Car : 99 Civic Sedan Ex
Motor : d16y8
Cluster : 99 Si
As the title states, I'am having a bit of trouble with Tach and Speedo working . I just recently bought the car in its current condition .. The previous owner said they both just stopped working one day while he was driving, all the other gauges and indicators work . I've been doing some reading and came across a common problem that Civics have with the VSS either going out or the connector plug going bad .. before I even went out to buy an Mulimeter I did a few recommended things .. First I got an OBD2 Scan Tool because i was getting a code, but everytime i went to scan the ecu there were no codes stored/no fault codes. I even tried jumping it at the service connector and the check engine light would just stay on and not flash . I also checked fuses 30-25-15 all were good even swapped them with new ones.. Second I swapped Clusters just to see if maybe that could of been it since I thought the speed sensor had nothing to do with Tach readings .. No dice, still didn't work.. Third I tried an different ecu, since my car has recently switched from Auto to Manual thinking they might of had the wrong ecu in . Still no dice . LASTLY I went bought a Multimeter so I could see if there's continuity on the connector and to see if there's a 5v pulse coming from the sensor it self .. Here's my results..
Key on:
Blk wire : 3.1
Blk/Ylw Wire : 0
Blue/white : 3.5
Key off :
BLUE/WHITE wire : 2.1
Blk/ylw : 9.5
Bllk wire : 1.6
I dont really know how to test the sensor itself but when I stuck the Probe where the key inserts into the top part of the gear and turned the wheel. I was getting 0.7 it would go up as i spent the wheel .. I went as far as pulling the plugs on the Cluster and testing the blue wire that went to both the Tach and Speedo and I wasn't getting any readings from the wire .. my question is, is the speed sensor dead*or do I have a short some where ?
