ON-BOARD DIAGNOSTIC K–69 K End Of Sie 3 VERIFY CURRENT INPUT SIGNAL STATUS • Turn ignition key to OFF. • Start engine. • Measure frequency of input/turbine speed sensor using a oscilloscope. • Are frequency of input/turbine speed sensor readings within specifications? Yes Go to intermittent concern troubleshooting procedure. (See No Go to next step. 4 INSPECT INPUT/TURBINE SPEED SENSOR • Turn ignition key to OFF. • Disconnect input/turbine speed sensor connector. • Check for poor connection (damaged/pulled- out terminals, corrosion, etc.). • Is connection okay? Yes Go to next step. No Repair or replace connector and/or terminals, then go to 5 INSPECT INPUT/TURBINE SPEED SENSOR • Measure resistance between input/turbine speed sensor terminals (part-side). • Is resistance within 250—600 ohms between input/turbine speed sensor terminals (part- K–23 INPUT/TURBINE SPEED SENSOR Yes Go to next step. No Replace input/turbine speed sensor, then go to Step 10. K–24 INPUT/TURBINE SPEED SENSOR REMOVAL/ 6 INSPECT INPUT/TURBINE SPEED SENSOR • Remove input/turbine speed sensor. • Is there iron powder stuck on input/turbine K–24 INPUT/TURBINE SPEED SENSOR .) Yes Clean input/turbine speed sensor, then go to Step 10. No Go to next step. 7 INSPECT PCM CONNECTOR FOR POOR • Disconnect PCM connector. • Check for poor connection (damaged/pulled- out terminals, corrosion, etc.). • Is connection okay? Yes Go to next step. No Repair or replace connector and/or terminals, then go to 8 INSPECT INPUT/TURBINE SPEED SENSOR • Inspect input/turbine speed sensor terminals (harness-side) and PCM terminals (harness- • Is there continuity? Yes Go to next step. No Repair or replace harness, then go to Step 10. 9 INSPECT INPUT/TURBINE SPEED SENSOR • Inspect input/turbine speed sensor terminal (harness-side) and body ground. • Is there continuity? Yes Repair or replace harness, then go to next step. No Go to next step. 10 VERIFY TROUBLESHOOTING OF DTC P0715 • Make sure to reconnect all disconnected connectors. • Clear DTC from memory using WDS or equivalent. • Drive vehicle with vehicle speed 40 km/h {25 mph} or above for 0.7 second or more. • Is same DTC present? Yes Replace PCM, then go to next step. (See No Go to next step. 11 VERIFY AFTER REPAIR PROCEDURE • Perform “After Repair Procedure”. • Are any DTCs present? Yes Go to applicable DTC inspection. No Troubleshooting completed. STEP INSPECTION ACTION |
