Ok I was checking all the wires for my mass air converison and I found that my engine coolant sensor is capped and unplugged. Why is that, should I plug it back in?

jrichker said:Yes, the ECT is used to help set the fuel mixture. If it doesn't sense the coolant temperature correctly, it will not feed the computer the right info to set the correct air/fuel ratio.
you have the two coolant sensors/senders confused. the ECT (in the pic) is used by the computer to tell it how warm the coolant is. the gauge sender (located to the driver side and slightly behind the dizzy) is for the gauge only. that is the one you remove for an aftermarket gauge. one can use another source for the stock gauge, if wishing to retains its function (dont use a Tee fitting). post if interested in other locations. the front stock gauge sender location is the most accurate. DO hook your ECT back up if it is removed.evn_05 said:Hey i took mine out and replaced it w/ the autometer one for my autometer gauge and never hooked up the stock wire to anything. I asked this before and somebody said the computer does NOT use the ECT for anything. If this is soo please clarify... maybe this is why I get bad mileage.
Would you have a reccomendation for a spot to put it in if I do need to hook it up b/c my autometer is in the stock location at the front of in the intake manifold.
