Hello everyone,

I am new to the forums, I am currently swapping a K20A2 driveline into my 1985 Fiat X1/9. This is the third conversion ive done so I am somewhat familiar with the wiring but need some help with the o2 sensor connections. I am trying to run only the Auto Meter wideband and the ECU isnt getting a signal from the sensor, signal + is wired to pin 19 in the C101 connector and signal - to pin 10. Is this correct?

The gauge appears to be reading correctly but the ecu cant see anything and recently threw the P0134 error code.

Help!

Thank you!

What version of K-Pro are you using?

Kpro V4

I've been looking and some forums say connect the signal positive to pin 15 in the E connector but its showing 4 volts when the car is running so I dont think thats correct for this harness, I just dont understand why it wont work using the factory O2S pins on the C101...

Ok I made some progress, switched the O2S signal negative to the correct pin (im an idiot) and now im getting error code P1162 A/F sensor slow response.

Any suggestions on where to go form here?

or should I just add a bung for a stock sensor and be done with it?

You cannot input a aftermarket wideband signal into the oem wideband wiring and expect it to work.

Since you have a K-Pro v4 you can input the wideband signal into the analog input on the K-Pro board and run in closed loop that way.
