2001 Toyota Camry Question: MIL P0401 EGR Flow Error but no failure found
Cleaned EGR Valve pintle and verified the diafram opens and seems to modulate at higher rpm and/or temp. Code is almost always active, but sometimes cleared for 20+ tests. Once in a while usually when gas low and very hot outside get P0446 Vapor Emissions. How do I fix and pass Ca Smog test???? - BuzzLinc
