ACPMick Posted August 2, 2020 Report Share Posted August 2, 2020 Hi everyone. So this is my first time installing a link ecu. I am pretty good with electrics but I am not a professional. I installed plug and play link 4g+ into my 300 zx. I am having a two major issues. 1: I have reconfigured AN temp2 from fuel temp to IAT. I am using an AEM IAT so I set it up for ohm input, Celsius output, 10 increments and then I used cal table 1 and entered some numbers that seem to be working for people. I constantly get an error 46, volt at 5 volts. I checked the source wire to the sensor, it has five 5V as it should. I checked the brand new IAT, it came back 2.4K ohms, which seems reasonable. Then I checked the signal return wire with the sensor disconnected as a last resource and I am seeing 5V in there as well. I seriously do not think I messed up the harness this bad. I cannot make sense of it. What am I missing here? 2: My CEL is not coming on although the laptop is showing that it should be flashing. Not even at key on. But when I turn off the ignition it flickers on so it must be connected. Any help would be appreciated. Quote Link to comment Share on other sites More sharing options...
