Coolant Temperature Sensor Middrivr 12V Analog Model 37870-PLC-004

Description

Product Overview

The Middrivr Coolant Temperature Sensor is engineered for modern automotive applications where precise temperature feedback is essential for engine performance and longevity. Built to OEM specifications, this sensor replaces part numbers 37870‑PLC‑004, 37870‑PNA‑002, and 37870‑PNA‑003, offering a direct swap without the need for additional modifications. Its compact dimensions—1.97 x 0.51 x 0.51 inches—and lightweight design (0.03 kg) make it an unobtrusive yet critical component in the cooling system.

Key specifications include a maximum supply voltage of 12 V, analog output type, and a measurement accuracy of ±1.5 %. The sensor operates reliably up to an upper temperature rating of 300 °C, providing a wide safety margin for high‑heat environments. Constructed from corrosion‑resistant materials, the sensor resists rust and chemical degradation, ensuring a long service life even under harsh conditions. The flange‑mount design simplifies installation, allowing technicians to secure the sensor with standard tools and minimal effort.

Usage

This sensor is ideal for a variety of Honda and Acura models, including Civic (2001‑2011), Element (2003‑2010), Pilot (2005‑2008), Odyssey (2005‑2006), CR‑V (2002‑2006), RL (2005‑2008), TL (2004‑2006), and many other compatible vehicles. It fits seamlessly into the engine coolant circuit, providing real‑time temperature data to the vehicle’s ECU for optimal fuel mixture and emission control. Whether you are performing routine maintenance, replacing a failed sensor, or upgrading an older system, the Middrivr sensor delivers consistent performance.

Installation requires disconnecting the battery, removing the old sensor’s connector, and using a wrench to unscrew the flange. The new sensor is then positioned, tightened to the manufacturer’s torque specifications, and reconnected. Its analog output integrates directly with existing gauge clusters or aftermarket monitoring devices, making it a versatile choice for both OEM repairs and custom builds.

FAQ

What vehicles are compatible with this sensor?

The sensor fits a broad range of Honda and Acura models, including Civic (2001‑2011), Element (2003‑2010), Pilot (2005‑2008), Odyssey (2005‑2006), CR‑V (2002‑2006), RL (2005‑2008), TL (2004‑2006), and other vehicles that use the OEM part numbers 37870‑PLC‑004, 37870‑PNA‑002, or 37870‑PNA‑003.

How do I install the sensor?

Begin by disconnecting the battery and draining a small amount of coolant to relieve pressure. Remove the old sensor’s connector, unscrew the flange, and replace it with the new Middrivr sensor. Tighten to the recommended torque, reconnect the electrical plug, refill coolant, and reconnect the battery. The process typically takes 15‑20 minutes for an experienced technician.

Is the sensor compatible with aftermarket gauge clusters?

Yes. Because the sensor provides an analog voltage signal proportional to coolant temperature, it can be interfaced with most aftermarket gauges that accept a 0‑5 V input range. Ensure the gauge is calibrated for the sensor’s output range to achieve accurate readings.

What warranty does Middrivr offer?

Each sensor is covered by a one‑year limited warranty against manufacturing defects. If the sensor fails within the warranty period, contact our support team with the purchase details, and we will arrange a replacement or refund according to the warranty terms.

Can I use this sensor in high‑performance or racing applications?

The sensor’s robust construction and high temperature rating make it suitable for performance vehicles that operate under elevated thermal loads. However, for extreme racing conditions where temperatures may exceed 300 °C, consider a specialized racing sensor designed for higher limits.
