This summary uses the existing diagnostic information shown in full below.
This code means that the computer in your car has detected that the voltage from a sensor that checks the power going to a part of the electric motor is too high.
The P0E94 code is triggered when the powertrain control module (PCM) detects a higher than expected voltage from the Drive Motor B Inverter Voltage Sensor B circuit.
The Drive Motor B Inverter Voltage Sensor B monitors the voltage in the inverter circuit for the second drive motor in hybrid or electric vehicles. A 'circuit high' condition indicates that the voltage is above the normal operating range, which could be due to a sensor malfunction, wiring issue, or problem with the inverter itself.
• Check engine light is on
• Reduced vehicle performance
• Potential issues with electric drive functions
• Faulty Drive Motor B Inverter Voltage Sensor
• Wiring issues such as shorts or open circuits
• Faulty inverter or control module
PCM: Powertrain Control Module
Inverter: A device that converts DC to AC power for electric motors
• Use an OBD-II scanner to confirm the code
• Inspect wiring and connections to the sensor
• Test the voltage sensor for proper operation
• Replace the faulty voltage sensor
• Repair or replace damaged wiring
• Replace the inverter if necessary
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance checks
• Ensure proper electrical connections
• 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 until the issue is resolved
Repairs may be covered under warranty if the vehicle is still within the warranty period. Check with the manufacturer.
This code is more common in hybrid and electric vehicles due to the complexity of their electrical systems.
Moderate – It should be addressed soon to avoid potential damage to the vehicle's electric drive system.
Driving with this code may lead to reduced performance and potential safety risks. It is advisable to have the vehicle inspected and repaired promptly.
• Vehicle in 'ON' position
• Engine running
The Drive Motor B Inverter Voltage Sensor is typically located near the inverter assembly, often in the engine compartment.
Q: Can I drive my car with a P0E94 code?
A: It's not recommended to drive with this code as it may lead to further damage or reduced performance.
Q: How do I reset the P0E94 code?
A: After repairs, use an OBD-II scanner to clear the code. If the issue is resolved, the code should not return.
