Thanks Nuggets. That does look like it, however it is labelled as the Water Temperature Sensor for EFI. I want to make sure its right before I order a ~$50 part.
To explain that:
We don't use water. we use coolant. Toyota just calls it that way for some odd reason.
EFI stands for electronic fuel injecton. That part is done by the ECU. Therefore, when talking EFI we're talking ECU.
Last but not least: While the picture says ""ECU Coolant Sensor", We put coolant into our engines, we don't put coolant into our ecu's. So there is no coolant to check for excessive heat in the ecu.
So "ecu coolant sensor" translates to Water Temperature Sensor for EFI just fine.
That's the part you need. Nuggets is right.
