TXR05 Member 181 Member For: 13y 10m 22d Gender: Male Location: Brisbane QLD Posted 09/12/12 07:18 AM Share Posted 09/12/12 07:18 AM So my car threw a code being p1131 lack of upstream heated oxygen sensor switch-sensor indicates lean. Any ideas on what that means? I've found quite a number of meanings about it but none for the falcon in particular. Fuel consumption has seem of gone up about 2l per 100km.

jayyraad Member 19 Member For: 12y 8m 5d Posted 09/12/12 12:47 PM Share Posted 09/12/12 12:47 PM I have same code atm. My guess was o2 sensor. Depending on if its ba or bf it has 1 or 2 sensors. Was jus gonna replace it anyway..

Kroozin Menace Donating Members 1,990 Member For: 14y 15d Gender: Male Location: Sydney Posted 09/12/12 01:37 PM Share Posted 09/12/12 01:37 PM my brother was having both 1131 and 1132 probably fixed it out of dumb luck but he contact cleaned all the connections for the sensor on the intake and zorst. Tightened all intake and zorst bolts and gapped some new plugs. I dont know which one did it, how, why or maybe it was unrelated all together but the codes are gone.
