Ford F-150 - 1997-2003 :: Check Engine Light Has Been On - Codes PO401 And PO446 Came Up
Ive got a question for all you code readers out there. My dreaded check engine light has been on for about a month. I bought a code reader recently and checked it out. Two codes come up; PO401 and PO446. What these mean. My book says "Exhaust Gas Recirc. Flow Insufficient Detected" and " Evaporative Emission Control System Vent Control Circuit Malfunction". Which sensors, location on vehicle, etc..... this is a 97 5.4L Expedition.

1999 ranger 3.0. Check engine light popped up showing P1000 and P0401 codes. I think the p1000 is a system readiness test. Not sure why that came up and the 401 is exhaust gas problem. I put on a new autozone DPFE a few months ago..

View 1 RepliesToyota - Corolla :: 2000 - Check Engine Light Reading PO171 / PO172 And PO420
My Toyota Corolla 2000, 123,000 miles, Mass license plate, still getting 34 miles per gallon, has had check engine light on and off for a year.Failed inspection this June.
First garage in Somerville, without doing more than getting the three readings above, said catalytic converter was needed $350 plus labor.I was unable to do the work then and returned to NYC and job. Took to another mechanic recently to get fixed (as I wasn't returning to Mass for a while)and got only PO 171. I mentioned the other readings; they kind of scoffed it off.Trying to save me money (I guess), they cleaned the MAF filter and fuel ejectors for $200. Looked like it was fixed. A week later check engine light came on again and when I brought in found the PO 420 reading. They did not tell me if other computer read-outs were coming up as well.
Now they want to leave the oxygen sensor in front but change the one behind. Put in a newcatalytic converter $539 {they had quoted me $238 but it wasn't an OEM one I guess and they said they wouldn't warranty anything but this expensive one), charge me$137 for the oxygen sensor190 laborplus taxfor a total of a whooping $946!
I am afraid they will do this very expensive job and the check engine light will come on and htey will say o its something else.how can i be sure? also I was reading for a catalytic converter to go bad, something has caused it...what would that be? how to find out. Do they need to do the diagnosis with gas analyzer etc?
Why I spend a huge amount for an old car that is running well, not losing gas mileage, but perhaps is a bit slower on power.
Chevrolet - 3500 :: 1998 - Check Engine Light On / Codes For MAF And MAP Sensors
I have a 1998 chevy 3500 2wd pickup with a 454 engine. The check engine light is on. I have had the codes read and they were for a MAF and MAP sensors. I have replaced both. The check engine light is still on saying that I have a bad MAF sensor. I replaced it again. The check engine light still is on. What else should I look at to fix this problem??

I've got a 2001 Chevy Prizm (160,000 miles) Starts right up-after I drive for awhile and turn the engine off. It won't restart at times - I have to wait anywhere between 5 and 20 minutes till the engine will start again. The engine cranks - so it's not the starter or the battery.

My '04 santa fe 3.5 v6 gls/lx, 79k miles, gas, auto, check light has just come on while I was driving a less than 10 mile journey. How can I check what is wrong. Do I need some sort of diagnostic code checker. Do any national outlets check it for free (Pep Boys or Auto Zone, etc).
Just 5 days ago (about 50 miles only) I had timing belt, water pump, plugs and leads replaced, brakes checked and lubes flushed; BUT not at above dealers. I would rather know what the code is saying before I go back to the shop who carried out the work.
Chevrolet - Prizm :: Catalyst Monitor Not Ready But No Error Codes
2001 Prizm/Corolla - CEL is off, no trouble codes, all other monitors are ready, but not the catalytic convertor. No repairs since a new battery mid December. The smog guy (California) says that he can let another monitor go but not the cat; it costs him too many points.
Is this a converter in the early stages of failure (150,000 miles; some oil consumption)? Or is there another possibility?
Elantra XD (2001-06) :: Check Engine Light Is On For 2 P0501 Codes
I've replace the input and output transmission speed sensors on my 01 GLS. check engine light is on again for 2 P0501 codes. There is no abs speed sensor on the left side but there is on the right side which doesn't look like it is seated correctly. The transmission is still shifting kinda funny sometimes. Should I have abs speed sensors on both sides? And what else should I do to fix the random erratic shifting?
View 3 RepliesElantra XD (2001-06) :: Check Engine Light Brings 5 Codes Up
Have an 01 elantra as a second car and it's great. Just recently tho the check engine light came on and I've got a few codes that make sense since there has been some odd issues with it in the past month or so.
02 sensor CKT bank 1 sensor 2 (slow response)
shift solenoid D malfunction
shift solenoid C malfunction
shift solenoid B malfunction
Trans range circuit malfunction (PRNDL input)
So I know the 02 sensor needs to be replaced, that's fine. I'm more concerned about the rest of the codes because when cruising around 40mph the car tries to shift to 4th gear or something like that, it will bog down because the rpm is too low (maybe its overdrive, not sure).
That's a minor issue but has been there since we got the car over the summer, the bigger issue is the last couple of days, i've noticed that when driving the car around the city, slow down - turning - and then accelerating the engine/trans will buck harshly a few good times before it smoothens out, my guess is the gear change didn't go well.

I have a 2002 SF GLS/LX (?) with 2.7 L V6 2WD (60,000 miles) and it started to apply the ABS brakes in a random manner. Found out it was caused by a broken front wheel tone ring. So, I pulled the ABS fuse under the dash and it stopped the brake problem. Drove it today to pick up some wood and now the check engine light has come on.
My neighbor has an OBD scanner and he plugged it in and said I have a P0501 code and a P1529 code, but he didn't know what they meant. What they mean and are they related to me pulling the fuse under the dash? Did I pull the wrong fuse? Is there another fuse somewhere that I should have pulled?

Elantra XD (2001-06) :: Codes P0700 And P0885 - Check Engine Light Stuck On
I have an 05 Elantra GLS auto transmission, ~83000 miles. Last Friday, the car was driving fine. I didn't drive it on Saturday, but when I started it up Sunday night, that's where the issue began. First, when I shift into reverse, the car makes a noise like as when you go over a pot hole. Idle RPM is around 800.
When I press the gas pedal, usually the response from the car to go forward is almost instantaneous, but now it take a second or two from the time I press down the gas pedal to when the car moves forward. The process is smooth though, no hiccups as it does that. Next, when I was driving on the highway between 70 - 80 MPH, the car's RPM was 4000 - 4500. It even sounds like the engine is "working harder" than it usually does. The 'Check Engine' light is also on with these codes: P0700 and P0885.
Another thing I noticed is that the car alternates between running fine and running with the conditions described above. If the car run with the symptoms described above, I shut off the car and restart it. Then it will run fine, but the check engine light will stay on. Then if I turn off the car and restart it, it will go back to the mode where I have the issues.
From some research, the P0700 code just means that the TCM has the actual code which is P0885. According to the tech manuals at [URL] ...., the P0885 has the following probable causes.
- Malfunction of the A/T control relay
- Malfunction of connector
- Malfunction of the PCM
The car actually ran fine today, with out any issues but the Check Engine light is stuck on. How to replace/service this PCM item? Or maybe this issue is covered under 100,000mile warranty?
Elantra XD (2001-06) :: Check Engine Light Turned On - Codes P0422 And U0D00
While on my 20 mile commute my check engine light turned on, attached the code reader to the car and got codes P0422 and U0D00. Looked up the P0422 code to find "Caralyst efficiency below normal (bank 1)" I have a list of possible fixes but have no luck finding out about the U0D00 code. I notice I lose and a quart of oil every month and when I start the car, the first 5 seconds or so the engine revs to 4000 rpm.

I just purchased a 2005 elantra with 133k on it and she runs fine other than a slight erratic idle. And by slight I mean it will jump about 50-100 rpm idling and every blue moon it will jump up to 250 rpm sitting there. After idling for a while my CEL came on with the following codes.
P0507 idle air control rpm high
P0506 idle air control rpm low
P0170 fuel trim malfunction bank 1
P0121 throttle position sensor
What could be causing this? I took the iac off and cleaned it with maf cleaner but it didn't work.
Prius (2001-03) :: 2002 Check Engine Light Codes For EVAP System And Misfire
My check engine light came on the other day, with no symptoms or problems. Today I stopped at the Auto Parts store and had the codes read. They were P0440, P0441, P0446, and P0301. They are for the EVAP system and misfire.
I had read here that one of the codes could be for the gas cap so I tightened it and then, also as read on here, disconnected the negative 12 V battery cable to perhaps clear the check engine light. I was curious.
When I started the car again, I now have not only the check engine light, but the red triangle exclamation point. How would you proceed? The 12 volt battery is around 5 years old. The entire exhaust system was replaced last year.(not O2 sensors though)
The hybrid battery was replaced at 70,000 miles and I now have 110,000 miles on it. I really wonder why disconnecting the battery and reconnecting it caused more error lights to appear? Also, the Auto parts guy said his code reader was fine for my car but I seem to remember here that there may be a special Prius one.
Chevrolet - Blazer :: 2001 - Check Engine Light Comes On With A P0410 Code

View 4 RepliesImpala - Chevrolet :: 2001 - Check Engine Light On / Coolant Level Low
So I recently bought a Chevy Impala with about 150,000 miles on it. The check engine light is on and sometimes it will tell me my coolant levels are low. I filled it up with coolant and the message still comes on sometimes. Also, when I'm driving, I can feel my rpms go way up when I press the gas, but they car won't accelerate for shit. Sometimes the check engine light will blink, which I've heard is for safety, and my car will barely accelerate at all. I can drive it around town easily the way it is now, but I don't want to risk ruining it. On top of that, my radio and lights will cut in and out sometimes and get better the more gas I give it.
View 3 RepliesChevrolet - S-10 :: 1993 - Showing Service Engine Light Sporadically
A few weeks ago, my 1993 S-10 began showing the service engine light sporadically over a couple of weeks. Then, while I was stopped and idling at a red light, the engine revved up really high suddenly for no reason. A few days later, as the automatic shifted from 2nd to 3rd it jerked a little, as if I'd tapped the brakes or something.Around the time all this was going on, I heard something on Car Talk about the radiator and transmission being linked somehow. I checked my radiator, and sure enough the coolant was very cloudy and kinda sandy. I flushed the coolant and refilled and all the weird little transmission quirks seemed to vanish after that. Until yesterday, when the symptoms started appearing again.
