The 2-3 shift solenoid is a normally open exhaust valve that, in conjunction with the 1-2 shift solenoid, allows four different shifting combinations. The 2-3 shift solenoid is attached to the control valve body. The PCM controls the solenoid by providing a ground through circuit 1223.

DTC P0758 will set if the solenoid feedback does not match the PCM commanded state (e.g. PCM commanding solenoid ON and feedback reads ignition voltage) and the following conditions have been met:

DTC P0758 is a type A DTC.

An open in the ignition feed circuit to the trans solenoids will set multiple codes (P0753 and P1860).
