Yesterday morning the check engine light turned on in my 1997 Nissan Maxima, 127K miles, manual transmission. The mechanic pulled a speed sensor code but it's testing within range now. I was planning to go on a 2-3 hour drive tomorrow. If the sensor fails, what would the typical symptoms be?
I had a failing speed sensor on a truck and the main symptom was the ABS system kicking on between 3-4 mph when I would come to a stop. It was consistent until I fixed it. However, it did not throw a check engine light.
