Review on YCT Engine Water Coolant Temperature Sensor: Fits Toyota, Lexus, Mazda, Ford, GEO - 89422-20010, 89422-33030, TX40T, 89422-35010 by Robert Berio

Toyota Tacoma 2000+ CEL code p115, ECT sensor 1. I've already replaced it at least once and thought I had a malfunction. Finally got this one and CEL stayed away. For some time. After a few months it came back so I checked my coolant, topped it up and everything was fine. Then, after a recent tweak, it came right back. After a few cycles it would turn itself off and then back on. Finally decided to shake things up and pay $25 instead of $10 for the brand and have been away from CEL for a week so far. This one returns.
