Corrections:

From about 0.1V to about 4.5V.

Set the multimeter to 5V DC for the variable wire. Any higher and you won't
be able to see the needle's movement.

(I really should proofread better before I post...)

Re: throttle position sensor 1990 Civic - junkyard part?
 

Hi all,

Thanks for the responses. Yes, it is a code 7. I read elsewhere on the
group that this code is generally reliable.

The problem has been over the last couple months, with the code set
last week. I presume this would explain the bogging, dropping revs and
seeming to konk out. It especially happens (when it does) when I'm at
whatever speed I want, and then let off the gas. The problem is
intermittent but does seem to be getting generally worse.

I guess I'll tackle this next weekend then. Should I expect weird
failures like this going forward?

THanks,
Derek

the sensor has a carbon track that wears in the place where you most
commonly put the throttle while driving. if you disassemble the sensor,
you can see it. easiest solution is to replace the whole sensor. you
can "repair" the sensor by splaying the brush so it contacts a wider
track inside, but it's a lot of effort.

bottom line, replace and enjoy. symptoms are exactly as you describe.
once replaced, you'll be back to normal like nothing ever happened.

I suggest trying a electronic contact cleaner/lube spray.(lightly)
The TPS is nothing more than a potentiometer.

having done it both ways, i say doing it on the vehicle without removing
the throttle body [dpfi] /is/ the easiest way. use a chisel to start
the shear bolts rotating, and robert's your mother's brother.
