SCT Codes - HELP?

[shb5007]

Using this "down time" to check out a few things on the Cobra. Car is running fine, but have been getting these codes off and on. Any tips of where to look? What to do?

Hard to see pictures but

Po for 02 sensor.

Chilton Library

Diagnosis in here has code charts to follow.

Sorry. Codes are...

P0152 - o2 (ho2s-21) ckt high voltage (b2, s1)

P2197 - o2 sensor signal biased / stuck lean (b2, s1)

Thanks!

Drivers side front 02 is bad

You can confirm with swapping fronts side to side.

Codes will follow if o2 is bad.
And be bank 1 sen 1

It’s common

I like to do mine in pairs.

They to me are like a light switch

On/off

Sounds good. Ordering (2) NTK sensors today. Will replace and then update the thread, just for others in the future.

Replaced both upstream sensors and code is gone. Thanks everyone!
