DTC P1140 IVT CONTROL POSITION SENSOR





Component Description
The intake valve timing control position sensor is located in front of the cylinder head. This sensor detects a signal (intake valve position) generated by the protrusion of camshaft sprocket and sends it to the ECM. This sensor is not used to control the engine system. It is used only for the on board diagnosis of intake valve timing control.

Diagnostic Procedure








Component Inspection
1. Disconnect intake valve timing control position sensor harness connector.
2. Loosen fixing bolt of the sensor.
3. Visually check the sensor for chipping.
4. Check resistance between terminals 2 and 3.
Resistance: 600 - 740 Ohms [at 20 °C (68 °F)]
If NG, replace intake valve timing control position sensor.
