MAT sensor
89 Jeep Cherokee 4.0 and all the bells and whistles
I'm picking up new O2 and Map sensors and figured I might as well replace the MAT also. Ok, O'Reilly's doesn't list one even after using ever acronym and word combo I can think of. So anyone know where I can get one other than the local jeep dealer? BTW, we have AutoZone, O'Reillys, NAPA, I think an A-1 auto parts stores. HA-A-A-A-A-ALP!!!!!!!!!!!!!!!!!!!!!!!!!!!! Budd (now so broke he couldn't put gas in it if it were 29 cents/gal.) --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com --- news://freenews.netfront.net/ - complaints: --- |

I think those were common across most all the 4.0 engines. http://www.acmejeepparts.com/products/55121_0003.htm http://www.jeep4x4center.com/sensors...e-xj-sj-mj.htm |

Those usualy don't go bad From the 88FSM MAT Sensor 1) Disconnect wiring from MAT sensor. Using high input impedance digital volt-ohmmeter (DVOM), check resistance of sensor. Resistance should be less than 1000 ohms when engine is warm. Replace sensor if it does not fall within range shown in TEMPERATURE-TO-RESISTANCE VALUES table. TEMPERATURE-TO-RESISTANCE VALUES (CTS & MAT SENSOR) TABLE F . C . Ohms (Approximate) 212 . 100 . 185 160 . 70 . 450 100 . 38 . 1600 70 . 20 . 3400 40 . 4 . 7500 20 . -7 13,500 0 . -18 . 25,000 -40 . -40 . 100,700 |
