1. Turn the ignition off.
2. Connect the PCM C1 and C2 harness connectors.
3. Connect a jumper wire between the (K914) Sensor Ground circuit and the (G24) EOT Signal circuit in the Engine Oil Temperature Sensor harness connector.
4. Turn the ignition on.
5. With the scan tool, read the Engine Oil Temperature Sensor signal voltage.
  Is the voltage below 1.0 volt with the jumper wire in place?
  
  Yes
  - Replace the Engine Oil Temperature Sensor in accordance with the Service Information. Refer to SENSOR, OIL TEMPERATURE, REMOVAL .
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to PCM VERIFICATION TEST .
  No
  - Go To 9.
POWERTRAIN CONTROL MODULE (PCM)
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Engine Oil Temperature Sensor and the Powertrain Control Module (PCM).
2. Look for any chafed, pierced, pinched, or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals.
4. Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
