FL -274 FUEL SYSTEM ▶ Repair open in the circuit between CMPS connector terminal 2 and ECM connector terminal 50 and go to "Verification of Vehicle Repair". 3. Check short to ground in signal circuit 1) IG KEY "OFF", ENGINE "OFF". 2) Disconnect CMPS connector and ECM connector. 3) Check continuity between CMPS connector terminal 2 and chassis ground. Specification : Discontinuity ( Infinite Ω ) 4) Is the measured resistance within the specification? YES ▶ Go to "Component Inspection". NO ▶ Repair short to ground in signal circuit and go to "Verification of Vehicle Repair". GROUND CIRCUIT INSPECTION E109ED58 1. IG KEY "OFF", ENGINE "OFF". 2. Disconnect CMPS connector. 3. IG KEY "ON". 4. Check the voltage of CMPS connetor terminal 2. [ TEST "A" ] 5. Check the voltage between CMPS connetor terminal 2 and 3. [ TEST "B" ] Specification : [TEST "A"] Voltage - [TEST "B"] Voltage = below 200mV 6. Is the measured voltage within the specification? YES ▶ Go to "Component Inspection". 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 resistance and go to "Verification of Vehicle Repair". COMPONENT INSPECTION E3BD4005 1. Cam shaft detecting teeth inspection 1) IG KEY "OFF", ENGINE "OFF". 2) Disconnect CMPS connector. |
