The purpose of the Inspection is to analyze the cause of the poor power/acceleration by checking injector resistance and waveform.
IG "OFF"
Measure resistance between the terminal "1" and "2" each injector.
Specification : 13.8~15.2Ω at 20℃(68℉)
It is essential to verify that the resistance measured at the same temperature is similar to each other.
Are Injector resistances within specification?
YES
Go to "Injector waveform Inspection" procedure as below.
NO
Replace the injector
Engine "ON" and warm up the engine until cooling fan is operated.
Measure injector waveform at idle.
Is normal injector waveform displayed?
YES
Injector is OK
NO
Replace the injector after checking injector wiring harness and ECM.
