What this code means
P0752 may mean the control module is seeing hydraulic behavior that does not match the commanded state of shift solenoid valve A.
What the vehicle may do
- The vehicle may turn on a warning light.
- The vehicle may change drive behavior or feel abnormal during clutch engagement.
- The transmission may show possible pressure-control or engagement concerns.
Possible fault areas
- Shift solenoid valve A can be involved.
- The transmission hydraulic system can be involved.
- Shift valve A can be involved.
Diagnostic path
Opening context
On this 2020 to 2025 Honda CR-V 2.0 hybrid, P0752 means shift solenoid valve A is being treated as stuck on. In plain terms, the control module is commanding one thing and seeing a hydraulic response that does not match. The vehicle may turn on a warning light, may change how it drives, or may show clutch engagement and pressure-control behavior that does not feel normal. The possible fault areas can include shift solenoid valve A, the hydraulic side of the transmission, or shift valve A. Before getting into the code-specific checks, start with the basic system checks and follow a structured diagnostic approach.
Reproduce the clutch engagement conditions
Start by raising the vehicle on a lift. Make sure it is securely supported, and make sure all four wheels can rotate freely. From there, use the HDS Direct Input Clutch Test Assistances Mode and run the test-drive sequence in order. First, run the vehicle at a steady speed with the low clutch engaged for at least 10 seconds. Then run it at a steady speed with the high clutch engaged for at least 10 seconds. After that, apply the brakes and slowly bring the wheels to a stop. Do not brake hard while the vehicle is running on the lift, because that can damage the driveline.
Check shift solenoid valve A operation
Next, turn the vehicle to the ON mode. Use the HDS Shift Solenoid Test and command shift solenoid valve A. You are listening for intermittent operation sound as the solenoid is switched on and off. If that inspection is abnormal, the problem points to shift solenoid valve A.
Inspect the transmission fluid findings
If the solenoid operation check does not identify the fault, move into the transmission inspection. Drain the transmission fluid through a strainer, then inspect the strainer for metal debris or excessive clutch material. The expected result is no metal debris and no excessive clutch material in the strainer. If that inspection is abnormal, the problem points to the transmission e-CVT.
Final fault direction and verification
If the other inspection items are normal, the remaining fault direction is shift valve A. Keep verification separate from the testing path: after the diagnostic work is complete, verify the repair and confirm the code stays gone. The key takeaway is that P0752 is a command-versus-hydraulic-response diagnosis: reproduce the clutch engagement conditions, check solenoid A operation, inspect the fluid findings, and only then narrow it to the hydraulic valve direction.

Final check
P0752 is often approached as a command-versus-response hydraulic diagnosis, using the scan tool command tests and fluid findings to narrow the fault direction.
