High Idle Speed After Replacing Idle Speed Motor and Solutions

[VanZoe]

The solutions for high idle speed after replacing the idle speed motor are as follows: Method 1: Air leakage in the intake system caused during cleaning leads to high idle speed. If this occurs again, ask the technician to confirm there is no air leakage in the intake pipe. Another issue could be poor connection of the idle speed motor, which may cause stalling or high idle speed. Method 2: This could be due to unstable idle speed control or excessive carbon deposits affecting the idle speed control system of the electronically controlled engine. Method 3: The ECU controls the engine to maintain optimal working conditions based on input signals from various sensors. When this fault occurs, primarily check if the input signals from each sensor to the ECU are normal, and then inspect the working condition of the actuators.
