I finally made it ! After long hours of work and a few cut on my hands, there in. I did piggy pipes.
My friend weld the new O2 Bung behind the main cat and so on... Idid the install. I road test the car,
it worth the effort. Great throtle response quiker spool from turbo's, sensible HP gain but idid get a CEL P1120. I would like to know if some of you did get a similarCEL with Piggy pipes install or meaby i just damage a wire on the O2 sensorwhile working on the car ?Any idea ???

O2 Sensor Heater Circ. this is the code

This is either a bad, unplugged or misplaced o2 bung.

Several people that have tried to do there own piggies havemisplaced there 02 relocation and end up with CEL's

 

Im not sure if it was the same code. But a local guy got the same code after trying to do his own piggies. He ended up taking them to VAST and they fixed what I am assuming was the o2 placement and the code whent away

But check the 02 first as you said it my be dammaged

Baskin now that I have all the go fast parts on my car can I get another shot at the title?

 

Thanks for your help
I also end up with CEL P0154 B2 S1 O2 No activity detected (rear one driver side ?). I've checked connection
yesterday and everything seemed fine. Im gonna use my spare O2 for testing tomorow and keep
you posted for results.

PS Happy New Year all [8D]

For theO2location, there is not a lot of places where the O2 bung can be placed behind the main cat.
Considering you have fire wall on the left side and drive shaft on the right side (4 driver side + opposite for pass side). There is no room on each side of cat + under it, is not an option so... All it's left to place it, is back of the main cat on top with a slight angle toward the rear and the center of the car, in betwin fire wall and drive shaft. Simetrically placed on each side. I honestly dont know where than can go elsewhere

 

the heater circuit code wouldnt be cased by bung placement, more like internal short or damage to sensor. no activity code is basically a bad sensor code. B2S1 is passanger side front sensor.

 

Problem Solved
P0154 B2S1 sensor circ no activity
P1120 B2S1 Sensor heater circ open
It was B2 S1 faulty 02 sensor. Just to clear up the confusion about where is Bank 1-2.
Bank 1 is passenger side
Bank 2 is Driver side
S1 is heater 02 located in front of pre-cat
S2 is located in front of main cat (behind it in case of a Piggy pipe job)
have a nice day
