Speed sensor question

Post by s2kseven » Mon Jun 01, 2015 6:03 pm

2011 K20Z3

I'm using a race technology dash2 - I don't have a speed sensor.
Anyone has a picture of any aftermarket speed sensor installed in the driveshaft?

Is the K20 has a VSS (vehicle speed sensor)?
Perhaps I can explore to use that unit to my dash2 ?

Thank you

No experience with the dash2 but I see no reason why the K20s own VSS couldn't be used. The VSS signal wire in the loom goes to pin 18 on connector A of ECU (White / Green) and the dash cluster. If you're after a wheel sensor then I see Race Tech sell them

A bit old but you might find this useful (dash2 with civic type R)

Thank you guys I appreciate it very much.
A lot of people can't make the K20 VSS to work....maybe my best bet is using an aftermarket as "smokin" suggested.
I will visit Race tech site.

Is this for the atom? You have a hall sensor for the speed. For the dash 2 you need to send the 5v feed from one of the connectors to power it. Have a lookat one of my old posts with aa link to the wiring diagram for it for the atom, or have a look at the blog section on my website.

K20Z3 with Race technology dash2.

I finally made my VSS works in my dash2. The reason why it didn't work, my k20 vss has a high frequency signal.
I bought the pulse & clean up divider from a taxi meter --- cheap $40.
I directly connected it to the honda k20 vss at the transmission. Just one wire (signal wire).
No brainer to setup -- very simple. Just in case you need a solution.
My speedometer, my odometer and my gear counter now works. My speedo & odometer also are accurate. The gear counter is working but at times there is a  discrepancy...but ok.

Thank you for the help
