Odo or sensor? - Honda Prelude Forum

junkytri · 06-21-2003, 09:22 PM

okay, i start the car, i put it into first gear and drive..
blahblahlblah
i wanted to drag race some dumb white kid that's a ricer wannabe in a dumb semi tricked out neon
i floored it and as soon as the tach hits 4k, it flies to 8k in a blink of an eye and cuts off fuel injection cause of fuel injection cutoff in redline.
Okay, i know for a fact that my engine is not that powerful to push that meter up that high that fast.
Is this a sensor problem or tachometer problem and how could i fix this?

the topic should've been tach or sensor, sorry

clutch went out perhaps?

junkytri · 06-21-2003, 10:09 PM

it's not the clutch because i can still drive the car and the clutch works fine cause it's not that old
i know an engine cutoff when i feel one.

and the engine doesn't sound like it's at that rpm
sometimes i could be going at 4000 rpm and it would do that

I'm not doubting that it was engine cutoff, but, if the revs are flying from 4k to 8k and is hitting engine cutoff, then its pretty likely that there is something along the drivetrain thats letting go.

no, you don't get it!
the revs are not really up that high cause i can tell by the noise the engine makes
the needle just says that either because of a sensor or the tach
but i don't think a tach could cause a cutoff so i was leaning more on the sensor.
Drivetrain is on the bottom of my list of possibilities here

ok, my bad; I thought that the engine was revving. sorry

sensor, your tach has nothing to do with yoru fuel cut off. its just a display of how fast your distributor is spinning. So its a sensor

sure you weren't racing with your car not totally warmed up? sometimes the fuel cut off wont let you rev over a certain point if the engine is cold.

I don't understand why the kid in the neon's race has anything to do with this. . .

junkytri · 06-22-2003, 09:37 AM

how much do you think it cost to replace a sensor?

Preludegod · 06-22-2003, 02:12 PM

you would have to replace your speedo sensor which is not that hard to do, i jhave one for sale if your interested

If the tach is going high, its not the VSS (vehicle speed sensor)
Its most likely something in the distrubiter. Or dare I say ECU.

junkytri · 06-23-2003, 01:10 PM

ecu? sounds expensive; if the cost to fix is too high then should i just remove the rev limiter?
