i have a 90 crx with b16a. the ecu is a pr3. the light is blinking two long and four short times. does anybody know what the f..k this code is.
 
24 = ?
23 = knock sensor
22 = vtec pressure switch
21 = vtec solenoid
20 = ELD (not looked for by PR3 ECU)
4 = CKP (distributor)
2 = second O2 sensor
1 = primary O2

I'd be willing to bet it is either:
23 + poor counting (knock)
23 + 1 (knock + primary O2)
22 + 2 (vtec pressure + secondary O2)

24 doesnt exist.
20 + 4 doesn't make sense due to the lack of ELD.
 
Then it's invalid. Ignore it and reset the ecu. If it keeps doing it, use someone elses ecu. If it keeps doing it, then your car is haunted. Deal with it. :D
 
pull your primary O2 and see if it changes. If it DOESN'T change the blink pattern, you have codes 23 + 1. That would be my bet.
