97 ford ranger, passed smog recently,slightly overdue for oil change but no noises/changes in the way it drives recently.check engine comes on a few days ago, I immediately borrow the OBDII reader from Autozone 15 miles away (had to call 4 before I found one that still lends one out for free w/deposit, BTW), it comes back with P1443 code, which Autozone says means about 8 different things. check engine light goes off after OBDII read even though I didn‘t press the button to remove the code from computer via reader. CE comes on again about 50 miles later, turns off again awhile laterwhat‘s the deal? according to multiple internet posts P1443 indicates an emissions control problem,usually the solenoidthere is some rust to the emissions system running the length of the truck but Meineike said recently it‘s superficial and fine for now. In any case, if the CE light doesn‘t keep coming on, should I worry about it? or pay to have someone take a closer look now?
My 97 Ranger check engine light came on/off randomly and scanned code P1443. I replaced the gas cap, evap. sensor and vacuum hoses. This did not fix problem. I then removed the vacuum hose from the purge solenoid valve and squirted two quick squirts of silicone lubricant into the vacuum port of the solenoid, while holding it in the upright position, replaced the vacuum hose and drove around the block. Check engine light went out and and never came back on. Sly
There are literally thousands of things that can cause a check engine light to come on. It could be anything from an EVAP leak to a transmission problem. Most repair facilities will check that at no charge. Advance Auto Parts and Auto Zone have generic diagnostic trouble code scanners that will pull codes and can point you in the right direction. It is my understanding that they also provide this service at no charge but you may want to call your local store to confirm that.
Read the small fine print on the side of the tire. It'll give proper tire psi.
