This summary uses the existing diagnostic information shown in full below.
This code means that a sensor in the car that checks how hot a part of the electric motor system is getting is saying the temperature is too high. It's like a thermometer telling you it's really hot.
The P0E26 code indicates that the temperature sensor for the drive motor inverter is reporting a higher than expected voltage, suggesting a high temperature reading.
The drive motor inverter temperature sensor monitors the temperature of the inverter, which is responsible for converting DC power to AC power for the electric motor. A 'Circuit High' condition means the sensor is sending a voltage signal that is higher than the expected range, indicating a potential issue with the sensor or the circuit.
• Illuminated check engine light
• Reduced vehicle performance
• Overheating warning light
• Limited driving range
• Unusual noises from the motor area
• Faulty drive motor inverter temperature sensor
• Wiring issues such as short circuits or open circuits
• Faulty inverter
• Poor electrical connections
• ECU/PCM issues
Inverter: A device that converts DC electricity to AC electricity.
ECU: Engine Control Unit, the computer that controls engine functions.
• Scan the vehicle for codes and freeze frame data.
• Inspect the wiring and connections to the temperature sensor.
• Test the temperature sensor with a multimeter.
• Check the inverter for overheating or damage.
• Verify the ECU/PCM functionality.
• Replace the drive motor inverter temperature sensor if faulty.
• Repair or replace any damaged wiring or connectors.
• Replace or repair the inverter if necessary.
• Update or reprogram the ECU/PCM if needed.
• OBD-II scanner
• Multimeter
• Screwdriver set
• Wire repair tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly check and maintain the cooling system.
• Inspect electrical connections periodically.
• Avoid overloading the vehicle's electrical system.
Sensor Issue
• Do not ignore the check engine light.
• Have the vehicle inspected by a professional.
• Avoid driving the vehicle excessively until repaired.
Check with your vehicle manufacturer for warranty coverage on hybrid system components.
This code has become more common with the increase in hybrid and electric vehicles, reflecting the importance of temperature management in these systems.
Moderate – While not immediately dangerous, it should be addressed to avoid potential damage to the inverter or motor.
Driving with a known defect could lead to further damage or reduced safety performance.
• Vehicle at operating temperature
• Stable power supply to the sensor
The drive motor inverter temperature sensor is typically located near the inverter assembly, often within the engine compartment of hybrid or electric vehicles.
Q: Can I drive with a P0E26 code?
A: It's not recommended to drive extensively with this code as it may lead to further damage.
Q: How do I reset the P0E26 code?
A: After repairs, the code can be cleared using an OBD-II scanner.
