Ryley Coker Posted September 5, 2021 Report Share Posted September 5, 2021 Link G4X, I installed an ethanol sensor, ran power wire to a 12v switch, got a good ground, and put the signal wire to DI6. The ecu is reading as inactive. I have gone into DI6 and set it as the ethanol sensor, but it still reads inactive. I have also turned on and off the pull up resistor. Thoughts? k fuku 1 Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 5, 2021 Report Share Posted September 5, 2021 That would suggest there is no signal, it should show active as soon as there is a frequency on the DI. Is it a Link sensor? Quote Link to comment Share on other sites More sharing options...

Is it a Link sensor? It is the GM sensor. Does you have to specify what sensor it is in the ecu? Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 5, 2021 Report Share Posted September 5, 2021 No they all use the same calibration as far as I know, but I have seen a couple of different pinouts. Do you know what model car it is off and which pins are which? Some have the pin labels molded into the plastic. Quote Link to comment Share on other sites More sharing options...

Adamw Posted September 5, 2021 Report Share Posted September 5, 2021 Ok, that looks similar to the one we sell. Do you have it wired like this: Quote Link to comment Share on other sites More sharing options...
Ryley Coker Posted September 5, 2021 Author Report Share Posted September 5, 2021 Yes its wired like that. I am going to double check the connection to the ecu tomorrow. Quote Link to comment Share on other sites More sharing options...
