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): Description
The Swirl Control Valve (SCV) position sensor is a non-contact type.
The position sensor measures the opening angle of the SCV. The sensor is reliable and accurate, as it is electrically controlled by Hall elements.
The ECM's IACI terminal voltage increases in correlation with the opening angle of the SCV. When the SCV is fully closed, approximately 0.6 V is applied to the IACI terminal. When the SCV is fully open, approximately 3.6 V is applied to the IACI terminal.
When the output voltage of the IACI terminal deviates from the standard range, the ECM determines that a malfunction has occurred in the position sensor and outputs a DTC. ECM POWER SOURCE CIRCUIT .
| DTC No. | DTC Detection Connection | Trouble Area |
|---|---|---|
| P2014 | SCV position sensor output voltage flutters up and down beyond the normal operating range (Less than 0.2 V or more than 4.8 V for more than 0.5 seconds) (Open or short) |
|
| P2016 | SCV position sensor output voltage is less than 0.2 V for more than 0.5 seconds (Short) |
|
| P2017 | SCV position sensor output voltage is more than 4.8 V for more than 0.5 seconds (Open) |

HINT:
After confirming DTC P2014, P2016 or P2017, use the intelligent tester to confirm the SCV ANG SENS D4 (SCV position sensor output voltage) from DIAGNOSIS / ENHANCED OBD II / DATA LIST / ALL.
| SCV ANG SENS D4 | Malfunction |
|---|---|
| 0.2 V or less |
|
| 4.8 V or more |
