Step-by-step diagnostic guide

ActionDescriptionTools Needed
Check for Other CodesUse an OBD-II scanner to check for any other related codes that could provide more context to the issue. This may help identify further problems with the hybrid system.OBD-II Scanner
Test the Temperature Sensor EUse a multimeter to test the resistance and functionality of temperature sensor “E”. Compare the readings with manufacturer specifications to ensure proper operation.Multimeter
Inspect Wiring and ConnectionsVisually inspect the wiring harness and connections leading to temperature sensor “E” for any signs of damage, corrosion, or poor connections that could cause an open or shorted circuit.Flashlight, Multimeter
Check for Circuit FaultsInvestigate the entire temperature sensor “E” circuit for any faults, including blown fuses, short circuits, or open circuits. Repair any damaged components.Flashlight, Multimeter
Test the Control ModuleTest the hybrid control module to ensure it is correctly receiving and processing data from temperature sensor “E”. If necessary, update or reprogram the module.Diagnostic Tool
Clear Codes and Test DriveAfter completing repairs, clear the fault codes and take the vehicle for a test drive to verify that the temperature sensor is working correctly.OBD-II Scanner, Vehicle Owner’s Manual
