Throttle Actuator Control System - Forced Engine Shutdown
This code means that the car's computer turned off the engine because there was a problem with the part that controls how much air goes into the engine.
The engine control module (ECM) has detected an issue with the throttle actuator control system and has shut down the engine to prevent damage.
The P2105 code is triggered when the ECM detects a malfunction in the throttle actuator control system, causing it to initiate a forced engine shutdown to prevent potential damage or unsafe driving conditions. The throttle actuator controls the opening and closing of the throttle plate, which regulates air flow into the engine.
• Check for other related codes and address them first.
• Inspect the throttle actuator and wiring for damage or disconnections.
• Test the throttle position sensor for proper operation.
• Replace the throttle actuator if faulty.
• Repair or replace damaged wiring or connectors in the throttle control circuit.
• Replace the throttle position sensor if it's malfunctioning.
• OBD-II scanner
• Multimeter
• Basic hand tools

Engine Performance
• Do not drive the vehicle until the issue is resolved to prevent further damage.
• Consult with a professional mechanic for accurate diagnosis and repair.
Check with your vehicle manufacturer for specific warranty coverage related to engine control components.
The P2105 code has been commonly reported in vehicles with electronic throttle control systems, especially as these systems age.
High – This code indicates a forced engine shutdown, which can be dangerous if it occurs while driving.
Driving with a malfunctioning throttle control system can be unsafe. Address this issue promptly to ensure vehicle safety.
• Engine at operating temperature
• Vehicle in idle or low-speed conditions
The throttle actuator is located on the throttle body, which is typically found on the intake manifold of the engine.
Q: Can I drive with a P2105 code?
A: It's not recommended to drive with this code as it indicates a forced engine shutdown, which can be unsafe.
Q: What happens if I ignore a P2105 code?
A: Ignoring this code can lead to further engine damage and unsafe driving conditions due to unexpected engine shutdowns.
