Code P1E37 Description
The diagnostic trouble code P1E37 indicates that the auxiliary transmission fluid pump inverter is experiencing high temperatures. This component is responsible for regulating the flow of transmission fluid in hybrid vehicles, ensuring smooth operation of the transmission system. When the inverter reaches high temperatures, it can lead to overheating, which can cause damage to the transmission pump and other related components.
Common Causes of P1E37
- Malfunctioning cooling system for the auxiliary transmission fluid pump inverter
- Low transmission fluid levels
- Electrical issues within the inverter
- Clogged transmission fluid filter
- Faulty transmission fluid pump
Symptoms of P1E37
- Illumination of the check engine light on the dashboard
- Transmission slipping or delayed shifting
- Overheating of the transmission fluid
- Unusual noises coming from the transmission system
- Reduced fuel efficiency
How to Fix P1E37
- Begin by diagnosing the exact cause of the high temperature in the auxiliary transmission fluid pump inverter using a diagnostic scanner.
- Check the cooling system for any leaks or blockages and repair as necessary.
- Inspect the transmission fluid levels and top up if low, ensuring the correct type of fluid is used.
- Test the electrical components of the inverter for any faults and replace any damaged parts.
- If the transmission fluid pump is faulty, replace it with a new one to restore proper function.
Cost to Fix P1E37
The cost of repairing the auxiliary transmission fluid pump inverter high temperature issue can vary depending on the specific cause of the problem and the extent of the damage. On average, the repair costs for this issue can range from $200 to $800, including parts and labor. However, it's important to note that diagnosis time and labor rates at auto repair shops can vary, so it's recommended to obtain quotes from multiple sources to get a more accurate estimate.
