Code P1930 Lincoln Description

The P1930 diagnostic trouble code for Lincoln vehicles indicates that the fuel additive level in the vehicle's system is too low or empty. This code is typically associated with vehicles equipped with a diesel engine that requires the use of a diesel exhaust fluid (DEF) additive to reduce emissions. The DEF is injected into the exhaust stream to convert harmful nitrogen oxides into harmless nitrogen and water vapor. When the additive level is too low or empty, the vehicle may not be able to effectively reduce emissions, leading to increased pollution levels and potential damage to the engine and exhaust system.

P1930 indicates that the fuel additive level in the vehicle’s fuel system is too low or empty, which can impact emissions and performance.

2. What are common symptoms of the P1930 code?

Symptoms may include the check engine light turning on, reduced engine performance, and potential failure to regenerate the diesel particulate filter (DPF) in diesel models.

3. What causes the P1930 code to appear?

Common causes include low or empty fuel additive levels, a malfunctioning fuel additive tank sensor, or wiring/connectivity issues in the additive system.

4. Can I drive my Lincoln with the P1930 code active?

It’s possible to drive with this code temporarily, but neglecting it could lead to DPF clogging, reduced engine performance, and increased emissions.

5. How do I fix the P1930 code on my Lincoln?

Refill the fuel additive tank with the correct additive and clear the code. If the issue persists, inspect the additive level sensor and wiring for faults.

6. How do I know if my Lincoln uses a fuel additive system?

Fuel additive systems are typically found in diesel models with a DPF to aid in filter regeneration. Consult your owner’s manual for details.

7. What type of fuel additive should I use to resolve the P1930 code?

Only use the manufacturer-recommended fuel additive, as using the wrong type can damage the system or fail to clear the code.

8. How do I reset the P1930 code after refilling the additive tank?

You may need to use an OBDII scanner to clear the code or perform a system reset according to the vehicle’s service manual.

9. What happens if I ignore the P1930 code?

Ignoring this code can lead to DPF clogging, engine derating, higher emissions, and potential costly repairs down the line.

10. Can a faulty fuel additive tank sensor cause the P1930 code?

Yes, a faulty sensor may incorrectly detect low additive levels and trigger the P1930 code even if the tank isn’t empty.
