P1843 Fault Code: Understanding The Description And Troubleshooting Steps
The P1843 fault code refers to a problem with the 1-2 Shift Solenoid Circuit in your automobile. This code is triggered when the Powertrain Control Module (PCM) detects a continuous short to power on the feedback circuit of the 1-2 Shift Solenoid for 4.3 seconds. To understand this fault code, we need to look at the conditions under which it occurs.
The engine runtime should be over 5 seconds, and the system voltage should be between 8 and 18 volts. Additionally, the Fuel Cutoff should be inactive, and the PCM should have commanded the 1-2 Shift Solenoid to be on.
When these conditions are met and the PCM detects a continuous short to power on the 1-2 Shift Solenoid feedback circuit, the P1843 fault code is triggered.
This indicates a high input voltage issue with the 1-2 Shift Solenoid Circuit.
If you encounter this fault code, it is important to have it diagnosed and repaired by a qualified technician. Ignoring this issue can lead to transmission problems and potential damage.
