94 accord ex ecu pin chart?
anybody know a link to a pin out chart for either the 93 accord ex ecu or the 94 ex f22b1 ecu (POA)
ive read the FAQ threads and cant find anything |

A B D
12345678910111213 ........... ......... 14151617181920212223242526 is how it would be numbered? if i was looking at the ECU. |
Re: 94 accord ex ecu pin chart? (hon2984)
Oh yeah, sorry about that.
On the OBD1 ECU's the numbers are Odd numbers on top & even on bottom. https://i133.photobucket.com/albums/...obd1-pins2.jpg |
Re: 94 accord ex ecu pin chart? (GhostAccord)
much appreciated ghost!
by the way i checked out your ITB thread. Very nice! https://honda-tech.com/forums/images/smilies/emthup.gif how did you find out that you could use those throttle bodies from a suzuki? i know that you dont have to worry about vtec kicking in because of a CEL but how do you keep your car from going into limp mode because you dont have an IACV? |
Re: 94 accord ex ecu pin chart? (hon2984)
No problem https://honda-tech.com/forums/images/smilies/emthup.gif
As for the throttle bodies, you can use pretty much any throttle body. Be it single, double or quad. As long as it fits your car, you have a way to feed it fuel and tune it. The ECU ROM (program/basemap) that I will be using will not be looking for an IACV. The two rom editors that I have used, Crome & eCtune, have the ability to disable a number of items such as; IACV, VTEC, IABs, & A/C. Therefore your ECU doesn' throw a CEL if thoes items are removed from your car. Modified by GhostAccord at 12:33 PM 9/1/2008 |

Re: 94 accord ex ecu pin chart?
ok thanks but now another question the reason i need this is im trying too hook up an apexi neo afc controler all these abreviations arent really helpin i got power and ground now need to figure whick wire is rpm and throtle..... also arent you missing section d on pin out chart
|
Re: 94 accord ex ecu pin chart?
Sorry forgot to copy the D section. I made the correction/edit to above post.
The RPM signal output for fuel hacks does not connect to the ECU. I think the RPM signal wire you are looking for is the BLU wire that goes from the distributor to the back of the gauge cluster. It is the tach rpm signal wire. The throttle signal aka TPS or throttle position sensor is pin D1 (RED/BLK) |
Re: 94 accord ex ecu pin chart?
thank god for people like you lol this did the trick allset now thanks again.... and im probly gonna use the blue wire but my buddy told me i could use the crankshaft position sensor is he right or wrong if ya know lemme know thanks...

Re: 94 accord ex ecu pin chart?
If you are looking for an ECU wire to tap into the Neo diagram that I found shows that you can use the ICM signal from Pin A20 for the RPM signal.

Re: 94 accord ex ecu pin chart?
I have a 94 accord ex f20b1 and my ac does not work I already checked fuses,relays,compressor,Freon,and every thing seems to be fin except the compressor relay that does not ground when I press the ac button I have 3 grounds instead of just 2 and I was thinking it can be my ecm or tcm. Can yall help me out pls
|
When you ground the compressor does the compressor turn on ?
|
Re: 94 accord ex ecu pin chart?
I applied current to it an it would turn on I didn't need to ground it cause its grounded to the engine

Heater control panel Wiring A/C thermostat A/C pressure switch ECM/PCM This is how the system works: When you push the A/C switch ON, and the heater fan switch is in position 1, 2, 3, or 4, a ground input is provided to the ECM/PCM through the A/C thermostat and the A/C pressure switch. The A/C compressor clutch relay is grounded by the ECM/PCM. When energized, the relay allows battery voltage to energize the compressor clutch coil which then engages the clutch. Although, the issue may be with any of the items I listed, many times on the 5th generation Accords, the A/C thermostat is the culprit. The thermostat probe is in between the fins of the evaporator. However, you should try to isolate the area of the issue first before replacing anything. |
Re: 94 accord ex ecu pin chart?
Thanks a lot and so the tcm does not have no do nothing with the ac?

Re: 94 accord ex ecu pin chart?
The TCM does not control the A/C compressor clutch relay. Although you'll see the TCM as part of the A/C circuit diagram, the way the flow is:
1) When the A/C switch is ON and the heater fan switch is in position 1, 2, 3, or 4, a "ground" input goes to 2) the A/C thermostat, which then goes through 3) the A/C pressure switch, which then goes through 4) ECM/PCM, the ECM/PCM will then send a ground input to both the A/C compressor clutch relay and the TCM. The TCM does not control the A/C compressor clutch relay. The ground input from the ECM/PCM to TCM looks like it will affect the transmission lock-up clutch when the A/C is ON. |
