Code P1926 Description
The P1926 diagnostic trouble code (DTC) relates to the Fuel Additive Level Circuit Range/Performance. This code indicates that there is an issue with the fuel additive system in the vehicle. Modern vehicles are equipped with fuel additive systems to ensure optimal performance and reduce emissions. The fuel additive system typically includes components such as a fuel additive tank, pump, level sensor, and control module.
Common Causes of P1926
- Faulty Fuel Additive Level Sensor: A faulty level sensor in the fuel additive system can trigger the P1926 code.
- Wiring Issues: Damaged or corroded wiring connecting the fuel additive system components can cause communication errors and trigger the code.
- Defective Control Module: A malfunctioning control module that controls the fuel additive system can lead to the P1926 code.
- Low Fuel Additive Level: If the fuel additive tank is low on additive, it can trigger the code as the system expects a certain level of additive.
Symptoms of P1926
- Check Engine Light: The most common symptom associated with the P1926 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A malfunctioning fuel additive system can lead to reduced fuel efficiency as the engine may not be running optimally.
- Engine Misfires: The engine may experience misfires or hesitation during acceleration due to improper fuel additive levels.
- Rough Idle: The vehicle may exhibit a rough idle or stalling at idle due to issues with the fuel additive system.
How to Fix P1926
- Diagnose the Issue: Use a scan tool to read the DTC and diagnose the specific cause of the P1926 code.
- Inspect Wiring: Check the wiring connecting the fuel additive system components for any damage or corrosion, and repair or replace as needed.
- Test Fuel Additive Level Sensor: Test the fuel additive level sensor for proper operation and replace if faulty.
- Replace Control Module: If the control module is deemed faulty, replace it with a new one to resolve the issue.
- Refill Additive: Ensure that the fuel additive tank is filled to the appropriate level to prevent the code from reoccurring.
Cost to Fix P1926
The cost of repairing a P1926 code can vary depending on the specific cause of the issue and the vehicle's make and model. On average, the repair cost for this issue can range from $150 to $500, including parts and labor. It's important to note that diagnostic time and labor rates at auto repair shops can vary, so it's recommended to check with local shops for a more accurate estimate. Keep in mind that rates may be higher at dealerships or in metropolitan areas, while independent shops may offer more competitive prices.
