Just bought a used '03 PreRunner from my uncle. Quite a few miles on it but it runs like a dream.
The other day, I filled up with gas. Shortly after getting on the highway (~1 min after the fillup), I noticed the check engine light come on. Naturally, I figured I hadn't tightened the cap correctly. I took care of this, but the light stayed on. Consulting the manual tells me that this should reset after a few trips. So I continued on my merry way.
Now a week after this incident, I haven't noticed any issues. No funny noises, nothing. But the light is still there. Oil level is fine.
So, I'm ready to forget about the thing. But I figured I should probably check to see if everything is good in terms of oil pressure. Logic: if the oil is topped up fine, and the oil is flowing, then I don't think there is any immediate danger.
Long story short- can anyone advise me as to how I should go about checking the pressure?
Thanks a bundle!
