It monitors cylinder head temperature and sends that information to the ECU so ignition timing, air-fuel ratio, and protection strategies can be managed correctly.\u003c\/p\u003e\u003cp\u003eCompatible With Ski-Doo and Polaris models across a wide range of snowmobile and off-road applications, this sensor is built for direct OE-style replacement. Part number 933-5005 is engineered to match factory resistance values, thread dimensions, and response timing.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOE replacement cylinder head temperature sensor for precise engine temperature monitoring\u003c\/li\u003e\n\u003cli\u003eMeasures actual cylinder head metal temperature, not coolant temperature\u003c\/li\u003e\n\u003cli\u003eMatches OE resistance values, thread dimensions, and response timing\u003c\/li\u003e\n\u003cli\u003eBuilt with high-temperature, oil-resistant, and vibration-resistant materials\u003c\/li\u003e\n\u003cli\u003eDirect-fit design for factory harness connection without modification\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed Description\u003c\/h2\u003e\u003cp\u003eWalker 933-5005 is designed for engines that depend on accurate cylinder head temperature input to maintain proper combustion control. By reporting the temperature of the head itself, the sensor gives the ECU a more accurate thermal picture than a standard coolant temperature sensor. That information supports ignition timing control, air-fuel management, and fail-safe operation under demanding conditions. This part number 933-5005 is a practical OE-style replacement for Ski-Doo and Polaris machines where factory-level sensor accuracy matters.\u003c\/p\u003e\u003cp\u003eCommon symptoms of a failing sensor include hard starting, detonation, unstable idle, and fault codes tied to overheating or misfires. Walker 933-5005 restores the temperature signal the ECU expects, helping the system respond correctly during normal operation and high-load use.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHard starting caused by incorrect temperature input\u003c\/li\u003e\n\u003cli\u003eDetonation from inaccurate thermal reporting\u003c\/li\u003e\n\u003cli\u003eErratic idle related to sensor signal problems\u003c\/li\u003e\n\u003cli\u003eOverheating or misfire fault codes\u003c\/li\u003e\n\u003cli\u003ePoor combustion control under severe operating conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eInstall in the original sensor mounting location, typically in the cylinder head or water jacket, and connect to the factory harness. Verify thread engagement and connector fit before final assembly. For best results, compare the removed sensor’s connector style and mounting details with part number 933-5005 before installation.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eWalker builds this sensor to OE replacement standards using materials selected for heat, oil, and vibration resistance.
