Hi, so I have a 1993 Honda Civic DX with a 94 spec B18C1. It's running a OBD-1 JDM P72 chipped with the Mugen program. So, the problem is, when I rip it, I get a Check Engine Light. I stopped the car, pulled the code, and it was 2 long flashes, pause, then 7 short flashes. So, therefore, 27. I tried to look up that code, but it is no where to be found, like it doesn't even exist. So, my question is, (after countless attempts of searching) what is that suppose to be? How could I fix the problem? Any input at all is greatly appreciated. Thanks.

 

The pause means u have 2 seperate codes, u got code 20 (Electrical load detector) and code 7 (Tps sensor), with ur tps sensor not working ur idle will be pretty high and will be difficult to drive ur car, check the connector to the tps sensor first, if u replaced the tps sensor during ur swap u need to calibrate it to .45V at idle. I wouldn't worry too much about the ELD at the moment though, this just means ur idle will be a little low when ur cars under load, fix the tps code asap though. Just ask if u need anymore help.
