Greetings,

Just had a new Edelbrock 3701 Intake Manifold installed and I am now getting Trouble Code 23. MAT Sensor (Low Temp).

My suspicion is that the MAT sensor is supposed to be mounted on the intake manifold itself and either the Edelbrock intake doesn't support it, my Mechanic didn't hook it up or the sensor is bad.

Please let me know which is right, what it is supposed to look like, where it should be attached and the implications if I never hook it up?

Please include a picture or diagram if possible

Thanks,

Big Ed

To my knowledge, there is no MAT sensor on carbed cars, but I could be wrong. My 84 doesn't have one unless it's the sensor that's in the thermostat housing.

For a carb'd car, code 23 is TPS. Make sure it's plugged in, the harness isn't pinched under something, etc.

Pardon my ingnorance, but what is a TPS and where does it plug in? Where would I look for it? What does it look like?

Thanks for your help,

Bi Ed.

Throttle Position Sensor. White plug on the front driver side corner of the carb.
