Click on the link below and follow the step by step information on how to change the O2 sensor in your Volvo. You will need a special socket that will fit over the nut of the O2 sensor connected to an extension and ratchet. Spray some WD-40 on the nut before you loosen it

They unscrew off like a spark plug does with one exception. Unplug the wiring first

How to change an oxygen sensor on a 2006 Buick rendezvous


The trouble code should tell you which 02 sensor? The 02 sensors are in the exhaust, sensor 1/sensor2, whatever, bank 1/bank2, whatever, before the cat, after the cat. You have several 02 sensors in the exhaust, don't know which one?
You should be able to remove/install with proper size wrench or deep socket. They do make an 02 sensor socket that has that slot in it, not sure if you need that, though.

Why won't my check engine light on Honda crv go off when I changed the 02 sensor?


P0134 is for #1 o2 sensor no activity. Google this for good info. Maybe you have a broken wire or bad plug. Did you inspect the plug pins going to sensor 1?

Already changed both o2 sensor


Hi again,

You'll need to check the condition of the 02 Sensor wiring and security of the connections.

1) Test the wiring for continuity

2) Test the 02 Sensors for correct factory resistance (02 sensors are very delicate and can fail if subjected to harsh knocks or being dropped).

Bank 1 o2 sensor 1999 honda accord lx v6, i need the location to change it. i can not find it in the front of my car


Bank 1 is at the back of the engine compartment next to the firewall. You'll need to know if you need to change (bank 1 sensor 1), or (bank1 sensor2). Sensor 1 is located in the exhaust system between the rear cylinder head and the catalytic converter. Sensor 2 is after the cat in the exhaust system after the cat.

My 96 nissian maxima turns off when driving down the road i try to turn the key ,lights in dash on horn blows but will not startcould it be alternater ,or what how does the 02 sensor go by functioning ...


As of 1996,all cars sold in the US were required to have an OBD-II computer interface port.
You may want to go to Advance Auto Parts, AutoZone, or Pep Boys, and get a free read
of the code(s) that you computer may be posting to help with your diagnosis.

The code coming from your vehicle's computer may be one or more of:


P0130 02 Sensor Circuit Malfunction (Bank I Sensor 1)
P0131 02 Sensor Circuit Low Voltage (Bank I Sensor I)
P0132 02 Sensor Circuit High Voltage (Bank I Sensor 1)
P0133 02 Sensor Circuit Slow Response (Bank 1 Sensor 1)
P0134 02 Sensor Circuit No Activity Detected (Bank I Sensor 1)
P0135 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0136 02 Sensor Circuit Malfunction (Bank I Sensor 2)

Note: "Bank 1" is the side of the engine with cylinder 1. "Bank 2" is the other side.

P0300 - Random/Multiple Cylinder misfire detected
P0301 - Cylinder 1 misfire detected
P0302 - Cylinder 2 misfire detected
P0303 - Cylinder 3 misfire detected
P0304 - Cylinder 4 misfire detected
P0305 - Cylinder 5 misfire detected
P0306 - Cylinder 6 misfire detected
P0307 - Cylinder 7 misfire detected
P0308 - Cylinder 8 misfire detected
P0313 - Misfire detected with low fuel


Maximas with the VE30DE and VQ30DE engines use a distributorless ignition system that is controlled by the Engine Control Module (ECM). The ECM receives a signal from the crankshaft sensor (the CPS - Crankshaft Position Sensor), and processes the signal based on inputs
from other various engine sensors, including the Oxygen sensor.
(this is the role of the O2 sensor in ECM operation).
Then the ECM sends signals to each of the individual coils in the proper firing order.
This system is more efficient than a distributor, and has fewer moving parts. The high voltage coils are directly attached to each spark plug, allowing a higher energy spark within the cylinder. A high energy spark means a faster, more thorough burning of the air/fuel mixture, which produces more power and lower emissions.


SECONDARY SPARK TEST - works for all cars, including Maxima.


1. Remove the spark plug.

2. Install the spark plug to the ignition coil/coil pack, then attach the coil wiring.

3. Ground the plug at a good ground location on the engine.

4. Crank the engine and check for spark.

5. If spark occurs, the ignition system is functioning properly.

6. If no spark exists, test the ignition coil/coil pack, power transistor and related wiring.

----------------------------------------------------------------------------------------------------------------------------
HEI Ignition Spark test - works for all cars, including Maxima.

The next level test you may want to try is a HEI (high energy ignition) spark tester kit. Cost is
about $30 at most auto parts stores. Harbor Freight Tools sells a chinese equivalent for about $16.
Place the spark tester on each of the spark plugs, and watch as the little light in the tester will
light up each time the spark plug is fired by the computer. You can actually see weak or
intermittent sparking as the motor runs - you can tell by the relative strength of the light as
you compare the intensity and duration of the light across all 6 cylinders.

If your problem were the alternator (or its built-in voltage regulator), your battery would not be
getting a proper charge, and you
wouldn't be able to start the car after a drive, since the battery would have been drained during the
drive - normally, the alternator will both charge the battery and run all electrical
features of the car during a drive.

To test your alternator, place your DMM (digital multimeter) across the battery terminals while the
car is running - it should read 13.5VDC to 14.5VDC. With the car off, you can test your battery
voltage with the same DMM - it should read 12.65 VDC (for a fully charged battery).

Alternatively, you can take your car to Advance Auto Parts, AutoZone, or Pep Boys, and they'll
attach their "charging system tester" to your car and give your car a nice test for free.
I do this with my customers' cars just to get that nifty printout of the problem. Its nice
to show a vehicle owner somethng in black & white when I'm recommending a new charging
or ignition system component (some of which can be a bit pricey).

My 2002 Nissan check engine light will not go out. I've changed the o2 sensor (Bank 1 sensor 1) could it be my computer chip?


if your getting 02 sensor code most likely the problem is not the 02 sensor you must check what code your getting if your getting a lean that could be anything else like air filter, air flow meter remember on your vehicle has 4 02 sensors I need to know what code is giving you so I can give you more advice.
