is it necessary to mess with the wiring for the EGR lift valve solenoid and EGR lift sensor if i was running a chipped p28 with a block off plate?

no codes or problems NOT doing this are there?

got the info from jdmshit.com so if it's irrelevant or whatever, let me know that too....

 

P28 doesn't look for EGR, so you don't have to worry about it. The P13 Prelude ECU does so if you want to hook up the EGR, then you can go by the wiring info we have.

 

Newman is correct.

IF you are lazy and do not feel like opening a new page, there is what I wrote up in the big h22a thread in hybrid.

EGR Wiring Info

USDM wire colors are the same as JDM.

Connector colors means that when looking at the connector (wire pointing towards you) that the way they should line up (From left to right)

EGR lift valve solenoid
(The connector colors, From left to right) BLK/YEL and RED

Sensor Voltage - BLK/YEL - goes to A25
ECU trigger - RED - goes to A11.

EGR Lift Sensor (the actual EGR on the intake manifold)
(The connector colors, From left to right) WHT/BLK, GRN/WHT, and RED/WHT

ECU trigger - WHT/BLK - goes to D12
Sensor ground - GRN/WHT - goes to D22
Sensor voltage - RED/WHT - goes to D19 or A25

LOL.....you did better than most members on here by actually pasting it and not saying SEARCH!!! (have that info already ) but my question had nothing to do with wiring schematics or how to hook anything up, but whether or not it mattered with ANYTHING ELSE if these two things were bypassed, so no, this info, IF anywhere on the site, didn't come up in any searches......now it will

the question was whether or not it was necessary to have it hooked up for any other reasons.....I'm NOT gonna use an EGR valve or an ECU that looks for one, so it would just save time by not worrying with it at all.......but thanks newman, didn't think it mattered but knowing makes me feel better

 

This is good to know. I've been throwing code 12 ever since I put my motor in. Could you verify that code 12 is for the EGR lift valve solenoid? I am pretty sure it is since it is not wired up. I've got all the vacuum lines hooked up but not the wires.

My EX wire harness plug A at the ECU should already have the wires at pin A25 and A11 right? If that's the case then I would just need to trace them through the firewall and make my connections there inside the engine bay. Does that sound right Newman?

A25 it just sensor voltage, you can get it from a lot of different places. You do not have to cut the wires, just splice into them.

 

P13=EGR,Knock sensor,resistor box needed

Chipped P28= none listed above,but it will run rich...most of my friends with 5th gen H22A hatches use chipped P28's and a VAFC. hope that helps...hit me up if you have any more ????'s
