Have you checked for a vacuum leak?
Also is it 6cyl or 4cyl?
P0031-1/1 O2 SENSOR HEATER CIRCUIT LOW
P0051-2/1 O2 SENSOR HEATER CIRCUIT LOW
P0155-2/1 O2 SENSOR HEATER FAILURE
P0161-2/2 O2 SENSOR HEATER FAILURE
It sounds like you got the wrong O2 sensors. Does the engine still run?
Or you mixed up the O2 sensors
You have a code for 3 of the 4 O2 sensors the only one missing is sensor 1/2. So sensor 1/2 must be correct.
Jeep is running rough - 6 cyl
We did check for vaccum leak - the garage repair it and 2 days later the codes popped back up
I double checked and being told that they are the correct sensors. Where do we go from here
no cold air blowing out when ac is on but low pressure
