Wondering why my VTM-4 light comes on and why 4WD won’t engage. I have a 2005 Honda Pilot EX-L 4WD. I have no TPMS sensors on the tires so my tpms light and “flat tire” light is constantly on, I also have a check engine light for a o2 sensor (that i replaced 8 months ago so not sure if it’s bad or if it’s the fact that i might have a bad catalytic converter) I’m basically wondering if any of those issues with my car might be throwing my VTM-4 light on. Recently went camping got into a situation where i needed to use 4WD and it wouldn’t engage despite doing everything correctly, so I can’t tell if those other issues are disengaging my 4WD or if my 4WD is screwed. Would appreciate feedback thanks.
