Common Questions
What does C0350 mean and how does it affect my car?
The C0350 code indicates a malfunction in the steering position sensor circuit. This issue can lead to heavy steering or unresponsive steering, posing a safety risk while driving. If left unresolved, it could escalate into more serious steering problems.
What are the most common causes of C0350 and how much does it cost to fix?
Common causes include a faulty steering position sensor, damaged wiring, or issues with the ECM. Repair costs typically range from $150 to $400, depending on the exact issue and required parts.
Can I drive my car with C0350 or should I stop immediately?
It is recommended to stop driving your vehicle if you receive the C0350 code. Continuing to drive can lead to a complete loss of steering assistance, which poses a serious safety risk.
How can I diagnose C0350 myself using GeekOBD APP?
To diagnose C0350 using the GeekOBD APP, connect the app to your vehicle, run a full OBD2 scan, and analyze any codes and freeze frame data. Look specifically for the C0350 code and any accompanying codes that might provide additional insights.
What vehicles are most commonly affected by C0350?
C0350 is commonly found in vehicles like the 2010 Chevrolet Malibu, 2011 GMC Terrain, and other GM models from 2007-2015. These vehicles may have specific recalls related to steering issues.
How can I prevent C0350 from happening again?
Regular maintenance, such as inspecting connections and cleaning the steering position sensor area, can help prevent C0350 from recurring. Additionally, addressing any steering issues promptly can prevent further complications.
What is C0350?
The Diagnostic Trouble Code (DTC) C0350 indicates a problem with the steering position sensor circuit. This code is commonly found in vehicles manufactured by General Motors, including Chevrolet and GMC models, particularly those from the late 2000s to the early 2010s. The steering position sensor is crucial for the electronic power steering system; it constantly monitors the position of the steering wheel and sends this data to the vehicle's engine control module (ECM). When the ECM detects a discrepancy in the sensor's readings, it triggers the C0350 code. This can lead to various issues, including difficulty steering, the steering wheel feeling heavy, or the steering system becoming unresponsive. Ignoring this code can lead to more severe steering issues and potential safety hazards, making timely diagnostics and repairs essential. If you experience symptoms related to this code, it's important to address them promptly to avoid further damage to the steering system and ensure safe vehicle operation.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0350 is present:
- The check engine light may illuminate continuously, indicating a fault in the steering system.
- Drivers may notice that the steering feels unusually heavy or unresponsive, especially during low-speed maneuvers.
- Fuel economy could decrease by 10-20% due to the power steering system working harder to compensate for the faulty sensor.
- There may be a grinding or clicking noise coming from the steering column when turning the wheel.
- Drivers might experience erratic steering behavior, where the steering wheel does not return to the center position after a turn.
Possible Causes
Most common causes of C0350 (ordered by frequency):
- The most common cause of C0350 is a faulty steering position sensor, with an estimated 70% likelihood of being the root issue. This sensor can wear out over time due to exposure to dirt and moisture.
- Another potential cause is damaged wiring or connectors in the steering position sensor circuit. This might occur due to corrosion or physical damage, leading to intermittent connectivity.
- A third cause could be a malfunctioning electronic control module (ECM), which misinterprets the signals from the steering position sensor. Regular system checks can help prevent this issue.
- Less common but serious causes include a complete failure of the power steering system, which, if not addressed, could lead to steering loss.
- A rare cause might be a software issue within the vehicle's onboard computer system, affecting the data readouts from the steering position sensor.
