so i have been finishing up with the first part of my project and i am geting a code i thick that it is code 5 map

Looks like HTML code. Just kidding.

Looks like Code 41 (Four long, one short) - Primary oxygen sensor heater

 

would some one have an idear? I have wired in a new o2 and new wiring to the ecu and still have the same code.

 

I am using an 94 accord ls ecu I believe it is a p0b

 

Well than it might be a 41, but that's what it looked like to me too.
Double check it and see if you get the same flash pattern.

It's possible you could be running rich/lean causing your 02 sensor to read wacky. It could also be giving that code if you have messed with your exhaust aka running with no cat

 

this is how i wired it in
D14 - ORG/BLU at O2 plug (engine harness side) - WHT (4 wire O2 plug)
D22 - GRN/WHT at O2 plug (engine harness side) - GRN (4 wire O2 plug)
A6 - YEL/BLK at O2 plug (engine harness side) - BLK (4 wire O2 plug) There are 2 BLK wires and either one can make either connection. The second BLK wire is connected to B1

 

? have i some how gotten an ecu uses 2 o2s I thought that the p0b was an obd1 ecu and used just the 1 o2 at the header

 

Definitely a code 41.

There are both OBD-1 and OBD-2 versions of the P0B ECU. What is the exact part number printed on your ECU? The last three numbers are important. 37820-P0B-xxx??

Also, what sort of oxygen sensor did you buy? Part number?

 

Sensor GRN -> GRN/BLU -> D22 ECU (SG2)
Sensor WHT -> WHT/RED -> D14 ECU (O2S)
Sensor BLK -> ORG/BLK -> A11 ECU (HO2S HTC)
Sensor BLK -> YEL/BLK -> (Junction Box) A25 ECU

 

if u look at this pin out u see that a11 is a egr pin do i still use it or was this typo

 

is the pob fussy about this type of stuff and shoud I just get a chiped p75 or some other non-vtec ecu

 

I'm pretty sure that pin out is for an OBD1 P06/P28 Civic/Integra. It states under A11, that it is EGR for the Civic SOHC and H22/H23.

Here is the Honda shop manual for the OBD1 94-95 Accord ECU diagram. It could be wrong but I haven't had any code problems with any of my wiring as of yet.



If you get a chipped ECU it will be more of a pain than fixing this problem. It is not the P0B ECU that is any more fussy than the other ECUs. It requires certain signals to be sent to the ECU from sensors on the engine. If those signals or voltages are out of spec. The ECU will throw a Diagnostic trouble Code (DTC/CEL/MIL) this is the same for every ECU not just the P0B.

 

would u have the wiring for the 2end o2 as well

 

AFAIK there is no allowance for a SHO2S on the OBD1 P0A/P0B ECUs. they only use 1 O2 sensor. The OBD2 ECUs have both the PHO2S & SHO2S.

Did you want the diagram for teh OBD2 ECU? I have them as well.

 

no, no need of them then just was told be a shop that i had one today ty

 

well the o2 heat code. I gorn and i have been putting some miles on my car. and i am geting an egr code would some one know the pin out for the egr system so i can wire that up right

 

The one labeled ESOL on the image above is your EGR solenoid. Located on the right side of the engine compartment.
RED -> A6
YEL/BLK -> 12v power source 7.5amp

EGR valve lift sensor, located on the intake manifold.
YEL/BLU -> D20 (Power)
GRN/WHT (GRN/BLU) -> D22 (Ground)
WHT/BLK -> D12 EGRL
