2002 Chrysler Concorde 6 cyl Front Wheel Drive Automatic 134K miles

Hi All,

I've been gathering information about the situation with my Concorde Limited 2002, the internet is a great place. I have little experience with auto mechanical issues but I believe I can replace the O2 sensor myself, there are some online tutorials on utube showing the basic way to do this. My question is, my code displays a "P0153 – 2/1 O2 Sensor Slow Response", this sensor is upstream from the catalytic converter right? I believe there are two O2 sensors upstream and 2 O2 senors downstream, should I replace both that are upstream or just the one on the drivers side?

Any help would be greatly appreciated:)

To the best of my knowledge, that means bank 2 sensor 1. If you are on the passanger side of the vehicle looking at the engine, bank 2 should be the one on the left.

Thanks for your response:)

Just another quick question. If my mileage is not being effected (getting roughly 21 mpg in the city), should I be concerned about the O2 sensor issue. Just wanting to learn more about it, and pick up a hanes manual, so that when I try to change it myself I'm more prepared. I've read in other places if the mileage is not being effected then it is not much of a problem.

Thanks again.

I agree. If the sensor is bad, it will have an adverse affect on the mileage. If it is still running well, chances are it is just starting to go bad. But, it could cause other items to go bad if not replaced. Therefore, I recommend doing it.

As far as a manual, the sensor just unbolts from the exhaust, unplug the wiring harness, and replace the new one. I recommend using anti seize on the threads so you will be able to remove it in the future if it goes bad again. If you don't, it will rust / corrode and will be nearly impossible to remove.

Just a follow up and a question. I'm starting to notice a MPG deficiency. My car has a trip computer, and I usually keep it on instant MPG setting. When I accerlate it goes down to 5 or 6 instant MPG useage, but I am not pushing it when I accerlate, never going above 2000 rpm, once I get to cruising speed and it kicks into overdrive it lists a instant MPG of 27 to 33 which seems normal to me. Most of my driving time is at the cruising stage, unless I go thru a route with allot of stop light or heavy traffic (these routes I try to avoid). The thing is it is still listing my avergae MPG as 18.5, just below the stated MPG for the 2002 Concorde Limited. I've inflated my tire pressure to 50 psi, I roll to stop lights or down hills by putting car into neutral, trying everything to conserve fuel, still getting below average MPG than what I should be. Must be the O2 sensor right?

I priced it at a shop here for only $155 Canadian to get it fixed, just concerned that they won't fix it right the first time. Interesting thing, before I bought this car, I did a car fax and it listed a O2 sensor replacement back in 04', just doesn't list which one/s.

Thanks:)

James

P.S. How accurate is the trip computer regarding MPG readings and miles till empty readings.

The O2 sensor can cause the drop in mileage. As far as the cost of replacement, you could replace it yourself. It's just a matter of unpluging a connector, unscrewing the sensor and replacing it with the new one and plugging it back in.

As far as the tire pressure you are using. Check the sidewall of the tire. Max pressure for passanger tires usually doesn't exceed 44PSI. You could have a blow out and the center of the tires will wear out faster than the outside. Check that to make sure you haven't exceeded the recommended max pressure.

As far as the computer and MPG, they are accurate. However, if the float gauge in the fuel tank goes bad, the miles till empty could be wrong.

Overall, it is very common for O2 sensors to go bad, and yes they will cause poor fuel economy. If you know which one is bad, you could most likely save yourself about 60 or 70 dollars doing it yourself, but that is up to you.

Let me know if you have other qusetions.

Thanks Joe:)

Well I gave in and brought the car in today to get the O2 sensor replaced. They did a scan as well, and the only one that came up was p 0153, the same that came up when I checked it myself, they did this to confirm that the O2 sensor was the problem, I don't mind paying for it as they reset the computer so the engine light would be off. I got the car on the road, then a few hours later, the engine light went on again, flashing this time and at this exact time when I wanted to accelerate the car wouldn't. I pulled over, turned the car off on off on off on to get the code and now it comes up as p 0300, cyclinder misfire. After this when I went to drive the engine light stayed on consistently and at times I did feel a slight slight jerking, only when I was travelling really slow, like in a parking lot.

Obviously I plan to bring it back to the shop that replaced the O2 sensor, but could replacing the sensor cause this problem?

Thanks.

I doubt the O2 sensor has anything to do with the new misfire; however, I would return to the place that did the work. They may have moved things around causing a plug wire to short or something to come disconnected. As far as the new code, PO300, I believe that is a random misfire not specific to any particular cylender. WHen was the last tune up?

Joe
PS: It sounds like you have the same luck as I do.

Hi Joe,

Oh No, lol.

Well what I find interesting is that this misfire problem happens right after the O2 sensor replacement, so in my mind whatever they did must have done something to bring about this situation. I will test drive it tomorrow to see how the acceleration is while on the way to the shop. Question, if it is just a random misfire, rather than a specific cylinder misfire, is that good or bad?

I just bought this car in August, so I am not sure when the last tune up was, was thinking of getting one done soon anyways.

Thx again.

Actually, it makes it harder to locate. When there is a specific cylender misfiring, a mechanic can go to that cylender and check it. If it is random, it could be any.

Okay, I brought it back to the shop, they put the scanner on it and found multiple cyclinders were misfiring, I believe it was banks 1, 2, 4, 6. They investigated further, and thought it was weird as well that this happened right after the O2 sensor was replaced, so they got a new sensor and installed it. The tech took it for a drive and said it runs good now. After an hour or so, I got another Engine lignt appearing, this time the code is p 0152 - O2 Sensor Circuit High Voltage Bank 2 Sensor 1, before it was p0153. So what do you guys think this is all about?
Why some many code changes and such.

Thx.

Yes that is a possible problem. I too have seen it happen. Bosh usually makes good parts, but they can cause a higher voltage when the vehicle is cold.

So then is this a non issue, something I can live with or will it cause more problems as time goes on, if I just leave it?

I will call the shop tomorrow and tell them what's up, hopefully they don't charge me more for a OEM sensor, I've heard that they are cheaper overall then the bosch or other sensors.

It should be fine if that is the correct diagnosis. You may want to try it for a while to see if it changes.

Actually, the retail price of an OEM sensor is almost 3X the price of an aftermarket. If you can get one cheaper, get it.

Interesting, I thought I read somewhere where someone with the same problem went to the chrysler dealership and bought a sensor cheaper than the bosch.

Do you know the manufacturerer and part# of the OEM O2 sensor for my model car?

Thanks again for you help, it's much appreciated:)

Hi Joe,

I can't find the part online, so I contacted the local Chrysler dealership, I got them looking for it. The engine light went off yesterday, it was a bit warmer outside, but then on again later on at night. Mileage seems to be a bit better though.

Just today, stopped at the video store, got a movie, started the car up, the engine light didn't come on, then drove away, the accerlation wasn't there, then it kicked in, then the engine light flashed a few times then went off. When I got home I checked for a code but only p0152 came up like before. Weird behaviour, is the computer screwed on this thing?

Maybe when the OEM O2 sensor comes in and I get it installed these problems will go away, never had this misfire problem before the new O2 sensors where put in. You would think with all this technology in place it would be easier to fix? The mechanics on Tuesday thought he had it.
