Changed ecm now get p0058 code - 2007 Jeep Liberty Sport

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

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

The transmission valve body will need to be replaced ,

The P0058 is set when the ECM detects an excessively high voltage through the heated oxygen sensor heater circuit

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.

This vehicle is equiped with 2 O2 sensors 1 is before the Cat converter and 1 after the Cat converter this code is for the 1 after the Cat converter or the most rear sensor not the first 1 change the farthest one from the engine and your problem should be solved.
