Code P1922 Description
The P1922 diagnostic trouble code (DTC) refers to a Fuel Additive Level Circuit Malfunction. This code is typically found in vehicles equipped with a fuel additive system, which is designed to reduce emissions and improve fuel efficiency. The fuel additive system typically consists of a tank that holds a specific type of additive, such as AdBlue or DEF (Diesel Exhaust Fluid), which is injected into the exhaust system to help reduce harmful emissions.
Common Causes of P1922
- Faulty fuel additive level sensor
- Wiring or connector issues in the fuel additive system
- Low or contaminated fuel additive fluid
- Malfunctioning PCM
- Corrosion or damage to the fuel additive tank
Symptoms of P1922
- Check Engine Light illuminated
- Decreased fuel efficiency
- Rough idling or stalling
- Reduced power output
- Increased emissions output
How to Fix P1922
- Diagnose the issue using a scan tool to determine the exact cause of the malfunction.
- Inspect the fuel additive level sensor, wiring, and connectors for any signs of damage or corrosion.
- Test the fuel additive fluid to ensure it is at the proper level and not contaminated.
- Replace any faulty components, such as the fuel additive level sensor or damaged wiring.
- Clear the DTC and reset the PCM to see if the issue has been resolved.
Cost to Fix P1922
The cost to repair a P1922 code can vary depending on the specific cause of the issue and the vehicle's make and model.
