Walker Products Engine Cylinder Head Temperature Sensors are OE Replacement components that monitor the temperature of the cylinder head and relay 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. Walker CHT Sensors 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.
Characteristics include:
Built for Thermal Durability: Constructed from heat-resistant materials to perform reliably under constant exposure to extreme engine heat.
Supports Engine Safety & Efficiency: Helps prevent overheating, detonation, and drivability issues by enabling real-time thermal control.
Monitors Cylinder Head Temperature: Sends critical thermal data to the ECU to optimize ignition timing, fuel delivery, and engine protection.
OE Replacement Design: Matches original resistance curve, response time, and temperature range for system accuracy and reliability.
Exact OE Fit: Designed for 100% compatibility with factory threads, connectors, and mounting positions—no modification required.

This my second time buying from Partspionner.ca great parts quality parts fast shipping to your door no need to wait on parts counter for minutes save gas ;)
I had an excellent experience ordering from Parts Pioneer, my order was placed and shipped quickly and received. Excellent customer service, I will definitely use them again when needed and let many of my friends know about Part's Pioneer
The site was very easy to use. When I emailed with a question the response came quickly. I appreciated that you verified that the parts would fit my vehicle. I will use the site again.
La livraison se fait en un temps record, malheureusement il y a eu un erreur de pièce, par contre un service très professionnel, facile d'accès et dans ma langue natale..... Le retour est accepté sans frais. Tout les professionnels dans le domaines de la mécanique savent que des erreurs survient aléatoirement au niveaux pièces un jour ou l'autre, pas très agréable mais la ou ce joue la qualité du service est le service après vente et je peux confirmé la compétence de l'équipe Parts Pionner... Merci à l'équipe
Toujours en attente du ticket de retour mais j'ai confiance dans leurs bref délais...
