(1) Check sensor voltage using New Generation Star (49 T088 0A0) scan tool connected to Data Link Connector (DLC) 2. DLC is located under left side of instrument panel, right of steering column.
(2) Measure resistance between cylinder head temperature sensor terminals.
(3) At this temperature, there is a voltage overlap zone where it is possible to have either a cold end (low voltage) or hot end (high voltage) reading at the same temperature. Either voltage specification listed is correct.

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.
