P1131- lack of upstream heated oxygen sensor switch [ sensor indicates lean bank 1]

p1151-lack of upstream heated oxygen sensor switch [ sensor indicates lean bank 2]

most likely since both are showing lean I would go and clean the maf sensor with QD contact cleaner. Dont touch the wires or youll damage them. Just spray them with the cleaner. If thats not it check for a exhaust leak before the sensors.

Thanks for your reply, would you tell me where the Maf sensor is located.

The MAF sensor is the mass air flow sensor. It is located right after the air cleaner box on the air hose going to the throttle body.
