promptly to maintain safe driving conditions. This code typically means that the power steering system may need immediate attention, and a qualified technician should diagnose the exact problem to prevent worsening conditions.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0336 is present:
- The check engine light remains illuminated, indicating an ongoing issue that needs investigation.
- Steering feels unusually heavy, particularly at low speeds, making maneuvering difficult and potentially dangerous.
- Drivers may experience unexpected steering resistance, particularly during turns or while parking.
- Increased noise from the power steering system, such as whining or groaning when turning the wheel.
- Occasional steering loss, where the power steering assist may fail temporarily, creating a sudden difficulty in steering control.
Possible Causes
Most common causes of C0336 (ordered by frequency):
- The most common cause is a faulty power steering control module, which can occur in about 60% of cases. This module regulates the power steering assist and can fail due to electrical issues or wear.
- Wiring problems, including corroded or damaged connectors, account for approximately 25% of cases. Poor connections can disrupt the signal, leading to a malfunction.
- A malfunctioning power steering motor can also trigger this code, typically due to wear and tear or overheating. Regular maintenance can help prevent this issue.
- Less common but serious causes include a failing steering column assembly, which could lead to complete power steering loss, necessitating immediate repair.
- A rare cause involves software glitches in the vehicle's onboard computer, which may require a software update to resolve the issue.
