Hey yall,

I have a 94 civic with a b16a swap. I bought the car already swapped, vtec has never worked for me. I've swapped solenoids, tried the JDM 2 wire vtec with a chip (Ended up with limp mode at 5500 instead, normally will rev hit redline, but no vtec) oul pressure is good etc etc, basically I've

tried everything.

Did some data logging, (Im not a tuner, just got a bluetooth deal an Tunerview) and appears my ecu (p30) is NOT getting a speed signal. So switched the vss. No change. Speedo works. Tach works. Just ecu isn't seeing that I'm moving apparently.

Planning to go with a CobraRTP on HTS, can I tune out the vss? Or is there a way I can bypass this? Or any ideas on a fix?

 

The VSS output wire goes to three different places, The cluster, cruise control module, and ECU. The blue and yellow wire should be the output from the sensor. I would recommend getting a voltmeter and ohm the wire from the sensor to the computer and see if the wiring is good. Take the pin locations at the connectors with a grain of salt

 

apologies for reviving this from the dead, but did you ever find a solution? I have the exact same issue in my ‘99 CR-V
