Circuit/System Verification

IMPORTANT: DTC U0107 sets if the battery voltage is low or the PCM is replaced or reflashed. If the customers concern is slow cranking, if the engine is not cranking because the battery voltage is low, or if the PCM was replaced or reflashed, ignore DTC U0107. Clear any DTCs from memory that may have set from the low battery voltage condition.
  1. Ignition OFF for 30 seconds.
  2. Ignition ON. The TP Sensor 1, TP Sensor 2, APP Sensor 1, and APP Sensor 2 voltage parameters should not all read 0 volts.
  3. Operate the vehicle within the Conditions for Running the DTC, or within the conditions that you observed from the Freeze Frame/Failure Records data.
