tres bon thread

No love for the 4 doors? Or is it compatible with engines too, so my LX has the same as the 97 DX coupe since we have the same engine?

should make this a sticky.

Update Ecu And Abs Codes Here

---------------------------------How to check your CEL code----------------------------------
On the passenger side of your car, under the dash beneath the glove box, you will find a green cover above the kickpanel that houses a blue connector that has two wires.

All that you need to do is turn the ignition off, and using the piece of wire or paperclip, jump the blue connector so that you connect the two wires together. Basically stick one end of the paperclip or peice of wire into one prong on the connector and stick the other end of the paperclip or wire into the other prong.

Once you have done this, turn the key to the IGN position and watch your CEL light. It will illuminate in a series of flashes.

You will notice that there will be LONG flashes and SHORT flashes. All of the ECU trouble codes are two-digits. LONG flashes determine the TENS digit by the number of times it flashes, and SHORT flashes determine the ONES digit by the number of times it flashes.

ie. LONG-LONG-LONG-SHORT-SHORT-SHORT-SHORT-PAUSE

is the trouble code: 34

3 LONG flashes followed by 4 short flashes, then a long pause. If that is the only code the ECU is throwing, then the code will simply repeat until you remove the key. If, however there are more than one ECU error code, then you will see a different series of flashes followed by the long pause. Once all the ECU codes have been displayed, they will continuously cycle until you remove the key.

ie. LONG-LONG-SHORT-PAUSE-LONG-LONG-LONG-LONG-SHORT-SHORT-SHORT-PAUSE

is the trouble code: 21 and 43

If your car is 1996 or newer, you can plug in an OBD-2 code reader. It displays a letter followed by a 4-digit number. Each flashing-light code is covered by a couple OBD-2 codes, so they're a little more specific. For example 63 (2nd O2 sensor) might be P0137 (low voltage), P0138 (high voltage), or P0139 (slow response).

Now that your peptalk is over here you go...



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

8 TDC - top dead centre sensor
9 CYP - cylinder sensor
10 IAT - intake air temperature sensor
12 EGR - exhaust gas recirculation lift valve

19 Automatic transmission lockup control valve
20 Electrical load detector
21 VTEC spool solenoid valve
22 VTEC pressure valve
