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:
Exact OE Fit: Designed for 100% compatibility with factory threads, connectors, and mounting positions—no modification required.
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.
OE Replacement Design: Matches original resistance curve, response time, and temperature range for system accuracy and reliability.
Monitors Cylinder Head Temperature: Sends critical thermal data to the ECU to optimize ignition timing, fuel delivery, and engine protection.

Overall rating: 4.9 / 5 from 594 reviews.
I love PartsPioneer. The rear-wheel Positive Plus pads and Genius rotors fit perfectly on my 2019 Subaru Forester. Excellent quality at a fair price. Highly recommended.
Thanks for catching an error in my order and righting it for me, complete with email to say so! This … is what customer service head and shoulders above, looks like !! Well done all !!
Service was great, appreciated the phone call to confirm the vehicle. Parts arrived quick. OEM fit. Will be ordering brakes as you can see by the picture. Very impressed.
I have bought this rotor on part pioneer for my Q3 and installed and used for over a week, they are amazing no squeaks no noises brakes have improved 110%. This rotors are the best so far I’ve always bought rotors and used in all three of my cars and so far these ones are the best that I have ever bought.
Thanks
