Inspection [12/2024 - ]: Procedure
- INSPECT NO. 2 ENGINE COOLANT TEMPERATURE SENSOR (except Mexico Models)
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition Result 1 (E2) - 2 (THTW) 20°C (68°F) 2.32 to 2.59 kΩ kΩ 1 (E2) - 2 (THTW) 80°C (176°F) 0.310 to 0.326 kΩ kΩ NOTE:If checking the No. 2 engine coolant temperature sensor in water, be careful not to allow water to contact the terminals. After checking, wipe the water off the No. 2 engine coolant temperature sensor.
If the result is not as specified, replace the No. 2 engine coolant temperature sensor.

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.
