Code 23 MAT Low - ZR-1 Net Registry Forums

32valvesftw · 07-12-2016

I have ECM Code 23 Manifold air temperature sensor low. the Wiring looks OK so its probably the sensor. Odd thing is that the SES light only comes on when I am idling. As soon as I get moving for a minute or two the SES light goes out. Its been very hot here in Houston so I am wondering if the sensor is just overheating? Oil and water temps are hot when stuck in traffic but no more than 3/4 of the gauge for water. middle for oil.
So my question is this seems like a good time to do the MAT relocation mod to the airbox or further out in the breeze. When you do that I assume you leave the old sensor in place and just buy a new one and an extension pig tail to wire it? or do you put a plug in place of the old sensor? Also is failure of this sensor a common event?

Thanks
