This is the sensor downstream, near the transmission. This is the more difficult of the two only because of the location of the wiring. It's wired into a plug near the top of the tranny, but not too bad. The one upstream, in the engine compartment is in plain view when leaning over the passenger side fender. You can rent a special 02 sensor socket, has a slot on the side of it for the wiring. Other than that, their both pretty straight forward. Don't forget to put a small amount of anti-size for future work.

ENGINE LIGHT ON CODES P0141 & P0144


code p 0141 refers to heated oxygen sensor (HO2S) 2 bank 1--heater control--circuit malfunction===causes --wiring---HO2S--- ECM
code p 0144 refers to heated oxygen sensor(HO2S) 3 bank 1--high voltage ===causes wiring short to positive ---HO2S---ECM
also refers to oxygen sensor(O2S) 3 bank 1--high voltage ===causes wiring short to positive---O2S-- ECM
HO2S sensors are the units in the exhaust manifolds or before the cat converters
O2 sensors are after the cat converter
two completely different operations
use the special tool for sensors as the wires are easily damaged from the wrong tool use
as for misfiring you will get a P0300 (0300,0301,0302,0303 etc) depending on which cylinders are misfiring
when checking for misfiring the injectors , (blocked or not firing) are as important as plugs and wires
If the misfiring continues after sensor replacement , replace the ECM with a known good one as it is common to all fault codes and misfiring

If I'm receiving the code stating Heater Control Sensor 2 Bank 1, but I've verified the wires are correct on the 02sensor. What is another possible problem?


o2 sensor id fai;led and needs replacing
the heater control is for the HO2S sensor which is different to the O2 sensor
the heater control sensor (HO2S) is before the cat converter and the O2 sensor is after the cat converter
because you have bank 1 then there are 2 HO2S sensors and 2 O2 sensors

How to Diagnose a P0135 -Heater
Performance Bank 1 Sensor 1 (GM 3.5L)
January 31, 2012 Updated: October 29, 2014 Written by: Abraham Torres-Arredondo Article Id: 371

image_1.gifIf your check engine light is on and you have a diagnostic trouble code P0135 stored in the PCM's memory... then you've come to the right place to test and troubleshoot the upstream oxygen sensor.
A P0135 DTC says: HO2S Heater Performance Bank 1 Sensor 1... and this means that the PCM (Powertrain Control Module = Fuel Injection Computer) has detected a problem with the front oxygen sensor's heater element or a problem in the heater's circuit (wires).
In this tutorial, I'll show you how to check the oxygen (O2) sensor's heater element and the two circuits that feed it with power (10 to 12 Volts) and ground with a multimeter.
In case you're wondering, where the oxygen (O2) sensor that the code P0135 is accusing of being BAD is... this bad boy is located on the exhaust manifold and before the catalytic converter.
To help you navigate this article, here are its main points:
  1. Symptoms of a BAD Oxygen Sensor Heater Element.
  2. What Tools Do I Need to Test Code P0135?
  3. What Does the Heater Inside the Oxygen Sensor Do?
  4. Circuit Descriptions of the Downstream Oxygen Sensor.
  5. Start Here.
  6. TEST 1: Oxygen Sensor Bank 1 Sensor 1 Test.
  7. TEST 2: Checking 12 Volts to O2 Heater.
  8. TEST 3: Checking the O2 Heater's Ground Circuit.
  9. TEST 4: Ohming the O2 Heater Element.
  10. P0135 O2 Sensor Heater Test Summary.

    Engine Light on --Scaning appeare Code 0141


    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).

    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

    Hope helps (remember to rate this answer).

    Error code p0032 on 2004 dodge caravan. what is the code?


    Hi.

    P0032 means HO2S Heater Control Circuit High (Bank 1 Sensor 1).

    It means high impedance from O2 sensor, check wiring to sensor and replace the sensor.
    Check O2 sensor located in bank 1 (cylinder 1 side- see here), and after the catalitic converter (there is also an O2 sensor before cat converter).
