Could anyone refer me to a pic of what a 91 Carolla Temp guage sensor looks like? There like 3 of them on the thermostat housing???

that photo is incorrect.

the temp sensor for the gauge is the single (yellow) wire sensor. All other coolant sensors have 2 wires. The temp sensor gauge is self grounded.

The picture in the link above is for the EFI computer. The additional 2 sensors are for the CSI (cold start injector) and your radiator fan switch.

Thanks for the intel! Is this sensor around the others on the thermostat housing or on the block somewhere?
The autoparts sold me one and it wouldn't fit in any of the holes or fit into any of the harness plugs???
All 3 brass ends had much larger dia threads than the autoparts one.
Thanks
