Whole Lotta Codes P0136,P0156,P0161,P0401

[enduro]

The P0156 P0161 and P0401 are on my 98 SVT with headers. I have a mil elim on front but not yet on the rear .

The P0136 is on my 96 -OEM manifolds just put back on.


Is Bank 2 downstream HOS(P0156, P0161) the one right before the main cat. Is bank 1 downstream (P0136) the easily replaced HOS on the radiator side?

How effective is the liquid electrical tape at sealing mils? I think the recent deluges of rain are causing these codes.

I'm also hoping the P 0401 will just be clogged passages behind the TB.

..... Bank 2 downstream HOS(P0156, P0161) .

Stand in front of the car. This is the one right of the Bank 2 exhaust manifold. It is the lower O2 sensor. The easiest one to change. The mileliminator is probably disconnected, or the connector is not installed properly or wet.

....... bank 1 downstream (P0136)

Firewall side. This is the one after the Bank 1 exhaust manifold. It is just about under the front seats, in the middle of the drivers' and passengers' . The mileliminator is probably disconnected, or the connector is not installed properly or wet.

.Very effective.

...I'm also hoping the P 0401 will just be clogged passages behind the TB.... Could be. .

Noticed you are from Calgary. You should check out Chongo. He used to be very active on the forums until he moved to Calgary.

mil-eliminators only go on the downstream O2 sensors ....
