What this code means
P0752 may mean the control module is seeing a hydraulic response that does not match the commanded state of shift solenoid valve A.
What the vehicle may do
- The vehicle may have abnormal drive engagement or clutch engagement behavior.
- The transmission may behave differently during conditions involving high clutch engagement.
Possible fault areas
- A possible high-clutch related concern may be involved.
- Shift solenoid valve A operation can be involved.
- Transmission fluid contamination, metal debris, or clutch material may be involved.
- Shift valve A may be involved.
Diagnostic path
Open on the code logic
On this Accord Hybrid e-CVT, P0752 is a command-versus-response code for shift solenoid valve A. In plain terms, the ICM may be seeing hydraulic pressure when shift solenoid valve A is supposed to be OFF during high clutch engagement. The vehicle may have abnormal drive or clutch engagement behavior, and the possible fault areas can include a high-clutch related issue, shift solenoid valve A operation, internal transmission material or debris, or shift valve A. Start with the basic system checks and follow a structured diagnostic approach before getting into the specific tests.
Handle related high-clutch faults first
Before chasing P0752 by itself, look for any high-clutch related fault information. If that kind of fault is present, diagnose it first. That matters here because this code is judged during high clutch engagement, so you do not want to condemn the solenoid or valve path before the high-clutch side has been addressed.
Reproduce the clutch engagement condition safely
Next, raise the vehicle on a lift. Make sure it is securely supported and that all four wheels can rotate freely. Using the HDS Direct Input Clutch Test Assistances Mode, run the vehicle at a steady speed with the high clutch engaged for at least 10 seconds. Then apply the brakes and bring the wheels down to a stop slowly. Do not brake hard while the vehicle is running on the lift, because that can damage the driveline.
Check shift solenoid valve A operation
For the shift solenoid valve A inspection, turn the vehicle to the ON mode. Then run the HDS Shift Solenoid Test and test shift solenoid valve A. What you are listening for is intermittent operation sound at ON and OFF. If that inspection is abnormal, the diagnostic path identifies a problem with shift solenoid valve A.
Inspect the transmission fluid through a strainer
If the solenoid operation check does not point you straight to the solenoid, move to 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. If that inspection is abnormal, the problem is in the transmission e-CVT side of the diagnosis.
Isolate shift valve A if the earlier checks are normal
If the earlier inspection items are normal, the remaining diagnostic conclusion is shift valve A. At that point, the path has separated the electrical command check, the solenoid response check, and the internal debris check, leaving shift valve A as the fault area identified by this procedure.
Takeaway and CTA
The key on P0752 is to prove the mismatch between commanded solenoid state and hydraulic response, then work through the high-clutch context, solenoid operation, transmission debris inspection, and finally shift valve A without skipping ahead.

Final check
P0752 is often approached as a command-versus-response hydraulic diagnosis, not just as a simple solenoid code.
