Yes, The hybrid battery is in great cond. I have had this car to one independent shop and a Honda shop. No help from either one. I have pulled the Hybrid battery again to recheck voltage and they read 15.17, 15.13, 15.17, 15.15, 15.17, 15.16, 15.20, 15.17, 15.17
12 volt is in very good cond. clean and tight. Any electrical connection that I have ever pulled apart on this car have always been clean.
No other codes. Honda did a reflash.
Any suggestions are welcome

 

What year Hybrid?

 

Also important - what driveability issue are you having?

 

2005 Accord hybrid, no other issues. Fuel mileage good, does not seem to use assist as much as it did when new but that could be a decade of a fuzzy memory. After reflash, the auto-stop started working again which had not worked for a long time.
Thanks, Greg.

 

For a 2005 Accord Hybrid, the P0AC4 code is an information code only.

The P0A7F is High Voltage (HV) Battery Capacity Serious Deterioration. If the usable battery capacity lowers to a specified value (threshold), the battery condition monitor module detects a malfunction and stores a DTC. Usable battery capacity range of the battery module is calculated from the battery capacity (ΔAh) and SOC (state of charge) change width (ΔSOC) of a specified section.

Batteries generally have a limited lifespan, and their capacity and performance will diminish.

Most likely to get rid of the code means getting a new or reconditioned replacement. Otherwise, if no replacement, you'll probably have to live with it or sell it.

 

Got a reconditioned battery. Yes, you are correct, the condition of the battery was the cause.
