Well, I woke up today and my check engine light was on. So I started my car and it started right up with no issues. That is until I started to drive it. A few seconds after I left my home the car stalled for a few seconds before coming back to life and driving like normal. So I drove it around for about 30 minutes and there were no issues. So I parked my car again, started it up let it run for about 10 minutes there were no issues, but I back out of the drive way again and I put it in drive and sure enough it stalls again but only for a few seconds then, it goes right back to normal. I have no clue what is causing this, but I have a business trip coming up in a few weeks and I don't have the money to put my car in the shop with these crazy times. I need to first try to fix it on my own. Thanks in advance everyone.

Hi,

What needs done first is to have the computer scanned to see why the light is on. That should point us in the right direction.

Since you want to do this yourself, see if there is a local parts store that will scan the computer for you. Most do it free of charge. Do that and let me know what codes were found so I can direct you.

Take care,
Joe

Hi,

The input speed sensor is near the starter motor. If you look at pic 1, I circled the sensor and have an arrow pointing where the starter would be located.

JACOBANDNICKOLAS thank you so much. I have to ask one more question. Is it possible that my transmission is bad as well? Or will the provided information you sent for sure correct the issue?

Hi,

Anything is possible. It could be the sensor, wiring, connector, TCM, and so on. Here is my concern: The vehicle came with a 5 year 60,000 mile power-train warranty, so if it is the transmission, it should be covered by the manufacturer's warranty. If you do something wrong, they may void the warranty. What I would recommend is to contact a dealer with your VIN number and confirm it is still under warranty. I don't actually know the in service date, but you are good as far as mileage.

The only way I can confirm would be to have you complete diagnostics. I will provide the directions. I noted you indicated no knowledge, so you may not feel comfortable doing this or have the tooling. Regardless, I want you to have them.
