Today is my last day of legal driving. We found the new vsv I bought was faulty, so I bought another one, we tested it, it works. Check engine light came back on last night, still egr. Replaced all the necessary parts, egr, modulator and vsv, new vacuum lines, everything is clean. We are truly at a loss. Maybe 02 sensor? I read about it. P0401. Never ending. This sucks.

Possible causes for P0401:
EGR passage clogged (had this before, pull egr valve and clean built-up carbon from valve, tubing and passages in intake.) Faulty EGR Vacuum Modulator Valve Faulty EGR Valve Faulty EGR solenoid valve EGR solenoid valve harness is open or shorted EGR solenoid valve circuit poor electrical connection Dead (Weak) battery Faulty EGR temperature sensor and circuit Exhaust gas leaks Read more: https://www.engine-codes.com/p0401_toyota.html This post has been edited by 97GTinKC: Mar 20, 2018 - 1:53 PM |
