Cause :

The cause of the problem may lie in the knock sensor, as well as in the use of low-quality oil or in the breakdown of one of the components of the ignition system.This combination is associated with interruptions in the ignition cylinders of the power unit. The cylinder number is not indicated, therefore, the user must independently check each element, including compression.


Don't forget ! When a fault code pops up, CAT's Uptime Center is automatically notified via an cellular link, and it alerts the truck's owner by prearranged methods, usually email or phone calls.
