Walker Products 933-5005 Engine Cylinder Head Temperature Sensor, Compatible with Select Polaris, Ski-Doo 2004-2023

The Walker Products 933-5005 Engine Cylinder Head Temperature Sensor is an OE Replacement component that monitors the temperature of the cylinder head and relays critical data to the engine control unit (ECU). Unlike standard coolant temperature sensors, these units measure the actual metal temperature of the engine head—providing a more accurate thermal profile for modern engine management strategies. This data allows the ECU to optimize ignition timing, air-fuel ratios, and activate fail-safes under extreme operating conditions. Common signs of a failed CHT sensor include hard starting, detonation, erratic idle, or triggering of fault codes related to overheating or misfires. They are engineered to match OE resistance values, thread dimensions, and response timing. Each unit is built using high-temperature, oil- and vibration-resistant materials for long-term durability in severe engine environments. Designed for exact OE fit, they install into the original mounting location—typically in the cylinder head or water jacket—and connect to the factory harness without modification. Whether resolving fault codes, correcting performance issues, or performing preventative maintenance, Walker Cylinder Head Temperature Sensors help restore precise temperature monitoring, protect engine components, and ensure proper combustion control under all driving conditions.
