Typically, a temperature sensor for a 2014 Chevy Silverado will cost between about $15 and $100, depending on the sensor type and whether you buy aftermarket or OEM. The engine coolant temperature (ECT) sensor is usually in the $20–$60 range aftermarket and $50–$100 if you buy GM Genuine parts; the intake air temperature (IAT) sensor tends to run around $15–$50 aftermarket and $40–$75 OEM. Prices vary by retailer and region.
The Silverado lineup for that year used several engines (4.3L V6, 5.3L V8, and 6.2L V8 in higher trims), but all rely on at least coolant temperature sensing and air intake temperature sensing. Replacements are a common DIY task, provided you buy the correct part number for your exact engine and VIN.
Common Temperature Sensors in the 2014 Silverado
Engine Coolant Temperature (ECT) Sensor
The ECT sensor monitors the engine's coolant temperature and helps the ECM adjust fuel delivery and ignition timing. It is usually located near the thermostat housing or cylinder head, depending on the engine variant. Replacement is typically straightforward and inexpensive, with prices similar to those listed above.
Intake Air Temperature (IAT) Sensor
The IAT sensor measures the temperature of air entering the engine so the ECU can optimize performance and emissions. It is commonly found in the intake manifold or MAF housing. Prices are in the lower end of the range for aftermarket parts.
Other temperature sensors
Some Silverado engines or transmissions may have additional temperature sensors (for transmission oil temp or other systems). These are less common for DIY replacement and usually cost more, particularly if OEM parts are used.
Price ranges you may see for these sensors in typical auto parts stores:
- Engine Coolant Temperature (ECT) Sensor: aftermarket roughly $10–$40; GM OEM often $50–$100.
- Intake Air Temperature (IAT) Sensor: aftermarket roughly $15–$50; GM OEM often $40–$75.
- Transmission temperature sensor (less common): aftermarket roughly $20–$60; OEM often $60–$120.
These prices are approximate and can vary by retailer, geographic location, and whether the sensor includes additional features (like a wiring harness or O-ring). Always verify the exact part number that matches your engine code and VIN before purchase.
Where to Buy and How to Verify Compatibility
To ensure you get the right sensor for your 2014 Silverado, check the engine code, VIN, and the part number listed by the retailer. Below are common sources where you can compare prices and options:
- GM dealer or GM Parts Direct: typically higher-end OEM pricing; expect roughly $40–$100 depending on sensor and engine.
- Auto parts chains (AutoZone, Advance Auto Parts, O'Reilly): broad aftermarket options; prices usually $10–$60 for ECT and $15–$50 for IAT.
- Online retailers and marketplaces (RockAuto, Amazon): often the best price and a wide range; make sure the part number matches your engine; prices commonly $5–$40 for aftermarket sensors.
Conclusion: select the correct sensor for your exact engine and VIN, and you may be able to replace it with simple hand tools in under an hour. If you're unsure which sensor your Silverado needs, consult a professional or reference the service manual for your specific trim and engine.
Summary
For a 2014 Chevy Silverado, the most common temperature sensors are the engine coolant temperature (ECT) sensor and the intake air temperature (IAT) sensor. Prices generally range from about $10 to $100 depending on aftermarket versus OEM and the specific sensor. Always confirm part numbers for your engine variant and consider purchasing from a retailer that offers easy returns if the part does not fit your VIN.
