Hello y’all, hoping for some advice with how to proceed. Just bought my Insight a week ago from a dealership and yesterday the IMA light and Check engine lights come on while I’m driving. 15 minutes later the IMA light flicks off and now only the engine light. The hybrid battery stopped working but the car runs fine on just the motor. I scanned the code with a app thing I have and it gave a P1448 code. The app also identifies the problem as being the ‘catalyst temperature sensor’. I did a little research and it seems that the problem is either with the battery fan dysfunctioning causing overheating. I’m no mechanic but I'm not a ninconpoop either. as I’m strapped for cash I hope to fix this myself . For the time being I plan on shutting off the hybrid battery and just using the motor temporarily until I can fix it. Can I shut off the hybrid battery completely and still drive the car without causing potential damage? Are there any other measures I need to take to avoid causing more damage or discharging the hybrid battery? Any advice on how to properly diagnose what’s going wrong would also be greatly appreciated.
