Thoughts and comments requested. This is also on the "other" forum, I need the information.
Put a rebuilt 3VZE in my truck, or is it a car?, and immediately got hit with Code 52. It was still at the shop, so he replaced the Knock sensor wire, hoping that was the problem. Started it up, same code. opened it up, replaced the new knock sensor (that came on the rebuild) with the Original KS, and mounted it on the engine lift hook. Still have the code, but, the engine does not go into a "limp, or safe" mode.
Mechanic was perplexed, but he said it was running good, timing shows no malfunctions at highway speeds, so I took it out and have driven it 600 miles now with no perceivable problems.
My question is, why? I have an always on check engine light, no noticeable reduction in performance and while I didn't have 500 miles on it after I bought it before the head gasket meltdown, I actually don't have a lot of miles under my arse with this vehicle.
My second question is what is acceptable gas mileage with this beast? My third question is what can i do to possibly improve on the 14-16 MPG I presently enjoy(?)
BTW, I spoke with a former Toyota Service manager(we're related), who, after listening to the above, with slightly more detail, suggested a piece of black tape over the light.
