This code means there's a problem with the sensor that checks how hot the part of the car that controls the electric motor is getting. It's like a thermometer that's not working right.
The P0E29 code is triggered when the vehicle's control module detects an issue with the temperature sensor in the drive motor inverter. This sensor monitors the temperature to ensure the inverter operates within a safe range.
The drive motor inverter temperature sensor measures the temperature of the inverter, which is responsible for converting DC power from the battery to AC power for the electric motor. If the sensor's readings are outside the expected range, the control module sets the P0E29 code.
• Check Engine Light is on
• Reduced vehicle performance
• Potential overheating of the inverter
• Faulty drive motor inverter temperature sensor
• Wiring issues or poor connections in the sensor circuit
• Malfunctioning inverter control module
Inverter: A device that converts DC power to AC power.
Sensor: A device that detects or measures a physical property and records, indicates, or otherwise responds to it.
• Use an OBD-II scanner to confirm the P0E29 code.
• Inspect the wiring and connections to the temperature sensor.
• Test the sensor for proper operation using a multimeter.
• Replace the faulty temperature sensor.
• Repair or replace damaged wiring or connections.
• Replace the inverter control module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly inspect and maintain electrical connections.
• Ensure proper cooling system maintenance.
• Use OEM parts for replacements.
Sensor Issue
• Avoid driving the vehicle until the issue is resolved to prevent damage.
• Consult a professional mechanic for accurate diagnosis and repair.
Check with the vehicle manufacturer for warranty coverage on hybrid components.
This code has become more common with the increased use of hybrid and electric vehicles, where inverter temperature management is crucial.
Moderate – Addressing this issue promptly can prevent further damage to the inverter.
Driving with this issue may lead to overheating, which could cause further damage or safety risks.
• Vehicle at operating temperature
• Inverter under load
The drive motor inverter temperature sensor is typically located near the inverter assembly, which is often found in the engine compartment or under the vehicle.
Q: Can I drive my car with a P0E29 code?
A: It's not recommended to drive with this code active, as it may lead to overheating and further damage.
Q: How do I know if the sensor is faulty?
A: A faulty sensor may give erratic readings or no readings at all. Testing with a multimeter can confirm its condition.
