How to solve the abnormal idle speed after cleaning the throttle valve?

With the automobile computer tester, enter the engine system, enter the active test, set the throttle again, and the idle speed returns to normal. The main reason is the loss of idle memory of the unplugged fuselage computer. In short, manual repair is very difficult and needs the help of a computer.

The learning setting method is divided into three steps: accelerator pedal releasing position learning, throttle closing position learning and idle air volume learning.

Throttle closed position learning operation, by monitoring the output signal of the throttle position sensor, learn the position when the throttle is completely closed. You must do this every time you disconnect the harness plug of the electronic throttle actuator or ECM.

Confirm that the accelerator pedal is completely released; Turn on the ignition key Position waiting for at least 2? Seconds; Ignition off? Wait at least 10? Seconds; Turn on the ignition key Position waiting for at least 2? Seconds; Ignition off? Wait at least 10? second

For automatic transmission models using CONSULT-II or X43 1 diagnostic instrument, drive the vehicle until the display value of oil temperature sensor is lower than 0.9V in data monitoring mode.
