Mack Ch 1999 Check Engine Codes

Recommended Posts

Hi there

I am new in here, and I hope that you guys can help me out. I have a 1999 Mack CH truck, and the check engine light is on, is giving me the 32 code. Now, what I need is to know what the code 32 means, what could be wrong with my truck. I really appreatiate your help

3-2 blink code is for erratic or missing rpm/speed sensor. check your connections to the tach sensor. I believe it is located somewhere in the bell housing. round and threaded with wires coming out of it. near the ring gear. (the computer counts the teeth in the ring gear to determine rpm etc. Good Luck
