I have a P0058 code after backing onto a snow bank

https://www.obd-codes.com/p0058

Bank 2 is the front of the engine ( closest side to the grill) and sensor 2 is after the catalytic converter.

code p 0058 refers to heated oxygen sensor (HO2S) 2 bank 2-heater control--circuit high === causes --wiring short to positive ---HO2S--ECM
for your previous post code p 0038 refers ti the HO2S 2 bank 1 heater control circuit high ===the causes are the same

Bank 2 sensor 2. This means the passenger side down the stream behind the catalytic converter

following answer courtesy of OBD-CODES,com P0058 HO2S Heater Control Circuit High (Bank 2 Sensor 2) OBD-II Trouble Code Technical Description Article by Dale Dale Toalston ASE Certified Technician Generic: HO2S Heater Control Circuit High (Bank 2 Sensor 2) Nissan: Heated oxygen sensor (HO2S) 2 Bank 2 - heater voltage high What does that mean? This code is a generic powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may be slightly different depending on the model. Oxygen sensors with a heating element are common on today's engines. Heated Oxygen sensors (HO2S) are inputs used by the PCM (Powertrain Control Module) to determine oxygen content in the exhaust system. The PCM uses the information gained from the Bank 2,2 HO2S mainly to monitor the efficiency of the catalytic converter. Integral to this sensor is a heater element. While in pre-OBD II vehicles an Oxygen sensor was a one wire sensor, now they are more commonly 4 wire sensors: Two dedicated to the oxygen sensor and two dedicated to the heater element. The oxygen sensor heater basically decreases the time needed to achieve closed loop. The PCM controls the heater on-time. The PCM also continuously monitors the heater circuits for abnormal voltages or in some cases, even abnormal amperages. Depending on the make of vehicle, the Oxygen sensor heater is controlled one of two ways. (1) The PCM directly controls the voltage feed to the heater either directly or via a HO2S relay and a ground is supplied from the vehicle's common ground. (2) There is a fused 12 volt Battery feed (B+) that feeds 12 volts to the heater element anytime the ignition is on and the control of the heater is done by a driver in the PCM which controls the ground side of the heater circuit. Finding out which one you have is important because the PCM activates the heater under various circumstances. If the PCM detects an abnormally high voltage condition on the heater circuit, P0058 may set. This code is only referring to the heating circuitry half of the Oxygen sensor. Bank 2 is the side of the engine that does not contain cylinder #1. Symptoms Symptoms of a P0058 DTC may include: MIL (Malfunction indicator lamp) illumination There would likely be no other symptoms. Causes Potential causes of a P0058 code include: Faulty Bank 2,2 HO2S (Heated Oxygen sensor) Open in the heater control circuit (12 volt PCM controlled systems) Short to B+ (battery voltage) in the heater control circuit (12 volt PCM controlled systems) Open ground circuit (12 volt PCM controlled systems) Short to ground on heater control circuit (On PCM ground controlled systems) Possible Solutions First, do a visual inspection of the Bank 2, 2 HO2S (heated oxygen sensor) and it's wiring harness. If there is any damage to the sensor or any damage to the wiring, fix it as needed. Check for bare wires where wiring enters sensor. This often can fatigue and cause shorts. Make sure wiring is routed away from exhaust. Repair wiring or replace sensor as necessary If all appears okay, unplug the Bank 2,2 HO2S and verify that there is 12 volts B+ present with the key on engine off, (or ground is present, depending on the system). Verify the heater control (ground) circuit is intact. If so, remove the o2 sensor and inspect for damage. If you have access to resistance specifications you can use a Ohmmeter to perform a resistance test of the heater element. In

Hi there:
You are right, DTC P0058 - HO2S Heater Circuit High Voltage Bank 2 Sensor 2

As far as replacing them, the only thing that has me wondering about a wiring issue. Keep in mind that power comes directly from the engine computer. Either the wires are broken or the computer is bad.

Aditionally, in THIS LINK could fin other descrtipion test and details procedure.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

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....

Has something to do with your relay. I have searched through all my manuals and cannot find anything else about it. But you will need to replace a O2 sensor
