P2018 trouble code definition

Intake Manifold Runner Position Sensor/Switch Circuit Intermittent Bank 1

What the P2018 code means

P2018 is an OBD-II generic code for the engine control module (ECM) detecting a an intermittent failure in the intake manifold runner position sensor/switch circuit causing the ECM to turn on the Check Engine Light and set the P2018 code.

What causes the P2018 code?

  • The engine control module (ECM) tests the intake manifold runner position on startup to test its operation and monitors the position during vehicle operation and will set a fault code P2018 if the signal return is erratic or intermittent from the sensor.

  • The signal from the intake manifold runner is erratic but still within specification when it works.

What are the symptoms of the P2018 code?

  • The Check Engine Light will be illuminated and the code is set in ECM memory as a fault.
  • The engine may have low power conditions or acceleration issues.
  • The engine miles per gallon may suffer over time.

How does a mechanic diagnose the P2018 code?

  • Scans codes and documents the code in the ECM and look at the freeze frame data for failure

  • Checks the wire connections to the sensor for loose or corroded connections

  • Performs the manufacture pinpoint test on the sensor to verify the failed sensor

Common mistakes when diagnosing the P2018 code

  • Clearing ECM memory codes before checking the freeze frame data, so the failure may be duplicated and repaired

  • Failing to clear the ECM codes after the codes are fixed

  • Replacing parts when the wiring has been rubbing through from a loose harness tie down

How serious is the P2018 code?

Code P2018 is a code for the intake manifold runner sensor not working correctly and the problem may not cause major issues with everyday driving except on acceleration.

What repairs can fix the P2018 code?

  • Replacing the intake manifold runner sensor for bank 1
  • Repairing the wiring harness or connector to sensor
  • Replacing the ECM for an internal faulty circuit

Additional comments for consideration regarding the P2018 code

Code P2018 is to alert you that bank 1 signal is erratic and may not affect the component from working except when the signal is not working. The problem may be very intermittent or may be very often depending on failure.
