On my 2012 Dodge Caravan the check engine light came on. I found it was a UO141 code and cleared it, the next morning it is back on again. cleared it again, drove it, stopped and started it several times and no code until morning and it is back again, Three times I have cleared it only to have it come back in the morning. It will not pass inspection because the codes have not been gone for a long enough time. Just wondering how to permentaly fix this.
