DIESEL CONTROL SYSTEM FLA -495 3) Check continuity between Lambda sensor connector terminal 6 and ECM connector terminal 65. Specification : Continuity (below 1.0Ω ) 4) Is the measured resistance within the specification? YES ▶ Repair short to ground in Lambda sensor pump circuit and go to "Verification of Vehicle Repair". NO ▶ Repair open in Lambda sensor pump circuit and go to "Verification of Vehicle Repair". GROUND CIRCUIT INSPECTION EFBBCBA8 1. Check voltage in sensor ground circuit 1) IG KEY "OFF", ENGINE "OFF". 2) Disconnect Lambda sensor connector. 3) IG KEY "ON". 4) Measure the voltage of OLambda sensor connector terminal 3. Specification : 2.3V~2.7V 5) Is the measured voltage within the specification? YES ▶ Go to"Component Inspection". NO ▶ No voltage detected in Lambda sensor ground circuit : Go to "2. Check open in sensor ground circuit" as 2. Check open in sensor ground circuit 1) IG KEY "OFF", ENGINE "OFF". 2) Disconnect Lambda sensor connector and ECM connector. 3) Check continuity between Lambda sensor connector terminal 3 and ECM connector terminal 86. Specification : Continuity (below 1.0Ω ) 4) Is the measured resistance within the specification? YES ▶ Repair short to ground in Lambda sensor ground circuit and go to "Verification of Vehicle Repair". |
