Hello everyone, This is my first post here. I own a 2007 Honda CR-V, and I’ve been experiencing an issue since I got my car back from the wash. The engine idles at a high RPM of around 1.5, and when I shift into drive, it drops to about 1.0 but fluctuates on its own. I haven't received any check engine light, but I ran an OBD scanner and found the following error codes: 14-1 Left front wheel speed sensor failure 18-1 Left rear wheel speed sensor failure 61-1 Battery voltage failure B1008 MICU lost communication with Gauge Control Module (A/T message) I replaced the alternator, thinking that water might have entered and caused it to fail, and I also cleaned the throttle body and MAF sensor. However, the RPM fluctuations persist. Any advice or insights would be greatly appreciated! I’ve attached a video url for reference.
