Walker Products Engine Intake Manifold Temperature Sensors are precision-engineered OE Replacement components that measure the temperature of incoming air entering the engine’s intake system. This data is critical for the engine control unit (ECU) to calculate air density, optimize fuel injection, adjust ignition timing, and manage emissions output. Unlike external air temp sensors, these sensors operate inside the intake manifold or air tract—providing a more accurate measurement of actual combustion air temperature under load. Over time, intake manifold temperature sensors can degrade, causing incorrect temperature readings that result in rich/lean fuel trims, drivability issues, hesitation, or emissions faults. Walker sensors are manufactured to meet or exceed OE specifications for resistance curves, temperature range, and electrical response. Built from durable, heat- and oil-resistant materials, they are designed to endure thermal cycling and exposure to oil vapor, fuel mist, and engine heat. Each unit is engineered for an exact OE fit and installs directly into the factory manifold, throttle body, or intake duct using the original mounting point and wiring connector. Whether replacing a failed sensor or correcting a check engine light, Walker Intake Manifold Temperature Sensors restore precise air-temp monitoring for improved combustion efficiency, drivability, and emissions performance.
Characteristics include:
OE Replacement Calibration: Matches original resistance curves, response rates, and connector configurations for seamless integration.
Exact OE Fit: Designed for 100% compatibility with factory intake manifolds, air ducts, or throttle bodies—no modification required.
Measures Intake Air Temperature: Sends real-time air temp data to the ECU for accurate fuel delivery, ignition timing, and emissions control.
Restores ECU Accuracy: Helps eliminate drivability issues, rough idle, or fuel trim faults caused by inaccurate air temperature readings.
Durable Sensor Design: Built with heat- and chemical-resistant housings to withstand under-hood conditions and intake air exposure.

Overall rating: 4.8 / 5 from 704 reviews.
Service excellent et très ponctuel, merci beaucoup !
You can’t beat their prices, nor can you beat the quality of the parts. The fit and finish was just like OEM. This is the second time I’ve gotten brakes from these guys and each time has been an absolute win. Thank you parts Pioneer.
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.
