This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has detected a problem with the sensor that checks how hot the part controlling the electric motor is getting.
The P0E23 code is triggered when the vehicle's powertrain control module (PCM) detects an issue with the circuit of the temperature sensor for the drive motor inverter. This sensor monitors the temperature to ensure the inverter doesn't overheat.
The drive motor inverter temperature sensor is responsible for monitoring the temperature of the inverter, which converts DC to AC power for the electric motor. If the sensor or its circuit is malfunctioning, it can lead to improper temperature readings, potentially causing the inverter to overheat or not function correctly.
• Check Engine Light is on
• Reduced vehicle performance
• Overheating inverter
• Faulty temperature sensor
• Damaged wiring or connectors
• Faulty powertrain control module (PCM)
Inverter: A device that converts DC power to AC power.
PCM: Powertrain Control Module, the computer that controls engine and transmission functions.
• Use an OBD-II scanner to verify the code.
• Inspect the wiring and connectors for damage.
• Test the temperature sensor with a multimeter.
• Replace the temperature sensor if faulty.
• Repair or replace damaged wiring or connectors.
• Replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Screwdrivers

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance checks
• Ensure proper cooling system function
• Avoid high-load driving conditions
Sensor Issue
• Have the vehicle inspected by a professional.
• Avoid driving in high-temperature conditions until repaired.
Check with the manufacturer for warranty coverage on hybrid components.
This code has become more common with the increase in hybrid and electric vehicles, highlighting the importance of inverter cooling systems.
Moderate – It should be addressed soon to avoid potential inverter damage.
Driving with this code may lead to reduced performance and potential overheating, which could be unsafe.
• Vehicle at operating temperature
• Engine running
The drive motor inverter temperature sensor is typically located near the inverter assembly, often in the engine bay.
Q: Can I drive with a P0E23 code?
A: It's not recommended to drive for long periods with this code, as it may lead to overheating and damage.
Q: How do I reset the P0E23 code?
A: After repairs, use an OBD-II scanner to clear the code, but ensure the issue is resolved first.
