Why is my ECU fault code not disabled?

Sensor voltage is going to 0V as part of normal operation but low voltage fault detection is not disabled (Error Low). The voltage at the analog input pin has been below the Error Low voltage for longer than one second. Sensor may be faulty. Volt channel sensor disconnected. Error Low setting incorrect.

When to use the p0966 transmission solenoid code?

Code P0966 is set by the PCM when it detects that the pressure control solenoid “B” control circuit is experiencing a low voltage condition and therefore is not functioning properly. Example of transmission solenoids:

What causes the p0079 OBD-II trouble code?

P0079 indicates an issue that is found when the Engine Control Module (ECM) tries to control the Bank 1 exhaust valve solenoid and finds the system readings to be out of range. Specifically, this code is found when the ECM detects low system voltage. This code is similar to P0078 and P0080. What causes the P0079 code?
