You need an OBDII scan tool to read the codes on a 7th gen Civic (01-05). If you have a 6th gen Civic (96-00), then click the CEL link in my signature.

Many thanks for the super quick reply. Have just found the plug, run the test and got the following fault codes back:

17 speed sensor (sounds right because the speedo stopped working when the CEL came on)
41 primary oxygen sensor heater
65 secondary oxygen sensor heater wire (black wire)
92 EVAP Solenoid/Valve/Vacuum Lines

I'm a bit puzzled about the link to all these different faults when it was just the speedo not working. The alternator sensor fuse also keeps blowing so I don't know how to start fixing this lot
Thanks again
Chris

Thanks for your help RonJ. I have checked the Fuse 15 TSB and can find no chafing of the wiring around connector C115 - in fact my connector ends in a blanking plug and there is no continuation of the loom.

However, after checking around all the plugs/sockets on the loom in the engine compartment and resetting the ECU, the speedo started working again and the CEL went out (obviously) - but on a test drive, the speedo once again packed up, CEL came on and fuse 15 blew again. Checked CEL codes again and still gettiing:

41 Primary Oxygen Sensor Heater
65 Secondary Oxygen Sensor Heater Wire
92 EVAP sensor/valve/vacuum line

If there really is a problem with the above components - how come I could fix the speedo just by unplugging/ plugging the loom connectors?

Would it be more beneficial to just get the car on a proper scanner - will this give me more information on what really is the fault?

Any help appreciated.
Cheers
Chris
