What are the probable causes of DTC P0141? - 1998 Chevrolet Lumina

P0141 = O2 Sensor Heater Circuit Bank 1 Sensor 2
this refers to one of the Oxygen sensor on the exhaust system. These sensors monitor the fuel mixture in the exhaust fumes to measure if it is running a rich or lean mixture.
This code refers to a certain sensor. Stand in front of the vehicle with the engine belts and pulleys nearest to you. the sensor your looking for is in the exhaust on the LEFT side of the engine, (Bank 1), AFTER the catalytic converter, (Sensor two).
If your fuel/air mixture is wrong or the sensor thinks it is, The engine electronics will adjust the mixture possibly causing the Sputter.
Get the sensor checked by a good mechanic.

No code tells you to replace a part , need to do diagnostic's for said code .

  • fuel contaminated by silicon additives
  • excessive oil consumption
  • glycol leaking internally in the engine
  • lead-contaminated fuel
  • short drive cycles in cold weather
  • use of unapproved cleaning agents

Is a concern present?
Yes No REPAIR the source of the contamination.

CHANGE the engine oil and oil filter.

RESET the keep alive memory (KAM). REFER to Section 2, Resetting The Keep Alive Memory (KAM) .

REPEAT the self-test. GO to DW10 .

DTC P0054 for HO2S bank 1 sensor 2
DTC P0141 for HO2S bank 1 sensor 2
DTC P0335 Crankshaft Position (CKP) Sensor Circuit

all of those codes listed have a common fault listed and that is the ECM
substitute it with a known good unit and then see what happens

Did you replace the right one ? This code does not necessarily mean the O2 sensor is bad . The code description say O2 heater " CIRCUIT " bank 1 sensor 2 Did you check the wiring , the fuse ?
P0141 - O2 Heater Circuit (Bank 1, Sensor 2) Description: See the description for DTC P0135. Possible Causes: See the possible causes for DTC P0135. Diagnostic Aids: See the diagnostic aids for DTC P0135. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test DW . P0135 - O2 Heater Circuit (Bank 1, Sensor 1) Description: During testing the heated oxygen sensor (HO2S) heaters are checked for open and short circuits and excessive current draw. The test fails when the current draw exceeds a calibrated limit or an open or short circuit is detected. Possible Causes:

• Vacuum hose disconnected on exhaust gas recirculation (EGR) system module (ESM) applications
• Short to VPWR in the harness or HO2S
• Water in the harness connector
• Open VPWR circuit
• Open GND circuit
• Low battery voltage
• Corrosion or incorrect harness connections
• Damaged HO2S heater

Diagnostic Aids: Check the HO2S electrical connector for damage, corrosion, and water intrusion.
Damaged HO2S heater. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to Pinpoint Test DW .

Yes there is something in common . Check the fuse # 79 10amp in the underhood fuse box . For O2 sensor , heater power .
The PCM commands the heater ON or OFF to maintain a specific HO2S operating temperature range. The PCM monitors the voltage on the HO2S heater low control circuit for heater fault diagnosis. If the PCM detects that the HO2S heater low control circuit voltage is not within a specified range, DTC P0030 sets for HO2S 1, or DTC P0036 sets for HO2S 2.
So this is not in spec. an it set the other codes !
If the PCM detects that the heater current or the heater calculated resistance is not within an expected range, DTC P0135 sets for HO2S 1
If the PCM detects that the heater current or the heater calculated resistance is not within an expected range, DTC P0141 sets for HO2S 2.

Diagnostic Test Code (DTC) P0141 is defined by SAE J2012 as "O2 Sensor Heater Circuit Bank 1 Sensor 2"

Most of the time, this is caused by the heating element in the O2 Sensor being burned out. However, there is a chance that there is a circuit malfunction elsewhere besides in the O2 Sensor itself.

Which Oxygen Sensor Is It?

DTC P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
This code means that the heated circuit in the oxygen sensor on bank 1 decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0141. See also: P0135 (Bank 1, Sensor 1).

You will likely notice poor fuel economy the illumination of the Check Engine Light.

Causes: A code P0141 may mean that one or more of the following has happened:
open or short to ground in the wiring harness
O2 heater circuit wiring high resistance
O2 heater element resistance is high
Internal short or open in the heater element

Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.

Possible Solutions:
Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
Repair short or open or high resistance in wiring harness or harness connectors

Hope this helps to solve it.

Sound like a DTC P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)

A code P0141 may mean that one or more of the following has happened:
* open or short to ground in the wiring harness
* O2 heater circuit wiring high resistance
* O2 heater element resistance is high
* Internal short or open in the heater element

Note: Typically a failed catalytic converter does not cause this code. You're more likely to see a P0420 code for a failed converter.

9141 does not exist I will assume it is DTC P0141 HO2S Heater Performance Bank 1 Sensor 2

The VCM has the capability to monitor this process by using the Heated Oxygen Sensor (HO2S Bank 1, Sensor 2). The HO2S (Bank 1, Sensor 2), located in the exhaust stream before the catalytic converter, produces an output signal which indicates the storage capacity of the catalyst; this in turn indicates the catalysts ability to convert the exhaust emissions effectively. If the catalyst is functioning properly, the HO2S signal will be far less active than the signal produced by the Heated Oxygen Sensor (Bank 1, Sensor 1).
When the HO2S temperature measures below 360°C (600°F), the sensor will not produce any voltage and will behave like an open circuit. This will result in an Open Loop operation.
The HO2S heater provides for a faster sensor warm-up which allows the sensor to become active in a shorter period of time and remain active during long extended idle. The DTC P0141 determines if the HO2S is functioning properly by checking the response time of the sensor. This DTC is a type B DTC.
