I have several codes showing up -
P0037 - o2 sensor bank 1 sensor 2
P0057 - o2 sensor bank 2 sensor 2
P0031 - o2 sensor bank 1 sensor 1
P0051 - o2 sensor bank 2 sensor 1
P1148 - closed loop control function bank 1 sensor 1 (can’t seem to find this part? Is this another sensor or an o2 sensor?)
P0345 - cam position sensor bank 2

I find it hard to believe that all 4 o2 sensors are needed replaced at the same time, so I am trying to find out how to figure out where to start. Some of the info from googling says blown fuse, frayed wiring, heater circuit element, shorted control circuit, malfunctioning ecm/pcm.
what would y’all suggest I start at? The only issues I have had is the car shuts off when running some times but cranks back up, so I was already think it was the cam position sensor, didn’t expect all the o2 sensor codes though.

 

these 4 have to do with the O2 sensor heating circuit, check for shorted out wire and fuse..

P0037 - o2 sensor bank 1 sensor 2
P0057 - o2 sensor bank 2 sensor 2
P0031 - o2 sensor bank 1 sensor 1
P0051 - o2 sensor bank 2 sensor 1

this one means bank 1 sensor 1 O2 sensor has a connection issue, shorted out or open connection. I'm guessing this sensor has an issue causing the codes for the other O2 sensor heating element codes above.

P1148 - closed loop control function bank 1 sensor 1

bank 2 cam sensor is the cylinder bank closer to the radiator. from my experience either the sensor is bad or the connector has oil on it. the oil on the connector can be from with a valve cover leak or the sensors O-ring leaking.

the cam sensor is the only issues out of the ones you have that would cause the engine to shut off..

 

Where are the fuses for the o2 sensors?

 

it's in the fuse panel on the lower dash on the driver's side.

 

cam sensors foremost symptom is to randomly shut the car off while driving.
and how old is your car ? its def posssible to have the O2 sensors in bad shape depending, if you want to keep the car you mind as well replace the O2 sensors and 3 cam position sensors. be glad you have codes and you are not shooting in the dark.

 

I had an o2 sensor were the wire insulation was rubbed away and shorted out the fuse in the box, which then threw the four codes
P0037 - o2 sensor bank 1 sensor 2
P0057 - o2 sensor bank 2 sensor 2
P0031 - o2 sensor bank 1 sensor 1
P0051 - o2 sensor bank 2 sensor 1
I would replace the fuse only for the code to reappear after a random amount of miles.

I found the short and replaced the sensor (and the blown fuse again) so look at the wiring starting with the bank1 sensor one since that is throwing 2 codes at this point.
