hi my mate just bought a my03 wrx, the car seems to run very fine except the managment light is on after diognostic, this has come up h02s heater control circuit low, bank sensor1,dtc=p0031, wondering has anyone ells had the same problem will it damage the block or efect in driving, cure for the problem would be great.

thanks

 

Hi there probably your Lambda sensor is knackered/damaged,best bet is buy new one Denso on eBay cost around £88-£100(from dealer cost £300)
