2002 Mazda MPV TSC Issue: O/D Off and Battery Light On with PO113 Code

Model: mazda mpv tsc Fault Code: P0420 Posted: 2011-04-21 16:42

I own a 2002 Mazda MPV with a persistent fault code PO113, along with the TSC (Traction Stability Control) light, O/D (Overdrive) off light, and battery warning light illuminated. The vehicle is showing multiple diagnostic indicators simultaneously. I'm seeking advice on possible causes and solutions for this combination of issues. Does anyone have experience with similar symptoms in a 2002 Mazda MPV? What could be causing the PO113 code along with these warning lights?
