Chevrolet - Malibu :: 2003 - OBD Codes P0131 (o2 Sensor) And P0405 (EGR)
Jan 13, 2015
I have a 2003 malibu with 170000 miles on it. My husband uses this car to commute to work (10 miles one way). We will be buying a newer car in a month or so but my husband really wants to keep this car as a third/back up car. I purchased an OBD 2 scanner and downloaded the torque app (I really enjoy working on cars and I wanted to have more info easily available to me). The codes that it is showing me are P0131 (o2 sensor) and P0405 (EGR?). How should I proceed? I know I need to replace the O2 (easy) but im not sure about the other code.The car has a rough idle, terrible gas mileage and seems to drive as though I have shifted it past Drive and into 1st (its an automatic).

I have a 2003 Explorer 4.6, about 2 weeks ago the CEL kicked on but I didn't notice any problem. Last week I stopped at a red light and felt it shacking a little, I took off everything seem ok. At the next light I felt it again and that time it started sputtering, I drove it for a few more days and it would sputter now and then as I was driving and every time when I would stop when it was in drive. I had the codes pulled and it came back with P2196 & P0405 (o2 & EGR).
I was going to buy a new 02 sensor & EGR but I was told that a bad EGR could be causing the o2 code also. I put the new EGR on yesterday and had the codes cleared. I test drove it for about 10 miles with no problems. Today while driving I felt it start doing it again and about 5 mins. later the CEL was back on. I got the codes and again its P2196 & P0405, Should I have changed the 02 sensor instead or what I should do next?

1998 Chevy C1500 4.3L V6 170,000 miles
My truck is stumbling and losing engine power sporadically. When this is happening I can usually drive it if I am real easy on the gas and slowly build up speed but if I mash it the engine will eventually just die completely. It has had this problem off and on for several years and now it's back with a vengeance. It always seemed to happen after a heavy rain but now I'm not sure.
Last week I had a mechanic look at the codes and he cleared them saying that once it happened again the code(s) that showed up would be a good indicator of the actual problem. The codes that were there were for a couple O2 sensors, catalytic converter and loss of vacuum I think. It happened again and his shop was closed so I got it read and cleared somewhere else and it was P0131 bank 1 sensor 1 and since I knew that one had come up before I went ahead and replaced it myself.
The next day the CEL came back on without any noticeable engine trouble. That was yesterday, this morning it rained and the problem is back and I went to get the code read and it was the P0420. There was also C0281 stop lamp circuit something or other that was new.
My gas mileage has stayed pretty good this whole time, always 15+mpg. Just wondering if my catalytic converter probably needs replaced, if I should replace other O2 sensors, or if this all might indicate something else in the engine.

My 1998 malibu starts most of the time, there is a continual light on the dash and according to the maintenance book from chevy, they are saying check your emissions system. Also on the times when the car does not start right away, the oil, battery light also goes on; the sound is rrrrr, weaker and weaker, wait 5 minutes and can start the car. This has been the pattern. Diagnostics say it is the crank shaft sensor..... I have already read your stream about crank shafts sensors.

I have an 03 Explorer 4.6L that is running bad. The code was P2196, I changed B1S1 O2 sensor and cleared code. A few minutes later the SES light was on, I checked codes and now I have P2196 (again) and P0405. Why I was only getting the O2 code and now I have it again after replacing it and a new code (0405 EGR)..

I have a 2003 Chevrolet Malibu LS.
The bulb for the parking light on the right headlight doesn't come on, it only comes on when the turning signal is activated. I'm not sure if it's the bulb or the fuse? If it's the fuse, do I need to buy electrical gloves and disconnect the battery before I "operate".

My car will start but die. it either wont turn over or if it does, the engine goes right off. The radio and lights work though. the throttle & iacv were all good. i got it towed and the mechanic brought it in his garage at end of the day. He said it wouldn't start so they left it for monday. The thing is that my ignition sometimes gets stuck and leaves radio & interior lights on. So when they tried starting car on monday, it was dead. They put different battery on & it started right up. they said everything else was ok. they charged my battery & I had no problems. until today, 3 months later, same problem. both times it happen when I am leaving work & both times it was raining & cold. Could my battery be bad? also wonder if place really checked everything out likethey said.

My 2003 Chevy Malibu recently, out of nowhere, starting idling really hard. It shakes and jumps quite a bit when it idles, much like a car creeps when it's about to run out of gas. It drives fine at speeds over about 10-15 mph, but then when it slows down it gets shaky and bumpy.

My 2003 Malibu engine will stop running all of a sudden while I'm driving. It has happened four times and I need to know why before the car kills me. The accelerator pedal goes limp and within ten seconds the check oil light comes on, the check engine light comes on, the power steering quits and then the engine dies. AAA mechanics had this car for four days and couldn't figure it out. My local mechanic has had it for five days and hasn't figured it out. I have looked on the internet and I am not alone. But there is no definitive solution to this problem. BTW, it's not the fuel pump.

First off, its a new battery and I checked my battery connections which are tight and clean. Sometimes it starts up and sometimes it gives me nothing and takes a few times before it will crank. For a few days before that started the clock was resetting sporadically... sometimes i would get in my car and start it and it would be fine - and sometimes i would start it and it would reset to 12:00. Today it started to die, twice when i was stopped at red lights it would completely just lost all power - but I was able to crank it right back up and it started right away.
Last year I had the clock resetting thing as well, it lasted over a month - then one day after a long trip I pulled into a gas station and the car just wouldn't crank up - the battery was dead and I bought a new one. So the battery I have in there isn't even a year old yet. Funny thing is I had that battery tested and the guy said it was good - now I wonder if it was my battery last time at all. Seems like its something electrical, something somewhere. The a/c goes on and off on it all the time, but that has happened for a few years now.

When the driver side door is opened there is a clunk sound about half way through the swing. When the door is closed there is a couple clunks then a thud. The sound is coming from the front of the door.
What is causing this and does it mean big trouble soon?

Finally had a good scan done on my truck at the mechanics. The reoccurring codes were P0478 and P0470. It looks like a bad exhaust pressure control sensor. Looks like an easy fix.

When I take my car in to have an oil change/checkup the garage tells me my wheels need to be balanced. However I do not have any indication that I need wheel balancing. The tires do not show unusual wear, there is no shaking while driving in the city, nor when on an expressway driving from 40 to 70 MPH. Is it possible I really need to balance the wheels?

I have a 2000 Chevy Malibu (187K mi). Last year I was driving to work (24 mi one way) and noticed when I came to a stoplight the car seemed to be really hard to stop. When the light turned green and I let off the brake, it jumped forward pretty hard then continued on the way. Once I got to the parking lot and put it in to park, the RPM's went WAY up to around 3K the second I put it in park. It did this on and off for a week or so, one time getting so high in park I was scared to drive it. It was really sporadic. It quit for a day or two, then started again. I finally took it to a transmission shop...a national chain that is supposed to be good.
After 2 weeks they still didn't know what was wrong, charged me $500 for looking at it...didn't fix ANYTHING and it's been fine for almost a year. The only thing they charged me for was hooking it up to their computer and doing diagnostics. They said they were going to have someone test each wire one by one because it was showing a computer malfunction. However they did not actually do any work on the car. Just tests. I got it back and it worked fine for some reason. Now it's started to do it again. Rev'd really high, up to 2K when I put it in park last night..but today it's been fine. What could this be, and who do I trust?

2011 chevy malibu. 3 days ago on my way to work my car would hit about 2500 rpms and drop then go back 2500 and drop continously. I stopped turned it off and it ran fine. now I've noticed when taking off from a stop it's a jerking/quick (only once not multiple times) kind of go. It used to be very smooth. occasionally the rpm problem will return but less severe.

Recently my malibu would crank but not start. The consensus was fuel pump. I usually use Cole Muffler since they're close but I've had too many issues with them so I decided to take it to Sandone Tire. Upon further inspection, it turned out to be a wiring issue. I then received a call telling me that when the fuel pump was tested with their equipment, it had 0 electrical charge, and would not run the car for more than 3 seconds, essentially indicating that there was now a pump AND wiring issue, and the pump had to be replaced.
When the work was completed, about 2 days later, i hiked to Sandone to get my car, and was hit with an almost $900 bill. $300 fuel pump plus labor, $300 labor to run the testing equipment on the electrical system, gas fillup, tow, etc. I was told "Well, we fixed the problem of the car not running, as far as the other issues (small ongoing, and possibly linked electrical problems like lighter/ac, radio, locks, etc.. that may have led to the current problem) we'd have to bring it in and look at that"
I turned on the ignition to listen to the new fuel pump, and it would not stop priming. I read that that it can be 1 of 2 things, the fuel pump relay or the pcm not receiving the signal to turn it off after a few seconds. I tried to get back into the place, but he had locked up for the night. Ok, no big deal. It runs. We'll figure the rest out later.
It's now 1 day later and the vehicle is not starting again. Though this time it "tries" to start, with a little puff of combustion here and there, but will not start. I am going to ask if they put the right octane gas in, and tell them that I had a previous idle air control valve needing to be cleaned issue, but other than that I'm stuck on how to deal with this situation.
Also, if the fuel pump was running fine then "suddenly" crapped out, and the problem is electrical, how the hell does the fuel pump suddenly then need to be replaced because it won't run for more than 3 seconds?

I have a 2000 Chevy Malibu LS 3.1 V6, the car is burning oil, and I want to know your opinion.
The car had thermostat problems and was overheated, after I changed the thermostat the engine started smoking and every body told me it was the head gaskets, but the car is not burning coolant, is actually burning oil.
When I start the car, first is the steam coming up from the tail pipe, then when the car is warm, the oil smoke stars to come out from the tail pipe.
I checked the spark plugs and all six showed a lot of oil on them, so my question is, is this because the piston rings or the engine is getting oil from somwhere else beside the piston rings. There is times when is not smoke at all, and then again a lot of smoke.
In the past I saw cars burning oil from probably one or two piston chambers, but no from all of them at the same time, and on this one when I checked, all the spark plugs were wet in oil.
I was researching about this particular engine, and looks like have some issues with the head gaskets due to overheating and the fact of the heads being made from aluminum. What can I check before taking the engine apart.
