zwhitebread Posted October 8, 2020 Report Share Posted October 8, 2020 I am getting a lambda 1 error. The Error is number 35 which says "open Circuit RComp Invalid - Open circuit on senor calibration resistor." Its on a link Fury. The software is up to date. I double checked all the wiring and everything appears to be connected and wired correctly. Is this going to be a sensor problem or an internal ecu problem? Any help is appreciated.

Simon Posted October 8, 2020 Report Share Posted October 8, 2020 Sensor has been wired with the factory connector on the sensor, so 6 wires on ECU side and 5 off to the sensor? Quote Link to comment Share on other sites More sharing options...
MichaelR32GTR Posted October 9, 2020 Report Share Posted October 9, 2020 I had similar issues and was the non resistor spark plugs I was using so check them also Gsab 1 Quote Link to comment Share on other sites More sharing options...
zwhitebread Posted October 9, 2020 Author Report Share Posted October 9, 2020 The lambda sensor itself is a link wide band sensor that is wired directly into the internal lambda controller using a a link wiring loom. So yes 5 wires coming from the ecu and 6 going into the sensor with the 6th being 12v. Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 9, 2020 Report Share Posted October 9, 2020 The error suggests the ECU is not seeing the expected resistance on the calibration resistor. Unplug the B plug at the ecu end and measure resistance between the MES and APE wires/pins (at the ecu plug). A valid sensor would be 30-300ohms.

zwhitebread Posted October 17, 2020 Author Report Share Posted October 17, 2020 So the resistance was 93 ohms. I found that one of the female pins was a little loose fitting. I fixed that and checked the rest of the pins and the are all fine. I also double checked the wiring and everything has continuity from the O2 sensor to the pins on the B plug to the ECU and all are wired to the correct pins. Now i am getting three errors. It starts with error 44 RE over voltage. Then it shows error 2 internal controller error. Then it shows error 51 cant read switch on. Any insights on these issues?

Adamw Posted October 18, 2020 Report Share Posted October 18, 2020 Ok that sounds very odd, I dont have any good feeling for what could cause all of these odd errors. As a start can you give us some photos of the wires going in to the lambda plug so I can confirm pinout etc (may have to peel the boot back etc if fitted).

zwhitebread Posted October 18, 2020 Author Report Share Posted October 18, 2020 Ok. I made up a PDF document with pictures hopefully it is clear enough. Let me know if its not clear or you need/want anything specifically that I missed. Its to big to attach so here is the link to it in dropbox. Let me know if that does work for you. https://www.dropbox.com/s/759sn5ko5qzumka/O2 sensor wiring.pdf?dl=0 Thanks! Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 18, 2020 Report Share Posted October 18, 2020 Thanks, I agree it looks like the pinout is correct. After seeing the photos this all kind of looks fairly well used, I initially assumed this was a new install that we were discussing. Has it been working correctly previously and it just started giving the error or is it a fresh install and never worked from the start?

zwhitebread Posted October 18, 2020 Author Report Share Posted October 18, 2020 The car itself has been raced a lot but this install is relatively new. It has been raced 2 times with the current setup. (it’s a rally car and the last race was dusty, probably why it looks so used). The sensor had worked previously but I have been having issues with random cuts since the current setup was done. In previous logs it always had the AFR but when I looked at this log it didn’t read at all. Do you think that the sensor itself could be the problem? Or any other specifics that I should be looking for? Or is there any other information that you need? thanks Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 18, 2020 Report Share Posted October 18, 2020 I suspicious the sensor is dead from the info you have given above. Unless there is a bad connection somewhere but the multiple errors suggest something more. I think the next logical step is try a new sensor.

zwhitebread Posted October 18, 2020 Author Report Share Posted October 18, 2020 Ok. I will get one ordered. In the meantime I have a separate question. I am getting these errors from the Can 2 status. It is transmitting to a dash2pro. Everything on the dash appears to be working. Any idea what could cause this? the weird part is if i go to the can setup, change nothing and hit apply the errors go away and dont come back.

Adamw Posted October 19, 2020 Report Share Posted October 19, 2020 If the CAN errors go away and stay away when you reset the bus while everything is powered up then I suspect the most likely reason is the Dash2pro is slow to boot-up so the ECU logs the error when the dash doesnt acknowledge the ECU quick enough.
