Trouble code help please

Recommended Posts

Hi folks, I have just bought my first car....a 2003 Fiesta with 60k on the clock, with 1.25 petrol engine. It was a private sale and within a couple of days the engine management light illuminated. My chum with a diagnostics plug said it was showing 'P0030 H02S Heater Control Circuit B1S1'. I have acquired the Haynes manual for my car and wondered could this be as simple as replacing the oxygen lambda sensor...? Thank you.
