For the knock sensor will it cancel out the Knock sensor code if i just connect the pinout to a ground? and will it be safe?

Also for the 2nd O2 sensor bung with the AN-R header has a bung welded but i was wondering if it mattered where i place the 2nd bung?

Thanks in advance

i think these are the things that are causing my CEL problems

Thanks in advance

You can, but you need to put some resistance to it and not just ground the wire or it'll throw the code right away. Use a 10K ohm resistor.

Yes, you can weld a nut onto the header and screw in the 2nd O2 sensor. The O2 sensors are not heated so you need then to be hot in order to send a good signal to the ECU. Thus, place the O2 bung up on the primaries and not on the downpipe.

10ohm 10watt resistor will be alright????

hmmm i have the 1st O2 connected on the downpipe cause that is where it was when i got the header is that ok?

10K = 10,000

With a PR3 or PW0, the O2 sensors need to be hot in order for the ECU to read them properly so placing them up on the primaries is required. I had them on the downpipe before and runs like **** until the car warms up. Look at a stock B16 cast iron exhaust manifold - the O2 sensors are placed up on the primaries.

 

ok thanks i'll def try out that resistor thing thanks... also i'm loving my HCP mounts and linkage tahnks!
