P0057 - 2005 Jeep Wrangler

changed the wrong sensors
the code (p0057)refers to the heated oxygen sensor (HO2S) which is in the exhaust manifold before the cat converter
code p 0172 refers to system too rich bank bank 1===causes ---intake blocked ---EVAP canister purge valve --- fuel pressure---EGR systems ---injector/s---HO2S
If you replace the HO2S sensor/s then that will [robably fix all codes
the heated oxygen sensor reads the exhayst gas and reports to the ECM to adjust the air /fuel ratio to get the engine to run within parameters
when it is not working , it runs lean or rich

Replace the power steering pressure sensor. replace both the O2 sensors.

the engine managment system on this car treats each bank as 2 seperate engines bank 1 and bank 2 the fault codes you have got are emission related. diagnosis is not easy because the ecu will use the other bank to compensate and alter its fueling etc to reduce emissions. the only way to sort it out is to put it on suitable diagnostic equipment and monitor live data ie. lambda sensors/ catalyst efficiency hope this helps

I GOT the code:
PO 030 "heather control" bank 1 med sensor 1
This is on a BMW 2003model 316i

Do know which sensor this is?

Is IT the oxygen sensor on the catalysator or the temperature sensor on the engine?

Get a scanner and have a ck

Bank 2 is down on the exhaust past the catalytic converter

P0057 Definition: O2 Sensor heater circuit low- 22
Probable causes:
1. Open or short circuit condition
2. Open fuse
3. Failed HO2S 11 (i.e., bad O2 Sensor).

Got this off the Jaguar Forums.com for you.
