Eclipse L4-2.4L SOHC (2004)
Example 2
-
Cause of problem
Open circuit in the line between the idle air control motor and the ECM or PCM.
-
Wave pattern characteristics
Current is not supplied to the motor coil on the open circuit side. (Voltage does not drop to 0 volt.) Furthermore, the induced electromotive force
wave pattern at the normal side is slightly different from the normal wave pattern.
