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.
