Measure resistance between connector terminals.

Specification: 80.0 to 120.0 Ω

If specification is not obtained:

Replace No. 3 cylinder injector together with Needle Lift Sensor G80.
Check DTC memory and, if necessary, repair any malfunctions and then erase → Diagnostic Trouble Code (DTC) memory, checking and erasing .
Read readiness code → Readiness code, displaying .

If DTC memory has been erased, the readiness code must be generated again → Readiness code, setting .

If specification is obtained:
