Hello,

I'm getting a P1131 - short circuit AFR sensor.

Brand new sensor.

I check the connection and the cable, all looked fine so I reset the code.

Car drove normal all day, no codes. Tonight I jumped in and started the car up and the code came up. Drove fine, no loss of power.

Any ideas? What can I do next.

Update, sensor is fixed, ie. cannot be removed but it is loose. It can be rotated, there is a lot of play. What can cause that to happen?
