P3138: Your Engine’s Oxygen Sensor Needs Attention
The P3138 code is related to the intake flap for airflow control.
This code indicates that there is a difference in the control circuit for the intake flap. The intake flap is responsible for altering the airflow into the manifold based on the load conditions. A position sensor is used to monitor the valve for any electrical or mechanical faults.
To validate the position feedback, an actuator test can be performed or live data can be analyzed using an oscilloscope. The rate of intake swirl and turbulence is critical for fuel mixture formation and agitation.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P3138 fault code. This code is usually caused by a faulty intake manifold runner position sensor, an open or shorted sensor harness, a poor electrical connection in the sensor circuit, or a faulty intake manifold runner control solenoid valve. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
