Engine check light
I have a JDM b16a in my 88 honda Crx. The problem i'm having is that my Engine check light come on everytime i Reverse?does anyone know the problem?Also when i reverse my Tachometer would go up and down real fast....and then the check light would come on... the ECU blinks 2 slow and 3 fast...after that it would blink 6 fast....i've check the knock sensor and its pluged in...do i have to replace some sensors?
also is it neccessary to have the 2nd 02 sensor plug in? because when i had my old B16a headers it had 2 O2 sensor plug... but when i got my DC headers it only have one bung to plug the 02 sensor... so i just plug one 02 sensor in... is there a way where i can convert the wires to only read one sensor? thanx.

First an most obviously, a B16A in a CRX should not have a second O2 sensor. If it does, you're running OBD-2, which makes no sense. I don't know why you would have one, and if it throws no codes I would leave it out.
The knock sensor may be damaged. Code 6 is the coolant temp sensor, is it plugged in?
What ECU are you using? A PR3, a PW0 or something else?
