P0748 2013 Toyota RAV4 Code - Pressure Control Solenoid 'A' Electrical
Quick Answer
Changing from 1st to 6th is performed by the Engine Control Module (ECM) turning shift solenoid valves SL1, SL2, SL3, SL4, and SL on and off. Common causes include Low transmission fluid level, Dirty transmission fluid, Faulty Pressure Control Solenoid 'A' valve (Shift Solenoid Valve SL1). Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0748 2013 Toyota RAV4 Description
This Diagnostic Trouble Code (DTC) indicates an open or short in the shift solenoid valve SL1 circuit. The ECM commands gear shifts by turning the shift solenoid valves on or off. When there is an open or short circuit in any shift solenoid valve circuit, the ECM detects the problem and illuminates the MIL, and stores the DTC. The ECM also performs the fail-safe function and turns the other normal shift solenoid valves on or off. (In case of an open or short circuit, the ECM stops sending current to the circuit.)
While driving and shifting between the 4th and 5th gears, if the ECM detects an open or short in the shift solenoid valve SL1 circuit, the ECM determines there is a malfunction.
What are the Possible Causes of the DTC P0748 2013 Toyota RAV4?
- Low transmission fluid level
- Dirty transmission fluid
- Faulty Pressure Control Solenoid 'A' valve (Shift Solenoid Valve SL1)
- Pressure Control Solenoid 'A' valve harness is open or shorted
- Pressure Control Solenoid 'A' valve circuit poor electrical connection
- Faulty Engine Control Module (ECM)
How to Fix the DTC P0748 2013 Toyota RAV4?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
