3242-4 DPF Inlet Temperature Sensor Voltage Below Normal
3246-4 DPF Outlet Temperature Sensor Voltage Below Normal Note: A -3 code is detecting an open circuit or +B short circuit of the sensor or the wiring harness.Note: A -4 code is detecting a ground short circuit of the sensor or the wiring harness.Note: Diagnostic codes for a short circuit or an open circuit are most commonly caused by an engine harness routing near a connector. Refer to Special Instruction, REHS7774 for more information on repairing the jumper harness.
