FLA -478 FUEL SYSTEM 4) Measure the voltage between terminal 4 of TPS harness connector and chassis ground. Specification : Approx. 5V 5) Is the measured voltage within specification ? YES ▶ Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deteriora- NO ▶ Go to "Check short in power harness" as follows. 2. Check short in power harness 1) IG "OFF". 2) Disconnect TPS connector and PCM connector. 3) Measure the resistance between terminal 4 and 5 of TPS harness connector. 4) Measure the resistance between terminal 4 and 8 of TPS harness connector. 5) Measure the resistance between terminal 4 and 6 of TPS harness connector. 6) Measure the resistance between terminal 4 and 1 of TPS harness connector. Specification : Infinite 7) Is the measured resistance within specification ? YES ▶ Substitute with a known - good PCM and check for proper operation. NO ▶ Repair Short in power circuit and go to "Verification of Vehicle Repair" procedure. ※ Procedure of ETS Initialization VERIFICATION OF VEHICLE REPAIR E34B8F1E After a repair, it is essential to verify that the fault has been corrected. 1. Monitor and record the Freeze Frame Data for the Diagnostic Trouble Code(DTC) which has been diagnosed. 2. Using a Scantool, Clear the DTCs 3. Operate the vehicle within conditions noted in the freeze frame data or enable conditions 4. Monitor that all rediness test have been verified as " Complete " |
