This summary uses the existing diagnostic information shown in full below.
This means that the car's computer thinks there's a problem with the wires or parts that control one of the fans that help keep the engine cool.
The P0693 code indicates that the vehicle's computer has detected a low voltage condition in the circuit that controls the second cooling fan.
The P0693 code is triggered when the Engine Control Module (ECM) detects a low voltage or open circuit condition in the control circuit for the second cooling fan. This could be due to a faulty fan motor, wiring issues, or a problem with the fan control relay.
• Engine overheating
• Cooling fan not operating
• Check Engine Light illuminated
• Faulty cooling fan motor
• Damaged wiring or connectors
• Defective fan control relay
ECM: Engine Control Module
Relay: An electrically operated switch
• Inspect the cooling fan motor and wiring for damage.
• Check the fan control relay for proper operation.
• Test the voltage and ground at the fan motor connector.
• Replace the cooling fan motor if faulty.
• Repair or replace damaged wiring or connectors.
• Replace the fan control relay if defective.

Moderate
• Chevrolet Silverado
• Ford F-150
• Toyota Camry
• Regularly inspect fan wiring for damage.
• Ensure cooling fans are clean and unobstructed.
• Perform routine maintenance checks on the cooling system.
Electrical Circuit Issue
• Do not ignore the Check Engine Light.
• Monitor engine temperature closely.
• Seek professional diagnosis if unsure.
Cooling system components may be covered under the vehicle's powertrain warranty. Check with the manufacturer.
The P0693 code has been a common issue in vehicles with electric cooling fans, especially as vehicles age and wiring becomes more susceptible to wear.
Moderate – While the vehicle may still be drivable, ignoring this issue can lead to engine overheating, which can cause severe engine damage.
Driving with an overheating engine can cause severe damage and may not be covered under warranty if ignored.
• Engine running at normal operating temperature
• Cooling fan operation cycle
The cooling fan and its control circuit are typically located at the front of the engine bay, behind the radiator.
Q: Can I drive my car with the P0693 code?
A: It's not recommended to drive for long periods with this code as it can lead to engine overheating.
Q: How do I know if my cooling fan is not working?
A: You may notice the engine temperature rising or hear no fan noise when the engine is hot.
