Q: Check Engine Light is on the code is coming as p0740

asked by on

Check engine light is on, coming up with code p0740.

My car has 112000 miles.
My car has an automatic transmission.

The DTC P0740 is for a "Problem in Lock-up Control System". This code means that there is most likely a problem within the transmission. It could also possibly be caused by a wiring issue or a control module. It would be best to have a certified mechanic take a look at the vehicle in person and perform necessary diagnostics on the code to determine exactly what should be done.
