Hey, I was replacing my head gasket and timing chain and in the process snapped a wire off the main wire harness and can't figure out where it goes or where the other section of wire went. It's on the main wire harness and is situated between the fuel filter and the oil filter below the EFI unit. Check the pics......Does this need to be reconnected??

Location in the engine compartment

 

id be more worried about that crappy fram oil filter

 

I think it might be the wire that goes to the oil pressure sending unit, should be a sensor right around the oil filter somehwere.

 

Maybe to knock sensor, which is just to left (toward back) of oil filter. Oil press sender is below oil filter.

 

Dump the fram

 

What kind of oil filter should be used?

 

That's the kind of question that opens the proverbial can of debate worms. You'll get a lot of opinions on that matter. A quick YT search will give you some clue.

Toyota, WIX, Amsoil, Mobil1, and more. I use WIX. They're reputably good, quality filters with the anti-drainback valve. And, they're relatively inexpensive and doesn't require a trip to the dealership.

Hard for me to tell from the pic what the wire is. A broader view would help to exactify.

 

TOYOTA FACTORY OIL FILTERS ONLY! There are many reasons. And there black and say Toyota on them Thought I would get the ball rolling on the subject.

 

(What'd I tell you?........)

Back to the topic of the original question...That would be the knock sensor. Kinda need that.
