This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer has found a problem with the pump that helps keep the electric parts of a hybrid or electric car cool. It's like if a fan stopped working on a hot day.
The P0CEB code is triggered when the control circuit for the electronics coolant pump A in a hybrid or electric vehicle is detected to have a low voltage condition.
The electronics coolant pump is responsible for circulating coolant to maintain the temperature of the vehicle's electronic components. A low control circuit signal indicates that the pump may not be receiving enough power or there is a fault in the circuit, which could lead to overheating of electronic components.
• Warning light on the dashboard
• Overheating of hybrid/electric vehicle components
• Reduced vehicle performance
• Faulty electronics coolant pump
• Wiring issues such as open or short circuits
• Malfunctioning control module
OBD-II: On-Board Diagnostics, a standardized system for self-diagnostics in vehicles.
Coolant: A fluid used to prevent overheating by transferring heat away from the engine or electronics.
• Check for any blown fuses related to the coolant pump circuit.
• Inspect the wiring and connectors for damage or corrosion.
• Test the electronics coolant pump for proper operation.
• Replace the faulty electronics coolant pump.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the control module if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance checks
• Ensure proper coolant levels
• Inspect electrical connections periodically
Circuit Issue
• Do not ignore the warning light; address the issue promptly to avoid further damage.
• Consult a professional mechanic if you are not confident in diagnosing or repairing the issue yourself.
Check with the vehicle manufacturer for warranty coverage on hybrid/EV components.
This code has become more common with the increased prevalence of hybrid and electric vehicles, as they rely heavily on electronic cooling systems.
High – Failure to address this issue can lead to overheating and damage to electronic components.
Operating a vehicle with this issue may cause safety risks due to potential overheating and reduced vehicle performance.
• Vehicle is in READY mode
• Coolant pump is commanded on by the control module
The electronics coolant pump is typically located near the vehicle's battery or power electronics module.
Q: Can I drive my car with a P0CEB code?
A: It's not advisable to drive with this code active, as it can lead to overheating and damage to the vehicle's electronics.
Q: How can I reset the P0CEB code?
A: After repairing the issue, you can reset the code using an OBD-II scanner. However, ensure the problem is fixed first.
