This code means that the second fan in your car, which helps keep the engine cool, is having trouble working properly.
The P1DDE code indicates a malfunction in the secondary cooling fan's operation at its first stage.
The P1DDE code is triggered when the Engine Control Module (ECM) detects an issue with the operation of the second cooling fan at its first stage. This can be due to electrical issues, mechanical faults, or sensor problems that affect the fan's ability to operate as intended.
• Engine overheating
• Cooling fan not operating
• Illuminated check engine light
• Faulty fan motor
• Blown fuse or faulty relay
• Wiring issues or poor connections
