My blue temperature light flashes continuously. I read that I need to replace my coolant sensor but I found out there are two. I actually have the old to wire sensor and the blue four wire sensor. AutoZone has the blue one in stock. But I'll have to special order the two wire if I need to replace that one. Any help would be appreciated.

Try to get a green one if possible, I got a blue one from Napa and it failed after 3 months. Sucks that we have the square plug, our sensors cost 5x more than all the others :(

The two-wire sending unit is for the temp light, the four-wire is for the engine management system (fuel injection).

I bought the blue 4 wire and it worked. Autozone has a limited lifetime Warantee on Duralast and it set me back $28. I will post if it ever fails. 15 mins to replace but the darn plastic tabs that hold the sensors in place are fragile!!!
