P1106 – OBD-II DTC

OBD-II DTC P1106 – KOER Not Able To Complete KOER Aborted

DTC P1106 meaning

DTC P1106 refers to a diagnostic trouble code indicating that the On-Board Diagnostics II (OBD-II) system has detected an issue during the Key On Engine Running (KOER) test. Specifically, it signifies that the system was unable to complete the KOER test due to an aborted condition. This code is often associated with the intake air temperature sensor or the mass airflow sensor, which are critical for proper engine performance and emissions control.

DTC P1106 symptoms

Common symptoms associated with DTC P1106 may include:

• Check Engine Light illuminated
• Engine performance issues, such as rough idling or stalling
• Decreased fuel efficiency
• Unusual engine noises
• Difficulty starting the engine

DTC P1106 causes

Several factors can lead to the triggering of DTC P1106, including:

• Faulty intake air temperature sensor
• Malfunctioning mass airflow sensor
• Wiring issues or poor connections in the sensor circuits
• Vacuum leaks in the intake system
• Faulty engine control module (ECM)

DTC P1106 seriousness

The seriousness of DTC P1106 can vary depending on the underlying cause. While it may not immediately threaten vehicle safety, it can lead to:

• Increased emissions
• Reduced engine performance
• Potential long-term damage to engine components if left unaddressed

It is advisable to diagnose and resolve the issue promptly to maintain optimal vehicle performance and compliance with emissions regulations.

How to diagnose DTC P1106

To diagnose DTC P1106, follow these steps:

1. Use an OBD-II scanner to confirm the presence of the P1106 code.
2. Check for any additional trouble codes that may provide more context.
3. Inspect the intake air temperature and mass airflow sensors for physical damage or disconnections.
4. Test the sensors using a multimeter to ensure they are functioning within specifications.
5. Examine the wiring and connectors for signs of wear, corrosion, or loose connections.
6. Check for vacuum leaks in the intake system that could affect sensor readings.
7. Clear the codes and perform a KOER test to see if the code reappears.

How to fix DTC P1106 step-by-step instructions

To fix DTC P1106, follow these step-by-step instructions:

1. Confirm the DTC P1106 code using an OBD-II scanner.
2. Inspect the intake air temperature and mass airflow sensors for any visible damage.
3. If damaged, replace the faulty sensor with a new one.
4. Check the wiring and connectors for the sensors repair or replace any damaged components.
5. Inspect the intake system for vacuum leaks and repair as necessary.
6. Clear the DTC using the OBD-II scanner.
7. Perform a KOER test to ensure the code does not return.
