This summary uses the existing diagnostic information shown in full below.
The car's part that helps control the engine's air is not working right and is stuck in a position where it shouldn't be.
The throttle deicing system is supposed to ensure that the throttle doesn't freeze in cold conditions. This code indicates that the system is stuck in the closed position.
The P164E code is triggered when the throttle deicing mechanism fails to operate correctly, causing the throttle to remain in a closed position. This can affect the air intake and engine performance.
• Engine performance issues
• Check Engine Light illuminated
• Reduced throttle response
• Faulty throttle deicing mechanism
• Electrical issue in the throttle control circuit
• Mechanical obstruction in the throttle body
Throttle Body: A part of the air intake system that controls the amount of air flowing into the engine.
Deicing: A process to prevent ice formation on vehicle components.
• Check for any diagnostic trouble codes (DTCs) stored in the vehicle's computer.
• Inspect the throttle body and deicing mechanism for any mechanical obstructions.
• Test the electrical connections and wiring for the throttle deicing system.
• Replace or repair the throttle deicing mechanism.
• Fix any wiring or electrical issues in the throttle control circuit.
• Clean or replace the throttle body if necessary.
• OBD-II scanner
• Multimeter
• Throttle body cleaner
$150 - $500
Moderate
• Vehicle 1
• Vehicle 2
• Vehicle 3
• Regular maintenance of the throttle body
• Ensure proper electrical connections
• Avoid driving in extremely cold conditions without proper vehicle preparation
Engine Performance
• Do not ignore the Check Engine Light.
• Seek professional diagnosis if unsure.
• Regularly inspect and maintain the throttle body and related components.
Check with your vehicle manufacturer for warranty coverage on throttle-related issues.
This code has been associated with vehicles operating in cold climates where throttle freezing is more common.
Moderate – It should be addressed soon to prevent further engine performance issues.
Driving with a malfunctioning throttle system can be unsafe and may lead to legal issues if emissions are affected.
• Vehicle parked in a cold environment
• Engine running at idle
The throttle body is typically located between the air filter and the intake manifold.
Q: Can I drive with a P164E code?
A: It's not recommended as it can affect engine performance and may lead to further issues.
Q: What causes the throttle to get stuck?
A: It can be due to mechanical obstructions, electrical issues, or a faulty deicing mechanism.

Fitment Required · Vehicle-fitment part
Relevant for airflow, fuel-trim, and intake-metering faults after confirming the sensor is actually at fault.
Airflow and fuel-trim codes can involve the mass air flow sensor after proper diagnosis.
Verify the sensor design and fitment for your exact vehicle.
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.
