The P2016: Intake Manifold Runner Position Sensor/Switch Circuit Low Bank 1 indicates that the voltage in the intake manifold runner position sensor or switch circuit for Bank 1 is lower than expected. This could be caused by a faulty sensor or switch, low voltage, or wiring and connector issues.
P2016 – Quick Overview
Code | Information |
---|---|
Meaning | P2016: Intake Manifold Runner Position Sensor/Switch Circuit Low Bank 1 |
Is it serious? | Yes, this can lead to improper intake manifold runner positioning, reduced engine performance, and drivability issues. |
Possible causes | – Low voltage in the position sensor or switch circuit – Faulty sensor or switch – Wiring or connector issues |
How to diagnose? | – Measure voltage in the sensor or switch circuit – Test the sensor or switch – Inspect wiring and connectors |
P2016 Meaning
The P2016: Intake Manifold Runner Position Sensor/Switch Circuit Low Bank 1 code indicates that the voltage from the intake manifold runner position sensor or switch on Bank 1 is below the manufacturer’s specified range. This sensor monitors the position of the intake manifold runner to optimize airflow for engine performance. A low voltage condition may cause incorrect positioning of the runner, leading to poor air intake and reduced performance.
Step-by-step diagnostic guide
Action | Description | Tools Needed |
---|---|---|
Check for Other Codes | Use an OBD-II scanner to check for additional codes related to the intake manifold runner system or other related issues. Additional codes may provide further context for diagnosing the problem. | OBD-II Scanner |
Measure Voltage in the Sensor/Switch Circuit | Use a multimeter to measure the voltage in the intake manifold runner position sensor or switch circuit. Compare the reading to the manufacturer’s specifications to verify if it is too low. | Multimeter |
Test the Sensor or Switch | Test the intake manifold runner position sensor or switch to ensure it is functioning correctly and sending the correct signals for intake runner control. | Multimeter, Diagnostic Tool |
Inspect Wiring and Connectors | Visually inspect the wiring and connectors related to the intake manifold runner position sensor or switch. Look for any signs of corrosion, damage, or disconnection that could result in low voltage. | Flashlight, Multimeter |
Test the Intake Manifold Runner Control System | Test the overall runner control system, including actuators and sensors, to ensure proper function and that the low voltage issue is not affecting overall performance. | Diagnostic Tool |
Repair or Replace Damaged Components | Repair or replace any damaged wiring, connectors, or faulty sensors to restore proper voltage and operation of the intake manifold runner position sensor circuit. | Wiring Repair Kit, Multimeter |
Clear the Code and Test Drive | After completing repairs, clear the P2016 code using an OBD-II scanner and take the vehicle for a test drive to ensure the issue is resolved. | OBD-II Scanner, Vehicle Owner’s Manual |
Recheck for Codes | After the test drive, re-scan the vehicle to confirm that the P2016 code has not returned. | OBD-II Scanner |
