P0030 SUBARU -

Question

What is the cost of repair for code P0030 on a Subaru Forester xs 2004 automatic transmission.

Answer 1

This code indicates a problem with the heated O2 sensor on bank 1. Bank 1 is the driver side of the engine. In most cases the heater wire inside the sensor breaks and the sensor needs to be replaced. This is the first O2 sensor in the exhaust pipe before the catalytic converter.
