CEL CODE help x5
 

hey guys, new to site, honda-tech is giving me no answers. Hope you guys can. :canada:

I installed a 98 b18c1 obd2 into my 93 civic cx
obd2 p72 Ecu and 98 gsr harness.
Car is running rich, jolts when i shift.
I am NOT driving the car, just sitting in my driveway.
Over the past month i couldn't figure out what is wrong with the car. Car starts but these appear.

CEL CODES

3 - map sensor - i have switched the throttle sensor plug around with this sensor, bought a new Map sensor and the code is still coming up.

22 - Vtec pressure valve - i do not have vtec currently hooked up yet.

54 - CKF - crank fluctuation sensor - ?????

65 - Secondary o2 sensor (heater wires) - I connected the GSR secondary o2 sensor into my EG. Ran it as follows.

Green wire (signal wire) = D13
White wire (sensor wire) = D14
1 Black wire (heater wire) = A6
1 Black wire (heater wire) = A11
-----As stated on ff-squad.com------

I don't know to try and run one black wire to my battery or where a 12V output is.? I don't know where.

91 - Fuel Tank pressure sensor - This one is new and came up today while checking CEL.

I just need my car back up and running. I don't know what else i can do to get rid of the map sensor and to fix my secondary o2. New problems keep arising and running low on $.

If anyone can help me out And or give me opinions on how to do something different... much appreciated.

just out of curiosity, why did you choose to use a 98 GSR harness in your 93 civic?

You basically have the EASIEST car to do a swap in. I would have just re-used the stock 93 civic wiring harness, add the wires for vtec, knock sensor and IAB's, changed the alternator plug to the OBD2 style 4-wire square plug, changed the dizzy plug to the big square OBD2 plug and re-used your stock injectors (they're 240cc like the GSR ones) then either got an obd1 P72 ecu or chipped and modified your stock ECU and run a GSR program (you won't have to wire up the knock sensor if you do this and you can eliminate the vtec pressure switch)

If you do what I mentioned above this will solve your code 54, 65 and 91 at once. This is b/c the OBD1 ecus don't use a CKF sensor, secondary o2 sensor or fuel tank pressure sensor.

Whenever doing a swap, regardless of what engine into what car, I ALWAYS reuse the stock wiring harness and modify it to fit whatever engine is going in.

I thought it was plug n play according to ppl online. Which for the most part it was wit the stock Dseries harness.
I Didn't realize about the secondary o2 sensor and such until i started reading more online that this problem occurs with obd2 engines and obd1 cars. That was after that ppl told me about that i needed to install that.

Do what zeeman said.

Re-use your obd1 harness, obd1 ECU and add the appropriate wires/connectors to the harness.

I'll see what i can do money wise.. Maybe i can get my hands on a obd1 chipped ecu and jumper off ebay. and just convert the rest..Just hope my buddy didn't steal my harness :confused:

edit - Any idea with the map sensor? i had no CEL in the GSR integra parts car before i swapped motors out. And keep getting this error in my civic. Would i need the civic mapsensor connected as well?

ya try the civic map sensor, its the same thing.

With my obd2 computer and obd1 car, wondering if i can just splice the Secondary O2 sensor into my o2 sensor. ?
