Code po141 heater circut sensor/where do i find this sensor? where is bank 1

Here's a link for codes P0446,P0443. https://www.obd-codes.com/p0446 Here's the link for P0403. P0403 Exhaust gas recirculation EGR circuit malfunction Here's code P0135 P0135 OBD II Trouble Code O2 Sensor Heater Circuit Malfunction Bank 1... Here's code P0141 P0141 OBD II Trouble Code O2 Sensor Heater Circuit Malfunction Bank 1... Here's code P0155. P0155 OBD II Trouble Code 02 Sensor Heater Circuit Malfunction Bank 2... Here's the last code.yay P0161. P0161 OBD II Trouble Code HO2S Heater Circuit Malfunction Bank 2 Sensor 2... The last 3 codes might just be one sensor.

P0455: Evaporative Emission Control System Leak Detected Gross Leak 1
P0455 Evaporative Emission Control System Leak Detected Gross Leak

P0141: O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 2
P0141 O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 2

Trouble Code: P0141

HO2S-21 (Bank 1 Sensor 1) Heater Circuit Malfunction

Possible Causes:


HO2S heater control circuit is open or shorted to ground.
HO2S heater power circuit open between the heater and PCM.HO2S heater is damaged or has failed.PCM has failed (it controls the heater with a duty cycle signal).The sensor is on the passenger side,that is cylinder number one.

Change the O2 sensor.

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.

po141, may be a bad o2 sensor, rear sensor after converter. the po 141 is low voltage to tps, try replacing the oyxgen sensor first and then reset the codes and drive if the po141 comes back then replace the tps,

P0141 - Heated Oxygen Sensor (HO2S) Heater Performance Bank 1 Sensor 2

HI, this code if for a fouled O2 sensor that you will need to replace asap.

P0135--OXY SENSOR HEATER CIRCUIT(bank 1 sensor 1)
P0141--OXY SENSOR HEATER CIRCUIT(bank 1 sensor 2)
P0155--HEATED OXY SENSOR HEATER CIRCUIT(bank 2 sensor 1)
P0161--HEATED OXY SENSOR HEATER CIRCUIT(bank 2 sensor 2)
P01132--LACK OF HO2S11 SWITCH--SENSOR INDICATES RICH
P01152--LACK OF HO2S21 SWITCH--SENSOR INDICATES RICH

Here are the code definitions.hope it helps.

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!
