Back of the engine, in the exhaust above the catalytic converter. Bank 2 sensor 1 location on Passenger side, upstream. the front is called "bank 1 sensor 1" and the rear sensor is called "bank 1, sensor 2." On engine, the passenger's side bank on a forward facing engine, or the bank closest to the firewall on a transverse mounted engine, is bank number 1, so the forward sensor on that bank would be "bank 1, sensor 1." The driver's side bank(forward mount engine), or front bank(transverse engine) would be bank number 2, thus the forward sensor on that bank would be "bank 2, sensor 1," and the rearmost sensor on that bank would be "bank 2, sensor 2."
This will help. Thanks please keep updated.please do rate the solution positively .thank you for using fixya

    Bank two is the passenger side. Sensor 2 is the one that is down stream(after)of the catalytic converter.
    thanks.keep updated.

Where is oxygen sensor bank 2 sensor 2 located?

Bank 2 on a front wheel drive is the back bank. On a rear wheel drive it is the passenger side bank. Sensor 1 is located in or just after the exhaust manifold. Sensor 2 is downstream past the catalytic converter.

Hi Michael, After fixing errors you need to reset your computer by disconnecting the battery for a minute or two, Also you'll need your radio code to reset your radio, I hope this helped...........CHEERS..

What does the codes p0442,p0136 &p0141 mean on my 2001 ford taurus it failed inspection for these codes

P0442 FORD - Evaporative Emission System Leak Detected Small Leak

Possible causes- Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking
P0136 - O2 Sensor Circuit Malfunction Bank 1 Sensor 2
Possible causes- Rear Heated Oxygen Sensor Bank 1 harness is open or shorted
- Rear Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Rear Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks

P0141 FORD - O2 Heater Circuit Bank 1 Sensor 2

Possible causes- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Engine Control Module (ECM)

Your first mistake is having a "diagnosis" by a parts counter sales person.
I wrote an article about his very subject. You might find it helpful. Click the link below to read the article:

What Else Could Be Wrong?

Then, you did not list the code that you got the first time, so there is no way of knowing if the parts sales person told you correctly on the first time or not.

Diagnostic Test Code (DTC) P0058 is defined by SAE J2012 as "HO2S Heater Control Circuit High Bank 2 Sensor 2" (SAE J2012 is the standard by which all vehicle manufacturers must define the "generic" or "non-vehicle specific" diagnostic test routines necessary to properly diagnose and repair their cars.)

To understand what is going on here, it is very important to understand that this code definition DOES NOT tell you to replace the oxygen sensor. This is an oxygen sensor heater CIRCUIT code. The heater circuit on your vehicle includes the battery voltage (B+) supply circuit and the heater control (HT) circuit to the Powertrain Control Module (PCM). Failure of either of these circuits will cause DTC P0058 to set.

The B+ circuit consists of the BLACK/RED wire at the oxygen sensor connector which gets its power from the EFI 2 fuse (10 Amp) located in the engine room junction block. There are several things powered by this fuse and there are several splices and branches in the wire. Voltage MUST be checked at the O2 sensor connector.

The control circuit for the Bank 2 Sensor 2 heater is the WHITE/BLUE wire that runs only from the O2 sensor connector to connector E7 PIN #33 at the PCM.
BOTH of these circuits must be check to make sure they are not shorted to ground and that they have continuity to their connections at both ends.

Also, after repairs are made, all engine control codes must be PROPERLY cleared using an appropriate scan tool in order to make the check engine light turn off and to prevent additional problems with the engine control system. Many uneducated do-it-yourselfers will tell you to disconnect the battery cables to accomplish this. That is NOT the correct way to do it, and this can cause voltage spikes that can damage sensitive computer equipment in your car and possibly cause fault codes to set in several of the computer modules in your vehicle.

Many do not believe that this is possible. If you want proof, pull the plug on your home PC and plug it back in a few times and see if it doesn't wreck your hard drive....

P0138 and p0158

These codes, po 138 bank 1 sensor 2 shorted to voltage and code po158 means bank 2 sensor two shorted to voltage. these are the two rear oxygen sensors in the exhaust system. there two up frt and two in the rear, check the wiring on the two rear sensors, make sure that the wiring is not cut or stuck between metal. if the wiring is good then replace both rear sensors, when you get them ask for the left and right after the cat sensors. or bk1 s2 and bk2s2. after replacing them reset the computer. go to an auto parts sotre or if you have a code reader you can do it. hope this helps good day.

Check engine light on, code reads p0420

Hi and welcome to FixYa!

Code p0420 means Catalyst System Efficiency Below Threshold (Bank 1). This will surely needs attention to resolve the problem.

Hope this helps and thank you for using FixYa! Have a good one!

PO 420 This is the code that showed up. How do I check it and tell what is wrong?

P0402: Catalyst System Efficiency Below Threshold Bank 1

The ECM or PCM monitors the switching frequency ratio of heated oxygen sensors 1 and 2. A three way catalyst converter(Manifold) with high oxygen storage capacity will indicate a low switching frequency of heated oxygen sensor 2. As oxygen storage capacity decreases, the heated oxygen sensor 2 switching frequency will increase. When the frequency ratio of heated oxygen sensors 1 and 2 approaches a specified limit value, the three way catalyst (Manifold) malfunction is diagnosed.


Possible Causes:
- Three way catalyst converter Bank 2
- Exhaust tube
- Intake air leaks
- Fuel injectors may be faulty
- Fuel injector leaks
- Spark plugs may be faulty
- Improper ignition timing
- Engine Control Module

Possible Solutions:
The most common cause is the three way catalyst converter Bank 1. Changing just the O2 sensor usually doesn't repair the problem.

The code reads lean condition bank 2 it is a 6 cylinder what does that mean

This means cylinders 4 5 6 are running too lean and can be caused by a faulty co2 lambda sensor. Bank 1 are cylinders 1 2 3

Codes #171 & 174

first check out for o2 sensor if its faulty this can show up.but if its proper.Evaporative emission control system leak very small 171 System too lean (bank 1) 174 System too lean (bank 2)
