Code P2018 Chrysler Description
The P2018 Chrysler code refers to an issue with the Intake Manifold Runner Position Sensor/Switch Circuit on Bank 1. This sensor is responsible for monitoring the position of the intake manifold runner, which helps control the airflow into the engine. When this sensor detects an intermittent signal or malfunction, it can lead to a variety of performance issues in the vehicle.
Common Causes of P2018 Chrysler
- Faulty Intake Manifold Runner Position Sensor/Switch: The sensor itself may be malfunctioning, sending incorrect signals to the engine control module.
- Wiring Issues: Corrosion, damage, or loose connections in the wiring harness connected to the sensor can cause intermittent signal problems.
- Vacuum Leaks: Any leaks in the vacuum system that controls the intake manifold runner can disrupt the sensor's readings.
- Carbon Build-Up: Accumulation of carbon deposits in the intake manifold can interfere with the proper functioning of the sensor.
- Electronic Control Module (ECM) Failure: A malfunctioning ECM can also cause issues with the sensor circuit.
Symptoms of P2018 Chrysler
- Check Engine Light: The most common symptom associated with this code is the illumination of the Check Engine Light on the dashboard.
- Rough Idling: The engine may idle roughly or inconsistently, indicating a problem with the intake manifold runner.
- Decreased Fuel Efficiency: A malfunctioning sensor can lead to poor fuel efficiency as the engine may not be receiving the correct air-to-fuel ratio.
- Engine Misfires: The engine may misfire or hesitate during acceleration due to incorrect airflow into the engine.
- Reduced Power: The vehicle may experience a loss of power or struggles to accelerate smoothly.
How to Fix P2018 Chrysler
- Diagnose the Issue: Use a scan tool to read the code and determine the exact cause of the problem.
- Inspect Wiring and Connections: Check the wiring harness connected to the sensor for any damage, corrosion, or loose connections.
- Test the Sensor: Test the Intake Manifold Runner Position Sensor/Switch to see if it is functioning correctly.
- Replace Sensor or Repair Wiring: Depending on the diagnosis, either replace the faulty sensor or repair any wiring issues.
- Clear Codes and Test Drive: After the repair, clear the error codes, and test drive the vehicle to ensure the issue has been resolved.

Frequently Asked Questions about P2018 Chrysler Code
What does the OBDII code P2018 mean for a Chrysler vehicle?
P2018 indicates an issue with the Intake Manifold Runner Position Sensor/Switch Circuit Intermittent on Bank 1, meaning the sensor or circuit is not providing consistent readings.
What are the symptoms of a P2018 code in a Chrysler?
Symptoms may include reduced engine performance, poor fuel economy, rough idling, hesitation during acceleration, and an illuminated check engine light.
What causes the P2018 code in a Chrysler?
Common causes include a faulty intake manifold runner position sensor, damaged wiring or connectors, carbon buildup in the intake manifold, or a malfunctioning intake manifold runner control actuator.
Can I drive my Chrysler with a P2018 code?
While the vehicle may still be drivable, continuing to drive with this code can lead to poor performance and potential engine damage. It’s best to resolve the issue promptly.
How do you diagnose a P2018 code in a Chrysler?
Diagnosis typically involves scanning for codes, visually inspecting the intake manifold runner control system, testing the position sensor, and checking for wiring or connector issues.
How is a P2018 code fixed in a Chrysler?
Repairs may include replacing the intake manifold runner position sensor, cleaning or replacing the intake manifold, repairing wiring or connectors, or replacing the runner control actuator.
What tools are needed to fix the P2018 code?
