What does these code mean u3900 p0705 p0715 p1529

SOURCE: Sudden hesatation, loss of power, 2002 Hyundai Elantra

P0715 is the imput speed sensor is open or shorted. The P1529 is the transmission control module(computer) requsting the check engine light to turn on. These sensors are prone to going bad.

SOURCE: My car's check engine codes are p1723, p0740,

All of the codes are related to the transmission. Some indicate the input speed sensor. I'd bring it back to the transmission shop and tell them to deal with it. I don't know what your car was doing before you had the transmission replaced so it's hard to tell whether the repair was needed but since it was done, the problem should be the transmission shops, not yours. Best of luck and please post back, would love to hear how you make out. Greg

P1529 and P0720 does not seem to be understood.

P0715 means Input/Turbine Speed Sensor Circuit Malfunction.

P0118 means Engine Coolant Temperature Circuit High Input.
