I got the car with the motor and manual tranny in, yes, auto to manual. It is a 1999 Accord LX with an OBD1 H22 swap, manual tranny conversion, OBD1 P13 ECU and OBD2-OBD1 conversion harness. Got it running and what not, but has no speedometer and throws a code 41 (primary 02 sensor heater). Any pointers?

No one has a clue?

if you have non workign speedomoter your vss is either not hooked up, not working, or has broken wiring.

 

no speedomoter = no vtec

 

as far as the ck eng lite/code, which O2 sensor wiring did you use? there's one on the manifold and the other is at the catalytic conv. if you're using the O2 wiring from the cat for your source, that's where your problem is. use the wiring of the manifold that runs under the disributor. if that doesn't work, make sure your O2 sensor is good, and if all else fails check your wiring.

the speedo prob is either the vss itself or wiring. swap it out with a known good vss to narrow it down.

 

I used the Primary 02, the front one. Have a new sensor in there too. I have the harness pulled out again, and am going to check for broken wires with the digital voltmeter, that is my last idea...

Got the 02 sensor problem fixed. Turns out on the OBD1 P13, the heater circuit gets its power from the coolant sensor circuit. So, I just tapped into it, and bingo, no more code...
Now for the VSS.
