Technical Data - Coolant Temp Sensor Resistance Values
Use the specification table below to check the Coolant Temp Sensor. The values in the table show the approximate resistance values for the temperatures given. The actual resistance can vary some from the table. Typically, if the sensor is faulty the resistance value will be noticeably different from the specification in the table.

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.
