What vehicles are most commonly affected by B04D0?
The B04D0 code is commonly found in 2016-2020 Ford Fusion models, but it can also affect other makes and models that utilize electronic stability control systems.
How can I prevent B04D0 from happening again?
Regular maintenance, including wheel alignments and inspections of the steering system, can help prevent B04D0. Also, recalibrating the steering angle sensor after major repairs can keep your system functioning correctly.
What is B04D0?
The diagnostic trouble code (DTC) B04D0 refers to a malfunction in the steering angle sensor circuit. This sensor plays a critical role in modern vehicles, particularly in systems that rely on precise steering inputs for functions like stability control and advanced driver-assistance systems (ADAS). When the B04D0 code is triggered, it typically indicates that the steering angle sensor is not providing the expected data to the vehicle's control modules. This issue can manifest in various ways, including warning lights on your dashboard, particularly the stability control light or the check engine light. In the real world, if you own a 2016-2020 Ford Fusion or similar vehicles, you might experience handling problems or a feeling that the steering is off. Ignoring this code can lead to more severe issues, including compromised vehicle safety and performance, especially under adverse driving conditions. Car owners should address this issue promptly to avoid escalating repair costs and ensure the vehicle operates safely and efficiently.
System: B - Body (Airbags, Lighting, Security, Climate Control)
Symptoms
Common symptoms when B04D0 is present:
- The check engine light or stability control light stays illuminated, indicating a potential problem with the steering system.
- Drivers may notice that the steering feels unusually heavy or loose, leading to difficulty maintaining control of the vehicle.
- Fuel economy may decrease by about 10-15% due to the vehicle attempting to compensate for the erroneous sensor data.
- Unusual noises from the steering column might occur, such as clicking or grinding, especially when turning.
- In some cases, the vehicle may enter a limp mode, restricting engine power and limiting speed to ensure safety.
Possible Causes
Most common causes of B04D0 (ordered by frequency):
- The most common cause of the B04D0 code is a faulty steering angle sensor, which accounts for about 60% of cases. This can happen due to wear and tear or electronic failure.
- Another frequent issue is damaged wiring or connectors in the steering angle sensor circuit, which may lead to intermittent signals and trigger the code.
- A miscalibrated steering angle sensor can also cause this code. Regular maintenance, including recalibration after wheel alignment, can help prevent this.
- Less commonly, a malfunction in the vehicle's Electronic Stability Control (ESC) module may be responsible for the B04D0 code, which requires specialized diagnosis.
- In rare cases, software glitches in the vehicle's computer system may lead to false readings from the steering angle sensor.

Diagnostic Steps
Professional B04D0 Diagnosis Process
Follow these systematic steps to accurately diagnose B04D0. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Conduct an initial visual inspection of the steering system
Step 1: Conduct an initial visual inspection of the steering system. Look for any signs of damaged wiring, loose connectors, or corrosion, which may take around 5-10 minutes.
Step 2: Step 2: Use an OBD2 scanner, like the GeekOBD APP, to retrieve the B04D0 code along with any accompanying codes and freeze frame data
Step 2: Use an OBD2 scanner, like the GeekOBD APP, to retrieve the B04D0 code along with any accompanying codes and freeze frame data. This process should take about 10-15 minutes.
Step 3: Step 3: Test the steering angle sensor and its connections using a multimeter or specific diagnostic tools to check for proper voltage and response
Step 3: Test the steering angle sensor and its connections using a multimeter or specific diagnostic tools to check for proper voltage and response. This step may take 20-30 minutes.
Step 4: Step 4: After repairs, perform a system function test to verify that the steering angle sensor is now working correctly and clear any codes
Step 4: After repairs, perform a system function test to verify that the steering angle sensor is now working correctly and clear any codes. This should take about 10-15 minutes.
