What does trouble code P0748 mean?
Pressure Control Solenoid
When the code P0748 is set in the Powertrain Computer, it means that the Powertrain Computer or PCM is not seeing the specified electrical voltage drops from the Pressure Control Solenoid as it performs its tasks. Driving with this trouble code is not recommended.
What controls the pressure control solenoid?
Based on the signals coming from associated devices that monitor the vehicle’s speed, the PCM controls the pressure solenoids to direct fluids at the appropriate pressure, to various hydraulic circuits that change transmission gear ratio at the right time.
What does the p0748 code on a car mean?
What the P0748 code means. The pressure control solenoid manages transmission line pressure by monitoring various driving conditions such as speed, engine load, and throttle position. It sends messages to the vehicle’s computer in order to facilitate the appropriate pressure for those specific conditions.
When to use the p0778 code on a solenoid?
The code P0778 is set by the PCM when the Pressure Control Solenoid “B” is experiencing an electrical malfunction. Example of a transmission pressure control solenoid:
When does the PCM set the code p0778?
The code P0778 is set by the PCM when the Pressure Control Solenoid “B” is experiencing an electrical malfunction. Example of a transmission pressure control solenoid: What is the severity of this DTC?
What is the DTC code for pressure control solenoid electrical?
Cost of diagnosing the P0748 code. P0748 is a diagnostic trouble code (DTC) for “Pressure Control Solenoid Electrical”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
