Ive just done obd test with reader and its come up with "HO2S BANK 1 SEN 1" AND "HEATER CIRCUIT LOW"

Can anyone help with what that means and is it safe to drive ?

engine light came on after I went a lil quick with no fuel, engine light came on then fuel light. I thought it may have been due to low fuel but having filled up and checking code and restting it the engine light has come straight back on and same code in reader "as above"

Is it something to worry about or is it nothing and just a lil sensor of some kind ?
Need help big time......

Hi there i think its Lambda sensor(O2 Sensor),just double check,but for NewAge its 4 wire Lambda Sensor and cost in dealer about 290£ and on eBay cost around 80-90£.
P0031 HO2S Heater Control Circuit Low (Bank 1 Sensor 1)is in fact the 02 sensor and is located on the drivers side (right hand drive)before the up pipe.
Also is there a sepearate A/F sensor located elsewhere as Subaru having given me a quote for an 02 sensor and a quote for an A/F sensor part number 22641AA2
And simple question you have de-cated exhaust?

Its safe driving with this but you will be suffering with higher MPG and will run richer.
You must replace O2 sensor(Lambda Sensor),on some models working well Bosch Lambda Sensor which cost 50£,but you will be must buy 4 wire O2 sensor,for classic its 3 wire O2 sensor.No long time ago i brought from eBay for 80£(Denso) and working well and no "Check Engine Light".

Having investigated this today ive noticed its either the sensor you have to get to through right hand size wheel arch or the one on the exhaust under the car, which one would it be if you know ?
