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 tells it where the electric motor is. It's like if a video game controller couldn't tell where the joystick was pointing.
The code indicates that the voltage signal from the drive motor position sensor is lower than expected, suggesting an issue with the sensor or its circuit.
The drive motor position sensor provides feedback on the position of the drive motor's rotor. A 'Circuit A Low' code indicates that the signal voltage from this sensor is below the threshold set by the vehicle's manufacturer, potentially due to a wiring issue, a faulty sensor, or a problem with the vehicle's control module.
• Check Engine Light is on
• Reduced vehicle performance
• Unusual noises from the electric motor
• Faulty drive motor position sensor
• Damaged or corroded wiring/connectors
• Faulty control module
Drive Motor: An electric motor that provides propulsion for the vehicle.
Position Sensor: A device that detects the position of a component, such as a motor rotor.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage or corrosion.
• Test the drive motor position sensor for proper operation.
• Replace the drive motor position sensor.
• Repair or replace damaged wiring/connectors.
• Reprogram or replace the control module if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly inspect and maintain electrical connections.
• Avoid exposure to moisture and corrosive environments.
• Follow manufacturer service schedules.
Sensor Issue
• Have the vehicle inspected by a professional if the Check Engine Light comes on.
• Avoid driving the vehicle aggressively until the issue is resolved.
Check with the vehicle manufacturer for warranty coverage on hybrid or electric drive components.
This code is more common in hybrid and electric vehicles due to their reliance on electric drive systems.
Moderate – It should be addressed soon to prevent further damage to the vehicle.
Driving with a malfunctioning drive motor sensor can lead to reduced performance and efficiency, potentially affecting vehicle safety.
• Vehicle in 'Ready' mode
• Drive motor engaged
The drive motor position sensor is typically located near the electric motor within the vehicle's powertrain.
Q: Can I drive my car with this code?
A: It's possible, but not recommended as it may lead to reduced performance and efficiency.
Q: Will this code affect my car's fuel economy?
A: Yes, it can lead to reduced efficiency, especially in hybrid or electric vehicles.
