Nissan - Maxima :: PO430 Catalytic Converter Code
My 2000 Nissan Maxima has a PO430 code for the catalytic converter that has been going on and off for over 1 year now. My ? is, how would I know that the converter needs replacing? Someone said there wouldn't be any smell necessarily, someone else said I would be leaking qts. of oil in between changes and someone else said it would get bad mileage. Each one debunks the others comments etc. Also just for info., this car had the ses light come on at 57K miles, my brother replaced 2 of the O2 sensors and I replaced 2 also, one duplicate one and a mass air flow as well.

Nissan - Maxima :: 2000 - Making Strange Noise - Getting Code P1320
I recently had issues with P1320 code, and after replacing a bad ignition coil by a local auto mechanic, the CEL went away. While changing the one bad ignition coil, he also changed all the spark plugs.
However, after driving for about 1000 miles, I started hearing this noise which is persistent, and I'm hesitant to drive it further without knowing if driving in this condition would cause any further damage.
What could be going wrong here for this noise. I tried to attach the video I captured, but couldn't.
Nissan - Maxima :: 2000 - CEL Code P1320 / Running Rough And Loss Of Power
My Nissan Maxima GLE 2000 is showing CEL with code of P1320 ONLY, and the car is running rough/or loss of power. The shop that checked for the code advised that it could be something related to Ignition, and also provided me with the system generated list of reasons for the code. Before I decide to do anything, I wanted to check what option I have to address this in a most cost effective manner:
1) Is there a quick way to check which coil would have gone bad ?
2) Is it advisable to change 1 LH and 1RH at a time, and see if it fixes the problem ?
3) Could it be cam shaft sensor that could have gone bad ? Are there any symptoms of cam shaft sensor failure to isolate it to one way or the other ?
Prius (2004-09) :: 2005 - Error Code P0420 / CEL Came On Again?
Just picked up a 2005 with 146k and full Toyota service history, although seems a steering recall was not done. Will run it to the dealer today to check. I need to decide a.s.a.p. if I am keeping the car or not (I know the seller, he will take it back)
Anyway to cut a long story short, two questions.
1) Car had P3190 and P0420 when I got it. Seller reset, drove home and within 5 minutes on the road the CEL was back on. Checked the codes at home and see only a P0420. Much to worry about? Seems this might be big (Cat) or small (O2). Car getting great mileage - 60mpg at 60mph and it seems to be running great. Should I worry or forget about it? Note I am in Florida with no inspections.
Prius (2004-09) :: 2005 - Pulled Over Error Code P0420
So I bought a used 2005 Prius back in August it had 88,000 miles on it and was out of warranty. But I had a full inspection on it and the car was in great shape. Well, after a few months of driving, I got the P0420 error. I took it into my mechanic who cleared the code and told me to call him if it came back on. It came back on, then I cleared it myself, and it came back on again. So it was confirmed that I had a bad catalytic converter.

Ford Exhaust System :: 2005 F150 - CEL Came On For Code P0420
Had the check engine light in the 2005 F150 (90,000 miles) come on. Got the code checked and its P0420. I know that has to do with the cat threshold levels etc. So I believe I am looking to replace the o2 sensor, if I am not mistaken.
How hard of a job is this? Ive done a decent amount of engine work. Just looking to see if that is the right thing to try first, replacing the sensor, before replacing the cat.
Also I know its the right bank, but if I am not mistaken there is a before and after the cat o2 sensor, which do i replace? Both?
Dodge - Dakota :: 2005 V8 - Intermittent Check Engine Light Code P0420
My 2005 Dodge Dokota 4.7L V8 152,000 miles has an intermittent check engine light (CEL) code P0420 ('catalylst efficiency') that turns itself off.
1) 151,000 CEL on, code P0420, checked, cleared at dealer.
2) 151,948 CEL on, code P0420, checked, cleared at dealer (Cat Conv).
3) 152,200 CEL on, code P0420, checked, cleared at local auto parts store.
4) 152,597 CEL on. No checks.
5) 152,815 CEL turned off on its own
6) 152,849 CEL on. No checks.
7) 153,137 CEL turned off on its own.
Twice in this time CEL has came on soon after a fill up from near empty.
Engine runs fine, 18-19 mpg highway.
Have seen numerous on-line reports of other possible causes:
a) base engine problems (coolant or oil) -- coolant temp sensor
b) Air inleakage -- air systems or manifold
c) Lazy front O2 sensor
d) fuel pumps
e) timing or misfire
f) what else? - (gas cap, other...)
What to check first or categories to eliminate?

How hard of a job is this? Ive done a decent amount of engine work and worked in a shop in high school. Just looking to see if that is the right thing to try first, replacing the sensor, before replacing the cat.

Nissan - Maxima :: 2011 - Bad Gas Mileage
I have a 2011 Nissan Maxima SV that has poor gas mileage. I took it to Nissan to get checked out but they said there's nothing they could do because the car is showing no codes or no check engine light. I got my spark plugs changed, it seemed like it worked but a week or so later, it went back to how it was (the gas mileage). 2 weeks later, my mechanic checked the spark plugs in front of me, no rust or leaks on them. I burn a half tank of gas every 2 days and that's just driving local to work and back.

I have a misfire on the number 2 cylinder on my 97 Nissan Maxima 5spd. The computer has been changed 3 times, and it'll work for a short time after the new computer is installed, but then the problem resumes. What would cause this to happen? The coil has also been changed.

I have a 1998 Nissan Maxima, and when I brake or am moving very slowly in stop and go traffic, my car sounds like a foghorn. I am thinking maybe I need new brake pads, but I thought brakes were supposed to squeal when they are bad. I remember them squeaking a little bit, but nothing major. Then all of a sudden I'm starting to get this foghorn sound.

2002 Nissan Maxima with 118K miles. Heating and A/C buttons that turn the fan on different levels doesn't work. It will cut on/off but the setting can be on low and it always blows on high. The temp. is correct(heat or cold) on what we set...it just always blows on high no matter what we set. It is a bush button kind of setting not a dial that you turn.
View 1 RepliesNissan - Maxima :: 2007 - Won't Start After Changing The Oil?
I have a 2007 Nissan Maxima and after changing the oil added Lucas Oil Stabilizer and when I went to start the car the engine shook for about 3 seconds and I was unable to start it again. Towed it to Nissan service and they said codes came up as the camshaft sensors were bad and engine was flooded and need to dry them out before testing it out. So on Monday I received a call from the service manager and he told me that they tried replacing the camshaft sensors but it would not start. He then said that his technions working on the car believe the timing chain jump causing vavles to get bent. Cause the engine has 107k the will not repair my car and recommend a new engine. I informed the service manager I find it hard to believe that any vavles could have gotten bent with the engine running only 3 seconds and had my car towed back to my house. I tried replacing the crankshaft shaft sensor and it still will not start. So before I attempt to open the timing chain cover wanted to see if the timing chain could have jumped only running for 3 seconds and to see if it might be something else? Still don't understand why after adding the oil stabilizer to the oil it would had stalled out like that when it was running so good and starting up with no problems. I read on line that Nissan has had many issues with their timing chain guides wearing out but can't see how the oil stabilizer would effect the guide.

My 1993 Maxima at times will not start. There is no rhyme or reason for it not starting. Either that or I have not found a particular reason or reasons for why it will not start. Sometime it is over night and at times it may happen when it sat for a couple of hours. Took it to a garage which they check the battery, starter, ignition switch, starter relay and all was okay.

I have a 2000 Nissan Maxima GXE four-door sedan, which I purchased new. In May 2008, at 39,556 miles I had to replace the alternator. In January 2011, at 45,201 miles (+5,645 miles) I had to replace the alternator again. Now, in December 2013 at 49,630 miles (+4,429 miles) I have to replace the alternator for the third time. It just doesn’t make since that the less I drive, the more often I have to replace the alternator. The replacement alternators were remanufactured and not purchased from a Nissan dealer. Do you know what would be causing the alternators to fail? Do you think purchasing a new alternator from Nissan dealer would solve the problem?

I have checked all fuses, relays, etc that I know about. In fact, I pulled all of the fuses out and checked. The switches test good for connectivity.
The sunroof is closed, but needs to tilt up (if that makes sense) to fully close it and seat the weather strip. I have tried everything and it was working fine last week with no issue. There is no sound from the motor when the switches are pressed.
