2002 p0141 & p0325 suddely showing up

[mcdlnwright]

Ok I had the Van serviced the other day, Just basics and suddenl I have a check engine light
I went to Da zone and it read P0141 O2 sensor
and p0325 Knock sensor

I seem to remember one can cause the other to pop but I cant guess which one. And is there a way to test them to be sure its bad without just replacing it and assuming its bad?

well the code for the O2 sensor you stated is for a rear O2 sensor Heater ( witch is part of the O2 ) Knock sensor code coudl have been there already, knock sensors do no turn on a check engine light. that is why.

repeat

does anyone know where I can find a guide to fix these?
I have replaced a 02 in my bronco and I am assuming its the same,
But I have never replaced a knock sensor before, And Its rather pricey so is there a way to be sure its bad? Is it possible it could be reading bad because of the o2?

Ok went to that zone and they said there is no repair guide for this year in both Haynes and Chilton's so no luck there.

No one had a o2 sensor < OEM> but they had a universal 4 wire available by bosh

I got a printout of the code for the Knock sensor
The Pcm has determined that a malfunction exists in the electrical circuit for the knock sensor 1 < bank 1 or single sensor> < bank 1 identifies the cylinders on the opposite bank>

Could this just be a blown fuse?
it also list possible cause of low fuel pressure could the o2 cause that?

come on guys help me out here please
