i have been running threw every possible scenario for the p1401 weather it is a alt voltage to high which i do not think it is now. here is what i did to get that code to go away lol'z. i jumped the brown wire white stripe at the tps sensor to the dpfe brown wire white stripe. now the code is gone but getting a different code p1120 pd there is reason for this.
btw just capped the brown white wire at the dpfe. the dpfe code is gone but the throttle position sensor low voltage input is up. most likely because i spliced in to it. according to my diagrams in my Haynes they are all connected off the brown white wire. the tps sensor the dpfe sensor and the fuel tank pressure sensor. so if i jumped it it should still work right? unless they got separate wired to each sensor so does that mean to rip the intake manifold upper of course and see what is going on under it?
any help would be appreciated cause it is a common wiring problem i am thinking.
