Sajeev,

Tonight, while driving on the interstate, the tire pressure warning light came on in my ’15 Honda Fit, then the ESC light came on, then the power steering warning light came on, and then the info display said to check the charging system. Everything seemed to be working just fine, though. I pulled off to check the serpentine belt, which was intact so I started searching on the internet for the symptoms.

According to the forums, it’s sort of a known problem that’s due to glitches in the electrical system causing erroneous fault codes. Dealers usually try replacing the alternator, which doesn’t help.

I’ll check all the connections in the morning, but in the meantime I’m leaning towards a faulty ABS sensor, since those are used for the TPMS in my car, not an actual pressure transducer, and the first light that goes on is for tire pressure. Also, the check charging system warning was intermittent.
