Code P1922 Mazda Description
The P1922 diagnostic trouble code (DTC) for Mazda vehicles indicates a Fuel Additive Level Circuit Malfunction. This code is related to the vehicle's fuel additive system, which is responsible for managing the levels of fuel additives in the fuel tank. Fuel additives are chemicals added to fuel to improve its performance, cleanliness, or efficiency. The fuel additive level circuit malfunction can affect the vehicle's performance by causing issues with fuel delivery and combustion, potentially leading to poor fuel efficiency, rough idling, or even engine stalling.
Common Causes of P1922 Mazda
- Faulty fuel additive level sensor
- Wiring or connector issues in the fuel additive system
- Malfunctioning control module
- Contaminated fuel additives
- Corrosion or damage to the fuel tank
Symptoms of P1922 Mazda
- Poor fuel efficiency
- Engine misfires or rough idling
- Engine stalling
- Check engine light illuminated

2. What are the common symptoms of P1922 in a Mazda?
Symptoms may include an illuminated check engine light, poor fuel efficiency, reduced engine performance, or issues with the diesel particulate filter (DPF) regeneration process.
3. What causes the P1922 code to appear?
Potential causes include a faulty fuel additive level sensor, damaged wiring or connectors in the sensor circuit, a low additive level in the tank, or a malfunctioning fuel additive control module.
4. How can I fix the P1922 code on my Mazda?
Check the fuel additive level and refill if necessary. Inspect the wiring and connectors for damage, and replace the fuel additive level sensor or control module if faulty.
5. Can I drive my Mazda with a P1922 code?
Driving with a P1922 code is not recommended, as it may prevent the DPF from regenerating properly, leading to further engine or exhaust system damage.
6. How do I check the fuel additive level in my Mazda?
Consult your vehicle's owner’s manual for the location of the fuel additive tank and follow the instructions to inspect or refill the additive.
7. What tools are needed to diagnose P1922?
You will need an OBDII scanner to read the code, a multimeter to test the circuit, and possibly a repair manual for specific diagnostic procedures.
8. How much does it cost to repair a P1922 code on a Mazda?
Repair costs vary, but replacing the fuel additive sensor may cost $150-$300, while wiring repairs or module replacements could add to the expense.
9. Can a low fuel additive level trigger the P1922 code?
Yes, if the additive level is too low, the system may interpret this as a circuit malfunction and trigger the P1922 code.
10. Does resetting the code clear the issue permanently?
Resetting the code may temporarily turn off the check engine light, but if the underlying issue isn’t resolved, the code will likely return.
