Where do I find idle effort on my ECU?
The RPM field shows the current RPM, the target RPM and the idle effort (which could be duty cycle, number of steps or electronic throttle authority). You can also add it to the monitor window and it also appears in various idle setup pages. Now, let’s look at the cranking condition.
What should the idle speed be on a port injected engine?
This is best done with an engine starting from cold. Firstly, set the target idle speed against the coolant temperature; most port injected engines want to run higher RPM when they are cold to combat the fuel falling out of suspension at low temperatures.
Why does my car idle at a higher RPM than normal?
Updated January 19, 2019. If your car seems to be revved up to a higher-than-normal RPM while idling, it’s not necessarily a problem. If this problem happens while the engine is cold, it may be part of the engine’s design.
When does open loop idle control turn on?
Normally this goes high to 12V when the headlights are on, but is shorted to ground when they are off. Again this should be connected to a digital input, and then the input should be selected as an electrical load, for example electrical load 1.
How to perform Ford idle relearn you MPT performance?
Turn the air conditioning on and allow the engine to idle for at least one minute. Release the parking brake. With your foot on the brake pedal and the A/C still on, put the vehicle in “D” (Drive) and allow the engine to idle for at least one minute. Drive the vehicle to complete the relearning process.
What causes the idle speed to go up or down?
The idle air control valve is programmed to regulate and maintain the engine idle speed at a constant rate. If the valve fails or has any issues it can cause the idle speed to be thrown off. This may result in an unusually high or low idle speed, or in some cases a surging idle speed that repeatedly climbs and falls. 2. Check Engine Light comes on
When does idle come back to normal on a Harley Davidson?
Just seems to happen when I’ve been running at a fairly wide open throttle maintaining higher speeds for a while (fwy) or longer stints (catching all green lights) on the streets at a speed of about 45 or more. It always seems to come back to a normal idle after getting back into first gear when stopped, or when I start going again in 1st.
When do I need to do an idle relearn?
When this happens it is sometimes necessary to perform an idle relearn to once again teach the car how to idle correctly. With vehicle at a complete stop, set the parking brake.
