Rodeo :: 2000 - Check Engine Light Came On / Code P0446


Jan 8, 2007

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.

Silverado :: 2001 - Service Engine Light On For A Long Time - P0446 Code

I have a 2001 1500 with the 5.3V8 motor (ext. cab sb 4x4 LT). I was my dads and had the service engine light on for a long time for the P0446 code. I replaced the vent valve and the purge valve and light keeps coming back on. Usually can go for a day or so and then it comes back on and I get the same P0446 code.

Rodeo :: 2000 - MIL Light Keeps Illuminating With Code P0401 Low EGR Flow

The MIL light on my Rodeo keeps illuminating with code P0401 "Low EGR flow". I had the EGR valve replaced and it ran fine for a while but came back on less than a week later. It was then found to have a leaking intake manifold gasket (which was still covered by warranty) but the code still came back on less than 24 hours later. This has been going on for about 2 weeks and no one around here seems to know why. What else would cause this code to be returned?

Rodeo :: 99 Honda Passport - Check Engine Light Popped On And Off For Awhile And Now Steady

I have a 99 honda passport, runs like a dream. Let me say it also IDLES perfectly.

I usually get about 300 miles to the tank, but now my miliage has dropped significantly. The check engine popped on and off for awhile and now its on steady. The computer reads the error of "Insufficient EGR Flow". My mileage has dropped down to about 240-250.

I've already put a brand new EGR Valve in it. That's the only code the computer reads.

I know my mechanic cleaned out the valve part itself I don't' know if he did anything other then that.

When he put the new valve on the car ran without the check engine light for a day then came back, and if I am not mistaken my gas mileage was back to normal, but since the check engine light has come back on the mileage has dropped back down again.

Toyota - Solara :: 2000 - Check Engine Light Code P1410

I have a 2000 Toyota solara. Everything runs fine. No misfires or weir sounds. But the check engine light has been turning on and off. It turns off at random times and usually turns back on after I get gas. I finally got the code scanned. It is P1410. While at autozone I got a new gas cap based on prior postings and filled up the tank to see if that trick would work. To my delight, the cel turned off upon starting the engine. It remained off for thirty minutes before it came back on. So now I am stuck with the code.

I've got a 2000 ex limited with the v10.4x4. The engine light came on. So I had it scanned. Also the a.b.s light is on.and the overdrive off light was flashing but now isn't. The parts store that scanned it said code was po500. Told me it's a speed sensor but that there's 3 of them on the truck. Which sensor it is.

Ford Super Duty (1999-2016) :: Code P0446 And Check Fuel Cap Warning Came On

Got this code a while back (several hundred miles) but have had no runability problems. I know it's the evap canister but my mechanic tells me it could be a myriad of things and he might spend hours on it and still not be able to resolve it. I plan on driving this truck til it's worn out. I've put 125,000 miles on it in 10 years almost all highway. I should be putting much fewer miles on now, only using it when I NEED a truck which should be less and less, mostly for hauling toys.

I hate to drive this thing another 10+ years with the engine fault light on but my mechanic says that if something serious goes wrong it will start to flash. A couple days ago the "check fuel cap" warning came on, but goes off if I hit,the odometer button. I got a new gas cap at Reilly's but it seems like a real POS compared to OEM, very light, and the check fuel cap warning still comes on.

Accent LC (2000-05) :: Check Engine Light Came On / Code P0740 - Car Started To Choke

while scraping ice off the windshield this morning with the car warming up, it started to choke, engine light came on. Used my OBD reader and found only one code, that being p0740. Cleared the code and all was fine after that, it drives the same way it always has and nothing feels different, revs are the same shifts gears the same. I know it had something to do with the torque converter clutch.

Accent LC (2000-05) :: Check Engine Light / Code P0422 Catalyst Efficiency

Got this engine code error, how to proceed?

I have a '00 accent, just purchased a few days ago from a private party, when I bought it, I had a mechanic look it over, gave me the OK and said it passed inspection, no mechanical or obvious running problems with the car.

So I was driving around yesterday and the check engine light came on, took it to get the oil changed because I wasn't sure last time it was done, had the oil changed, light stayed on.

So I took it to auto zone to read the error code, was given this information. How to proceed?

Yaris/Scion & Vitz :: 2000 Echo Check Engine Light On / Code P0171

First owner, 192000 miles. Check engine light came on during last winter, I put fuel injector cleaner with gas and it went away for a while. It came back on, if i reset, I can drive for about 50 miles before it comes back on line. Also, may be two or three times a week, when moving after a stop, the vehicle stalls, i have to take the feet of the gas pedal and give gas again.

I called up the dealer asking for fuel filter and fuel injector parts prices. Fuel filter is in the gas tank and not meant to be replaced. The fuel injector I was told 4 x $155 each. For diagnostics they need $100

See attached, I was able to clean sensor 1. I could not unscrew sensor 2, the screw is rusted, plus there is no room to get a longer screw driver and turn.

2000 Tacoma v6 has has always ran good, but has check engine light code P300 & P306. cly 3 & cly 6 missfire, lean bank 1. Vacuum test showed no problems.

I've changed plugs & wires, switched coils around cleaned mass air flow sensor, checked timing. Ran Seafoam through intake, and gas tank. Check engine light went out for about three miles, then came back on. What else can I do to keep that blinking check engine light off?

Accent LC (2000-05) :: 2001 GSI - Check Engine Light / Mysterious P0300 Error Code

Mystery issue with my 2001 Accent GSI (5-speed manual, 1.6 L). I'm getting a P0300 error code and the Check Engine light (the light is like an old friend, I miss it when it's not on). This happened four months ago and I replaced the ignition coil - seemed to fix things - but now the light and the error is back with a vengeance. Car stumbles and runs rough. Changed the plugs and plug wires, but no difference.

BTW, there's a small pin hole in the upper part of the gas tank (just enough to give it a gassy smell when the tank is full) but I don't think the hole would be big enough at this stage to cause the check engine light to come on in the same way it does if you leave the gas cap off or loose.

Lexus - RX300 :: 2000 - Check Engine Light Code P0171 Bank 1 Too Lean

2000... I have a code P0171 bank 1 too lean. My question is does this exclude anything that will effect both banks? If it was MAF sensor or fuel filter would it set code and say banks 1 and 2 running too lean? In which MAF sensor ohms out correctly. I cannot view fuel trim files. I have looked for a vacuum leak with no luck. I got some cigars to try to smoke it to see if there is any vacuum leaks. Trying to narrowing what i need to checks.

Accent LC (2000-05) :: Check Engine Light Error Code P1128 / Too Lean Intake System

This is the infamous error code many Accent owners might have experienced it. The code refers to "Too lean intake system". People try to replace all kinds of parts like ECM, MAF, O2 Sensor, TPS, Fuel Pump, Fuel Filter, etc. according to my research. I just bought a 2001 Accent and the P2188 light came on. I wrote an email to Hyundai Corp. Asking what would be the most likely part that will cause the (P2188) check engine light to come on.

Accent LC (2000-05) :: Check Engine Light Code P0422 / Slight Valve Cover Gasket Leak

I bought the little car to get off my motorcycle and its done great. But, after a couple trips around town my check engine light came on, and I imiditely noticed a change in my idle and engine performance. Im assuming my engine changed the air/fuel ratio to account for the sensor indications. My initial code read came back with four codes which said something about spark, and O2 sensor, and emissions. I went ahead put new spark plugs, gaped them as well as replaced the first O2 sensor.

After that I reconnected my battery and sure enough no engine light and my idle felt even better than before. (by the way my old plugs looked normal) But shortly down the road the light came on again. My idle did become a little different but not like my first encounter with the engine light. My power too seems a bit degraded, as well as the engine's sound. As of right now I am only reading one code P0422, which I do not see in the manual. I read online that its probably my catalytic converter or my engine is running at an improper air/fuel ratio. I am praying that it is not my catalytic converter and just my engine computer throwing things off.

Other things which may serve as clues:

Slight valve cover gasket leak (I will change the gasket when I do my timing belt job along with other seal and probably the water pump)

When pumping gas I can get about 90 cents in at a time, now more like 40 cents since the Saudis lowered our gas prices. Assuming I've got some kind of venting problem.

Car has 107K manual shift.
