I change the TPS still have same code after replacement P0122 the problem code for TPS, and this code P01684 still show up
P01684 just says that the battery has been disconnected within the past 50 starts. If you have already replaced the TPS and still get the P0122 code, it could be a short in the wiring or a problem with your Powertrain Control Module. Other names for the PCM is ECM and ECU. Engine Control Module and Engine Control Unit
