It's a code for the output speed sensor. Might just want to take a look at the wires and the sensor first.
that's my next plan is to scope the speed sensor readings, I just found a pdf manual so I can get the pinouts of the trans plug. The manual I found through the forum says its for a 2013, but it says the trans is a 6 speed auto, I'm thinking that manual is for a gen 2?It's the output speed sensor on the trans. As a mechanic you understand you have an input side and an output side on the trans and the ratio of the rpm of each one should be somewhere close to if you divide by the gear ratio in each gear so let's say gear X is 2 to 1 than the output speed is half of the input speed and gear Y is 1 to 1 than they should be the same or close to it minus the slip in the converter or clutches the trans sees.
It's a simple hall effect sensor. Hook up your scope on it and see the signal and amplitude and you can figure out if it is working or not.
Did you ever figure out this problem I have the same exact problemHey guys, I have a 2011 kia soul ! automatic, 194k miles, it has been a great little car, but yesterday it wouldn't shift out of 1st gear, when it finally did, it slammed into 2nd, and the check engine light came on. p0722 code came up with my scanner. Once it did shift, I was able to use gear 2 and 3 with the manual shift mode, but no 1st or 4th.
I am a seasoned mechanic, and I fix tractors for a living, What am I in for? The only video I've found seems to require removing the valve body from the trans.
