Question

in all vehicles, you can disconnect the electrical connector on the idle speed control system to prevent the pcm from changing the idle speed. select one: true false

Explanation:

Not all vehicles have the same idle speed control system design. Some vehicles may have alternative methods or safeguards that prevent simply disconnecting the electrical connector from effectively stopping the PCM (Powertrain Control Module) from adjusting idle speed. There could be redundancy in the system, or the PCM might have default fallback mechanisms that still influence idle speed even if one connector is disconnected.

Answer:

False
