Dying for a harness

[white92frankn]

Hello guys I did some surface searching on a few routes to overcome this hurdle. I have a chipped p72 with stock h22 map on it. Ran like normal until motor spun a bearing. I bought another h23 block with h22 head and had both rebuilt to or specs. Installed motor and now I have a CEL code 03 MAP sensor. What caused this to happen? Thanks guys! BTW my mechanic is referring me to get a custom harness from rywire or monotech..

Just a guess... but perhaps your MAP sensor went bad?

I never had it plugged in

is that the only CEL you're getting? maybe you mixed it up with the plug for the TPS.

or, you used to have the Accord MAP sensor hooked up, without realizing it. Because the car won't run without the MAP. The stock map sensor is mounted to the firewall (inside the black box) and is connected to the motor via a Vacuum tube. I think maybe when you hooked up the new motor, the MAP tube got hooked up to the wrong nipple on the manifold (or not hooked up at all?)

Car don't start with either plugs connected to map. The ecu has a stock h22 map chipped to it and never had the plug connected and still ran like normal after I got it chipped. But after installing a rebuilt h23/22 the cel is on.

Also the accord map box on firewall has been removed.

Any info??

Car does run without map connected. Doesn't run right. Running way too rich... don't know what's next fellas..

Sounds like you need to address your wiring. Wire it correctly, and use a map sensor that you know works. Anything else is a halfassed solution, and you're not likely to find that here.

That's what I have been contemplating. I'm going to correct my harness and ecu issue and see if the cel goes away.

That seems to be the only option. If plugging an important component in causes problems, there's definitely something wrong, either damaged or misplaced, in your wiring. It's tough to diagnose it any further, since custom work has been done.
Check your vac connections as well, as cpmike mentioned.

Will do Sir, Thanks Guys!!!

Found the culprit

So the pins on the connector for map sensor were mixed up for pin B and C. Switched them, reset edu, CEL came off and stood off. Just runs a bit flat after 5-6k. Any info on why it's doing this?? I'm running a chipped p05
