Lancer L4-2.4L SOHC (2005)
Standard Wave Pattern
Wave Pattern Observation Points
Point: The power transistor control signal (ignition timing) is advanced when the engine speed is increased.
Examples of Abnormal Wave Patterns
Example 1 (Wave pattern during engine cranking)
-
Cause of problem
Open-circuit in ignition primary circuit
-
Wave pattern characteristics
Voltage value is too low.
