FL -518 FUEL SYSTEM ▶ Go to "3.Signal Circuit Inspection (APS 2)" as follows. NO ▶ Repair short in circuit and go to "Verification of Vehicle Repair". 3. Signal Circuit Inspection (APS 2) 1) IG KEY "OFF", ENGINE "OFF" 2) Disconnect APS connector and ECM connector. 3) IG KEY "ON" 4) Check continuity between APS connector terminal 3 and chassis ground. (check short to ground ) Specification : Check short to ground : Discontinuity ( Infinite Ω ) Check short to battery : 0.0V~0.1V 5) Is APS 2 signal circuit insulated normally? YES ▶ Go to "Ground Circuit Inspection". NO ▶ Repair short in circuit and go to "Verification of Vehicle Repair". GROUND CIRCUIT INSPECTION E1384424 1. Check ground circuit (APS1) 1) IG KEY "OFF", ENGINE "OFF" 2) Disconnect APS connector. 3) IG KEY "ON" 4) Measure the voltage of APS terminal 4. [ TEST "A" ] 5) Measure the voltage of APS terminal 4 and terminal 5. [ TEST "B" ] Specification : [TEST "A"] Voltage - [TEST "B"] Voltage = below 200mV 6) Is the measured voltage within the specification? YES ▶ Go to "2. Check ground circuit (APS2)". NO ▶ When "B" voltage is not detected : Repair open in ground circuit and go to "Verification of Vehicle Repair". ▶ When the voltage difference between "A" and "B" is above 200mV : Eliminate the causes of excessive resis- tance and go to "Verification of Vehicle Repair". |
