The most common cause of B0175 is a faulty fuel level sensor, which can cost between $150 and $300 to replace. Other causes include damaged wiring, costing similarly for repairs, and rare issues with the ECM, which can be more expensive to address.
Can I drive my car with B0175 or should I stop immediately?
While it's possible to drive with B0175, it's not advisable as it may lead to running out of fuel unexpectedly. It's best to address the issue promptly to ensure safe driving.
How can I diagnose B0175 myself using GeekOBD APP?
To diagnose B0175 using the GeekOBD APP, first connect your device to the vehicle's OBD2 port. Use the app to scan for codes and review any freeze frame data. Check for any accompanying trouble codes that may provide more context about the issue.
What vehicles are most commonly affected by B0175?
B0175 commonly affects vehicles like the 2008-2012 Ford F-150 and the 2007-2014 Chevrolet Silverado. Always check for any recalls or Technical Service Bulletins (TSBs) related to these models to stay informed about potential issues.
How can I prevent B0175 from happening again?
Regular maintenance, including checking wiring and connections, can help prevent B0175. Keeping your fuel system clean and ensuring proper fuel type can also contribute to the longevity of your fuel level sensor.
What is B0175?
The diagnostic trouble code (DTC) B0175 indicates an issue with the fuel level sensor circuit, primarily affecting the fuel gauge readings in vehicles. This code is often triggered when the engine control module (ECM) detects an abnormal voltage signal from the fuel level sensor. The fuel level sensor is responsible for providing accurate data about the fuel tank's content, which is crucial for the engine management system. If this sensor malfunctions, it can lead to incorrect fuel readings on the dashboard, potentially causing drivers to run out of fuel unexpectedly. This code is commonly found in various models, including the 2008-2012 Ford F-150 and the 2007-2014 Chevrolet Silverado. Ignoring this code may lead to further complications, such as fuel system inefficiencies and, in severe cases, engine performance issues due to improper fuel management. Regular diagnostics and timely repairs can prevent these complications, ensuring that your vehicle runs smoothly and efficiently.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B0175 is present:
- Check engine light illuminates, indicating a fault in the fuel level sensor circuit.
- Fuel gauge displays incorrect levels, often showing empty when the tank is full or vice versa.
- Inconsistent fuel economy, with potential drops of 10-15% due to improper fuel management.
- Warning messages or alerts on the dashboard related to fuel levels.
- Difficulty starting the engine due to fuel delivery issues if the sensor drastically fails.
Possible Causes
Most common causes of B0175 (ordered by frequency):
- The most common cause is a faulty fuel level sensor, which has about a 70% likelihood of being the issue. Over time, this sensor can wear out due to exposure to fuel and environmental conditions.
- Another common cause is damaged wiring or loose connections in the fuel level sensor circuit, leading to erratic readings. This can occur from corrosion or physical damage.
- A third cause could be a malfunctioning fuel pump, which may prevent the sensor from reading fuel levels accurately. Regular maintenance can help prevent this.
- Less common but serious causes include a faulty ECM that misinterprets signals from the fuel level sensor, which requires a more complex diagnostic approach.
- In rare cases, a software glitch may trigger this code. Updating the vehicle’s software through a dealer could resolve this issue.
