Circuit Description
WARNING: This page is about a different car, the 2004 Pontiac Sunfire and 2004 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
The 2-3 shift solenoid (SS) valve is a normally-open exhaust valve that, in conjunction with the 1-2 shift solenoid (SS) valve, allows 4 different shifting combinations. Refer to Shift Solenoid Valve State and Gear Ratio . The 2-3 SS valve is attached to the control valve body, within the transmission.
The solenoid receives ignition voltage through the fused power feed circuit. The PCM commands the solenoid ON or OFF by providing a ground path.
When the PCM detects a continuous open, short to ground, or short to voltage in the 2-3 SS valve circuit, then DTC P0758 sets. DTC P0758 is a type A DTC.
