To help plan a purchase, here are typical ranges you might see at major auto parts retailers and from OEM/dealership channels. These figures are representative and can vary by location and stock.
- Auto parts stores (aftermarket): ECT $10–$25; AAT $15–$40; IAT $8–$25; Transmission temp sensor $25–$60.
- Online retailers (variants of aftermarket parts): ECT $8–$25; AAT $12–$35; IAT $8–$22; Transmission temp sensor $20–$50.
- OEM/GM parts (ACDelco or dealership-sourced): ECT $25–$60; AAT $30–$60; IAT $25–$50; Transmission temp sensor $40–$90.

When shopping, verify the exact part number for your Tahoe’s engine and year, as pricing can vary by part number and supplier. If you’re on a budget, aftermarket sensors are typically the most economical choice and are generally compatible with the vehicle’s systems when matched to the correct part number.
Choosing the right part and installation tips
To ensure compatibility and reliability, confirm the sensor’s part number and cross-reference it with your vehicle’s VIN or service manual. Consider these tips when purchasing or replacing a sensor:
- Match the exact sensor type (ECT, AAT, IAT, or transmission temperature) to avoid incorrect readings.
- Weigh OEM versus aftermarket options based on warranty preferences and vehicle age; OEM parts often carry longer warranties but may cost more.
- Factor in potential coolant replacement or re-bleeding if you replace an engine coolant temperature sensor or other coolant-related components.
- If you’re not confident performing the replacement, consider professional installation to ensure proper sensor seating and electrical connections.
Replacing a faulty temperature sensor can prevent drivability issues, illuminate check engine lights, and improve sensor-based performance parameters. Always clear any fault codes after replacement to verify a successful repair.
Summary
For a 2015 Tahoe, parts pricing for temperature sensors generally ranges from about $8 to $120 depending on sensor type and whether you choose aftermarket or OEM parts. Engine coolant temperature sensors tend to be the most affordable option, while transmission temperature sensors and OEM dealership parts can be pricier. Labor costs are extra if you have a shop perform the replacement. Always confirm the exact part number for your vehicle and compare prices across reputable retailers to get the best deal.
