ok so i have a 97 Civic DX, and a 95 D16Z6 (completely rebuilt), this motor is brand new and i didnt buy it with an ECU so i used an OBD2 ECU to get it primed and running until i could get an OBD1 ECU and the OBD2a to OBD1 jumper harness, and it wont rev past 2200rpm. Im not suprised that it didnt with the OBD2 ECU as it has no crank position sensor, but now that ive hooked up the jumper harness and OBD1 ECU it still wont rev past 2200 rpm.

anyone know what could cause this?

ttt

SoFresh1189

anyone?

cehcivic15

how does the car run until 2200? like **** or normal? does it blow black stuff out the exhaust?

SoFresh1189

with the OBD1 ecu it runs perfect until 2200 and i saw no smoke at all coming out of the exhaust. (i dont have a catback exhaust, its just the headers+cat, im waiting on UPS for my catback) i have a POS air/fuel gauge thats reading all the way rich, i put the stock fuel pump back in cuz i thought maybe it was getting too much fuel? but that didnt change it, it still cuts out.

cehcivic15

hmmm, thats a tuffy.. check just to make sure you didnt mix up your tps and your map sensor connectors...tps should have a red/blu wire and map should have a yel/grn or a yel/red wire

whats it doin at 2200, is it bouncin like a rev limiter? or does it die?

Check Engine light on? If so, check codes. Report back.

SoFresh1189

it just acts like its cutting out like a rev limiter. im positive the sensors arent mixed up because id switched them back and forth just to make sure which one goes where, it wouldnt rev over 1500 with them switched around and it didnt run very good at that.

i cant read the check engine lights with OBD1 ECU but i hooked up the OBD2 ecu to read the codes, while the car was not running it came up with

P1509
Manf Cntrl Veh. Spd.
Idle Speed Control
Auxilary Inputs

While the car was running it came up with,

P0335
Crank Position
Sensor A Circuit
Malfunction

P0135
02 Sensor Heater
Circuit Malfunction
(Bank 1 Sensor 1)

P1509
Manf Cntrl Veh. Spd.
Idle Speed Control
Auxilary Inputs

i fixed the o2 sensor, i think i just had it plugged into the wrong plug

SoFresh1189

out of ideas?

BrandonR

What do you mean you can't pull codes with the OBD-1 ECU? The reason the OBD-2 ECU is running like **** is because of no crank position sensor.

SoFresh1189

because i dont have access to an OBD1 scanner. i conveniently work at a parts store so i have access to an OBD2 scanner but we dont sell OBD1 scanners here and even if i could special order one its mega expensive

SoFresh1189

and i imagine it would still throw the P1509 code with the OBD1 ECU im not sure exactly what it means tho

lol wow. Not taking the time to USE THE SEARCH TOOL will cost you a TON of money, it's friggin stickied at the top of the eg/Ek forum. I'll sell you my "obd1 scanner" tool for HALF the price of whatever you can get!! the only "obd1 scanner" you need can be found in your home office supplies; a paperclip ftw

there is a plug near the ecu underneath the kickpanel that you jump by putting either a piece of wire or a paperclip in and it makes the check engine light flash on the dash and you read that to check the codes. Take 2 seconds to look it up yourself then go from there.

As for the weird idle, I just put a gsr in my Si and Had asimilar problem but I think what my problem was was the fact that I had the map and tps sensor plugs mixed up. Post back and let us know what codes you pull up

pepboys Obd2 sensor, 50 bucks. GREAT INVESTMENT.

mooze

use the jumper clip

im having a swap b18c on my 00civic si... rite now im having this same trouble and hoping to find out too.. plz help me with this too... its the same problem with the rev... its only at 2000k rpm when i rev... black smoke does come out maybe cuz im running too rich.. 255 walbro fuel pump.. when i rev it jump up and down and doesnt go any further.. but imma check on the map sensor.... plz help

fly_high_gsr

guys check all plugs and connectors they might been mixed up, 2 of my friends had same issue and it turn out to be tps and map sensor, also it could be map and icv sensor behind the manifold. Try to switch one by one and take it from there.

SoFresh1189

i switched around the tps and map sensor again last night just to double check, i had them right to begin with because when i switched it around it ran like **** and as soon as it got up to 2k rpm it just died. so i know the plugs are correct.

SoFresh1189

are you talking about the OBD2a to OBD1 jumper harness?? if so im using it.

cehcivic15

no, hes talking about taking a piece of electrical wire, like 3 inches long or so, and reaching up behind your glove box, there are two open plugs, on is a 3 pin plug, the other is a 2 pin i believe with green/white wires, and sticking your 3 inch piece of wire, one side in one pin, and the other side in the other pin(jumper) and your check engine light will flash telling you a code. do not use the 3 pin connector


as for the guy above with the idle issues with black smoke, switch your tps connector and your map connector around, you have them backwards

thanks alot bro... ill do that first thing in the morning

i switch it around but still doesnt work.. we're double checking all the sensor and connector to see if we did something wrong... but give us some updates thanks
