How-To Check your CEL(sticky)
5 Easy to Follow Steps: 1) Get a CEL 2) On the passener side, remove the kick panel at the floor. Behind it, is your ecu and a jumper plug. 3) Locate the jumper plug (Civic 92-95 is grey, 96-00 its blue). Its a 2 pin plug. (I am not sure if the connector is in the same location for all hondas..I assume so - I dont know all the connector colors...) For EK, there is 1 brown wire and 1 black wire For EG, there is 1 tan wire and 1 green 4) WITH THE CAR OFF, insert either a 2pin connector clip, or loop a thin enough piece of wire into both holes on the connector. 5) Back in the driver's seat, turn the key to the 'ON' position. The CEL light will come on at startup, like normal, but it will then begin to flash. **By counting the number of flashes, you can decipher the CEL #. SHORT flashes are single digits (1/2 second) LONG flashes are 10's (1 second) -----CEL # List----- 1 O2A - Oxygen sensor #1 2 O2B - Oxygen sensor #2 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 36 traction control found on JDM ecu's 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 circuit 65 Secondary oxygen sensor heater wire (black wires) 67 Cat Converter 71 random misfire cylinder 1 72 random misfire cylinder 2 73 random misfire cylinder 3 74 random misfire cylinder 4 80 EGR Valve/Line 86 ECT sensor - Cooling System 91 Fuel Tank pressure sensor 92 EVAP Solenoid/Valve/Vacuum Lines ----- Now, if you take your OBD2 car (with cel) to a place that has a scanning tool (IE - AutoZone) the #'s will be different -> 5 digit codes. If you go that route, the #'s are available here: http://honda-tech.com/zerothread?id=466877 (I have never used a scan tool, so I do not know the validity of that list.) ----- Now that you have the corresponding # for your light, you can begin to go about fixing it. How you do that, is your call, but there are lots of members here that can probably assist you with any issue. Once you have fixed the problem, reset the ecu, by either pulling the battery's neg. cable or pulling the ecu fuse itself. Good luck guys. Got chart from HT i figure if people dont know about it then they can at least see it here |

by "loop a thin enough piece of wire into both holes on the connector" do you mean just take a wire and put one end into one connector and the other end into the other connector? i was told there was ways to use a multi-meter to count the flashes..but this seems easier..just want to make sure im doing it right ha..i just did a swap and of course lights came on...want to see what the issue is rather than just guessing ha..

yea use a paper clip or something and just jump one wire to the other to complete the circuit
