P074B Severity
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
The Transmission is responsible for converting the power produced by the engine to movement of the vehicle. The transmission has its own control module (TCM). The TCM uses solenoids to control the fluid pressure that activates the different gears inside the transmission. If the TCM detects that the transmission is not going into third gear, it will set code P074B.
