Faulty Sensors
One of the most common causes of the P2189 code is faulty sensors. This can include any of the sensors related to fuel trim, such as the mass airflow (MAF) sensor, the oxygen (O2) sensor, the throttle position (TP) sensor, and the manifold absolute pressure (MAP) sensor. If any of these sensors are not functioning properly, it can cause the system to run too lean at idle. The best way to diagnose this is to check and test the sensors and replace faulty ones.
Intake System
Another potential cause of the P2189 code is an issue with the intake system. This could include a blockage or a leak in the system, which can cause the fuel mixture to be too lean. To diagnose this, checking the intake system for any blockages or leaks is important. If any are found, they should be fixed to resolve the issue.
Fuel Pressure
In some cases, the fuel pressure can cause the P2189 code. If the fuel pressure is too low, it can cause the engine to run lean at idle. To diagnose this, it’s important to check the fuel pressure and adjust it as necessary.
Faulty PCM
The powertrain control module (PCM) can also cause the P2189 code. If the PCM is faulty, it can cause the system to run too lean at idle. In this case, it’s important to replace or reprogram the PCM to get the system running correctly again.
