Engineered with a durable brass body and 1/8 inch thread, it withstands extreme temperatures from -40°C to 200°C. Featuring a rapid 10-second thermal response and complete connector kit, it’s the go-to sensor for professional-grade automotive performance and reliability. ## Description This product has sensor performance specifications with accuracy of more than 2 degree centigrade / 3.6 degree Fahrenheit and operating temperature of - 40 Celsius to 200 Celsius / -40 Fahrenheit to 392 Fahrenheit. The dissipation constant is 12 megawatt per degree centigrade and the ratio, at a specified ambient temperature, of the change in the power dissipation of the sensor to the resultant temperature change of the Thermistor. The test medium is silicone oil and thermal time constant is 10 sec. The time required for the sensor to achieve 63.2 per cent of its steady state value when subjected to a step change in ambient temperature [Tc= (Tf-Ti) x63.2%+Ti]. Sensor body material used is brass, thread: 1/8 inches -27 PTF, hex size is 1/2 inches, installation torque: 13.5Nm / 10 feet-pounds, weight of 12.2 grams, supply current: 5 Volt DC, electric termination: connector includes mating connector, pins and pin lock. Review: A bit pricey but good quality and has a data sheet. - It has a datasheet so it's nice an easy to use/map anywhere. Good quality product. Temp/resistance values have a slight curve. Check out the data sheet to make sure it works for you. Review: perfect replacement - Broke my old sensor and this works perfect! ## Features - One wire to sensor ground and one wire to sensor signal - Wire strip length is 0.175 inches to 0.200 inches - Thread size: 1/8 inches - Operating temperature: sensor tip -40C to 200C, connector -40C to 150C ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005AT11F4 | | Best Sellers Rank | #223,708 in Automotive ( See Top 100 in Automotive ) #1 in Automotive Replacement Fuel Injection Temperature Sensors #1,120 in Automotive Replacement Fuel Injection Products | | Brand | AEM | | Brand Name | AEM | | Customer Reviews | 4.4 out of 5 stars 57 Reviews | | Global Trade Identification Number | 00840879021795 | | Included Components | AEM 30-2012 Water / Coolant / Oil Temperature Sensor Kit | | Item Dimensions | 4.72 x 2.76 x 4.72 inches | | Item Type Name | AEM 30-2012 Water / Coolant / Oil Temperature Sensor Kit | | Item Weight | 0.04 Kilograms | | Item dimensions L x W x H | 4.72 x 2.76 x 4.72 inches | | Manufacturer | AEM | | Material | Aluminum, Brass | | Material Type | Aluminum, Brass | | Measurement Accuracy | < 1.5°C / 2.7°F | | Measuring Range | Operating Temp: -20°C to 150°C (-4°F 302°F) | | Model | 30-2012 | | Mounting Type | Threaded Mount | | Output Type | Resistive | | Part Interchange Info | 30-2012 | | Part Number | 30-2012 | | Smart Home Compatibility | Not Smart Home Compatible | | Specific Uses For Product | Temperature,Time | | Style | Modern | | Style Name | Modern | | UPC | 840879021795 | | Unit Count | 1.0 Count | | Upper Temperature Rating | 200 Degrees Celsius | | Warranty Description | Warranty | ## Product Details - **Brand:** AEM - **Item dimensions L x W x H:** 4.72 x 2.76 x 4.72 inches - **Material:** Aluminum, Brass - **Item Weight:** 0.04 Kilograms - **Style:** Modern ## Images ![AEM 30-2012 Water / Coolant / Oil Temperature Sensor Kit - Image 1](https://m.media-amazon.com/images/I/61BmTZtBD+L.jpg) ![AEM 30-2012 Water / Coolant / Oil Temperature Sensor Kit - Image 2](https://m.media-amazon.com/images/I/510aCSRO2-L.jpg) ![AEM 30-2012 Water / Coolant / Oil Temperature Sensor Kit - Image 3](https://m.media-amazon.com/images/I/51Zjd5lcyGL.jpg) ![AEM 30-2012 Water / Coolant / Oil Temperature Sensor Kit - Image 4](https://m.media-amazon.com/images/I/61BHF0HpsbL.jpg) ## Questions & Answers **Q: What is the ohm resistance on this sensor?** A: packard makes the original part 12160855,, you can find specs at mouser,, i could find no reference to ohm resistance **Q: Will this oil temp sending unit fit my 2005 nissan fronteir Nismo cre** A: It is unlikely to work with the stock threads and ECU. If you are using an aftermarket or AEM gauge, you can just get a thread adapter or if you are making an new hole, you can drill and tap it. The adapter is a common method to use US based gauges on Japanese vehicles with metric threads. **Q: Will this work with my AEM 30-5140 100-300F temperature gauge?** A: Yes AEM uses the same probe on their temp gauges **Q: Is this sensor 1/8 npt or 1/8 bspt?** A: The thread size is 1/8" - 27 NPTF ## Customer Reviews ### ⭐⭐⭐⭐⭐ A bit pricey but good quality and has a data sheet. *by B***T on February 27, 2015* It has a datasheet so it's nice an easy to use/map anywhere. Good quality product. Temp/resistance values have a slight curve. Check out the data sheet to make sure it works for you. ### ⭐⭐⭐⭐⭐ perfect replacement *by K***. on January 19, 2025* Broke my old sensor and this works perfect! ### ⭐⭐⭐⭐⭐ Link to MegaSquirt / TunerStudio definition files *by B***T on June 17, 2015* Works with TunerStudio / MegaSquirt, as an oil temperature sensor IF you have the correct files. I have worked out the files with the TunerStudio folks in this thread: http://www.msextra.com/forums/viewtopic.php?f=122&t=58859 The sensor seems well built and I have not had any trouble with it. I used it to measure the oil temperature in an aircooled VW bug, after making a custom fitting. ## Frequently Bought Together - AEM 30-2012 Water / Coolant / Oil Temperature Sensor Kit - AEM 30-2131-150 150 PSIG Brass Sensor Kit - AEM 30-2131-100 100 PSIG Brass Sensor Kit --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/14383887-aem-30-2012-water-coolant-oil-temperature-sensor-kit](https://www.desertcart.sg/products/14383887-aem-30-2012-water-coolant-oil-temperature-sensor-kit) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-05-21*
