O.K.
I have the engine code-F22B2--just like PAHONDA said. I guess what Is throwing me
is the valve cover gasket. It says 96 honda accord,(In hand written grease pen)
Is it possible someone only
replaced the head on the engine with a different model year or is this just a
mistake made by the person who wrote it on there??. Behind the ashtray there is
what apears to be a factory cut hole where the plug should be but no plug just
an empty hole. Should I just start taking apart the dash to look for it or is there
a place that it has to come throgh the firewallinto the interior that I can track it from?????

 

The connector should come from the ECU (pass side on firewall).

If you pull the pass side carpet back and post the number on the ECU sticker, we will be able to tell if you can hook up an OBDII reader on there. There is no sense in looking for a connection that might not be there.

One way to tell if the engine block is OBDI or OBDII would be to look at the lower timing belt cover. On OBDII accord engines (96+), the crank angle sensor is mounted on the block near the crankshaft. If you see a wire harness coming out of the side of the timing belt cover, then the F22B2 engine you have in there is most likely a 96 engine, but that won't verify that the ECU is a OBDII. I'm sure that someone can wire up the OBDI harness to the crank angle sensor. In the OBDI accords the crank angle sensor is in the distributor.

 

am I looking for numbers on the back side of the carpet or numbers on the plate
covering whats looks like something electrical. I mean Its covered up but I can
see a liitle part of the cicuit board. On the back side of the carpet there is a sticker
that reads.

83301
A100-NH178LZ
021
is that anything??????????

 

It will be on the ECU. Sometimes Ebay is an excellent source to get a look at parts.

Here is a posting for a 94/95 ecm

That part number that they mention with #####-POA-.... is what I am looking for. You may need to unbolt the ECU to find the sticker.

 

there should be a VIN tag on the back side of the engine(kind of tough to get to, car has to be in the air, even then hard to read) but that would tell you what year the engine is.

 

PAhonda,

I think I have the number for you.
37820-POB-A5
381-153359
I hope thats right I hate to keep wasting your time.
thanks alot for all the help

For a 94 LX, the ECU number is 37820-P0B-A51. You might have forgot to type a 1 or maybe a 0 at the end. P0B is for the non vtec engine. It is also OBDI.

So I think you are wasting your time trying to find an OBDII connection.

Shorting that service connector should have resulted in the CEL flashing the error code. Did you turn the key to the II position or did you start the car?

You might want to check the wiring from that two pin connection to the ECU. You might want to reset the ECU by pulling the radio (backup) 7.5 amp fuse in engine bay box for a minute. Remember to have your radio code to reenter.

 

Wil do all suggested and get back with findings.
thanks again

PAhonda,

YOU ARE THE MANNN!!!!!
I went back to the link you sent me and very carefully followed all the instructions
and BINGO!!! I am off and running with my first code and thanks to your link I
think I know what it is.6 short flashes repeated over and over. The link says
ECT SENSOR So thats where I will start. I guess the first time I didnt jam the
electrical quick connect up In the plug end good enough.Thank You Thank You
and Thank You!!!!!!

I'm glad that you got it figured out.

That link above has the shop manual for a 94 accord. Download the fuel and emissions pdf, and there is a testing procedure for the ECT switch. Page 11-3 shows the location and 11-44 has the troubleshooting procedures.

Follow them, and you should be able to isolate the problem.

Good luck.
