Ok so i ordered my chipped p28 ecu last week and it came last night. I put it in and a had a cel. This is on my 93 civic hatch with a b16a. I found that one wire had come loose, so i figured i would fix it this morning. So this morning I go out and then I dont know where the wire goes because they are not factory wires. the kid i bought the car from had them put in when his vtec controller got stolen. But i do get a code21. Now the next problem is a major one. The map sensor wire on connector d was taped together and it came apart. So i souldered it back together and now when i start the car it basically spits fuel out of the car. I need help ASAP!!! Even if your local to allentown we could meet up if you could help! Anyone please. The car barely runs now and and is dumping so much fuel!

code 21 is for vtec, probably the vtec wire got loose. i remember vtec is suppose to go to a4 and d6 on ecu pin. check if the wires popped off from those slot.

Yes i know to check those two places. Im more concerned about the map sensor white wire. I soldered it together and it still runs like ****. It is better than before. It atleast idles now, before it wouldnt even do that.

The code 21 is the vtec selenoid since you got a swap try to rewire the selenoid from the ecu again, this is how you do it. VTEC Solenoid Yellow/Green wire to A4
VTEC Oil Pressure Sensor Blue wire to D6
VTEC Ground Black chassis ground
this problem has nothing to do with your map sensor.

Read the original post!!! there are 2 problems. One is code 21. the other is a problem with my map sensor

Manny 77

Wire the map sensor wire white directly to the ecu is D17

offspringpunk14

So your saying I should replace the whole wire???

Manny 77

Just to be sure yea... if im you i would

ok. How do I pull apart the ecu plug to replace the wire?

J240sx

Theres clips actually holding the Wires in place. Flip the clip up and pull the Pin out.

Manny 77

you now what dont even pull the wire off just cut it with a few inches from the plug and continue with the new wire from there

Manny 77

here just in case you need it this is the pinout.
Here is a p30 pinout, you can use this as a reference because this and a p28 are basically the same and you can use it to figure what plugs a b or d and which way to look at it

well see thats what i did now...I have the battery disconnected to see if it resets the ecu.

Manny 77

well i hope you can solve your problem... let me know

Manny 77

as soon as you solve the problem the light will turn off right away you dont need to disconnect the battery
