This summary uses the existing diagnostic information shown in full below.
This code means there's a problem with the car's front grille shutters, which help control the engine temperature. They aren't working right all the time.
The active grille air shutter system helps improve fuel efficiency and engine performance by controlling airflow through the radiator. This code indicates an intermittent issue with the position sensor circuit of the grille shutters.
The P059E code is triggered when the Engine Control Module (ECM) detects an intermittent fault in the circuit of the position sensor for the active grille air shutter. This sensor provides feedback on the position of the shutters to ensure they are opening and closing as needed.
• Check Engine Light is on
• Reduced fuel efficiency
• Engine overheating in some conditions
• Faulty grille shutter position sensor
• Wiring issues such as loose connections or damaged wires
• Faulty active grille air shutter actuator

• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for the grille shutter system.
• Test the position sensor for proper operation.
• Repair or replace damaged wiring or connectors.
• Replace the grille shutter position sensor.
• Replace the active grille air shutter actuator if necessary.
• OBD-II scanner

Moderate
• Chevrolet Silverado
• Ford F-150
• GMC Sierra
• Regularly inspect the grille shutter system for debris.
• Ensure wiring and connectors are secure and undamaged.
• Perform routine maintenance checks.
Sensor Issue
• Avoid driving in extreme conditions until repaired.
• Monitor engine temperature closely.
• Consult a mechanic if unsure about DIY repairs.
Repairs may be covered under manufacturer warranty if the vehicle is still within the warranty period.
This code has become more common with the introduction of active grille shutter systems in modern vehicles to improve aerodynamics and fuel efficiency.
Moderate – It should be addressed soon to prevent potential engine overheating.
Driving with a malfunctioning grille shutter system may lead to engine overheating, which can be dangerous.
• Vehicle at operating temperature
• Grille shutters in motion
The active grille air shutter is located at the front of the vehicle, behind the grille.
Q: Can I drive with a P059E code?
A: It's possible to drive for a short time, but it's best to fix it soon to avoid engine issues.
Q: Will this code affect my car's performance?
A: Yes, it can reduce fuel efficiency and potentially cause overheating.
