This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer thinks the part that controls how much air goes into the engine is stuck and can't move properly.
The throttle valve controls the amount of air entering the engine. If it gets stuck, it can affect engine performance.
P162D indicates that the throttle valve position control system has detected that the throttle valve is stuck in a position and cannot move as required. This is specific to Bank 2, which refers to the side of the engine with the second cylinder head in a V-type engine.
• Check Engine Light is on
• Poor engine performance
• Reduced fuel efficiency
• Faulty throttle body
• Wiring issues in the throttle control circuit
• Throttle position sensor malfunction
Throttle Body: A part of the air intake system that controls the amount of air entering the engine.
Bank 2: The side of the engine opposite to Bank 1, typically the side with the second cylinder head in a V-type engine.
• Use an OBD-II scanner to confirm the code.
• Inspect the throttle body for physical obstructions.
• Check the wiring and connectors for damage or corrosion.
• Clean or replace the throttle body.
• Repair or replace damaged wiring or connectors.
• Replace the throttle position sensor if faulty.
• OBD-II scanner
• Multimeter
• Throttle body cleaner

Moderate – It should be addressed soon to avoid further engine performance issues.
Driving with a malfunctioning throttle can lead to unsafe driving conditions.
• Engine at operating temperature
• Vehicle in park or neutral
The throttle body is typically located between the air filter box and the intake manifold.
