DTC P2016:00

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 (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
POSSIBLE CAUSE	Variable tumble shutter valve switch connector or terminals malfunction Short to ground in wiring harness between the following terminals: Variable tumble shutter valve switch terminal B-PCM terminal 2AU Variable tumble shutter valve switch terminal C-PCM terminal 2R PCM connector or terminals malfunction Variable tumble shutter valve switch signal circuit and ground circuit are shorted to each other Open circuit in wiring harness between variable tumble shutter valve switch terminal B and PCM terminal 2AU Variable tumble shutter valve switch malfunction PCM malfunction

DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot data on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT VARIABLE TUMBLE SHUTTER VALVE SWITCH CONNECTOR CONDITION Switch the ignition to off. Disconnect the variable tumble shutter valve switch connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the terminal and/or connector, then go to Step 9.
3		No	Go to the next step.
4	INSPECT VARIABLE TUMBLE SHUTTER VALVE SWITCH CIRCUIT FOR SHORT TO GROUND Variable tumble shutter valve switch connector is disconnected. Inspect for continuity between the following terminals (wiring harness-side) and body ground: Variable tumble shutter valve switch terminal B Variable tumble shutter valve switch terminal C Is there continuity?	Yes	If the short to ground circuit could be detected: Repair or replace the wiring harness for a possible short to ground. If the short to ground circuit could not be detected: Replace the PCM (short to ground in PCM internal circuit). (See PCM REMOVAL/INSTALLATION ). Go to Step 9.
4		No	Go to the next step.
5	INSPECT PCM CONNECTOR CONDITION Disconnect the PCM connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the terminal and/or connector, then go to Step 9.
5		No	Go to the next step.
6	INSPECT VARIABLE TUMBLE SHUTTER VALVE SWITCH SIGNAL AND GROUND CIRCUITS FOR SHORT TO EACH OTHER Variable tumble shutter valve switch and PCM connectors. Inspect for continuity between variable tumble shutter valve switch terminals C and A (wiring harness-side). Is there continuity?	Yes	Repair or replace the malfunctioning wiring harness, then go to Step 9.
6		No	Go to the next step.
7	INSPECT VARIABLE TUMBLE SHUTTER VALVE SWITCH POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT Disconnect the variable tumble shutter valve switch and PCM connectors. Inspect for continuity between variable tumble shutter valve switch terminal B (wiring harness-side) and PCM terminal 2AU (wiring harness-side). Is there continuity?	Yes	Go to the next step.
7		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 9.
8	INSPECT VARIABLE TUMBLE SHUTTER VALVE SWITCH Reconnect the variable tumble shutter valve switch and PCM connectors. Inspect the variable tumble shutter valve switch. (See VARIABLE TUMBLE SHUTTER VALVE SWITCH INSPECTION ). Is there any malfunction?	Yes	Replace the variable tumble shutter valve switch, then go to the next step. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION ).
8		No	Go to the next step.
9	VERIFY DTC TROUBLESHOOTING COMPLETED Make sure to reconnect all disconnected connectors. Switch the ignition to ON (engine off). Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE ). Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST ). Is the same DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION ). Go to the next step.
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE ). Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE ).
10		No	DTC troubleshooting completed.
