Sensors

Sensors for semi trucks measure things like pressure, temperature, airflow, speed, and emissions so the engine, transmission, ABS, and warning systems can react correctly and protect your truck. We carry a wide range of truck sensors for everyday repairs and upgrades, including oil pressure and coolant level sensors, MAP and MAF airflow sensors, NOx sensors, ABS wheel speed sensors, proximity sensors, load/weight sensors, and TPMS parts for trucks, trailers, and RV setups when readings are off, a check light comes on, or performance and fuel economy drop. Fitment is important because the correct sensor can depend on your engine family and emissions system, the connector and wiring style, thread size, and the exact mounting location, so we help you match the right replacement by confirming your truck and component details and comparing specifications to avoid installation problems or incorrect signals. When you’re not sure which sensor you need, our team helps narrow it down so you get dependable data and fewer surprises on the road.
