P1E2D Chevrolet Code - Auxiliary Transmission Fluid Pump Phase V Current Sensor Circuit Low Voltage
Quick Answer
The power inverter module, often referred to as the drive motor generator power inverter module, contains three motor control modules and the hybrid powertrain control module. Common causes include Program Power Inverter Module, Faulty Power Inverter Module, Power Inverter Module harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1E2D Chevrolet Description
Each motor control module operates its respective drive motor based upon hybrid powertrain control module commands. Each motor control module controls its respective motor through the sequencing actuation of high-current switching transistors called insulated gate bipolar transistors. Each motor operates utilising 3-phase alternating current AC electricity. Each insulated gate bipolar transistor operates a single phase of the drive motor generator. Each phase is individually identified as U, V and W. Each motor control module monitors the current of each phase in order to detect out of range current conditions.
Because each individual motor's phase circuits are electrically joined together, the phases normally flow about the same amount of current. The motor control module performs a mathematical calculation to verify that the phase current sensors are accurate. If the U-V-W phase current sensors indicate about the same amount of phase current, the sum of the calculation should be near zero. If the U-V-W phase currents are not similar, this DTC will set.
What are the Possible Causes of the DTC P1E2D Chevrolet?
- Program Power Inverter Module
- Faulty Power Inverter Module
- Power Inverter Module harness is open or shorted
- Power Inverter Module circuit poor electrical connection
How to Fix the DTC P1E2D Chevrolet?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?

Frequently Asked Questions about P1E2D Chevrolet Code
1. What does the OBDII code P1E2D mean on a Chevrolet?
The code P1E2D indicates a low voltage issue in the Auxiliary Transmission Fluid Pump Phase V Current Sensor Circuit.
2. What are the symptoms of the P1E2D code?
Symptoms may include transmission performance issues, warning lights like the check engine light, and possible erratic shifting or reduced vehicle performance.
3. What causes the P1E2D code to appear?
Common causes include a malfunctioning auxiliary transmission fluid pump, damaged wiring or connectors, a faulty current sensor, or a problem with the vehicle's PCM (Powertrain Control Module).
4. Can I drive my Chevrolet with the P1E2D code active?
It is not recommended, as the code can lead to transmission performance issues that may cause further damage or unsafe driving conditions.
5. How do you diagnose the P1E2D code?
Diagnosis involves using an OBDII scanner to read the code, inspecting the wiring and connectors for damage, testing the auxiliary transmission fluid pump, and checking the current sensor for proper operation.
6. How do you fix the P1E2D code on a Chevrolet?
Repairs may include replacing the auxiliary transmission fluid pump, repairing or replacing damaged wiring, replacing the current sensor, or reprogramming or replacing the PCM if necessary.
7. What tools are needed to repair the P1E2D code?
Basic tools include an OBDII scanner, a multimeter for testing circuits, and possibly specialty tools for accessing or replacing the auxiliary pump or sensor.
8. How much does it cost to repair the P1E2D code?
Repair costs vary but can range from $100 to $500 or more, depending on whether simple wiring repairs are needed or if components like the pump or PCM require replacement.
9. Can low transmission fluid cause the P1E2D code?
While low transmission fluid itself doesn't directly trigger this code, it can cause related issues that may contribute to the auxiliary pump malfunctioning.
10. Is the P1E2D code common in Chevrolet vehicles?
This code is relatively uncommon but may appear in models with auxiliary transmission fluid pumps, particularly if there are wiring, sensor, or pump issues.
