Code P0401

Oh, maybe @mechanicjon knows how to get it. He seems to post a lot of images from the digital fsm... Actually I think he's linked it before in a post, don't memba for sure though.

 

I downloaded mine quite some time ago, and use it all the time. It used to move around from site to site, until Toyota would catch up to it and make them take it down. Maybe machanicjon can post that section. It's a few pages long. He has posted others.

 

Just sent him a message hopefully he can help.

I checked hoses for leaks and noticed the hose that goes from the PCV valve to the ?intake? was lose. The clamps weren't even clamping tight enough. There was some play. I went to a hardware store and bought a pair of steel hose clamps and clamped it good. I also checked every single hose coming from the VSV to the EGR to the Modulator. I even took the time to kinda blow the hoses one by one. Every single one of them are in good condition. I hope the problem is the PCV valve hose because the P0401 code went off shortly after replacing the pcv valve.

 

PM sent...

 

Thank you sir

 

Link to download for 2003 FSM is in his post #82 in the sticky. I see it there, and it looks like the one I have. My copy is not on this device, and I don't have enough free memory to try to download a copy from the link.
