First did you reset the computer after replacing the EGR valve if you don't the computer doe'nt reconize the new sensor so it doe'nt reset the peremiters.Then check all passages and lines in the intake manifold there could be a clogg somewhere.Go to www.rockauto.com and you'll find EGR pressure sensor for under $30.00.

This could be a fault with the shift valve, hopefully just requiring cleaning. This is accessible with the trans pan removed, best done on a hoist.

What's wrong with the code P0401 for camry 96


P0401 OBD-II Trouble Code
Insufficient EGR Flow
What does that mean?
EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve, an actuator solenoid, and a differential pressure sensor (DPF). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0401 code means that OBD detected an insufficient amount of EGR.
