i take it that you have codes 9, 11 and 13 - correct?

code 9 on the DOHC ZC, D16A8/A9/Z5 is almost always the exhaust camshaft not correctly timed - the Cylinder sensor rarely is the cause as they seldom go bad - could also be the wiring

code 11 isn't one we get with the USDM ECU - it is the code for the IMA sensor which is unique to the D16A9 ECU - the D16A9 did not use a catalytic converter and O2 sensor - it used the IMA sensor instead - the sensor is located at the ECU - see picture attached

Edit: i believe the A9 only used the IMA in the UK and in the rest of Europe it used the O2 sensor

code 13 is the Atmospheric Pressure sensor and is located under the dash behind the kick panel on the same side of the car as the ECU - see picture attached - in the US, the OBD1 92-95 cars had the sensor built into the ECU

 

Ah so thats what that thing does on the ECU lol.

Ok that one I could sort when i find the plugs and wiring.

Code 13: I read that and had a look this morning. My cars OBD0 but 92-95. I didnt see anything but then again id pulled out the under dash heaters so maybe its bolted on there.

As for Code 9... What do you suggest I do about it? Im double checking the wiring, but I think its fine.

on our cars, the PA sensor is located on the side kick panel area (not far from the door) right behind the bottom of the dash - see picture

Code 9 - did you rewire the sensor on your harness? make sure that the wires are going to the correct ECU pins

 

Thanks Ill have a look for that.

On my Harness..I used the Harness that was on my D15B2 before. So I had to wire in the 2 extra injectors and the 2nd cam sensor. I also had to change the plug on the distributor becuase the one from my harness woudlnt plug into the dizzy plug. I didnt have any wiring diagrmas for this so i just matched up the wires as to how they were in the plugs ie slot 1 to 1, 2 to 2.

The 2nd cam sensor was ever so slightly awkward because the previous owner had cut the plug off with less then a cm of wire to work with. Im also just using a temp ecu pin to get it wired up until i can get a proper ecu plug pin

Now when i start the engine it has a searching idle and its not one constant note it kind of rumbles. Well sort of like this but with noise >> \_/-\_/-\_/-\_/

 

when you wired it for MPFI, did you swap the wires on the throttle position sensor?

searching idle is usually caused by EACV that is not working properly - can also be a vacuum leak, low coolant level or the TPS

for the Cylinder sensor on the exhaust cam, just try switching the wires and see if the code goes away (reset the ECU, of course)

the distributor wires just need to match colors on both sides of the connector (orange to orange, white to white, etc.)

 

another question for the Code 11:
did your D15B2 have the O2 sensor? if so, you may want to find a D16A8 ECU which uses O2 sensor input and use it with the O2 and forget about the IMA sensor at the ECU - you probably don't have wiring in your chassis for the IMA anyway

 

Yep. I switched the wires for the TPS Used a guide off here.

And yeah my D15B2 did have an O2 Sensor...But now I have nowhere to put one :S Im using the A9 Manifold which doesnt have a hole for one and the decat I have doesnt have an O2 Sensor hole. I actually have the IMA sensor with the ECU just not the wiring.

 

to wire up the IMA isn't too hard - you will need to make a couple of changes at the ECU wiring - the IMA has 3 wires, a 5volt reference signal (yellow/white), a ground (green/white) and a brown wire to ECU pin B20 - your chassis harness will already have a brown wire at B20, which is for the ignition timing jumper - the ignition timing jumper wire on the ECU with IMA is at C16 - C16 is where the O2 sensor goes on your chassis harness - you need to move the pin in the chassis harness from B20 to C16 - you then need to run a wire from B20 to the Brown wire (middle one) on the IMA - the yellow/white on the IMA can be connected to the yellow/white 5 volt reference on several sensors, like the TPS, the PA (if you find connector for it, this would be the easiest place to go) likewise, the green/white which is just a ground - you can tap it into any of the other sensor grounds like the TPS, MAP, PA, TW, etc. or you can just ground it, preferably to the engine

 

Thanks. Im sure I can do that. Ive had to make enoguh changes as it is.

Hopefully it should erase one code.

The BARO code I should erase simply enough too from your explanation.

Ill have a pl;ay about with the wiring for the CYP Cylinder Sensor but one question. Is it in the Distrubotr or the Sensor for the 2nd cam? Because Ive looked up wiring and it says the CYP sensor has two wires in the distributor

 

most all Honda engines have the Cylinder Sensor inside the distributor - the exception is the D16A1, D16A8, D16A9, D16Z5 and OBD0 DOHC ZC - all these are DOHC D-series engines - they all have a separate Cylinder Sensor mounted on the end of the exhaust camshaft and no sensor in the distributor

 

Ah thanks! Top man Very helpful cheers

 

Right. Got the Cam Sensor sorted. The temporary pin i was using was the cause. The wiring was fine.

Code 13 went after I plugged all my heaters back in

But code 11 still remains.

Ive wired up the IMA sensor as above. But nothing. To check ive taken pics:

IMA sensor with 3 wires

Brown wire from IMA (extended with blue wire) to ECU plug B20. B20 was moved to C16

Yellow/White Stripe (extended with red wire) tapped into yellow/white stripe wire running from ECU plug C

Green/white wire (extended with black) tapped into green/white stripe wire runnign from ECU plug a

Does that look all good to you? Or have i tapped into the wrong wires.

 

your wiring may be different, but here in the US, the ECU 'A' connector doesn't have any green/white wires - has green/black, but they are for the main relay - i think i would use the green/white that is at C12 - it is the ground for most of the sensors, like PA, TPS, etc. - yellow/white is o.k.

 

Ok cheers, Ill give that a go in the morning

Must say I love all the help I get on this site

 

Well got that one sorted! Just got to wire in the PA Sensor to stop the Atmopheric Pressure Sensor Code coming up.

Think I understand the wiring of it so should be fine with that.

Oh and my cambelt snapped, should have changed it. [/noob]

Will hopefully be fitting a new one 2moro and getting the car running properly!
