speedometer

[wiseguy01]

okay maybe you guys can help me i have a 93 accord lx and the speedo doest work and the mil says my vss is faulty so i replaced it and still the same problem so i tried honda they gave me the shop manual to read and troubleshoot and im still in the same boat with no paddle help please

check for voltage to 1. the ecu (it should be pulsing when the car is moving) and 2. to the cluster

[wiseguy01]

would my vss be causing my tranny to shift erratic too

[Greenblurr93]

define erratic... a tranny uses pressure more than anything, but im not tranny guy.. so dont quote me, they give me the heeby geebys...

[wiseguy01]

ok i figured out my erattic shifting it was the timing retarded too much so i advanced it a little more and the problem went away but i still have to check my voltage to the ecu for my vss the little things that matter the most

[orb666]

if the speedometer does not work. it maybe an Alternator SP fuse or your VSS (Vehicle Speed Sensor). If your unit is an old one (1999-below) look for the 2p connector under dash and use a female 2p connector to short it. then turn the ignition switch to on. look for the MIL or check engine code (number of blinks) then reply to me the number of blinks.

[wiseguy01]

it says code 17 vss. and vss has power and resistance all i need to do is check power to my ecm

[Greenblurr93]

but is it within spec? if its not sending enough voltage or too much votage back to the ECU then it still could be bad

[wiseguy01]

yeah i used this program called on demand 5 it tells u how to troubleshoot and labor rates etc.. shop edition im just real lazy and got alot going on to tear my floorboard apart to get to my ecm

[wiseguy01]

ok heres the new problem i got troubleshooting papers from honda and they said to jack the car up and backprobe the orange wire on my vss and turn the wheel and the voltmeter should be pulsing from 0 to 12v and it doesnt do that so it said to replace vss but i already replaced it twice and the number 1 fuse isnt blown so is it possible to get to bad vss's from star auto parts and will the third time be the charm..

[Greenblurr93]

are you having a friend turn the wheel while you back probe? is the key set to the on position? have a friend turn the wheel as fast as he can while the key is "on". i dont think an power will be coming from it if the key is off

[wiseguy01]

yeah i had the key on and turning the wheel

[wiseguy01]

ok hers my next question if the vss circuit had a short wouldnt it blow the #1 fuse cause if so my #1 fuse isnt blowing.. this ones for you blur

[wiseguy01]

HELP BLUR I HAVE A PROB WHEN I WENT TO AUTOZONE.COM AND LOOKED UP MY VSS IT GAVE ME TWO AND I CHECKED AND MY CAR HAS BOTH OF THEM SO WHAT IF I HAVE BEEN REPLACING THE WRONG ONE THE WHOLE TIME PLEASE GIVE ME SOME INSIGHT I WILL POST A LINK SO YOU CAN SEE AND EXPLAIN TO ME WHAT THE OTHER SENSOR IS COULD IT POSSIBLY BE THE WHEEL SENSOR

got both huh? well... the first one you replaced obviously should be fine now... test the other one, if its faulty, then replace it and chaulk it up as a lesson learned..
