Sensors

Sensors for semi-trucks measure key conditions and send signals to the engine and safety systems so your truck can run efficiently and warn you early when something is wrong. Our sensor options cover common needs like oil pressure sensors, coolant level and oil/coolant sensors, thermostats, NOx sensors, ABS sensors, TPMS tire pressure sensors, proximity sensors, and airflow sensors such as MAF and MAP sensors, which are often replaced when a warning light comes on, a gauge reading is incorrect, or performance and fuel economy drop. Fitment matters because trucks can use different sensor types by engine family, emissions setup, connector style, thread size, and location on the vehicle, so we help you match the right part by verifying your truck details and comparing specifications to avoid wiring or calibration issues. If you’re unsure which sensor you need, our team can help confirm the correct replacement so you get dependable readings and fewer surprises on the road.
