DIYers, I'm having a check if a time locating and replacing my valve. The reason for changing is because I don't know what else to change with the P0410 code i keep getting from my obd 2 scanner. I've replaced the secondary pump, check valve, solenoid and checked all the tubing, but I keep getting the trouble code. The eg r valve is the only remaining option, unless I'm missing something. Any help regarding this issue would really be appreciated.
