Maddix Posted October 8, 2023 Report Share Posted October 8, 2023 Hello, Quite recently got my Z build and tuned, however, the car from time to time goes into safety mode - engine goes to idle and no Throttle pedal response. I can floor it and nothing happens. I'm running Link G4+ Thunder on VQ35DE twin turbo. Cannot figure out whats going on, would appreciate some guidance. I've attached two logs with the errors and the map. Getting these codes: [11:53:53 AM] ECU Fault Code 75: E-Throttle 1 TP /Target Error [11:53:53 AM] ECU Fault Code 73: Aux 9/10 Supply Error [11:53:50 AM] ECU Fault Code 76: TP(main) /TP(sub) tracking Error 350z 2nd log.llg 350z.llg 350zVQ35DETT.pclr Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 8, 2023 Report Share Posted October 8, 2023 Most likely one of the throttle position sensors is failing. These are not replaceable they come as part of the complete throttle body. You can see in the log below where TPS sub (cyan) does a sudden step at 3:44 while the TPS main is showing a flat line, both sensors are connected to the same shaft so that should always show near identical values. The ECU only allows a few percent error between the two as it has no way to know which one is right. Quote Link to comment Share on other sites More sharing options...
Maddix Posted October 13, 2023 Author Report Share Posted October 13, 2023 Thank you for the feedback. I will get a new Throttle body and test it. Will update the thread if resolved. Quote Link to comment Share on other sites More sharing options...
