My camry 2000 recently the engine light's on and the codes are P0446 and P0401
P0401:The PCM has determined that there is insufficient flow in the exhaust gas recirculation system.
P0446: The PCM has determined that a malfunction exits in the electrical circuit fo the vent control in the evaporative emission control system.
2000 Amigo 3.2L V6.
My check engine light came on, and I went to autozone to get the code read. The code was P0446, "a malfunction in the electrical circuit for the vent control in the evap emission control system." I was wondering if this could be a simple fix...would cleaning the EGR valve do anything to get rid of this? Maybe this could work, but before the light came on, the amigo was taking awhile to start up (usually 4 cranks, with me pressing on the gas). And oh yeah, the check engine light didn't pop up until after I let the car sit for 12 days, while I was on vacation.
I also have a side problem...when I turned on my car for the first time after my vacation, besides the check engine light popping up for the first time, my ABS light also came on. I've tried the whole turning off, turning on the car and driving real slow process, but the light remains on. It just seems really interesting that both lights came on right after my car was sitting for awhile.
I'm thinking about taking the amigo to the dealership to get it checked out.
2001 Camry 4 cylinder. Check engine light came on yesterday. Advance Auto pulled out the code P0446 for the evap. emissions system vent circuit.
The car has no symptoms other than this and is current on all maintenance, but obviously it is a 10-year old car and so it goes.
A couple of weeks ago the check engine light came on and when I had the codes checked it showed a problem with the EGR valve. I replaced it and the light went off. A week later the check engine light came back on but when I had the error codes checked there weren't any. After a few days the light went off but earlier today it came back on. There are still no error codes.
I forgot to mention that it's a 2000 Camry, 6-cyl.
I had my 2000 Toyota Camry with 133,921 miles on it seen because of the check engine light.The codes obtained at the repair shop were:
P0136: Oxygen Sensor CKT Malfunction Bank 1 Sensor 2
P0446: Evap Control system Vent CKT Malfunction
They then ran a smoke test and found that the charcoal canister was leaking and needed replacement. The mechanic said that not doing the above would not affect the car's performance or its safety but it would not pass inspection with the check engine light on and with those codes.
I have a 2000 Toyota Camry with 90,300 miles. Last week check engine light came on and mechanic said it was P0440 and charcoal canister needed replacement. Did the repairs and 20 miles and two days later CEL is on again. Take it back to mechanic and codes this time are P0441 and P0446. I'm told I need a new gas cap, so it's replaced with new one from dealer. 15 miles later, CEL comes back on and I return to mechanic. This time it's reading all three codes, but they can't find anything wrong. The only parts not replaced are the vacuum seal valves, which mechanic says test as good. They reset lights and 15 miles later, the check engine light is back on. My mechanic is baffled. What the problem could be or what they should check? Car drives fine, but light coming on is annoying.
View 16 RepliesI own a 2007 hyundai accent currently around 123,000 KM's I've got my check engine light on and it has been on for a few weeks now. The Code its giving me for it is P0446, ( Evaporative Emission System Vent Control Circuit) Is what it is saying. I also notice when I put fuel in my car it does not want to start unless i turn the key over a few times or pump the gas pedal..? What to replace for this code?
View 9 RepliesI just got a Check Engine light on yesterday. I went to Autozone and got an OBD-II Trouble Code: P0401, Insufficient EGR Flow Insufficient. The Autozone guy showed me an EGR valve for $164 and said it maybe blocked or something. I also checked with a friend who says that as long as the engine is not overheating it should be okay for driving for now.
So the far the car runs just fine, I haven't experienced any issues out of normal. Does the code mean the value need to be replaced?
The Check Engine Light is on. Diagnostic Codes: P0722, P1618, and P1633. Do these mean the output speed sensor/connector wires should be replaced? Is this a DIY job?
View 1 RepliesI've read many threads in here, but I didn't find problem of my car. It's Toyota Prius-3 2010, check engine light on and code is P0401. EGR Valve works well, I cleaned pipe, gasket, cleaned throttle plate and everything but nothing works.
I have (light on) it maybe 1 year or more, the light goes away and come back,I'm in Los Angeles and all they time is sunny day and weather is nice, I've seen 3 times, when i drove in rain evening and morning I didn't see light on.. then, couple days and comes again. I think maybe EGR cooler has to be replace? or I do not know why in cold weather time light goes away..
Car: Toyota Camry 2002 .. Mileage: 150K
Symptom:Check Engine light went on a few days ago.
Checked codes and got these (3):
1) P0420
2) P1310 and
3) P0420 P ("Pending" ?)
I also checked I/M Readiness and got these suspicious-looking values:CAT: NOT RDYEVAP: NOT RDYO2S: NOT RDYH02S: NOT RDY
NOTE all the other I/M values were N/A
Researching the Codes, it sounded like Ignition, and possibly the O2 sensor on the Catalytic Convertor. I had just had some engine work done by the dealer -- actually, replaced spark plugs -- so I figured to go back and bitch him out for screwing up my car.
A few days later, before I could engage my Rage, I went back and re-scanned. First I noticed the CEL was now OFF. Scanning, I now I get "NO CODES", and all the I/M values are now N/A; No more "NOT RDY".
What do you all make of this? Should I be concerned now that the CEL is Off, and I get No Codes with a scan?Or maybe I should take it to AutoZone for their free CEL diagnosis -- would their machine be more thorough than mine (Autel MaxioScan 300)??
2003 Camry LE, 4 cyl, 165k miles – Got all of the above codes. Obviously checked gas cap and no issues there. Checked both VSV underhood and had clicking. Checked VSV at canister under vehicle and no clicking. Used a Dremel oscillating tool with flat metal blade to cut off rusted Philips head screw. Removed VSV and checked by jumpering to battery. No clicking, but did draw a tiny arc. That told me it was “trying” to actuate. Sprayed PB Blaster into hose fittings of VSV and mowed the lawn. Came back to VSV and it now actuated – but very slowly and delayed. Sprayed electrical contact cleaner in hose fittings with the VSV jumpered and open. Activated VSV several times and sprayed contact cleaner through the hose fittings several times – both directions. VSV began to active quickly. Put VSV back on vehicle. SES light went out by itself after it ran the EVAP test.
View 3 RepliesI have a 2000 Toyota Sienna that has had a check engine light for a while. The light would come at times, and go away at others, with prolonged intervals (days, weeks, months) with or without the light.
Suddenly it started losing power, especially on hills (even a small hill). The codes I read are (I include code interpretations from internet search):
P0300: Random or multiple misfire.
P0301: Cylinder 1 misfire.
P0304: Cylinder 4 misfire.
P1130: Air fuel sensor
P1150: I have not found a problem definition for this code.
Might these codes be indicative of a particular problem, or is each problem more likely a problem with its own cause?
My 2010 Prius with 72k miles on it. I bought a OBDII scanner and read P0401 Exhaust Gas Recirculation Flow Insufficient Detected. The check engine light comes on for few days, then go away for few weeks and then come back again. It's been doing the exact same thing (Come on for few days and then go away) in last few months. But I do not feel any different in terms of driving.
View 9 RepliesSo mad today. Check engine light came on, plugged in my scanner, got P0441 EVAP Emission Control system Purge Flow Fault and P0455 EVAP Emission Control System Leak (Large).
8-month old '13 TCH XLE is getting a check engine light already.
I have a new to me 07 MDX with 82k miles. Exactly at 1 mile over the 30day/1200 mile used car warranty the Check Engine Light illuminated along. The NAV screen showed an emissions code P0401. I really don't notice any symptoms in running at all. Anyway a few drives (on/off) and it turns off for four days. It happened again with same code. Again few drives it went off. It seems to happen when driving easy. It gets great MPG in mixed driving on average (20MPG) which is far better than its rating. Should I wait till it stays on steady before I address this?
View 3 RepliesI just picked up a 2011 Ford F350 about 8 months ago. I have had troubles with the check engine light coming and going. Now it's been on for good with loss of power. I have had the codes read and they came up as the p0401 and a code about the def heater. I can not remember that code off the top of my head. After some searching I have found a video about the def heater but nothing about the Egr cooler/valve. Is there anything out there about how to clean and remove the the cooler as I will be needing to do repairs myself as the truck has no warranty.
View 10 RepliesI have a 2000 Toyota Camry that has a unique problem. The Check Engine light NEVER comes on even when first starting the car. I have access to a scanner and know that the car periodically throws a catalyst code but the light never comes on. I just assumed that the bulb was burned out.
Today while solving a non-working clock issue I had to take the instrument cluster to get to the clock. While I had it out I decided to check the Check Engine Light bulb. It looked fine so I took I replaced it with a bulb that I knew worked fine. Again, nothing. The bulb doesn't light at all. About 4 weeks ago my timing belt broke while driving (non-interference motor) and it threw a code for the camshaft position sensor but again the light never came on.
Why the light never comes on?
I have a 2002 Echo with 185K miles on it and i have a 2003 Echo with 101K miles on it, Both have P0446 P0440 P0441 codes coming up on them, the 2002 I replaced the gas cap, VSV valve and the rubber hoses from the throttlebody to the hard plastic line in the engine bay, and the 2003 I only replaced the rubber lines in the engine bay.
View 14 RepliesI have a 2000 Toyota Camry with about 136,000 miles on it. Recently because it was making a loud noise and because the check engine light was on we got the exhaust system changed at Coles and this made the car silent as before.The mechanic there checked the check engine light code and reset it and he said it was an Evap code.He checked the fuel cap and found it to be OK. He said that if it comes back again I have to get it checked by some one who has a smoke machine to detect the leak and this could cost me about $100/- to set it right.The check engine light has come back again.
View 4 RepliesOn my 98' f250 4.6L 4x4 .. My check engine keeps going off and on, I finally pulled the code and its the P0401. The truck pings and knocks now and than and idles a tiny bit rough sometimes but overall runs good and gets the same mpg it always gets.....is this a bad egr valve?
