1jz map sensor issues

[vagazzlesammystraya 0]

Hey guys.

Just got the next engine running in my mx83.thriwing up fault code for map sensor. Changed map sensor to a mates out of his soarer and still doing the same thing. Where next from here? Turns over and idles, but once you rev it it revs then won't idle and dies. Suggestions on what to do next?

I think this is about the 3rd thread about map issues in the past month.

4drsupra was talking about beating his with a hammer or something........

You might want to find his thread, or the one he hijacked, and see what other people were telling him to do.

I suggested testing it, like I do the HKS map sensors, but seems like all people can handle is changing it, and from what I seen didn't fix a fucking thing.

So I'm making an uneducated guess here, since I would never own a 1JZ in the first place, by saying it's a messed up wiring job ??

I tested the power and has 5v which it should, also has good earth. Only one I haven't tested yet because multimeter cooked it's shit, was the map signal wire. So I'll test that tomorrow. It's a complete jzx81 loom and ecu in my mx83 so no wiring has been cut and Joined from what I see. But hopefully it's a broken signal wire and I can hard wire a new one.

You will also need a hand vacuum/pressure pump.

does the earth go away when you unplug the ecu?

Haven't tested it yet. I'm about to get back onto it shortly and nut it out. Hopefully it's wiring from being pulled out a couple of times because I can fix that. But knowing my luck it'll be the ecu

Problem solved.

 

This would probably be Why. Used to have a fcd in it. Pulled the wire out while removing loom.

 

I'll happily except any abuse regarding my dumbness
