DTC P2BF6-00: Exhaust Shutter Valve Position Sensor Circuit Low Input: Notes

DTC P2BF6:00 PCM (SKYACTIV-G 2.5 - WITH CYLINDER DEACTIVATION) DETECTION CONDITION AND POSSIBLE CAUSE

DTC P2BF6:00	Exhaust Shutter Valve Position Sensor Circuit Low Input
DETECTION CONDITION	If the input voltage at the PCM terminal 1AL is less than 0.107 V for 5 s, the PCM determines that the exhaust shutter valve position sensor circuit has a malfunction. MONITORING CONDITIONS Battery voltage: 8 V or more Diagnostic support note This is a continuous monitor (other). The master warning light illuminates if the PCM detects the above malfunction condition during the first drive cycle. The check engine light does not illuminate. FREEZE FRAME DATA/Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	PCM restricts engine torque.
POSSIBLE CAUSE	Exhaust shutter valve/exhaust shutter valve position sensor connector or terminals malfunction PCM connector or terminals malfunction Open circuit in wiring harness between the following terminals: Exhaust shutter valve terminal C-PCM terminal 1D Exhaust shutter valve terminal E-PCM terminal 1P Short to ground in wiring harness between the following terminals: Exhaust shutter valve terminal C-PCM terminal 1D Exhaust shutter valve terminal E-PCM terminal 1P Exhaust shutter valve position sensor signal circuit and ground circuit are shorted to each other Exhaust shutter valve position sensor (built-into exhaust shutter valve) malfunction PCM malfunction
