2.
Probe(+) : Injector power circuit NO1.
Probe(-) : Injector signal circuit NO2.
a.
Specification: 20℃(68℉) : 13.8~15.2Ω
The purpose of measuring injector resistance is to find if the open circuit is in the component.
Measure resistance between power circuit and signal circuit.
Probe(+) : Injector power circuit NO1.
Probe(-) : Injector signal circuit NO2.
Specification: 20℃(68℉) : 13.8~15.2Ω
Does each resistance indicate continuity circuit?
YES
Temporarily install a known good injector and check for proper operation
If problem is corrected, replace injector
NO
Open circuit injector
Repair as necessary and go to "Verification of Vehicle Repair" procedure
The purpose of measuring injector resistance is to find if the open circuit is in the component.So,check the continuity between signal line and ground line.
