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 .

Bank one is toward the front of the vehicle. Sounds like the heated oxygen sensors have gone bad. The Oxygen Sensors are located in the exhaust pipe and require a special socket to remove and replace.

I have codes 172 & 175 (Fuel trim bank 1 & 2, running to rich) So I was told to replace the Mass Air Flow Sensor. Easy install but very expensive ($150). We'll see if the service engine light comes back on.

Listen before you spend the money try a simple thing first. At our shop we start with the EGR solenoid, locate it, remove it, make sure that the ports are clear. Carbon build can cause your symptoms

I have a 2001 Ford Focus with the codes p0136 and p0141 showing, what should I do?


both codes refer to O2 sensors. PO141 and PO136. 136 is sensor bank 1 sensor 2. 141 is bank 1 sensor 1. so this info will work on both sensors. 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).
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

Trouble code p0141-heat oxygen sensor bank1 sensor 2


Hey I had a similar problem with my '02 Focus. The problem was the actual wiring into the distributor. The wire into cylinder 1 and 3 broke (but were very difficult to see) and was giving me codes as well. Pretty common problem in that age of the focus. It made my focus hesitate and chug until the temps came up. I went to the junk yard, found a focus with a rewired module (with a heavier gauge wire), replaced it and magic. Hope that helps

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.

I have Nissan Altima 2001 running 93500 K. since last a week service engine soon light on and showing P0141 & 0325 codes. What is the fix for P0141 and P0325 error codes.


p0325 = bank 1 sensor 2 oxygen sensor p0141 = knock sensor
if it were me you could watch the sensor on a scanner to see if working properly but without a scanner i'd replace the oxygen sensor bank 1 = passenger side
sensor 2 is sensor behind the catalictic converter screwed in

good luck

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
