    I'm hoping this isn't the start of an avalanche of problems...I just got the fan clutch repaired and now the Service Engine Soon light came on again tonight on the way home from the store. This time no reading on the engine temp gauge. It's "off-scale low" or below 100 degrees.

    I'll take it to the AutoZone tomorrow and have them plug in the doohicky to tell me the code, but was curious if anyone had a "quick solution". I scoured some other sites and nothing was showing up for this issue I could find.

    I did check the fuses, and none look blown.
