This summary uses the existing diagnostic information shown in full below.
This code means that something is wrong with the car's fan relay circuit, which is like a switch that helps keep the car cool. It's saying the switch has too much power going through it.
The P144E code indicates that the fan safety relay circuit is experiencing higher than normal voltage, which could be due to a fault in the relay or the wiring.
The P144E code is triggered when the Engine Control Module (ECM) detects a voltage level in the fan safety relay circuit that is higher than the expected range. This can be due to a short circuit, faulty relay, or issues with the wiring harness.
• Engine overheating
• Cooling fan not operating
• Check Engine Light illuminated
• Faulty fan relay
• Short circuit in the wiring
• Faulty ECM
Relay: An electrical switch that opens and closes under the control of another electrical circuit.
ECM: Engine Control Module, the computer that controls engine functions.
• Check for any blown fuses related to the fan circuit.
• Inspect the fan relay for signs of damage or corrosion.
• Test the wiring harness for continuity and shorts.
• Replace the faulty fan relay.
• Repair or replace damaged wiring.
• Reprogram or replace the ECM if necessary.
• Multimeter
• Relay tester
• OBD-II scanner

Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regularly inspect and maintain cooling system components.
• Ensure the fan relay and wiring are kept clean and dry.
• Perform routine diagnostic checks with an OBD-II scanner.
Electrical Circuit Issue
• Do not ignore the Check Engine Light; get the vehicle checked as soon as possible.
• Monitor the engine temperature gauge to prevent overheating.
• Seek professional help if unsure about the repair process.
Check with the vehicle manufacturer for warranty coverage on electrical components.
The P144E code has been associated with issues in vehicles with complex cooling systems, particularly in models with electric cooling fans.
High – This issue can lead to engine overheating if not addressed promptly.
Driving with an overheating engine can cause severe damage and is not safe. Address this issue immediately.
• Engine running at normal operating temperature.
• Cooling fan activation conditions met.
The fan relay is typically located in the engine compartment fuse box.
Q: Can I drive with the P144E code?
A: It is not recommended to drive with this code as it can lead to engine overheating.
Q: How can I reset the P144E code?
A: After repairs, the code can be cleared using an OBD-II scanner.
