When this code is triggered, it means that the powertrain control module (PCM) has detected a voltage signal from the heater coolant pump control circuit that is higher than the specified range.
Common Causes of B269D
- Faulty heater coolant pump
- Short circuit in the heater coolant pump control circuit
- Corrosion or damage to electrical connectors
- Issues with the powertrain control module (PCM)
- Wiring issues or loose connections
Symptoms of B269D
- Lack of heat in the cabin
- Overheating of the engine
- Check Engine Light illuminated on the dashboard
