Product Details

The Airtex 5S1503 is a direct-fit engine coolant temperature (ECT) sensor designed to deliver accurate coolant temperature readings to the engine control module (ECM). Proper coolant temperature data is essential for optimal fuel delivery, ignition timing, and emissions control — making a reliable ECT sensor critical to overall engine performance.

Key Features:

  • Direct OE replacement for precise fit and function
  • Sends real-time coolant temperature signals to the ECM/PCM
  • Helps maintain proper fuel mixture and ignition timing
  • Manufactured to meet or exceed original equipment specifications
  • Corrosion-resistant construction for long-term durability
  • Plug-and-play installation — no modifications required

The Airtex 5S1503 coolant temperature sensor is engineered for hassle-free installation and reliable long-term performance. Also cross-referenced as TS337T, this sensor is a trusted solution for restoring accurate engine temperature monitoring and preventing issues such as rough idle, poor fuel economy, and failed emissions tests caused by a faulty ECT sensor.

Great price and good company to buy from!

Wow...best price on the internet and receiving order in four days!<br>Very impressed

I ordered CV axles from Autoplicity and had them in less than a week! Definitely the best prices for quality product on this item. Will be a return customer for sure!

I was apprehensiveness at first to make a major purchase with Autoplicity due to their extremely low price and lack of reviews. I decided to take the chance and I am very glad I did. I made my order on a Monday morning at 0900 eastern time and my product arrived on Wednesday at 3pm. The item was exactly as described and the most astonishing part is that my purchase was released from the factory less than 45 days ago. I was expecting a model that had been sitting on a shelf for the last year and needed to be updated. That was not the case. I will definitely order from Autoplicity again in the future.

Very good price. Super quick delivery. Will def. buy from them again. Highley recomend them

Sweetest price on this K&N Filter anywhere! Shipped within 24hrs too. I'm coming back to shop for my car next.
