This summary uses the existing diagnostic information shown in full below.
The car's computer thinks one of the sensors that tells it how hot the engine is, is getting a signal that's too high. It's like a thermometer showing a temperature that's way too hot.
The Engine Control Module (ECM) has detected a high voltage signal from the Engine Coolant Temperature (ECT) Sensor 3 circuit, indicating a possible fault.
The P01E6 code is triggered when the ECM receives a signal from the Engine Coolant Temperature Sensor 3 that is higher than the expected range. This sensor is responsible for providing the engine's temperature data to the ECM, which uses this information to adjust fuel mixture, ignition timing, and other parameters for optimal engine performance.
• Check Engine Light is on
• Engine may run rough
• Poor fuel economy
• Faulty Engine Coolant Temperature Sensor 3
• Wiring issues such as short circuits or open circuits
• Poor electrical connection at the sensor or ECM
ECM: Engine Control Module
ECT: Engine Coolant Temperature
• Use an OBD-II scanner to confirm the code
• Inspect the wiring and connectors for damage
• Test the Engine Coolant Temperature Sensor 3 for proper operation
• Replace the faulty Engine Coolant Temperature Sensor 3
• Repair or replace damaged wiring or connectors
• Clear the code and test drive to ensure the issue is resolved
• OBD-II Scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Silverado
• Ford F-150
• Toyota Camry
• Regularly inspect and maintain wiring and connectors
• Ensure coolant levels are adequate
• Perform regular sensor checks during maintenance
Sensor Issue
• Do not ignore the Check Engine Light
• Seek professional diagnosis if unsure
• Regular maintenance can prevent sensor issues
Sensor-related repairs may be covered under powertrain warranty if the vehicle is within the warranty period.
The P01E6 code is less common than other ECT sensor codes, often associated with specific models or manufacturing batches.
Moderate – While the vehicle may still be operable, ignoring the issue can lead to poor performance and increased emissions.
Driving with an unresolved sensor issue can lead to non-compliance with emission standards and potential engine damage.
• Engine at normal operating temperature
• Stable electrical system voltage
The Engine Coolant Temperature Sensor 3 is typically located near the thermostat housing or on the engine block.
Q: Can I drive my car with a P01E6 code?
A: It's possible, but not recommended. Driving with this code can lead to engine performance issues.
Q: How do I clear the P01E6 code?
A: After repairing the issue, use an OBD-II scanner to clear the code from the ECM.

Fitment Required · Vehicle-fitment part
Relevant when the fault points toward ignition-coil performance or cylinder-specific ignition issues.
Some ignition faults involve coil performance or cylinder-specific coil problems.
Match the coil to your engine and confirm the failed component before ordering.

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.
View options on AmazonThese parts may be related to this fault category, but a code by itself does not confirm exact fitment or guarantee that replacing a part will solve the problem.
