2022 Cat 299 D3 showed this code at the end of the day while cooling off for a couple minutes. It was still running; I was shutting down for the day. Anyone else seen this before? All Services are current.
For a better chance of a response try posting a machine Serial Number (there are 12 different models of 299D3), along with more details of the number reference for the Code that came up on the display. A photo would be even better.

DY906745 is the serial number
OK, so now the dog can see the rabbit......... 132-4 - Engine Inlet Air Mass Flow Rate Sensor: Voltage Below Normal. Troubleshooting - "Sensor Signal (Analog, Active) - Test". See attached. The problem is that you can only troubleshoot this code when it is Active. So if it was there a couple of days ago but is not there now then the procedure will not work. However I attach it here just in case it pops up again so that you will have it as a handly reference. The troubleshooting procedure contains a truncated electrical schematic. If you want a complete one for the machine just ask.
