Question
I would like to know what trouble codes 27, 37, and 43 are.

Thank You

Answer
Hi Ryan,
27 means that the injector output driver circuit is not responding properly to the control signal
37 means that the torque converter lock-up control solenoid is not responding to the control
   signal being sent to it at around 40 mph
43 means that the primary winding of the spark coil is not responding properly to the control
   circuit signal being sent to it.
