got a code 54. My friend and I just put a JDM ITR swap in his gsr. The gsr had this sensor but the ITR motor does not. How can we bypass this? He is using a p73 ecu. thanks!
both the gsr and itr are 97. the p73 ecu is supposed to be the stock one that originally came with the itr motor... so 97 too i guess.
If the ECU that you are using is truly the ECU that came with that ITR engine them it shouldn't be looking for the sensor. What is code 54?
