Prius (2010-12) :: Engine Light Suddenly Get On When Driving - Error Code P0401
Apr 12, 2015
I have a Toyota Prius (2010), and the car has run for about 2800000 kilometers. One day when a was driving my Prius the engine light suddenly get on. So I went to a car car mechanic, he checked the car and told me there was an error code (error code: P0401, exhaust problem (exhaust recirculation flow).
So I bought a liquid that I put in the gas tank, the liquid would clean the exhaust pipe, but the engine light was still on. The engine light is usually on at least 2 weeks, then disappear for about 2 days and come back in two weeks…The car is driving normally without any problems.

I'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..

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.

I have a 2010 with over 200k I am getting the same code.
I took out the EGR, the tube and the intake manifold cleaned them all..( was real bad) and am still getting the same code. Tech stream is saying egr flow insufficiency. Min 0.99 max 655.35 test value is 0.48.

I have a 2008 Sports Trac, with a 4.0 SOHC engine ... 165k miles. Last week my check engine (CE) light came on and the code is P0401 ... too little flow on the EGR system. I first tried cleaning the existing valve - but CE light still came on. So I replaced the old EGR valve, cleaned the SS tube from the exhaust manifold back to the EGR valve and the CE light is still on. I have not driven the truck since I replaced with the new valve ... only fired her up in the garage. Is this something that could possibly clear up given a couple of miles?

So I changed my spark plugs, due to an error code saying p0301 which means cylinder one misfiring. I reset the engine light disconnecting the negative battery terminal. Once it reset it ran rough for a few miles. I put about 50 miles on it and it seems better.

Suddenly today, I get a "Check Engine" light while driving. Scangauge II says it's a P1430 error. I found two different suggestions, but where these are located on the car.
P1430-Electric Air Pump secondary Failure
P1430 -Vacuum Sensor for Adsorber and Catalyst System Circuit Malfunction

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?

I have a 2010 Toyota RAV4. In February 2014 at 34,600 miles when the car was 46 months old I had the EVAP (charcoal) canister and filter replaced for $1,300. Error codes were P043, P0401 and P0402. Recently I had the following check engine error codes appear (P043E & F, P2401, P2402 & P2419) and was told by my mechanic that the car basically had the same problem. I am now at about 50,000 miles. I don't believe this type of problem is very common; also I think that the EVAP should continue functioning for a lot longer than ~4 years and now ~1.5 years. How likely is it that I got a "bad" original EVAP charcoal canister & filter and then the replacement was also "bad"? Might there be something else that is defective that is causing the EVAP canister to go bad? I don't generally top off the gas tank when filling up.

I 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.

I just bought a 2003 F250 from a used dealer. Unfortunately the service engine light keeps popping on and putting out the code P0401, I have replaced the EGR, cleaned the inside, and cleared the code. However it continues to keep popping up and then it will turn off after a couple of days. I mostly drive in the city and the code generally only pops on when I drive on the highway. I have also noticed a lack or delay of power, when I really hit it hard, I think its because the computer is keeping the egr valve open. What it could be?

As the title says it all I have a 2010 Malibu LS with roughly 88k on it and just noticed that the CEL light came on last weekend. On Monday the light went ahead but it came back on this morning. Took it to Autozone and the error code was P0172, Fuel System Too Rich, Bank 1. I noticed this happened last weekend after putting in some gas at QT. The Autozone guy recommended some fuel injector cleaner as a starting point and recommended using pure gasoline (premium).

Up until this morning I thought I had almost a perfect car with a potential of lasting for 10 years but this morning, while I was driving on a local road with 35-40mph, so suddenly my car stopped moving and I couldn't even pull over as it completely stopped with no error or any warning/alerts! So, I turned it off and on again, it started working but I was still nervous if it would happen to me again while driving on a freeway but it didn't and I have made to work safely.
Now a question is should I bring it to the dealer today and have them run their diagnostics on their computer to see if anything is wrong with the car engine/ battery/ or anything else or should I just reboot it like we do for computers and go on everytime it happens? It's just little scary to think of its happening during a busy highway driving! I have driven it since July and has about 14K and I have had a good MPG of anywhere between 50 to 60.

I had to change my fog light fuse tonight, no reason found for that. However, I somehow triggered an error code, P01C1. I managed to reset it, but what this code means?

I have a trouble with my 2008 prius; red triangle engine light is coming and when i try to push the gas pedal it feels like it's freeze, the car does not accelerate so I have to stop.
After i turn it off and start again it drives ok, but a triangle is still there and there is error code POA90 ( two different scanners show same code with two descriptions; the first is "MOTOR PERFORMANCE"; the second describe it as "14-volt power module system voltage high").
Specially it happens when i drive up the hill and push the gas pedal harder. What it can be? I took the car to the Toyota dealer; they looked for 8 hours and find nothing; i can't do it again as the car do not have a warranty and the dealer charge for hours.

Bought my 2010 Prius with some issues, most of which are now fixed.
The remaining issue is the mentioned A/C error code: B1498 A/C Communication malfunction (A/C inverter local)
What part this is, and the OEM part number? Where is it located in the car?
Previous owner claimed it was some error with the A/C Control unit.

Check engine light and P0010 code in my Gen III 2010 Prius...

I have a 2001 Prius with 210,000 miles. The inverter and traction battery were replaced last year. I started getting triangle and check engine lights about a month ago and the scan tool read p3191 p3006 p0300. The car would barely start in the mornings and the dash lights would be dim. I replaced the 12v aux battery today and all the symptoms went away. Driving home the triangle/check engine light popped on again and I stopped at Orielly's to use their scan tool. It now only reads P3006. I called a local mechanic who suggested to drive it a bit and clear the codes because the battery needed to equalize. Is this true?

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?
