Arrow Sulfur Penetrating Cabin

Guys

Well, I've got a litany of issues here all interlaced with one another but here it goes. Yesterday my friend and I were out and about when the cabin just filled with the smell of sulfur and continued to do so anytime the D90 was running. Now this has happened before but not at this concentration nor did it last very long. I'm thinking itís the response of the catalytic converter to the sulfur in the gas, which means the D90 is probably running too rich. In any case I can only surmise that itís running rich because an O2 sensor has cashed in. However, I can't check the ECU so see if it's thrown a code because the batteries are dead thanks to the alternator taking a nose dive. Typical. Just when I need the D90 it takes a vacation. Anyway, I wanted to post this to see if anyone has any other avenues of troubleshooting that I might take before I go out and replace the sensors.

Any and all advice greatly appreciated in advance! Thanks guys.

DJ

PS I did perform a search on O2 sensors, but most of the content was about replacing and purchasing and not diagnosing.

Defenders use the titania type sensor as opposed to the more common zirconia. But either way I believe you are looking for a voltage of around .5 volts, maybe less if NAS defenders run rich like I've been told they are.

DJ,
If the alternator is not working and you are running on the batteries only, I would fix that first. If you are feeding the system insufficient voltage, it will not correctly adjust the fuelling and it will default rich. i had a customer drive halfway across country in a classic a few years ago. He had a dead alternator and was running on batteries and switching them out...it overfuelled so much for so long that the rear carpets melted from the excess exhaust system heat. I'd fix the alternator and check the lambda sensor voltage. It should average .5v but be oscillating from about .1 to .9v.

Great! Thanks guys. I'm going to charge the batteries tonight before I yank the alternator out to have it bench tested. Hopefully the running rich issue is the result of the alternators malfunction. Thanks again, I'll let you guys know how it turns out.
