No engine options (size) stated so... bad answers happen.......????
p0141 (federal code) is
P0141 Jeep - O2 Sensor 1/2 Heater Performance http://engine-codes.com/p0141_jeep.html

in bar stool , answer:
the heater is toast, (pun intended)
the heater burned up and open or is shorted.
Or as techs know>
bank 1 sensor 2 , rear , is bad or the wires cut or shorted there.
the Computer ONLY knows that test fails, NEVER why
and is never wrong.
the current is wrong. (amps)

P0141 code for 1997dodge truck 5.9


Always clear the code and see if it comes back first. Especially with an O2 sensor code.

The truck stalled out when driving. Sounds like it wants to start, but won't fire. Codes found - P0410, P0128, P0141, P0102. Please help. Daughter's truck and she leaves for college in a few days.


code p0410 refers to secondary injection system--malfunction===causes wiring--air valve--air solenoid--- ECM
code p0141 refers to heated oxygen sensor-2 bank1-heater control -circuit malfunction===causes --wiring--oxygen sensor--ECM
code p0128 refers to coolant thermostat --coolant temp below thermostat regulating temperature==causes mechanical fault (thermostat stuck open)
code p0102 refers to mass air flow (MAF) sensor/ volume air flow (VAF) sensor low input===causes wiring short to ground--MAF/VAF sensor ECM

What do you mean the code PO141 on subaru forest 1999?


code p0141 refers to heated oxygen sensor-2 bank1 heater control-circuit malfunction ===causes --wiring--Heated oxy sensor---ECM I would replace the sensor first and see it that fixes the fault. remember to use a code reader to reset the cpu or else the fault will reappear.

Engine code p0141


Code p0141 indicates heated oxygen sensor (HO2S) 2 bank 1 heater control - circuit malfunction possible causes Wiring----HO2S and ECM I would replace the sensor with a genuone one as the parameters for non genuine may be different and give you the same fault code

Error codes p0141 on ford windstar 2002


Hi there:


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).



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.

MY 04 CHEVY TRAILBLZER HAS CODES P0526 P0141 P2135 P2138


Four seemingly unrelated fault codes;
P0526 - fan speed error
P0141 - downstream O2 sensor lean condition
P2135 - Throttle position sensor fault
P2138 - Accelerator position fault

You need to have a qualified technician diagnose this with a highend scan tool, maybe there is a possibility that a reference voltage is off spec.

What is diagnostic procedures for DTC p0135 & p0141


Oxygen Sensor problems... P0135 (Bank 1, Sensor 1) and P0141 (Bank 1, Sensor 2)

P0135 - Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
This code refers to the front oxygen sensor on Bank 1. The heated circuit in the oxygen sensor 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 P0135.

Symptoms: You will likely notice poor fuel economy the illumination of the MIL.

Causes: A code P0135 may mean that one or more of the following has happened:
O2 Heater element resistance is high
Internal short or open in the heater element
O2 heater circuit wiring high resistance
open or short to ground in the wiring harness

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



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.

Symptoms: 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
