Easy Diagnosis Of Engine Error OBD Code P2079
Here are some steps which you should follow in order to diagnose this P2079 fault code:
- To start with you will have to visually inspect all wiring, connectors, and components associated with the intake manifold tuning valve control circuit for engine bank 1. You should look for any loose, corroded, or damaged wiring, connectors, or components.
- After making the repairs, clear the code and test the system by test driving the vehicle to see if the code returns. Also, the you should download the freeze frame data and any stored trouble codes, as this allows them to repair codes in the order the codes were stored.
- Using a specialized scanner, you should test all of the pins in the CAN Bus harness. Before doing so, you must also install some sort of memory saving device.
- You will need to compare their findings to the manufacturer's specifications.
- In addition, you will need to test all of the control module ground circuits for continuity with the battery ground, connecting an auxiliary ground cable to help with the diagnosis.
- Now, using a digital volt/ohmmeter and a CAN Bus system wiring diagram, you need to test continuity between each individual controller, comparing their findings to the manufacturer's specifications. Additionally, you will need to test the PCM to see if the fault lies with a defective driver. Clear the P2075 trouble code and retest the system to see if it returns.
Common mistakes when diagnosing the P2079 code
In order to avoid any misdiagnosis you will need to make sure that you don’t undergo MAF sensor, barometric pressure sensor, or intake manifold tuning valve position sensor replacement without first carefully checking the intake manifold tuning valve for carbon build-up on the valve.
