Whats the name of the sensor right next to the coolant temp sensor? the coolant temp sensor is the one with 2 wires coming out and then theres one with like 4 right next to it. What is it and what does it do? This is on an 86 305 tpi.

 

I can name that car part in one picture.

 

Ulysses,

That is likely the cold start injector control. It senses coolant temperature and will operate the cold start injector for a period of time on the first start attempt. The ECM will only allow the control to function if the CTS and MAT sensors are below 104°F and within about ten degrees of each other.

Thanks. Im gonna replace the cooling temp sensor, since the thermostat didnt solve my overheating problems and since im gonna be replacing my waterpump tommorow i was gonna do the sensor and if that was related possibly to my overheating problems i would replace that while im there.

 

The cold start only has 2 wires, and if the car is starting up ok I wouldnt bother replacing that sensor. If its 4 wires, you are probably looking at the IAC (idle air control) which is actually not in the manifold base but rather the throttle body.
