This code means there's a problem with the sensor that checks the temperature of the coolant used to keep the electronics cool in a hybrid or electric vehicle.
The P0CEE code indicates an issue with the circuit of the coolant temperature sensor for the electronics in a hybrid or electric vehicle. This sensor helps monitor and maintain the proper temperature of the electronics by measuring the coolant temperature.
The Hybrid/EV Electronics Coolant Temperature Sensor A is responsible for providing the powertrain control module (PCM) with information regarding the temperature of the coolant used to keep the electronic components at an optimal temperature. A fault in this circuit can lead to improper temperature regulation, potentially affecting vehicle performance.
• Check engine light illuminated
• Overheating of electronic components
• Reduced performance of hybrid/EV systems
• Faulty coolant temperature sensor
• Damaged wiring or connectors
• Faulty PCM
PCM: Powertrain Control Module
OBD-II: On-Board Diagnostics II
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the coolant temperature sensor for proper operation.
• Replace the faulty coolant temperature sensor.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the PCM if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regular maintenance checks
• Ensure proper coolant levels
• Inspect wiring and connectors periodically
Sensor Issue
• Do not ignore the check engine light.
• Get the vehicle inspected by a professional if unsure.
• Regularly check coolant levels and condition.
Check with the vehicle manufacturer for specific warranty coverage on hybrid/EV components.
This error code has been more common as hybrid and electric vehicles have become more prevalent, highlighting the importance of electronic cooling systems.
Moderate – Addressing this issue promptly can prevent potential damage to electronic components.
Driving with this code may lead to overheating of electronic components, which can cause further damage or safety risks.
• Engine at operating temperature
• Vehicle stationary
The coolant temperature sensor is typically located near the electronics cooling system, often near the radiator or coolant lines.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to overheating of electronic components, which may cause further damage and reduce vehicle performance.
Q: Can I drive my car with this code?
A: It's not recommended to drive for extended periods with this code, as it may lead to overheating and potential damage to the vehicle's electronics.

Fitment Required · Vehicle-fitment part
Relevant when coolant-temperature and warm-up faults indicate a thermostat-related issue.
Coolant-temperature and warm-up faults often lead to thermostat testing and replacement.
Thermostats are vehicle-specific and should be matched by engine and housing style.
