97 Ford Ranger Dome light and check engine light question

did you do a computer/OBD check? mine came on, and the computer said it was a house malfunction. gonna check it in the morning. I have a 98 ranger.

also, the sensor in the door on mine is bad, leaving the dome light on sometimes. this is affected by changing temps, happens more in the fall. check to see if it is your door sensor.

for the dome lite, shoot some WD -40 in the door, it will fix it for 6 months or so. this fixed mine.

ok, where do i shoot the wd-40?

thanks

i shot it in by the door handle,

You would be better off using some type of degreaser (I used carb cleaner) and spray it into the latch mechanism. If your truck is under warranty have them replace the door interlock switch. You can buy the switch and replace it yourself. It is part of the door latch mechanism and reportedly is available for about $10. I got mine under warranty.

When my engine light came on it was the oxygen sensor.

when my engine light came on, it ended up being the DTPE hoses had corroded. i replaced them this weekend, and it cleared everything up, including the hellacious knocking it was doing. the OBD reader really made it quick work.
