DTC P0747: A/T Clutch Pressure Control Solenoid Valve A Stuck ON
WARNING: This page is about a different variant/trim than selected.
NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION ).
- If DTC P0747 is stored in the PCM, the transmission does not shift to any gear other than 2nd or 5th gear because of the fail-safe function.
- Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
- Clear the DTC with the HDS.
- Check the 5th Pressure Switch signal with the HDS in the A/T Data List.
Is the 5th Pressure Switch ON?
YES - Replace transmission fluid pressure switch D (5th clutch) (see TRANSMISSION FLUID PRESSURE SWITCH D (5TH CLUTCH) REPLACEMENT ).
NO - Go to step 4.
- Warm up the engine to normal operating temperature (the radiator fan comes on).
- Make sure that the transmission is filled to the proper level, and check for fluid leaks.
- Drain the ATF (see ATF REPLACEMENT
) through a strainer. Inspect the strainer for metal debris or excessive clutch material.
Does the strainer have metal debris or excessive clutch material?
YES - Replace the transmission.
NO - Replace the ATF (see ATF REPLACEMENT ), then go to step 7.
- Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
- Start the engine.
- With the brake pedal pressed, shift to D, and check the 2nd Pressure Switch signal with the HDS in the A/T Data List.
Does the 2nd Pressure Switch turn on with a shock caused by engaging gears?
YES - Faulty A/T clutch pressure control solenoid valve A. Replace the secondary valve body (A/T clutch pressure control solenoid valve A) (see SECONDARY VALVE BODY REPLACEMENT ).
NO - Intermittent failure, the system is OK at this time.
