This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is getting a signal that says the temperature sensor in the extra cooling system is too low. It's like a thermometer telling you it's too cold when it shouldn't be.
The P0E83 code is triggered when the vehicle's Engine Control Module (ECM) detects a low voltage signal from the auxiliary cooling system's coolant temperature sensor A. This sensor monitors the temperature of the coolant in the auxiliary cooling system to ensure it operates within the optimal range.
The auxiliary cooling system coolant temperature sensor A is responsible for measuring the temperature of the coolant in the auxiliary cooling system. This sensor sends a voltage signal to the ECM, which uses this information to regulate the cooling system's operation. A low circuit signal indicates a possible issue with the sensor or its wiring, leading to incorrect temperature readings.
• Check Engine Light is on
• Overheating of the auxiliary cooling system
• Poor engine performance
• Faulty coolant temperature sensor
• Damaged wiring or connectors
• Short circuit in the sensor circuit
ECM: Engine Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to verify 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.
• Clear the code and test drive the vehicle to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Toyota Prius
• Chevrolet Volt
• Nissan Leaf
• Regularly inspect and maintain the cooling system.
• Ensure proper coolant levels are maintained.
• Check wiring and connectors for wear and tear.
Sensor Issue
• Do not ignore the Check Engine Light.
• Get the vehicle diagnosed as soon as possible to prevent further damage.
Check with your vehicle manufacturer for specific warranty coverage on emissions-related components.
This code has been reported in hybrid and electric vehicles where auxiliary cooling systems are used for battery and engine management.
Moderate – It is important to address this issue to prevent potential overheating and ensure optimal vehicle performance.
Driving with a malfunctioning cooling system can lead to engine damage and is not recommended.
• Engine at operating temperature
• Vehicle stationary and in park
The auxiliary cooling system coolant temperature sensor is typically located near the radiator or within the engine compartment.
Q: What happens if I ignore this code?
A: Ignoring this code could lead to engine overheating and potential engine damage.
Q: Can I drive my car with this code?
A: It's not recommended to drive for extended periods with this code active, as it may lead to overheating.

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.
