welp, i think i have finally found why my speedo isnt workin anymore. I have a signal coming from the vss all the way to the ecu. but, im stillin throwin a code 17. I recently found out that i am running an automatic ecu. could this be my problem. the car is 98 civic, with a 94 b18c. It had been working for as long as i have had the motor in there until recently.

i have
replaced vss
checked all wires

is there a way i can tell that the ecu is bad? any suggestions on how to fix this?

 

Search ''vss'',''speedo problems'',''ecu problems''.

It seems like everyone is making threads that can all be found by searching.

Goodluck with your topic , but i know it can be found searching

 

i already searched. got useless info. everyone seems to be having the same problem i am. most are also about the plug on the transmission. mine works fine, its not "wiring" its something connected to the wiring... more than likely my ecu.

 

why not take apart the ECU and see>? or find the code part that tells you what kind fo ECU it is?wait a minute I dont think they made the GSR in an auto? what ECU are you running?

 

i had the same problem and what i did i i pulled the sensor out and cleaned out all the gunk and carbon that builds up on it,now it works like new.Trust me man ,try this before u waste cash on a new part

 

its a brand new sensor. i tried cleaning out the other one before i got it, still no dice.i thought there was maybe a short in the wire some where so the ecu wasnt gettin the signal. When i tested continuity it was cool...<???> i would really like to fix this all ideas are appreciated.

by the way when i cleaned it i took it out of the transmission and pulled the sensor off the mechanical piece. wiped all that **** outta there and hooked it back up.

i dont know how to tell if the ecu im running is manual or auto i know its a p72. it also says AT on it. makin me think its an auto, it very well might not be though.

 

bump it up, tried a friends b16 ecu...... ran like **** and still no speedo, so im hopeful that mine isnt a lose yet. any help??

 

did u try cleaning the contacts inside the plug? also did u check to make sure the grounds (on the thermostat housing, tranny) are good and solid?

 

where is the ground off of the trans? i checked the plug for continuity, wouldnt that determine if it was working or not?

 

On my stock 99 hatch [D16Y7] there is a ground wire from the passenger side frame rail to a bracket on the tranny.

 

bump it up,

i fucked with it some more today. Checked the plug and it was bent in itself. I couldnt find another one so in haste i cut the ****** off. my **** still doesnt work, and i really miss vtec. help me.....
