Q: P0720 and P1529 codes and speedometer is not working.

asked by on November 12, 2016

It has two codes showing. P0720 and P1529. My speedometer isn't working and I was working if I should drive it. I have an hour long trip to do and wondering if my car would even make it.

My car has 206000 miles.
My car has an automatic transmission.

Hi. The codes you have deal with a problem in the transmission. The P0720 code is for the output shaft sensor circuit having a fault. This means that the sensor is not reading what is supposed to properly and that can cause the odometer to go out or the transmission will have a delayed shift. The code you have is there because of the first code. This code requested that the engine light be turned on because of the transmission code. Before I took a hour long drive, I would get the output sensor replaced so there is no other damaged done to the transmission. I suggest you have a certified tech from YourMechanic come and replace your output shaft sensor.
