I need help finding this sensor and what this sensor does?

 

So give us a clue what we are looking at. My guess is a GSL-SE part maybe?

 

yes is a rx7 1984 gsl-se

 

You can find it in the service manual here: Foxed.ca

 

it would have been helpful to say its an intake air temp sensor for a GSL-SE....

the GSL-SE one is NLA, but you can use the FC part and put the GSL-SE wires on it. N326-18-845

 

thanks!

 

Typically, the way these fail is that the wiring gets frayed riht at the base of the temp sensor, and then breaks off. Know that you can use a hot soldering gun to melt down the black plastic material at the sensor to give you enough wire exposed to resolder the wire onto it. Easy job, and with some heat shrink tubing of proper size, it will never break again.

That #2 Intake Air Temp Sensor is used by the ECU as a comparison to the the same sensor located at the Air Flow Meter to determine EFI map conditions for a hot start, i.e., same = cold engine, different = hot restart.

 

thanks for the info, i'll try to do that!
