2004 Hyundai Accent 1.6L non-ABS P0501 No Speedo and Odometer

Car shifts fine, everything basically works except for no speedometer and odometer. Replaced parts that I shouldn't have like the Vehicle Speed Sensor and VSS gear. Other people suggested that there is another speed sensor at the front wheels but I was unable to locate such sensor. Checked all fuses and none were blown. Checked the 3 wires at the VSS plug, ground is good, battery wire showing around 11 volts but the signal wire is at 7 volts. Is that too high? Have not checked the VSS wiring harness but did take the instrument cluster out and used electrical cleaner. I appreciate any help!!

The service info indicates the signal wire should have 6.5V - 7.5V with it disconnected so your 7v reading rules out a signal wire issue. I would jump the power feed and the ground on that plug with a test light to load them and make sure those are good. If that's good then I would try a bypass test by checking the vehicle speed pid on a scan tool while grounding the signal wire really fast. Might have to do this with the engine running if key on is not successful.

Hey there, There was a bulletin out for this fault but for a 2001, and that vehicle appears to have a VSS, and a front right wheel speed sensor.

there should be 3 wires at your VSS, you should have battery voltage at one, around 7 volts are the other with VSS disconnected, and key on/engine off,

and chassis ground.

what kind of ground reading are you getting ( ground pin to neg. on battery with DVOM ) ??

OMG, this is above and beyond what I expected. Thank you so much Jreardon!!!! I'll start digging into this during the weekend.

Hey tech, I don't remember the ground reading since my friend was the one who used the DVOM. He said the ground was good but I'll use my own an annotate the results.

I'm really, really sure that there isn't a speed sensor on any of the front wheels. A few days ago I removed both front tires to confirm but I'll check again and take pics.

Thanks for all your help!!

you shouldnt have a wheel speed sensor, only the VSS, Jreardon gave you the same info I was looking at.

What kind of scan tool are you using?? can you get live data??
if so does the Engine control module read VSS while driving??

I'm using the BlueDriver scan tool. I am able to get live data and enabled MPH but the reading showed 0.

continue checking ground, and wiring from printouts from earlier.
