This summary uses the existing diagnostic information shown in full below.
The car's computer thinks the temperature reading from a part that controls airflow to the engine doesn't make sense.
The active grille air shutter system helps manage engine temperature and aerodynamics. This code indicates a problem with the temperature reading from the shutter module.
The P3065 code is triggered when the Engine Control Module (ECM) detects an implausible temperature reading from the Active Grille Air Shutter Module 'A'. This could be due to a sensor malfunction or wiring issue affecting the temperature signal.
• Check Engine Light illuminated
• Reduced fuel efficiency
• Possible overheating in extreme conditions
• Faulty temperature sensor in the grille shutter module
• Wiring issues such as shorts or open circuits
• Defective active grille air shutter module
ECM: Engine Control Module

• Use an OBD-II scanner to confirm the P3065 code.
• Inspect the wiring and connectors of the active grille air shutter module.
• Test the temperature sensor for proper operation.
• Replace the faulty temperature sensor.
• Repair or replace damaged wiring or connectors.
• Replace the active grille air shutter module if necessary.
• OBD-II scanner

Moderate
• Chevrolet Silverado
• Ford F-150
• Toyota Camry
• Regular maintenance checks
• Ensure wiring and connectors are secure
• Keep the grille area clean and free of debris
Sensor Issue
• Have the vehicle inspected by a professional if the Check Engine Light is on.
• Avoid ignoring the issue as it may affect fuel efficiency.
Check with the vehicle manufacturer for warranty coverage on emissions-related components.
This code has been more prevalent in vehicles with active grille systems introduced in the past decade.
Moderate – Should be addressed to maintain optimal engine performance and fuel efficiency.
Driving with a malfunctioning active grille system may lead to increased emissions and reduced fuel efficiency.
• Engine at operating temperature
• Vehicle in a stationary position
The active grille air shutter is located at the front of the vehicle, typically behind the front bumper.
Q: What happens if I ignore the P3065 code?
A: Ignoring the code can lead to reduced fuel efficiency and potential engine overheating.
Q: Can I drive with a P3065 code?
A: While the vehicle may still be drivable, it is recommended to fix the issue to avoid further complications.
