Hi everyone I know that when the low tire pressure light on the dash means that our tires are low. They are 14's and need 30lbs of tire pressure. My son filled them up and put them on 33lbs and then the light was blinking. Then he let out the extra pressure and they are all at 30lbs yet it is still blinking. Does this mean the sensor is bad? If so where is the best place to buy the sensor and where is it located to change it? Is this a Do It Yourself kind of job? Are there any YouTube videos anyone would recommend watching to switch it out? Thank you in advance if i don't have the opportunity to thank you later. Have an awesome day on purpose!
