Oxygen sensor replacement?

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?

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

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

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

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?

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

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

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

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

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?
