What Does the P2079 Code Mean?
The P2079 code refers to a problem with the Intake Manifold Tuning (IMT) Valve Position Sensor or Switch Circuit. It indicates that the Powertrain Control Module (PCM) has detected an implausible signal from the IMT valve position sensor, which affects the airflow into the engine, particularly at higher speeds.
What Causes the P2079 Code?
This code can be triggered by several issues, including:
- Failure of the intake manifold tuning valve
- Malfunction of the Powertrain Control Module (PCM)
- Wiring issues or poor connections affecting the sensor signal
What Are the Symptoms of the P2079 Code?
Common symptoms associated with the P2079 code include:
- Check Engine Light illuminated
- Reduced engine performance
- Rough idling
- Decreased fuel efficiency
How Serious Is the P2079 Code?
The P2079 code is considered to have moderate severity. While it may not pose an immediate safety threat, it can lead to reduced engine performance and efficiency if not addressed. It is advisable to diagnose and rectify the issue within a reasonable timeframe to ensure optimal vehicle operation.
How to Diagnose the P2079 Code
Diagnosing the P2079 code typically involves:
- Using an OBD-II scanner to confirm the presence of the code and any related codes.
- Inspecting the wiring and connections for the intake manifold tuning valve position sensor.
- Testing the IMT valve and sensor for proper functionality.
- Checking the PCM for any faults or failures.
Common Repairs for the P2079 Code
Repairs for the P2079 code may include:
