This summary uses the existing diagnostic information shown in full below.
This means that the car's computer thinks the engine is not getting as much fuel as it should be. It's like when you expect a full glass of juice but only get half.
The engine control module (ECM) monitors the amount of fuel being injected into the engine. If it detects that the fuel quantity is lower than expected, it triggers this code.
The P2DDE code is set when the ECM detects that the fuel injection quantity for a specific cylinder is lower than the expected value. This could be due to a malfunction in the fuel injection system or related components.

Engine Performance
• Avoid driving the vehicle until repaired
• Consult a professional mechanic
• Regularly check fuel system components
Check with your vehicle manufacturer; fuel system components may be covered under warranty.
This code is relatively common in vehicles with high mileage or poor maintenance history.
Moderate – Addressing this issue promptly can prevent further engine damage.
Ignoring this code can lead to increased emissions and potential engine damage.
• Engine at operating temperature
• Vehicle in idle or low-speed conditions
Fuel injectors are located on the engine, typically near the intake manifold.
Q: Can I drive with a P2DDE code?
A: It's not recommended to drive with this code as it can lead to engine damage.
Q: How do I clear a P2DDE code?
A: The code can be cleared with an OBD-II scanner after the issue is resolved.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.
