A/T check light blinks 16 times?

[Ohhkevingee]

I did the self diagnostic test and no error codes were detected for all 10 flashes, but the two problems that keep happening is my MPH gauge just gives out and stops reading my speed and my steering wheel locks up as if the power steering gave out. (Fluid is good and power steering pump) It becomes hard to steer; this only happens once the mph gauge gives out. If the mph is being read then my steering is perfectly fine. So they happen simultaneously just a few minutes apart. I can't figure out why it does this, does anyone know how I can fix this? Has anyone came across this issue?

Have you checked the wiring for the transmission. Double check the connector for the speed sensor. Although the ECU does have a code for the speed sensor which is code 14 i believe.

Your speed sensor is probably bad or the connector has some corrosion in it. I would try taking the connector off, cleaning it, putting some dielectric grease in and reseating it and see what happens. If that doesn't fix it, you might need a new speed sensor. The ECU uses the speed sensor to reduce the power steering when you are at higher speeds to firm up the steering feel. So the ecu probably thinks you're going way faster than you are and locks up the steering.

I finally got around to doing the labor, it was actually damaged bad so I replaced it with a new one. It works perfectly fine now. Thanks for that one!
