This means there's a problem with the part of the car that helps control how much fuel goes into one of the engine's cylinders. It's like a faucet that's stuck open, letting too much fuel flow in.
The code P319E indicates that the electrical circuit controlling the hydrogen injector for cylinder 6 is experiencing a high voltage condition.
The P319E code is triggered when the Engine Control Module (ECM) detects a high voltage condition in the low side circuit of the hydrogen injector for cylinder 6. This could be due to a short to voltage, faulty wiring, or a malfunctioning injector.
• Check engine light on
• Poor engine performance
• Increased fuel consumption
• Faulty hydrogen injector
• Short circuit in the wiring
• Faulty Engine Control Module (ECM)
Injector: A device that introduces fuel into the engine's combustion chamber.
ECM: Engine Control Module, the computer that controls engine functions.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the hydrogen injector for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the faulty hydrogen injector.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Engine Performance
• Avoid driving the vehicle until repaired to prevent further damage.
• Consult a professional mechanic for accurate diagnosis.
Check with the vehicle manufacturer for specific warranty coverage on emissions-related components.
This code is specific to hydrogen fuel cell vehicles and has become more common as these vehicles gain popularity.
High – Immediate attention is required to prevent engine damage.
Operating a vehicle with a malfunctioning injector can lead to increased emissions and potential safety risks.
• Engine at operating temperature
• Vehicle in park or neutral
The hydrogen injector is located on the engine's cylinder head, specifically for cylinder 6.
Q: Can I drive with a P319E code?
A: It's not recommended to drive with this code as it can lead to further engine damage.
Q: How can I clear the P319E code?
A: After repairs, use an OBD-II scanner to clear the code, but ensure the issue is resolved first.
