DTC P2016:00 [L5]: Notes

WARNING: This page is about a different car, the 2009 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.

DETECTION CONDITION & POSSIBLE CAUSES

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