Diagnostic connector location on a '94 Civic
The "Check Engine" light came on in my daughters 94 Civic the other day.
According to the Haynes manual this is still one of the old style systems where you retrieve a "flashcode" by jumpering the diagnostic connector. The picture in the book is no help at all. I have found the ECM located in the kick panel on the passenger side, but I can't find the connector to insert the jumper into. Can anyone here help me out? Thank you in advance. - Gary |
Re: Diagnostic connector location on a '94 Civic
You are oh so very close. Within an inch or so from the top, rear corner
of the ECM you will see a wire harness coming down from above. Two small bundles of wires in this wire harness are tucked back up (and I believe taped to the wire harness, it has been so long since I first pulled them down, I don't remember). You can pull these down. Both of them have blue connectors at the end and both of them have a piece of green tape around the wires just before the connector. One connector has 2 position, the other 3. The one you want is the one with 2 positions. If you still can't find it give me your e-mail address and I'll shoot you a photo.

There are two connectors there, a 3-wire and a 2-wire. You are supposed to short the 2-wire connector, then turn on the ignition (not the engine) and count the number of flashes. Bye, Leon |

Re: Diagnostic connector location on a '94 Civic
Many Thanks to both Randolph and Leon for their help. I located the
connector and retrieved a Code 41, The O2 sensor heater. Resistance through the heater in the sensor seems to be within acceptable range, about 16 ohms, and I measure a little over 12 volts available to the circuit through the harness. I sprayed the connectors with WD40 before I put them back together. I disconnected the battery to clear the code, but when I restarted the engine, The light came back on again. At this point I'm thinking I should just go ahead and replace the O2 sensor. Thanks again to all who replied. - Gary |
