devil4u2c Posted May 13, 2010 Report Share Posted May 13, 2010 (edited) Okay so my daily driver is a 1991 Pontiac Sunbird Convertible, and the check engine light came on the day I bought it. I finally got around to checking it and it came up an error code 25. So I went to Autozone and they let me look it up and it was a MAT sensor, not MAP or MAF, but MAT. I clarify because I had to with every other person I have talked to about it. Anyways if anyone knows what the hell a MAT sensor is and what it looks like lol, that would be a whole lotta help. Thanks Guys. Also if this is in the wrong section please move it an my apologies ahead of time. Edited May 13, 2010 by devil4u2c Quote Link to comment Share on other sites More sharing options...

JCiarlino Posted May 13, 2010 Report Share Posted May 13, 2010 That's the Manifold Air Temperature sensor. It's attached to the Intake Manifold. Should look something like this... http://www.autozone.com/autozone/catalog/parts/partsProduct.jsp?itemIdentifier=438883_0_4155_&skuDescription=Dorman+/+Connector-Manifold+Air+Temp+Sensor&brandName=Dorman&displayName=Connector-Manifold+Air+Temp+Sensor&categoryNValue=15799999&sortType=&store=2124&isSearchByPartNumber=false&fromWhere=&fromString=search&counter=0&itemId=2651-0&navValue=15702651&filterByKeyWord=manifold+air+temperature&productId=438883&searchText=manifold+air+temperature&categoryDisplayName=Electrical+%26+Lighting&parentId=57-0 Quote Link to comment Share on other sites More sharing options...
Loudcivic Posted May 13, 2010 Report Share Posted May 13, 2010 MAT stands for manifold air temperature and is usually located in the airbox or around that area and also sometimes in the intake on certain cars. it can also be called the IAT which mean intake air temperature. look at this page you can get an idea were it may be and go from there. http://www.google.com/imgres?imgurl=http://www.lunghd.com/Tech_Articles/Engine/Basic_Sensors_Diagnostics/MAT_sensor.jpg&imgrefurl=http://www.lunghd.com/Tech_Articles/Engine/Basic_Sensors_Diagnostics.htm&usg=__aqCWk9kqcK9RlvdJIbf5IIoFmTg=&h=346&w=461&sz=33&hl=en&start=1&sig2=yjcWYfjnTLPV9ZJHwHzCgw&um=1&itbs=1&tbnid=3OE3tnKlmTMBwM:&tbnh=96&tbnw=128&prev=/images%3Fq%3Dmat%2Bsensor%26um%3D1%26hl%3Den%26sa%3DX%26tbs%3Disch:1&ei=Z0zrS7HHFML6lweC4IWcBA Quote 2015 silverado crew cab nothing atm but soon...
