In my 1990-1995 manual it is Black/Dark Green.

Dark green/orange is 12 V supply, Black is ground, Black/Light Blue also comes from the powertrain control module but is common to many other sensors.

How to fix error code P0153 Slow Response Bank 2 Sensor


This involves the oxygen sensor upstream the catalytic converter on Bank 2. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use. You will likely not notice any drive ability problems, although there may be symptoms. A code P0153 may mean that one or more of the following has happened: The oxygen sensor is faulty The wiring to the sensor is broken / frayed There is an exhaust leak Possible Solutions Things that may fix the problem include: Check and fix any exhaust leaks, Check for wiring problems (shorted, frayed wires), Check the frequency and amplitude of the oxygen sensor (advanced), Check for a deteriorating / contaminated oxygen sensor, replace if necessary, Check for inlet air leaks, Check the MAF sensor (sensor of the pipe from air cleaner) for proper operation, Replace the Bank 2 oxygen sensor upstream of the catalytic converter (follow from CC towards engine - you wil see the sensor)

Description:
Oxygen Sensor (O2S) 1, Bank 1/Heated Oxygen Sensor (HO2S) 1, Bank 1 - No Activity Detected
Possible Causes:
- Wiring.
- Signal wire between the Heated Oxygen sensor and ECM is disconnected.
- Heated Oxygen Sensor defective.
- ECM.

I am looking for the oxygen sensor in the 2003 Rav 4 toyota.


you will find the oxygen sensor on the pipe after the cataletic converter
it looks like a spark plug with a long wire on it its going to come out hard
you will need a goog 13/16 wrinch 6 sided works best make sure the battery
is unkooked in stall the new one hook up the new wire rehook the battery
and restart the computer will have allready reset it self from the battery
hu hooked that resets the computer ther new oxy.sensor will start reading
corectly and your proublam is fixed thank you bob

Lambda oxy sensor def. Will Denso work


Yes, the Denso Mfr #: 234-4209 O2 sensor is a universal 4 wire pre cat sensor that will work in your vehicle. Bosch also makes an exact fit sensor, #15606 for the upstream & 15607 for downstream.

Need a new po135 - 02 heater circuit


UPSTREAM OXYGEN SENSOR
The oxygen sensor is installed in the exhaust manifold Upstream Heated Oxygen Sensor - 2.4L. or Upstream Heated Oxygen Sensor - 3.0L. or Upstream Heated Oxygen Sensor - 3.3/3.8L .

CAUTION: Do not pull on the oxygen sensor wire when unplugging the electrical connector.

WARNING: THE EXHAUST MANIFOLD AND CATALYTIC CONVERTER MAY BE EXTREMELY HOT. USE CARE WHEN SERVICING THE OXYGEN SENSOR.

REMOVAL
Raise and support vehicle.
Unplug oxygen sensor electrical connector.
Use a socket such as Snap-On YA8875 or equivalent to remove sensor.
When the sensor is removed, the exhaust manifold threads must be cleaned with an 18 mm X 1.5 + 6E tap. If using original sensor, coat the threads with Loctite 771-64 anti-seize compound or equivalent.
INSTALLATION
Reverse removal procedure to install a new sensor
New sensors are packaged with compound on the threads and no additional compound is required. The sensor must be tightened to 27 N·m (20 ft. lbs.) torque

OXYGEN SENSOR ID


Only way to tell is count the number of wires coming from it. You also need to know if its the right or left bank and upstream or down stream. Upstream is before cat converters and by or in exhaust manifolds, down stream is behind converters and only measures converter effeciancy.

Wiring


2002 PCED OBDII-Villager SECTION 1: Description and Operation Catalyst and Exhaust System Overview The catalytic converter and exhaust system work together to control the release of harmful engine exhaust emissions into the atmosphere. The engine exhaust gas consists mainly of nitrogen, carbon dioxide and water vapor. However, it also contains carbon monoxide, oxides of nitrogen, hydrogen, and various unburned hydrocarbons. Carbon monoxide, oxides of nitrogen, and hydrocarbons are major air pollutants, and emission into the atmosphere must be controlled.
The exhaust system consists of an exhaust manifold combined with a pre-catalytic converter, upstream heated oxygen sensor (HO2S11), (located just in front of the pre-catalytic converter), three way catalytic converter (TWC), downstream heated oxygen sensor (HO2S12) (located in front of the TWC), a muffler and an exhaust tailpipe.
Heated Oxygen Sensors The Villager is equipped with both upstream and downstream heated oxygen sensors (HO2S) (Figure 1). The upstream heated oxygen sensor (HO2S11) is used to control engine fuel flow. The sensor detects the concentration of oxygen in the exhaust gas and sends a signal to the powertrain control module (PCM). In a rich condition, the HO2S will output a voltage of 0.6 volts or greater, and in a lean condition a voltage of 0.4 volts or less will be output.
The downstream heated oxygen sensor (HO2S12) is used primarily for monitoring the efficiency of the catalytic converter system. The HO2S12 works in a similar way to the HO2S11 but only indicates to the PCM that the catalyst is functioning properly. In the event that the HO2S11 fails, fuel control will be switched over to the HO2S12 and the malfunction indicator lamp (MIL) will be illuminated. This allows the vehicle to operate with fewer emissions, even with a sensor failure.

I took my car to autozone to get the OBDII code. He said it was a O2 sensore but did not know which one? Also is it a 2 wire or 3 wire O2 Sensor for a 1996 850 Turbo?


When the codes are read they generally have an identifying number for the Oxygen sensors. For instance: "B1S1" This means" exhaust bank one, sensor one. THe first sensor of your first bank.

Your VOLVO 850 is an inline 5-cylinder, so it has just one exhaust bank I believe. So it should have an Oxy sensor upstream and one downstream of the catalytic converter. The upstream one is sensing lean/rich condition of your just-burned fuel mixture, while the downstream one measures efficiency of your catalytic converter. I suggest you go somewhere else to have the car checked and scanned. Nothing against the parts dealers, but those guys are barely cashiers, as you found out. It was free right? Worth just what you paid for it, nothing!!! Maintain your Volvo so it will take care of you for years to come.
