This summary uses the existing diagnostic information shown in full below.
This code means that the car's computer is limiting the engine's power to make sure everything stays safe. It's like when you slow down on your bike because the road is bumpy.
The engine control module (ECM) has detected a condition that requires limiting the engine's torque output to prevent potential damage or unsafe operation.
P1605 is a diagnostic trouble code (DTC) that indicates the ECM has activated a safety protocol to limit the engine's torque. This is usually done to protect the engine or transmission from conditions that could cause damage, such as overheating or excessive load.
• Reduced engine power
• Check Engine Light on
• Poor acceleration

This code has been used by manufacturers to ensure engine safety by limiting power output in potentially hazardous conditions.
Moderate – While the vehicle can still be driven, it is recommended to address the issue promptly to avoid further complications.
Driving with limited engine power can affect vehicle performance and safety. It is advised to have the issue diagnosed and repaired by a qualified technician.
• Engine running
• Vehicle in motion
The engine control module is typically located in the engine bay or under the dashboard.
Q: Can I drive with a P1605 code?
A: Yes, but you may experience reduced engine power. It's best to get it checked soon.
Q: What causes the engine to limit torque?
A: The engine may limit torque to prevent damage from overheating or excessive load.
