RE: '94 Accord "Check Engine" light
Thanks 2POINTaut0:
It appears that I have codes 41 (Primary Oxygen sensor, Heater Circuit malfunction) and 3 (MAP...Manifold Absolute Pressure defective circuit/sensor) set.
Any further ideas????
Thanks a bunch!

you can check the sensor heater circuit with an ohm meter, and this link;http://img139.imageshack.us/my.php?i...acode41no7.jpg
The map sensor code could be caused by a vacum leak or sticking EGR valve.
Worth the effort to reset it and try to determine the conditions that cause it to set

Pull the 7.5 amp radio (backup) fuse in the box in the engine bay for a minute. This will clear the ECU/TCU and also wipe out the stations programmed in the radio. Make sure that you have the code (I feel like I am writing the Haynes manual right now!)

I swear...why can't they tell you once in the first chapter and not bug you every time you disconnect the battery!

most likely the heater is shot in the o2 sensor. as far as code 3...that's tricky. if it's a hard failure(recodes directly after clearing the code and warming up the car) then it is easier to diagnose. see what happens.
