What this code means
P0757 may indicate that the control module is seeing a mismatch between the commanded state of shift solenoid valve B and the hydraulic response during low clutch engagement.
What the vehicle may do
- The vehicle may set a warning light.
- The vehicle may have shift-feel changes under certain operating conditions.
- The concern may be most noticeable when the affected clutch circuit is being applied.
Possible fault areas
- Possible shift solenoid valve B operation concern.
- Possible internal transmission hydraulic or mechanical concern.
- Possible shift valve B concern.
Diagnostic path
Open on what P0757 is looking for
On this 2020 to 2025 Honda CR-V 2.0 Hybrid, P0757 is for shift solenoid valve B stuck ON. In plain terms, the ICM is seeing a command-versus-response problem: during low clutch engagement, it can detect hydraulic pressure even though shift solenoid valve B is being commanded OFF. The vehicle may have shift-feel issues, may set the warning light, or may act differently under the conditions where that clutch is being applied. The broad fault areas here are possible solenoid operation, possible internal transmission hydraulic or mechanical concerns, and the remaining shift valve B path. Before you get into the specific P0757 checks, start with the basic troubleshooting approach, then work through the tests in order so you do not condemn the wrong part.
Set the vehicle up safely
Raise the vehicle on a lift, make sure it is securely supported, and make sure all four wheels can rotate freely. This test is done with the vehicle running on the lift, so keep the braking gentle. Do not brake hard during this check, because that can damage the driveline.
Reproduce the low clutch operating condition
Using the HDS Direct Input Clutch Test Assistances Mode, run the vehicle at a steady speed with the low clutch engaged for at least 10 seconds. After that, apply the brakes and slowly bring the wheels to a stop. The point here is to reproduce the operating condition where the ICM is watching the hydraulic response for this fault.
Command shift solenoid valve B
Next, turn the vehicle to ON mode. Run the HDS Shift Solenoid Test and test shift solenoid valve B. You are listening for intermittent operation sound during the ON and OFF command. If that inspection is abnormal, the diagnostic path points to a problem with shift solenoid valve B.
Check the fluid through a strainer
If the solenoid check does not settle it, drain the transmission fluid through a strainer. 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 diagnostic path points toward a transmission e-CVT problem.
Narrow the remaining path
If the other inspection items indicate a normal condition, the remaining fault path is shift valve B. At that point, pause, recheck the earlier diagnostic path, and avoid guessing. The logic is simple: prove solenoid operation, check for transmission material concerns, and only then narrow the problem to the remaining shift valve B path.
Close and verification reminder
Keep verification separate from the fault-isolation tests. After the diagnosed fault is corrected, verify the repair and confirm P0757 stays gone. Takeaway: this code is about commanded solenoid state versus hydraulic response, so work the path in order and let each inspection narrow the fault area.

Final check
P0757 is often approached as a command-versus-response transmission hydraulic diagnostic, so the test path should separate solenoid operation, transmission material concerns, and the remaining shift-a
