before replacing the solenoid ck this out....

When the PCM detects a continuous open, short to ground or short to voltage in the PC solenoid valve circuit, then DTC P0748 sets. DTC P0748 is a type C DTC.
PC - pressure control solenoid .
The powertrain control module (PCM) uses the pressure control (PC) solenoid valve in order to regulate the transmission line pressure. The PC solenoid valve consists of an electrical connector, a coil, an armature, a regulating spring, and a poppet valve. The PC solenoid valve is attached to the control valve body. The PCM compares TP voltage, fluid temperature, gear states, and other inputs in order to determine the line pressure appropriate for a given load. The PCM regulates the pressure by applying a varying amperage to the PC solenoid valve. The applied amperage varies from 0.1 amps for maximum line pressure to 1.1 amps for minimum line pressure. The PCM then monitors the amperage at the return line.
C0561
System Disabled Information Stored
EBCM
DTC C0561 in Antilock Brake System This code is a result of the transmission code .
The electronic brake control module (EBCM) disables the traction control when other electronic control modules set DTCs for components that effect the operation of the traction control system.

P0031 and P0051 02 heater control, P0131, P0151 and P0132 02 voltage P0748 pressure control solenoid a electric. Your 02 sensors not problem, problem is electric in nature

1 You have a bad O2 sensor.
2 I think this second one may mean Possible causes
- Low transmission fluid level
- Dirty transmission fluid
- Faulty Pressure Control Solenoid
- Pressure Control Solenoid harness is open or shorted
- Pressure Control Solenoid circuit poor electrical connection

Hi.............P0748 being a pressure control solinoid ,elecrical, to me a means that there is an electical problem in the solinoid circuit or the solinoid it self maybe burnt out. The pressure control solinoid is in the trans.On chrysler the solinoids are duty-cycle and controlled by the P.C.M. power train control module which is the same as E.C.M. . A test has to be performed to determine the problem. .

The code P0748 means "Pressure Control Solenoid "A" Electrical.
The GM Diagnostic Scanner can work on your car.

Symptom:

P-0748 GOV PRESSURE SOL CONTROL/TRANS RELAY CIRCUITS

When Monitored and Set Condition:

P-0748 GOV PRESSURE SOL CONTROL/TRANS RELAY CIRCUITS

When Monitored: Continuously with the key on.

Set Condition: This code is set if the voltage detected on the Governor Pressure Solenoid

Control Circuit at the PCM is different than the expected voltage for 4.8 seconds.

POSSIBLE CAUSES

NO POSSIBLE CAUSES REMAINING

FUSED B(+) CIRCUIT OPEN

SOLENOID AND HARNESS ASSEMBLY DEFECTIVE

GOVERNOR PRESSURE SOLENOID DEFECTIVE

TRANSMISSION CONTROL RELAY DEFECTIVE

Hope helps.

One question? Did you clear the codes out of the system with a scanner? I believe that's the only way to do it now,unlike the old days when you could rest by disconnecting the battery. Hope this helps.
