Codes P2270, P103E, and P0140 all related to Bank 1 Sensor 2 O2 sensor! Replaced both O2 sensors, all four fuel injectors and dealer put in new catalytic converter. Codes still remain. Does anyone know what else this could possibly be that's causing my check engine light to turn on? What now?
Have you checked the exhaust fuse? This fuse supplies the 5 volts to the HOČ sensors.
Every minute spent angry is a happy minute lost for ever and ever!!!
