the CJ125 throws the error "240". "255" means everything is OK, everything else means nothing good :roll:

The error in your case should be a shortcircuit to ground on the sensorlines "Virtual Ground" (yellow) and "Nernstvoltage" (black). Please check this first.

Than: You meantioned that there is no green line on your sensor. Thats OK :wink:
But: There is a calibration resistor build into the sensors connector. So you have five cables from sensor to connector and than you need six cables from the connector to ECU. Did you do so?

Best Regards

Hi sebastian,

1 more question,

if i measure from the wideband kable to the daughterboard. i measure next connections


LSU_IP = red.
LSU_IA = Green
LSU_UN = black
LSU_VN = yellow
+12V_LSU =brown / grey
+12V_LSU =white

Hi Pieter,

so on one board the sensor works and on the other three it doesn't?

Connections seem to be OK. Resistances too.
Maybe there is an error on the board?

Hi,

thanks, yes, i have had 1 bmw ecu that works, 1 kdfi cinch that works, first order.
4 KDFI cinch that wideband doesn't work, all ordered later on.

they are al going back for check and repair. we will see. order 3 new one's as wel, they are nice ecu's with or without wideband.
