How do I relearn throttle body Mitsubishi?
The following works for most endeavors, evos and outlanders:
- Perform this when engine is cold.
- disconnect negative battery terminal for about a minute.
- Reconnect negative battery terminals.
- Insert key turn to check mode (dont start it) leave it like that for a minute or two.
- Turn key to off mode and turn car on.
How long does it take for GM throttle body to relearn?
If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle. It will eventually learn it on its own, but it may take over a week of driving, during which time you will experience high and low idle speeds and possibly rough idle. 1) Start the engine and let it idle in park for 3 minutes.
How to do throttle body cleaning and idle relearn?
1. Start and idle the engine in PARK for 3 minutes. 2. With a scan tool, monitor desired and actual RPM. 3. The ECM will start to learn the new idle cells and Desired RPM should start to decrease. 4. Ignition OFF for 60 seconds.
What happens when you replace the throttle body?
If you replace the throttle body, the PCM won’t know and will continue to use the adaptive settings as if the carbon buildup is still in place. If you don’t do a relearn procedure, the PCM will “hunt” for a new baseline idle.
How does the ECM learn the new throttle position?
Perform the Throttle Learn Procedure. Refer to Throttle Learn. The engine control module (ECM) learns the idle position of the throttle plate to ensure the cor- rect idle. Anytime the throttle body is cleaned or replaced, the ECM must learn the new throttle position.
