Hello. Too many issues. I recently bought a Montero Limited 2004 with 98000 miles. After few miles I got service light with codes p0431 and p0134 and right after 2 days p0171. Also, the tyre pressure light is blinking (tyres have 30 psi. I did try with 35 and nothing) and the active skid control system operation indicator and active skid control system off indicator lights up both and remain every time after I drive the Montero fo about 20 minutes. I wonder if I have an electrical problem or just lack of maintenance. I am moving to Texas and will need to pass the car inspection. Thank you for the help.
