DTC P2016-00: Variable Tumble Shutter Valve Position Sensor Circuit Low Input: Notes

DTC P2016:00	Variable tumble shutter valve position sensor circuit low input
DETECTION CONDITION	The PCM monitors input voltage from variable tumble shutter valve position sensor. If input voltage is below 0.1 V for 4.9 s , the PCM determines that the variable tumble shutter valve position sensor circuit has a malfunction. Diagnostic support note This is a continuous monitor (CCM). The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle. FREEZE FRAME DATA (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	-
POSSIBLE CAUSE	Variable tumble shutter valve position sensor connector or terminals malfunction Short to ground in wiring harness between the following terminals: Variable tumble shutter valve position sensor terminal B-PCM terminal 2AU Variable tumble shutter valve position sensor terminal C-PCM terminal 2R PCM connector or terminals malfunction Variable tumble shutter valve position sensor signal circuit and ground circuit are shorted to each other Open circuit in wiring harness between variable tumble shutter valve position sensor terminal B and PCM terminal 2AU Variable tumble shutter valve position sensor malfunction PCM malfunction
