Thanks guys, the engine shut down was lit too. What I did was unplug the sensor, I was originally going to replace with a new one but it turned out to be a wrong part, and then I decided to plug it back in and then I started up the engine up again, and the electronic malfunction light came off.

I got a 1998 Mack CH613 that shows the electronic malfunction light. I changed the radiator due to the old one leaking and after I replaced it I filled the antifreeze to the level. After start up the malfunction light came up and I checked all fluid levels and they were all fine. I also checked all sensors and harnesses and they were all fine. I checked the codes in the ON position and it showed 1-7. Now I read online that I should look in the owners manual. The problem is I don't have a owners manual and don't know what the code 1-7 means or where the problem is located. If you guys could help that would be great. Thanks

Hello All, my name is Martin and am from Chicago. My dad, my uncle, and I have a small business hauling dump trucks. We have 4 Mack CH613s. The Trucks are a '93, '96, and 2'98s and they all run great. I am very interested in Mack Trucks and would be on here for trouble shooting and other concerns with my CH613s.
