SOURCE: Oxygen sensor replacement

It's something you can with simple tools, you have four O2 sensors. Your going to have to get the truck rescanned or if you have the DTC code, you can find out which O2 sensor has gone bad so you can replace it. Your going to have Two upstream O2 sensors on each exhaust bank, one O2 sensor before the Catalytic Converter, and the last one after the Catalytic Converter. Its like replacing a Spark plug and you can pick up the O2 sensor at any large Auto Parts store with a can of WD 40. Just unclip the wire leads to the O2 sensor and then with a O2 sensor socket or hint close end wrench and hammer, you can remove the O2 sensor from the exhaust pipe. Good luck and be safe.

SOURCE: Check engine light came on

My book says ( GM ) P1133 - HO2S/O2S Insufficient Switching Sensor 1 Or Bank 1 Sensor 1
Be that as it may - to clear the codes in your computer - disconnect the battery for a couple of minutes and see if that clears the codes. Let me know. Thanks

SOURCE: Have trouble code 45 on

1994 Chevrolet S10 Blazer 4.3L, Vin W Customer Concern: DTC 45 The spark plugs are black on both banks. Right bank plugs are damp. Removed the tuning valve and looked inside the plenum. Can see a washed/clean area on the right side. Fuel pressure is good, it holds when the pump stops. Tests/Procedures: 1. Remove the upper intake plenum cover and inspect for a fuel leak at the fuel pressure regulator.

2. Inspect the fuel pressure regulator and return lines and fittings at the left side of the plenum.

3 Replace the Central Multipoint Fuel Injection (CMFI) unit. Potential Causes: Leaking Fuel Line - One or more may have a problem.
Leaking Fuel Pressure Regulator
Tech Tips: The fuel pressure regulator may only leak at a cold or hot engine, only with vacuum applied, or only without vacuum applied. The leaking at the fuel lines and fittings have as often been the result of repairs as the initial cause of the problem. Handle the lines and fittings carefully. The fuel pressure regulator is a integral part of the Central Multi-port Fuel Injection (CMFI) unit. Any failure requires entire unit replacement.

SOURCE: What does the oxygen sensors look like in a 2003

There should be an O2 sensor before and after the catalytic converter on your vehicle, so it will have 2 sensors. You'll need a 7/8" open end wrench or an O2 sensor socket to replace them.

It'll look something like this: http://www.carsteering.com/data/all_images/48-01718.jpg

SOURCE: check engine light on because of oxygen sensor on

Before to change other sensor or parts, I suggest scanned the PCM (Powertrain Control Module) to know exactly what fault code is stored there ans causing engine light turn on. With this code number we could send other details.

Some Autozone or Autoshop with OBD scanner readers make this job for free.

Hope this helps, keep us updated and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa.

PO-139 I had that sensor change 3 weeks ago and the check engine light came on again this morning.Thanks


Probably replaced a good sensor. This codes could be from a bad sensor, a vacuum leak, or an exhaust leak before the sensor.

OXYGEN SENSORS REPLACED, ENGINE LIGHT STILL ON


Check Light & Codes for What?

You look up the codes,diagnose the system
the codes point to

I don't know what codes you had or why the O2
Sensors were replaced

Codes don't tell you to replace anything

Have you not gone to a repair shop to have
whatever the problems are properly solved?

Hello! No, I disagree...The warning light is the Check Engine Light (CEL)...When it comes on it is the computer telling you that a trouble code/codes have been stored...There is a lengthy list of codes...Take the vehicle to an auto parts store and have them run a scan (done for free) to find the code that is setting the warning light...Oxygen sensors as well as many, many other sensors will set a trouble code if faulty...There are 4 Oxygen sensors not 2 on your vehicle...In many instances the O2 sensor fault is an effect not a cause...Lets find out what the trouble code is before jumping to an expensive conclusion...Send a comment when you have the code...Guru...saailer

Replaced the O2 sensor unit and the ECM(programs installed) but I'm still getting CHECK ENGINE LIGHT(P0001). what is the possible problem and how can this be resolved?


P0001 Fuel Volume Regulator Control Circuit/Open The above code is about an oxygen sensor code for the heater circuit located in bank 1 sensor 1. (bank 1 is at exhaust manifold by the #1 cylinder head, bank 2 is on the 2nd cylinder head. On some engines, both exhaust manifolds could have one oxygen sensor each side and the 2nd cylinder head will have the sensor 2). On the oxygen sensor itself, it has 4 wires which are color coded. Two of wires are for the heater circuit that heats the oxygen sensor to make it reach optimum operation quickly. Those 2 oxygen sensor heater wires could be shorted between the sensor and the ecm (engine computer) or other engine components.
oxygen%20sensor%20heater%20copy.jpgThe common fix for this code is to check the integrity of the heater wires. Check the wires for insulation and routing which could be loose or touching a hot exhaust that can short the wires. If the engine has too many miles, it is possible that the heater circuit inside is worn and shorted which needs a replacement of the oxygen sensor. If you have a DVOM, you can also test the continuity of the heater wires from the oxygen sensor to your computer pins.
More detailed fixes will be provided as soon as you give the symptoms of the obd2 trouble code. ATS will provide the wiring diagram so you can trace the color coded wires. Use an obd2 code reader or scanner so you can access this obd2 trouble code. When you have this obd2 code list, use it as a reference and give the code to ATS. We will then send you all the possible fixes for the obd2 trouble code. ATS has lots of fixes for obd2 gm codes, obd2 ford codes, dodge obd2 codes and all obd2 import codes such as Toyota obd2 codes, Honda obd2 codes, Nissan obd2 codes, etc. All fixes for this obd2 codes are guaranteed or your money back.
Important TIPS about Oxygen sensor:
The oxygen sensor content of the exhaust gas indicates when the engine mixture is operating lean or rich. When the oxygen sensor detects that the engine is operating rich, the signal voltage is high, and any decreases in the signal voltage means the engine running is lean. The engine computer supplies a reference voltage like one volt or five volts, and then shows the change in the sensor return voltage as the sensor's resistance is changing. If you have connected everything properly, when you crank the engine, you should see the check engine light coming out.
Unheated oxygen sensors rely on the heat of the exhaust gases to reach the working temperature, therefore they might start to cool down while the engine is idling and revert back to a default air-fuel ratio setting. This type of sensor usually has a single wire connector, though others have two. Unlike the fuel pump relay, the 02 sensor heater circuits have a separate fuse for each sensor and grounds, which are controlled by the engine computer.
To read a voltage across the heater, one side must be connected to (+) and one side must be connected to (-), which is accomplished by the computer or a transistor. It can read 12V between each wire and a separate ground if it was connected to positive and the other was not yet connected to ground connection (for details, please contact ATS).after you replace oxygen sensor you have to drive for so many miles before it resets its sef

Trouble codes


Dear Sir/Madam:

What this code actually means is that the oxygen sensor is not switching fast enough. If you have a scanner where you can see the voltage of the oxygen sensor; you should notice it switching from like .2 to .8 volts very quickly in a properly functioning sensor. Without even looking at the vehicle; I'm over 95% sure that this is the case with your automobile and that the oxygen sensor should be replaced.

Bank 1 sensor 2. Oxygen sensor heater control circuit high. You can try disconnecting at connector to sensor, clean connection good, disconnect battery for a minute or so & retry. If it comes back, I'd look at replacing heater solenoid.

Engin light ON


Start with the evap valve first. However, the bad exhaust could have damaged your oxygen sensor. If you still get the trouble code on the oxygen sensor, replace it second.

Check engine light


P0041 Downstream Oxygen Sensors Swapped From Bank To Bank
How does a P0041 code trigger the check engine light? This code will trigger the light to come on under the following condition:

The Heated Oxygen Sensor Monitor, a strategy built into the computer, determines if the Heated Oxygen Sensor (HO2S) signal response for a change in fuel trim corresponds to the correct engine bank. If a response from the Oxygen Sensor being tested is not indicated, a trouble code will be set and the MIL (Malfunction Indicator Lamp) will illuminate.
Possible Causes:
Crossed Heated Oxygen Sensor harness connectors
Wiring swapped from one Oxygen Sensor connector to the other
Wiring changed at the computer connection or in the related harness
