OXYGEN SENSOR

2006 Buick Ranier

Engine Performance problem
2006 Buick Ranier 6 cyl Two Wheel Drive Automatic 54000 miles

Received a code of P0135 - heated oxygen sensor bank 1, sensor 1.
Where is this sensor located?
Is this something I can change (I am very comfortable working on cars)?

It's screwed into the exhaust manifold really easy to change.

HEATED OXYGEN SENSOR REPLACEMENT - POSITION 1

TOOLS REQUIRED
J 39194-B Heated Oxygen Sensor Wrench

REMOVAL PROCEDURE

NOTE:
*Refer to Heated Oxygen Sensor (HO2S) Resistance Learn Reset Notice in Service Precautions.
*Refer to Heated Oxygen and Oxygen Sensor Notice in Service Precautions.

1.Disconnect the heated oxygen sensor (HO2S) electrical connector (1).
2.Remove the HO2S (2) using a J 39194-B.

NOTE: Refer to Excessive Force and Oxygen Sensor Notice in Service Precautions.

INSTALLATION PROCEDURE

IMPORTANT: Use special anti-seize compound on the heated oxygen sensor threads. The compound consists of graphite suspended in fluid and glass beads. The graphite burns away, but the glass beads remain, making the sensor easier to remove. New service sensors already have the compound applied to the threads. If you remove an oxygen sensor and if for any reason you must install the same oxygen sensor, apply the anti-seize compound to the threads before reinstallation.

1.Coat the threads of the heated oxygen sensor with the anti-seize compound P/N 5613695, or the equivalent if necessary.
2.Install the heated oxygen sensor (2) using a J 39194-B.

NOTE: Refer to Component Fastener Tightening Notice in Service Precautions.

Tighten the HO2S to 41 N.m (30 lb ft) .

3.Connect the HO2S electrical connector (1).

Are you sure this is bank 1 sensor 1? I went to auto zone online to get the part and it shows bank 1, sensor 1 on the driver's side?

This is what Mitchell 1 is giving me Heated Oxygen Sensor (HO2S) No. 1 (4.2L) On exhaust manifold, on right side of engine.

Is your engine transverse? I'm using Mitchell 1 and Alldata auto references the professional version, don't know what Autozone is using.

Doesn't matter which side it say's it's on it's going to be in the exhaust manifold. Your engine only has one exhaust manifold so the sensor that is screwed into that manifold is going to be sensor one or aka the front o2 sensor.
