So, I have an issue at hand and need some help badly.
I recently got a 7th gen Vti with its own D16W9 engine and there is check engine light and the error code I am getting is P1607 - Powertrain Control Module Internal Circuit Malfunction. The result is poor fuel average.
I googled this issue and it seems that my ECU isn't working properly and the solution is to change the ECU. The ECUs for manual transmission are quite expensive. So, I wanted to inquire if anyone has faced this error and how was it resolved?
Also, if you know if this ECU can be repaired? I can visit Rawalpindi for this.
