ActionDescriptionTools Needed
Check for Other CodesUse an OBD-II scanner to check for additional codes related to the sensors or circuit that may provide more information.OBD-II Scanner
Check Sensor CorrelationUse a diagnostic tool to compare the readings from both Hybrid Battery Temperature Sensors ‘F’ and ‘G’ to see if they align with each other and with the manufacturer’s specifications.Diagnostic Tool, Multimeter
Test the Temperature SensorsTest both sensors independently to ensure they are providing accurate temperature readings and are functioning properly.Multimeter, Temperature Sensor Tester
Inspect the Sensor CircuitVisually inspect the wiring and circuit for both sensors for any signs of damage, wear, or corrosion that could cause discrepancies in their readings.Flashlight, Multimeter
Check Wiring and ConnectionsInspect the wiring and connectors between the sensors and the control unit for any loose or corroded connections that could lead to inconsistent readings.Flashlight, Multimeter
Test Circuit ContinuityPerform a continuity test on the circuit for both sensors to ensure there are no breaks or shorts that could be affecting sensor performance.Multimeter
Clear the Code and Test DriveAfter repairs or adjustments, clear the P0C86 code using an OBD-II scanner and take the vehicle for a test drive to verify that the issue is resolved.OBD-II Scanner, Vehicle Owner’s Manual
Recheck for CodesAfter the test drive, re-scan the vehicle to ensure the P0C86 code has not returned.OBD-II Scanner
