NTK EF0008 sensor for the 1999-2013 GMC Sierra 1500 4.3L and other vehicles is an air charge and engine coolant temperature sensor that sends the ECM an analog temperature signal for proper air/fuel ratio and cooling fan operation.
- Thermal conductive grease inside the brass housing speeds up sensor response time.
- Probe length matches OE.
- Thermistor placement in the housing matches OE for proper output.
- Designed to meet or exceed OE specifications in form, fit and function.
- Tested under thermal shock, vibration and OBD verification.
A check engine light, an erratic or dead temperature gauge, a cooling fan that runs erratically or not at all, or engine overheating can point to a failing sensor. These signs alone do not prove the sensor is at fault; a damaged connector is one other common source.
It is listed across a wide range of Chevrolet, GMC and Buick models, including the 1999-2011 Chevrolet Silverado 1500 4.3L and the 1995-2000 Chevrolet Tahoe 5.7L, and each needs one sensor. Open the "Vehicles it fits" section and look up your exact model and engine.
