knock sensor sub harness

[Joe]

ok, some of you know my story, sone dont. cliff notes are horrible clutch problems caused by automatic pilot bushing (oops) parked the car to finish scool, swapped the ka back in to pass emissions now the RB is in and running BUT i have an extra plug.

its on the knock sensor sub harness, blue, 2 wire connector. i have a feeling that is what is causing my limp mode. what does that plug go to?

1997 240sx, Gen 2 RB25DET.

is it on the intake side of the engine?

i will look tomorrow, but it will prolly be the afternoon before i get back in the house, so hopefully you will have help by then.

if not maybe i will be able to help.

[Joe]

yes, intake side. its on the same loom and connector as the knock sensors.

the AIR control valve on the bottom of the intake.....

[Joe]

and thats one of the things the R33 manual lists as what will put it into limp mode...thanks mack!

any more detailed location? lol its hard to get under that manifold and look.

[Joe]

and this is different than the AAV on the top of the intake twords the firewall, correct?

[gawdzilla]

yea if you are staring at the AAV straight on, it is behind it, closer to the block.

[gawdzilla]

try this... its a 26, but should be similar im guessing:http://mysite.verizon.net/vze778xe/aac.JPG

see the blue plug tucked back there?

[Joe]

yep that looks to be middle of the engine way under the manifold

[jrou111]

That's on the top side of an RB20, correct?

[Joe]

i hate to be an *** but i still cant find it lol

this sucks

[gawdzilla]

try this pic? its of the intake side, looking from front to back. the dark plug is there to the right of the screwdriver, has a yellow wire coming out of it. http://mysite.verizon.net/vze778xe/aac2.JPG on the 26es it is under the intake manifold. not sure about 20s

turns out that blue plug is for the oil pressure gauge on the R33 cluster, my problem was the MAF wiring. the ****ty shop that messed up my wiring the first time before i finally did it myself extended the wires without soldering or using a butt connector, or any type of connector. all twisted.. oh well works now. out of limp mode
