My '98 has been sitting for a couple of years and after making some repairs and driving it around for a couple of days, the Engine Malfunction light lit up. I copied the three number sets down several times to verify that I was not making any mistakes, then turned the key back a repeated the whole procedure, but two of them do not seem to correspond to anything, according to this page: http://vbxmaxima.8m.com/ecudecoder.html.

28 41 49

I plugged the intake sensor back in and I reset the light, so at least the 41 error code should be taken care of when I turn it on tomorrow. What do the 28 and 49 mean?

0409 right bank oxygen sensor

Thank you very much. Your response was helpful.

After fixing the previous problems and putting a couple hundred miles on the odometer, the light turned on again! I can't find what these mean, even using the search engine you provided.

Try entering 0705 and 0309 into the seach engine.
Evap codes, both of them.

75 = 0705 = P0440
Evaporative Emission (EVAP) Control System (Small Leak) (Negative Pressure)
Note: If both P0440 and P1448 are displayed, perform TROUBLE DIAGNOSIS FOR DTC P1448 first.

39 = 0309 = P1448
Evaporative Emission (EVAP) Canister Vent Control Valve (Open)

Go here and download the EC section of the service manual.
