Has anyone done the engine coolant temp. sensor mod on 99 1mz motor? Toysrme says that you can locate the correct wire to install the potentiometer on by using a repair manual. I couldn't find one identifying the specific wire. I appear to have two sensors below my water pump. One with two wires (to the right when facing) attached and one with just one wire (directly below). Any help with the identification would be helpful. Would include pictures but learning how to to that would be longer that this rambling post.

Is this one of those mods on ebay? If so I have done it on my 02 1mz.

It is typically the one with the GREEN cap. This mod doesn't do really do anything in terms of performance. Although it did fix my low idle.

Not an ebay Mod. Toysrme from this forum has written it up.

Brandon is unfortunately banned from these forums, the ECT mod is basically the IAT sensor mod on ebay, cept it will work on our camrys. Camry's have a "smart" ECU that detects and compensates any shifts in sensors like the IAT and quickly adjusts itself accordingly rendering the ebay mods useless if they did anything in the beginning. The ECT sensor is something the ECU can't overlook and will help get those idle rpms up!
