10. CHECK INJECTOR RESISTANCE • Check resistance as table shown. • Check the fuel injector resistance as shown in the following: INJECTOR NO. INJECTOR TERMINAL RESISTANCE (APPROXIMATELY) ⍀ (20°C) 1 1 & 2 11 - 16 2 1 & 2 3 1 & 2 4 1 & 2 • Connect ECM connector. • Connect injector connector. • Check the fuel injector voltage as shown in the following: TERMINAL NO. ITEM CONDITION DATA (AVERAGE DC VOLTAGE) 6 Injector 2 • Engine is running • Warm-up condition • Idle • Accelerate suddenly Voltage: 11 - 14 V 7 Injector 3 27 Injector 1 47 Injector 4 Is the check result normal? Yes >> Go to the next step. No >> Replace injector. 11. CHECK DTC • With the X-431 scan tool, read ECM DTCs. • See ⬙DTC Confirmation Procedure⬙. Is DTC P0261, P0264, P0267 or P0270 still present?
