Frequently Asked Questions
Q: What are symptoms of a bad battery current sensor?
A: Check engine light with battery/charging codes (P154A, P154B, P1554-P1557). Other symptoms: battery not charging properly, overnight battery drain, intermittent electrical issues, auto start-stop malfunction, inaccurate battery state-of-charge on dash.
Q: Does this fit my 2014 Honda CR-V?
A: Yes. Direct OEM-spec replacement for 2012-2016 CR-V (all trims). Also fits 2012-2015 Civic (all trims), 2013-2020 Acura ILX, and 2013-2018 Acura RDX. Verify original part number is 38920-TR0-A02.
Q: Will I need to reset or calibrate after installation?
A: Yes. Disconnect battery for 10 minutes after install, reconnect, start engine and idle 15 minutes with all accessories off. This allows ECM to relearn sensor parameters. Some models may need scan tool to clear battery management adaptation values.
Q: Is this plug-and-play?
A: Yes. Sensor mounts on battery negative terminal and connects to existing wiring harness with factory connector. No cutting, splicing, or modification. 10mm socket — 5-minute job for most DIYers.
