SOURCE: engine light on code po141 oxygen sens bank 1 sens 2

bank 1 will be whichever side cylinder 1 of your engine is and bank 2 will be the opposite side. It's named bank 1 and bank 2 so that no matter how the engine is laid out, bank 1 is always on the same side as cylinder 1. I cannot say whether the right hand or the left hand one will be bank 1 as I do not know where your cylinder 1 is. The garage should know

Codes PO141,PO403 on Olds Intrigue 1998


PO141--Oxygen Sensor Heater Malfunction (Bank 1 Sensor 2)

I would change all the O2 Sensors,when a monitor or downstream
fails,which they seldom do

PO403--EGR Circuit Malfunction

Codes Related---NO

Converter- if it is 14 years old, it is done working very well,
but not related to the heater in the oxygen sensor

I would do all the O2's,the converters & EGR Valve & go from there

I never give out that info,but look how old the car is,it won't pass
inspection, with just one of those three issues

Code P0141 and P0155


PO141 is an 02 sensor sensor heater circuit malfunction (bank 1 sensor 2)

PO155 is the same for bank 2 sensor 1.
Depending on your mileage, and no wiring problems, you will need to replace the oxygen sensors and clear the codes.

I hope this helps.

1997 blazer codes po137 po140 po141


Those codes all deal with oxygen sensor #2 (after the catalytic converter) on bank #1. P0141 deals with the heater circuit of that sensor. I would start by checking the wiring to that sensor. The sensor itself could be bad. The catalytic converter could be also bad although that wouldn't explain the code P0141.

What is that code PO141 AND PO342


Technical Description O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
What does that mean? 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).
copyscape.gif 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 codes


Hi Sandra!
The trouble codes listed are defined as:

P0141 Oxygen Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)

P0300 Random/Multiple Cylinder Misfire Detected

P0331 Knock Sensor 2 Circuit Range/Performance (Bank 2)

PO300 & PO331 are possibly symptomatic of issues caused by PO141, which would have a direct influence on the air/fuel mxture... which could cause missing and knocking.

So the first thing I would try is replacing the Bank 2 Oxygen Sensor, after making sure the wiring and connections to that sensor are in good shape.

Does the engine show any physical issues such as loosing coolant, smoking exhaust, overheating? A blown or leaking head gasket on the #2 bank could also present these (among other)
codes.

Good luck and let me know how it goes!
