Question
How to diagnose injector leakage via diagnostic waveform analysis?
Answer
It identifies fuel leakage through injector pintle seals.
Explain
Injector leakage causes rich air-fuel mixture. CHEPQ oscilloscopes analyze injector closing waveform, detect extended current decay or voltage anomalies, and verify pintle seal integrity. This identifies leaking injectors, preventing poor fuel economy and emissions spikes.
