he means a leak detection pump. very common failure on chrysler products. you can test through a scan tool. the part is about 149 and the labor is 1 hour.

P0442 - EVAP System Small Leak Detected. The NVLD stands for Natural Vacuum Leak Detection. Sounds like they are saying you need a new NVLD vacuum switch. There are a handful of reasons this code can go off all of which relate to emissions. Loose gascap, A small leak/hole in a fuel vapor hose/tube, and so forth. Generally they'll do a smoke test to find where the leak is coming from, but the easiest thing to check first is the gas cap.
