Intake Manifold Runner Position Sensor/Switch Circuit Intermittent Bank 1
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.
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.
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
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
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.
