oxygen sensor replacement?

The do different jobs, they do look the same but they are not interchangeable. Here is a guide to help you change them out with instructions in the diagrams below for your car.

Check out the diagrams (Below). Please let us know what happens.

so i need to remove the oxygen to the the right place are that what you saying?

The up stream and down stream o2 sensors are not interchangeable, if you have replaced one because of failure you do not have to change the other at the same time, if it is working, do not touch it. you just can't put them in front to back positions that's all.

how to put on o2 sesnsor on a 1999 ford truck

See my profile....They screw in just like a spark plug.

However they have a wire to contend with, so they make a O2 tool, basically a spark plug socket with a cut-out down the side, for the wire to protrude out.

For hard to get to spots, other specialty sockets are available........Sometimes you can do it with a wrench or channel lock pliers.

Since I know little about your rig, I do not know how many you have and their locations. They are usually on the mandifold or exaust... close to the engine...or...around the catylitic converter A manual would be a good investment.

When you purchase the O2, the part store guys are good about FREE CODING and which one ...and where.

Please send back your results.

Engine Mechanical problem
1998 Ford F150 V8 Four Wheel Drive Automatic

getting a diagnostic of both oxygen sensors on drivers side changed them an reset the codes still the same thing were should i start troubleshootin

What codes did you get? P0171 or 174? If so check for vacuum leaks, and fuel pressure. https://www.2carpros.com/car_repair_video/test_fuel_injection_pressure.htm Go here and checkout our video. You can rent the test gauge at Autozone. Get a can of spray gumout, spray the vac lines and maniflod area, when the idle changes, youve found the leak! You want the engine running and spray on the outside but do direct the stream onto the hoses, if it is a vacuum leak, the engine idle will change speed, then you have detected a leak, repair the vacuum leak and see how it runs!

Just replaced both heated o2 sensors on it an still get codes P0135 and P0155. is it possible to buy bad o2 sensors?

Hello,

In the diagrams down below I have included a diagnostic troubleshooting flowchart from the vehicle manufacturer for both Direct Trouble Code (DTC)(s) P0135 and P0155. These flowcharts will lead you to the exact cause of the DTC(s) so you can get it fixed, and fixed right the first time.
Please go through these guides and get back to us with what you are able to find out.

Thanks,

Is it possible that a bad PMC relay would cause codes P0135 and P0155?

Hello again,

It's possible, but extremely unlikely. The troubleshooting guide that was sent to you earlier is what the technicians at a dealership would use to diagnose your vehicle for these DTC's. I would follow the guide and you should find the cause.

Thanks,

If I can jump in here, those codes are for the O2 heaters. I would check the heater wiring and ground and if okay replace the PCM. Here is a guide and the engine wiring diagrams to help confirm the failure. We had this problem on a 2005 Crown Victoria and it was the PCM.

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

i have a ford f150 1998 i was wondering if the oxygen sensors make it sputter like it wants to stall when your in drive and sitting at a light or in traffic. it runs fine when it is in nuetral or park it only happenes when your sittin in drive. thanks for help.

yes they could among many other things. if the o2 is faulty and detects a high fuel mixture but its actually normal and it turns down the fuel mixture it would run to lean causing that problem.

easiest way to find out is to scan for trouble codes.

I was getting heater and circuit malfunctions for the O2 sensors. I then replaced all the sensors cleared the codes and the codes were back again after two trps in the truck. Any idea what could be going on?

Did you check wiring, plugs... Many times, due to the heat, the wiring to the O2 sensors gets damaged.

Let me know. Also, let me know the code you get.

Wiring seems ok its hard to tell because the drivers side O2 sensor plug is in a tight sport. The codes are 136 and 141. I get two codes 136 and 141 then two more with the same number that say pending. when i replaced the sensor it looked like it had overheated half of the sensor was white and inside it looked cracked.

Have you replaced them more than once?

No this is the first time

I wonder if you got a bad one that shorted.

thanks, I guess thats possible. I will have to pull it and see if it looks overheated again. If it over heated again what could cause that?

A really lean mixture, bad converter...

Thank you. Where is the converter located and would it just need to be replaced?

The catalytic converter is part of the exhaust system. Make sure it is bad before replacing it. Check to see if gets red hot when running the car.

Let me know what you find.

I have a 1997 f-150 128,000 miles on it.... 4.2 v-6 engine manual 5 sp transmission...
I had a check engine light come on about 3 weeks ago.... and took to auto zone... code said bank one sensor one 02 sensor was bad and I replaced it....
truck seemed to run ok if anything better

then I got check engine light again about two weeks later and have five codes repeated twice....p0135 bank 1 sensor 1 sensor heater circuit malfunction, p0141 bank1 sensor 2 heater circuit malfunction, p0153 o2 sensor CKT slow response, p0155 O2 sensor heater circuit malfunction bank2 sensor 1, p0161 O2 sensor heater circuit malfunction bank2 sensor 2, p1152 HO2S bank 2 s 1 insuff switching rich mean, then all these same codes are listed again in the same order...

If I have these codes cleared and drive the truck when the truck is warmed up(like home from having them checked)... it does not set these codes.... until.... the truck sits and cools off and I start it again.....
then all these same codes appear....

The truck seems to start and run fine.... I do not notice any difference from the way it was running before the Check engine light started coming on... but like I said the light won't come on (after the codes are cleared) until the truck has cooled off....

I have had people suggest to just replace all the O2 sensors.... Other people have said they all 4 would not go bad at once...
I have had people suggest the PCM is bad....(where is the PCM and what does it cost ??

I have had people suggest I have an intake manifold leak and it is burning antifreeze(intake manifold Is supposed to be a problem on older 4.2 v-6's).... but I have not noticed any antifreeze consumptoin....
I have had people suggest the cat converter is plugged....

No to deep puddles lately,
no to washed the engine, at least not for 6 months or so.
No to run engine with air intake tube disconnected,

exhaust leaks no. I had some trouble with threads on o2 sensor I replaced. But I thought it went back in solidly.
The exhaust manifold is the original but is sound that I know of. May check it more tomorrow if that is a possiblilty.

Battery was replaced in May or June and is a good one.
Charging system no problems I am aware of.

Thanks again.

Can you help me determine the problem... how to diagnose it and how to fix it????


Thanks

The codes you are getting is becasue the sensor is detecting a lean engine or cylinder. This can be caused by an engine misfire or a MAF sensor that is starting to go bad. Here are three guides that will help you see what's going on.

Is the heater built into the sensor, and which side is the circuit bank 2 sensor on?

A heated sensor needs nothing additional. I believe bank 2 is the driver's side. Check the injectors. The even numbers (2,4,6,8) are bank 2. (1,3,5,7) are bank 1.

I recently scanned my truck with an actron pocket scanner and got code P0133. It said the malfunction is occurring in bank 1 sensor 1. Where would that be on my truck? and what model sensor do I use?

P0133 - Oxygen Sensor Circuit Slow Response (Bank 1 Sensor 1)

Bank 1 is the driver's side, but no fault code ever says to replace a part or that one is bad. They only indicate the circuit that needs further diagnosis, or, as the case here, the unacceptable operating condition. While the sensor could be contaminated, it's more likely there's a problem on that side of the engine and the sensor is just reporting the condition. Changing the messenger won't change the message.

code Po153 02 sensor circuit slow response (bank 2 sensor 1) is this a bad sensor or something else. if it is a bad senor which one is it

Possible causes are as follows: Open or shorted circuit. Exhaust leak. Excessive fueling. HO2S coated with contaminants. Faulty MAF sensor. Leak in air induction system. Bad HO2S

I hope you guys can help, I have a check engine light that comes on. I purchased a code reader/clearer and it tellls me it is a o2 sensor . The problem is it has 4 sensors , 2 before the cats and 2 after and I am not sure which one of the 4 to change , any advice would be bennificial.

Thanks lyle

Can you post the exact code P017*

I will check this weekend and get back to you .
Also would you know how to check a o2 sensor manually ?

Thanks for the reply
Lyle

O2 sensor tests are hard to do and you ususally need special equipement, and the tests results are often inconclusive.

Hi blacktop , the code came in as p0175.
I understand this means a rich condition and it refers to bank 2. Can you tell me what side bank 2 is and if the sensor is before or after the cat .

Thanks for the help.
Lyle

p0175 came up
I understand it means to rich bank #2
What side is bank#2 and is it before or after the cat.

Thanks for any help
Lyle

If its rich on bank 2 then it has to be sensor one which is before the catalytic convertor on the exhaust manifold, as the one after the convertor, sensor 2, is used for catalyst efficency.

Bank 2 is the side of the engine that doesnt include the #1 cylinder which on fords is the passanger side.

so your looking at the sensor on the DRIVERS side BEFORE the convertor.

My car failed inspection due to an oxygen sensor being out. Where is bank one sensor one oxygens sensor on a 1997 F150 5.4L V8?
