Component Testing
WARNING: This page is about a different car, the 2018 Chevrolet Suburban 3500 HD. However, it is still accessible from the selected car via links, so may be relevant.
- Ignition/Vehicle - Off
- Disconnect the electrical connector: B34 Engine Coolant Temperature Sensor
- Test for 42 to 78, 834 Ω between the test points: Signal terminal 2/B & Low Reference terminal 1/A
- If not between 42 to 78, 834 Ω
Replace the component: B34 Engine Coolant Temperature Sensor
- Go to next step: If between 42 to 78, 834 Ω
- If not between 42 to 78, 834 Ω
- Verify the value is within the range listed in the table: Temperature Versus Resistance - Engine Coolant Temperature Sensor
- If not in the specified range
Replace the component: B34 Engine Coolant Temperature Sensor
- Go to next step: If in the specified range
- If not in the specified range
- Test for infinite resistance between the test points: Each terminal of the component & The component's housing
- If less than infinite resistance
Replace the component: B34 Engine Coolant Temperature Sensor
- Go to next step: If infinite resistance
- If less than infinite resistance
- All OK.
