DTC P2014: Intake Manifold Runner Position Sensor / Switch Circuit (Bank 1); DTC P2016: Intake Manifold Runner Position Sensor / Switch Circuit Low (Bank 1); DTC P2017: Intake Manifold Runner Position Sensor / Switch Circuit High (Bank 1): Procedure

1. Connect Techstream to the DLC3.
2. Turn the engine switch on (IG) and turn the tester on.
3. Enter the following menus: Powertrain / Engine / Active Test / Control the SCV Duty Ratio / All Data / IAC Sensor Voltage.
4. Check the output voltage of IAC Sensor Voltage while changing Control the SCV Duty Ratio from -100 to 100% (or from 100 to -100%) using the Techstream.

   Standard

   The voltage output of IAC Sensor Voltage remains between 0.2 to 4.8 V while Control the SCV Duty Ratio is driven from -100 to 100% (or from 100 to -100%).

   Control the SCV Duty Ratio operation	IAC Sensor Voltage (Normal)	Suspect failure area
   		IAC1 circuit short VC circuit open	VC and IAC1 circuit shorted IAC1 circuit open E2 circuit open	Sensor malfunction
   -100 %	0.2 to 1.0 V	Remain less than 0.2 V	Remain more than 4.8 V	Other than the voltage in the 2 columns to the left
   100 %	3.2 to 4.8 V	Remain less than 0.2 V	Remain more than 4.8 V

OK → See step   5 

NG: Go to next step 

1. Disconnect the E3 and E6 ECM connectors.
2. Disconnect the E56 SCV position sensor connector.
3. Measure the resistance according to the value(s) in the table below.

   Standard resistance (Check for open)

   Tester Connection	Specified Condition
   VC (E3-29) - VCX (E56-1)	Below 1 Ω
   IAC1 (E6-31) - VSX (E56-3)	Below 1 Ω
   E2 (E3-28) - E2X (E56-2)	Below 1 Ω

   Standard resistance (Check for short)

   Tester Connection	Specified Condition
   VC (E3-29) or VCX (E56-1) - Body ground	10 kΩ or higher
   IAC1 (E6-31) or VSX (E56-3) - Body ground	10 kΩ or higher
   E2 (E3-28) or E2X (E56-2) - Body ground	10 kΩ or higher

4. Reconnect the SCV position sensor connector.
5. Reconnect the ECM connector.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Disconnect the E56 SCV position sensor connector.

2. Turn the engine switch on (IG).
3. Measure the voltage according to the value(s) in the table below.

   Standard voltage

   Tester Connection	Specified Condition
   VC (E3-29) - E2 (E3-28)	4.5 to 5.0 V

4. Reconnect the SCV position sensor connector.

NG → See step   6 

OK: Go to next step 

NEXT: Go to next step 

1. Connect Techstream to the DLC3.
2. Turn the engine switch on (IG) and turn the tester on.
3. Clear DTCs.
4. Enter the following menus: Powertrain / Engine / Trouble Codes.
5. Read DTCs.
