Re: Cel Code (USDMEH2)
the Check Engin Light tells you wit will flash a certin amount of times and tell you what code your throwing
Here's a handy chart for pulling your ECU codes. Pulling the code is a fairly easy process.
For 92+ Honda's and 94+ Acura's:
Before you can start reading the CEL (check engine light) in your dash, you need to 'jump' your ecu. Here's how.
Located the factory two-pin connector of brown and black wires near the ECU on Civics del Sols and Integra's, or behind the center console for Preludes and Accords. Pull that 2-pin out of the main harness. Using a wire or paper clip as a jumper, connect the outputs of the harness together, so that the black wire and the brown wire make a circuit. Once this is jumped together, the dash will start the light show, so its a good idea to jump first, then turn to on.
For 88-91 Honda's and 86-93 Acura's:
The ECU's on these cars actually have a neat little window right on the computer case. No need to jump here- just turn it to on, and watch it right there through that window.
For both steps above, the output will be in a Morse code style of long and short lights. For example, 2 long, pause, 3 short is 23.
0 ECU 43 FUEL SUPPLY SYSTEM
1 OXYGEN CONTENT
45 SYSTEM TOO RICH OR LEAN
3 MAP SENSOR
48 PRIMARY HEATED 02 SENSOR
5 MAP SENSOR
54 CRANKSHAFT SPEED
6 CRANK ANGLE
61 PRIMARY 02 SENSOR CIRCUIT
7 THROTTLE ANGLE
63 SECONDARY 02 SENSOR CIRCUIT
8 TDC POSITION
67 CATALYST SYSTEM
9 No 1 CYLINDER POSITION
70 AUTOMATIC TRANSAXLE
12 EXHAUST GAS RECIRCULATION
71-74 RANDOM MISFIRE
23 KNOCK SENSOR
80 EXHAUST GAS RECIRCULATION
13 ATMOSPHERE PRESSURE
86 ENGINE COOLANT TEMP. CIRCUIT
14 ELECTRONIC AIR CONTROL
90 EVAPORATIVE EMISSION CONTROL SYSTEM LEAK DETECTED
15 IGNITION OUTPUT CONTROL
91 FUEL TANK PRESSURE CIRCUIT
16 FUEL INJECTOR
92 EVAPORATIVE EMISSION CONTROL SYSTEM INSUFFICIENT
17 VEHICLE SPEED SENSOR
41 02 SENSOR HEATER
20 ELECTRONIC LOAD DETECTOR
63 INTAKE AIR TEMP
