How to Test DW10 Injectors
Leak-off test: Connect clear hoses to the injector return lines and compare fuel volumes at idle. The injector returning the most fuel is likely worn.
Correction values: Use a scan tool to read injector correction (IMA) values. Readings beyond ±3 mg/stroke indicate wear.
Resistance check: Measure resistance across the injector connector pins with a multimeter. Compare to manufacturer specs.
