Question about 2003 Mitsubishi Montero Sport
The reason for code po154 is that there is no activity detected on the Bank 2 Sensor 1 . But there is also a bulletin that reprograms the computer for a false readout. Basically you need to monitor the O2 sensor action. If it looks in good condition then the reprogram needs to be done. If not, you need to replace the O2 sensor.
Thank you !!
