Wanted to share what I found with one of JohnGD reply's EGR Vacuum Modulator Valve on Gen. 3 Camry - Toyota Nation Forum : Toyota Car and Truck Forums over at Toyotanation...Thx,John.. Also, air blown into the hoses from the modulator's Ports P and R into the throttle body should flow freely into the throttle body. If these vacuum signal ports in the throttle body are blocked then the EGR valve won't work. I had previously cleaned the TB and my assumption is that i inadvertently plugged the ports when cleaning. So if you clean the TB and and you get a CEL,and the code is P0401,check these ports... |
