Why is there no difference in idle speed?
Why is there no difference in idle speed?
No difference between the two idle speed means the Idle Control Motor is not working. This method for idle air control valve symptoms confirm if there is a problem with the idle control motor, not the problem itself. A poorly idling engine may run too fast or too slow or stall.
Why is my idle control not working on my car?
If the idle has not changed at all, it’s likely because your idle control motor has not been functioning. If the idle control motor was working, disconnecting it should have created a difference in the engine’s idle. This test confirms there’s an issue with the idle control motor, but not what the issue may be.
Can a bad idle control valve cause stalling?
3. Engine stalling The idle control valve, also commonly referred to as the idle air control valve, is an engine management component that is found in one form or another on the majority of road going vehicles.
How can I increase idle speed in a Chrysler?
If the resistance is outside that range, the idle control motor needs to be replaced. Use a bidirectional scan tool to increase idle speed in a Chrysler. Connect a bidirectional scan tool to the same OBD port you would plug a code scanner into. Use the command in the scan tool to increase the engine’s idle.
When do I switch to idle speed control?
The control mode selection logic switches to idle speed control when the throttle angle reaches its zero (completely closed) position as detected by a switch on the throttle that is closed and engine RPM falls below a minimum value. This condition often occurs when the vehicle is stationary.

Why is my idle control system not working?
The most common problem we experience with the idle control system is that the TPS is not working, either because it has failed and/or the throttle body is worn out. In either case, the TPS will not close/open when it should, so the idle control system doesn’t get the information it needs.
