Question about 1994 Cadillac DeVille
When I press the off and warmer buttons to get codes, "PO48 Current" came up. What is this? Also what is "PCM?"?
Po48 is an EGR system malfunction in the PCM...powertrain control module AKA computer..brain....The EGR valve isnt opening when it should. Either it leaks or there is no vacuum supply or the passage is blocked with carbon
