i got code p0152 indication bank 2 sensor 1. wich one and where on my 97 4L?

 

Odometer reading can often help.
edit: Removed due to mistaken answer
Assuming your 24MY vehicle has average mileage (>150K?) I'd consider changing all your O2 sensors as they are cheap and degrade with use.
FYI: The left side is the driver's side ALWAYS (No. America).

 

P0152 02 Sensor Circuit High Voltage (Bank 2 Sensor 1)
P0153 02 Sensor Circuit Slow Response (Bank 2 Sensor 1)

Actually Bank 2 is Drivers side, Bank 1 is passenger side

And these codes are REPORTED by the O2 sensor, it doesn't mean the O2 sensor is bad

Yes, sensor 1 is the designation of the O2 sensors that are closest to the engine, there are 2 on a V6 engine, on the exhaust pipe next the exhaust manifold on each side

1995 and up Rangers have a 3rd O2 sensor near the muffler, called sensor 2, its there to make sure the Cat Converters are working

If you are going to change the Drivers side O2 then you should replace the Passenger side O2 as well
These do wear out, use up their chemicals, after 100k miles
The sensor 2 lasts longer, maybe 300k miles

 

Thanks for the correction. I edited my errors. Funny, I searched which bank was which before posting.
I found incorrect info....on the internet? hard to imagine.
