Code P1E33 Saturn Description
The P1E33 diagnostic trouble code for Saturn vehicles indicates that the Auxiliary Transmission Fluid Pump Phase U-V-W Current Sensors are not providing plausible readings. In modern vehicles, auxiliary transmission fluid pumps play a crucial role in ensuring smooth gear shifts and optimal transmission performance. These pumps help maintain proper fluid pressure within the transmission system, which is essential for efficient operation.
Common Causes of P1E33 Saturn
- Faulty auxiliary transmission fluid pump
- Malfunctioning phase current sensors
- Wiring issues or electrical faults
- Low transmission fluid levels
- Electronic control module (ECM) malfunction
Symptoms of P1E33 Saturn
- Erratic shifting behavior
- Transmission slipping or hesitation
- Inability to shift gears smoothly
- Transmission system warning light illuminated on the dashboard
- Reduced fuel efficiency due to transmission inefficiency
How to Fix P1E33 Saturn
- Diagnose the P1E33 code using a professional diagnostic scanner to pinpoint the exact cause of the issue.
- Inspect the auxiliary transmission fluid pump, sensors, and wiring for any signs of damage or wear.
- Test the voltage and signals going to the pump to ensure proper operation.
- Replace any faulty components, such as the pump, sensors, or wiring harness, as needed.
- Clear the error code from the vehicle's computer system and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P1E33 Saturn
The typical repair costs for addressing the P1E33 code can vary depending on the extent of the damage and the specific components that need to be replaced. In general, replacing the auxiliary transmission fluid pump, sensors, or wiring harness can range from $300 to $800, including parts and labor. However, additional costs may apply if other transmission components require attention. It is advisable to consult with a qualified mechanic or dealership to obtain a more accurate estimate based on the vehicle's make and model, as well as local labor rates. Keep in mind that labor rates at auto repair shops can vary, with hourly rates typically ranging from $80 to $150.

Frequently Asked Questions about P1E33 Saturn Code
1. What does the OBDII code P1E33 mean on a Saturn?
The code P1E33 indicates that the current sensors for the auxiliary transmission fluid pump’s Phase U, V, or W signals are not plausible, suggesting a fault in the pump's electrical circuit or sensor readings.
2. What are the common symptoms of a P1E33 code?
Symptoms may include a check engine light, reduced transmission performance, erratic shifting, or the vehicle entering limp mode.
3. What causes the P1E33 code to appear?
Common causes include a faulty auxiliary transmission fluid pump, damaged wiring or connectors in the pump circuit, or a malfunctioning control module.
4. Can I drive with a P1E33 code?
While it may be possible to drive with this code, it is not recommended as it could lead to transmission overheating or further damage.
5. How do you diagnose a P1E33 code?
Diagnosis involves inspecting the auxiliary transmission fluid pump, checking wiring and connectors for damage, and using a scan tool to monitor sensor readings and test the pump's functionality.
6. How is the P1E33 code repaired?
Repairs may include replacing the auxiliary transmission fluid pump, repairing damaged wiring or connectors, or reprogramming or replacing the control module if necessary.
7. Is the P1E33 code specific to Saturn vehicles?
While P1E33 is most commonly associated with Saturn vehicles, similar codes might appear in other makes with the same auxiliary transmission system.
8. How much does it cost to fix a P1E33 code?
Repair costs can vary but typically range from $200 to $800, depending on whether the pump or wiring needs replacement and labor rates.
9. Can a dead battery cause the P1E33 code?
A weak or dead battery is unlikely to directly cause this code but could contribute to electrical issues that affect the transmission pump’s operation.
10. Will clearing the P1E33 code fix the issue?
Clearing the code may temporarily turn off the check engine light, but the underlying issue must be resolved to prevent the code from returning.
