throwing 15 then 1 then 1 again and repeats the process. I know 15 is IGNITION OUTPUT SIGNAL/ECU and then it throws 1 twice. HELP. and how do I fix it?

 

1 O2A - Oxygen sensor #1
2 O2B - Oxygen sensor #2 *not all cars*
3 MAP - manifold absolute pressure sensor
4 CKP - crank position sensor
5 MAP - manifold absolute pressure sensor
6 ECT - water temperature sensor
7 TPS - throttle position sensor
8 TDC - top dead centre sensor
9 CYP - cylinder sensor
10 IAT - intake air temperature sensor
12 EGR - exhaust gas recirculation lift valve
13 BARO - atmospheric pressure sensor
14 IAC (EACV) - idle air control valve
15 Ignition output signal
16 Fuel injectors
17 VSS - speed sensor
19 Automatic transmission lockup control valve
20 Electrical load detector
21 VTEC spool solenoid valve
22 VTEC pressure valve
23 Knock sensor
30 Automatic transmission A signal
31 Automatic transmission B signal
41 Primary oxygen sensor heater
43 Fuel supply system
45 Fuel system too rich or lean
48 LAF - lean air fuel sensor
54 CKF - crank fluctuation sensor
58 TDC sensor #2
61 Primary oxygen sensor
63 Secondary oxygen sensor
65 Secondary oxygen sensor heater

 

are these codes for all applicable honda crx ecu's or just for the si ecu ?

 

it's all honda ecu's
all honda has done over the years with the pre-obd to obd-II ecu's is change pinouts and added more codes as more and more sensors and features were added to the engines.
