Code P1479 Dodge Description
The P1479 code for Dodge vehicles indicates a Transmission Fan Relay Condition. This code is related to the transmission's cooling system, specifically the relay that controls the fan responsible for keeping the transmission fluid at an optimal temperature. The transmission fan is crucial for preventing overheating, which can lead to damage and decreased performance.
Common Causes of P1479 Dodge
- Faulty relay: The most common cause of the P1479 code is a faulty transmission fan relay. Over time, relays can wear out or fail, preventing the fan from operating correctly.
- Wiring issues: Problems with the wiring connecting the relay to the fan can also trigger this code. Frayed wires, loose connections, or corrosion can disrupt the electrical signal and prevent the fan from functioning.
- Fan motor failure: If the fan motor itself fails, it will not be able to cool the transmission fluid properly, leading to overheating and triggering the P1479 code.
- PCM (Powertrain Control Module) issues: In some cases, problems with the PCM that controls the transmission fan relay can cause this code to be triggered. Issues with the PCM's software or hardware can prevent the relay from receiving the correct signals.
Symptoms of P1479 Dodge
- Overheating transmission: One of the most common symptoms associated with this code is an overheating transmission. This can result in erratic shifting, slipping gears, and ultimately transmission failure if not addressed.
- Check engine light: The P1479 code will trigger the check engine light on the dashboard, alerting the driver to a problem with the transmission fan relay.
- Burning smell: A burning smell coming from the engine bay or transmission area can indicate that the transmission fluid is overheating due to a malfunctioning fan relay.
- Transmission fluid leaks: In some cases, the transmission may start leaking fluid due to overheating, which can further exacerbate the issue.

- Repair or replace wiring: If wiring issues are the cause of the problem, the damaged wires will need to be repaired or replaced. This may require tracing the wiring back to its source and addressing any areas of concern.
- Replace the fan motor: If the fan motor is found to be the issue, it will need to be replaced. This may involve removing other components to access the fan motor and installing a new one.
- Clear the code: Once the repairs have been completed, the code will need to be cleared from the vehicle's computer system. This can be done using an OBD-II scanner or by disconnecting the battery for a period of time.
