Code P1E2F Saturn Description
The P1E2F diagnostic trouble code (DTC) for Saturn vehicles specifically relates to the Auxiliary Transmission Fluid Pump Phase V Current Sensor Performance. This code indicates that there is a malfunction or performance issue with the current sensor that monitors the operation of the auxiliary transmission fluid pump. The auxiliary transmission fluid pump plays a crucial role in maintaining proper fluid pressure and circulation within the transmission system. The current sensor is responsible for monitoring the electrical current flowing through the pump, ensuring that it is operating within specified parameters.
Common Causes of P1E2F Saturn
- Faulty auxiliary transmission fluid pump
- Malfunctioning current sensor
- Wiring issues or electrical faults in the sensor circuit
- Poor electrical connections or corrosion
- Internal transmission problems affecting pump operation
Symptoms of P1E2F Saturn
- Erratic shifting or hesitation during gear changes
- Harsh or delayed transmission engagement
- Transmission slipping or jerking
- Overheating of the transmission
- Illumination of the Check Engine Light
How to Fix P1E2F Saturn
- Diagnose the issue by using a scan tool to retrieve the DTC and perform a thorough inspection of the auxiliary transmission fluid pump, current sensor, and related components.
- Test the current sensor's electrical circuit for proper voltage, resistance, and continuity to determine if the sensor is functioning correctly.
- Inspect the auxiliary transmission fluid pump for proper operation and replace it if necessary.
- Check for any wiring issues, corrosion, or poor connections in the sensor circuit and repair as needed.
- Clear the DTC from the vehicle's computer after completing the repair and test drive the vehicle to ensure proper transmission operation.
Cost to Fix P1E2F Saturn
The typical repair costs for addressing the P1E2F code on a Saturn vehicle can vary depending on the specific cause of the issue and the extent of the repairs needed.

Frequently Asked Questions about P1E2F Saturn Code
1. What does the OBDII code P1E2F mean for a Saturn vehicle?
P1E2F indicates an issue with the Auxiliary Transmission Fluid Pump Phase V Current Sensor, meaning the sensor's performance is outside its expected range.
2. What are the common symptoms of code P1E2F in a Saturn?
Symptoms may include transmission overheating, erratic shifting, reduced fuel efficiency, or the illumination of the check engine light.
3. What causes the P1E2F code to appear?
The code can be triggered by a faulty current sensor, wiring issues, a malfunctioning auxiliary transmission fluid pump, or an issue with the vehicle's powertrain control module (PCM).
4. Can I drive my Saturn with the P1E2F code active?
Driving with this code is not recommended, as it could lead to transmission overheating or damage if the pump isn’t operating correctly.
5. How is the P1E2F code diagnosed?
A mechanic will typically use a scan tool to check for related codes, inspect the wiring and connectors, and test the auxiliary pump and its current sensor.
6. How can I fix the P1E2F code on my Saturn?
Repairs may include replacing the auxiliary transmission fluid pump, repairing damaged wiring, or replacing the current sensor.
7. Will clearing the P1E2F code solve the issue?
Clearing the code may temporarily turn off the check engine light, but the underlying issue must be repaired to prevent the code from returning.
8. How much does it cost to fix the P1E2F code?
The cost depends on the exact issue but can range from $100 for a simple wiring repair to $500 or more for replacing the auxiliary transmission fluid pump.
9. Can a faulty PCM cause the P1E2F code?
Yes, although it’s less common, a malfunctioning PCM could misinterpret sensor data and cause the code.
10. What preventative maintenance can help avoid the P1E2F code?
Regularly check your vehicle’s transmission fluid levels, inspect wiring for damage, and ensure the auxiliary transmission pump and related components are functioning correctly.
