Review: I own a 2007 Honda Civic Si. The sensor seemed faulty as a CEL was thrown and I scanned and discovered a p0128 code (Engine coolant related). My first thought was the thermostat but also found via online searches that it can also be due to a faulty ECT sensor. Honda quoted me $82.99 and though it was in stock, the desertcart seller listed it for $46.92 with 2 days prime shipping. It was a no brainer. Installation, I'd give it a 3/5 stars difficulty wise as it was fairly straight forward, but quite a pain to access while the engine is in the car. I had to remove my complete stock intake air box (didn't need to remove the intake arm). There is also an engine harness that is clipped onto a small aluminum/steel bracket that prevents you from accessing the sensor and clip which needs to be removed using a 10mm socket and ratchet (assuming you're able to unclip the large plastic cover that clips the harness to the bracket), and a deep 17mm socket would not clear the sensor as there's a metal hose blocking access. Thankfully I had a 17mm gear wrench that fit the sensor and allowed extraction. The oem O ring was stuck in the engine which I took out using a small flat head screw driver. The problem looked like an oil leak filled the sensor clip which may have failed. The sensor was also worn and looked a bit rusted. Once installed, everything is cherry. I'd highly recommend it. ## Features - Pilot '09-'14 (KA/KC/KX) - Genuine OEM - Direct fit - Genuine Honda Parts 37870-RTA-005 Water Temperature Sensor Assembly ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00C2M8U38 | | Item model number | 37870-RTA-005 | | Manufacturer | Honda | | Product Dimensions | 2.54 x 2.54 x 2.54 cm; 31.75 g | ## Product Details - **Brand:** Honda - **Item dimensions L x W x H:** 25 x 25 x 25 millimeters - **Material:** Inferred: Corrosion-resistant alloy, likely Stainless Steel or similar - **Measurement accuracy:** High - **Style:** Modern ## Images ![Honda Genuine 37870-RTA-005 Engine Coolant Temperature Sensor - Image 1](https://m.media-amazon.com/images/I/61REnUaI-ML.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by K***Y on 20 September 2025* Worked and for a great price! ### ⭐⭐⭐⭐⭐ Review *by J***G on 23 January 2023* I own a 2007 Honda Civic Si.
