Prius (2004-09) :: 2007 - Air Flow Meter Malfunction After Service
Apr 9, 2011
I just had my 2007 Prius serviced. After the service, my car broke down within 10km of the shop. The shop determined that the air flow meter had malfunctioned and wants to charge me about $500 to replace the part. Could the air flow meter have been damaged when the vehicle was being serviced? Specifically, when the air filter was removed and inspected during the servicing. It seems plausible that shop did something to cause the problem.

We've got a 2005 with 110K miles on it and recently the Combo Meter malf'd -- in the space of a couple days, the car didn't want to shut off twice, and once at start-up the instrument panel didn't light up. Since then it has run just fine. Took it to the dealer and they want to replace the combo meter. We never got the "Warranty Enhancement" notice (which has, of course, expired).

Faulty combination meters on the Toyota Prius. Loss of braking and power steering on the vehicle? This has happened to me 4 of the 100+ times my dash lights were not working. On those 4 occasions I was driving without the dash lights and all of the warning lights came on and the car lost power steering and the ABS braking and I had to use the emergency brake to stop. Fortunately when this has happened I have not been on the highway and there was no snow or it could have been very dangerous.
This issue has only happened when there is a malfunction with the combination meter. I understand this can create many issues within the vehicle including braking difficulties. The response of the Manager at my local Toyota shop said "well, at least you have brakes, you just won't have them in an emergency stop." Wow! I've read accounts of people going 65 mph and losing brakes when this has happened which could be very deadly.
I'm surprised at Toyota's response with this possibly deadly issue. I'm also surprised that the Combination Meter Failure has not be recalled because based off what I have read about 3% of Prius owners have experienced issues with this and the braking system. At what point does a "warranty" become a "recall"? Please note that this issue is separate from the "accelerator recall".

I have recently noticed that the ODO meter of the car does not work i.e. it is stuck at the reading (57735 km) it was on when I got the car and does not record/show the increase in mileage. the trip A and B are working perfectly fine. I took the car to the local Toyota dealer but he has no clue what is wrong with it, the guy there suggested that ECU is working fine but the ODO meter is damaged and needs replacement.
I am not sure what the guy at the dealership suggested is correct because what i think is that if ODO gets damaged then the whole speedo meter should mal function.

I have a 1993 Saturn SC1 with 200K miles and two problems. I can run the AC on a hot day for nearly an hour, then the air flow fades away even though I can hear the fan still running. If I turn it off for a while, I can then turn it on again, and it runs fine for a while but then fades again. On a cold, rainy day, even though the fan blows fine out the dashboard vents toward me and my passenger, there isn't enough air blowing out of the vents below the windshield, which fogs up so I can't see.

I am preparing to combat the old P0401, Insufficient flow issue. While looking at the steps in Alldatadiy the very first decision essentially forks on "EGR System Module" or "Others".
I am just guessing that, since the choice is there, some engines will have one and some will have the other. But I thought I'd come here and see if I could learn a little more about it.
How can I tell what my truck has? I'm sure there is some difference...

I just get my water inverter pump changed yesterday and what I have noticed now every time I power off the car, I can hear water flow. I did not hear this kind of sound before. What could be the problems with my car now?

I have read all the posts pertaining to this code, replaced my coolant flow valve, bled all the air out of the coolant system and still am getting the cel with the 1121 code.
I have tried setting multiple coolant flow valve positions, checked all wiring in harness, coolant level is full in rad and reservoir, checked temp sensor at bottom of storage tank, checked pump operation at top of tank to attempt to clear this code to no avail.
Is there a default position the valve is to be in before cold start up?
Is there anything else that can trigger this code? What am I missing?

Today the flow rate of the air out of the vents on my Prius has noticeably dropped.
It makes no different which vents I select (front, feet, or windscreen).
The blower seems fine - it's still making its normal noise.
The air still blows out nice and cold, there just isn't much of it coming out, even on full blast.
I've pulled the cabin air filter and checked it's not clogged, so it seems like there must be a blockage downstream of the blower.

I had to have my 2009 Prius towed 2 days ago. It has just over 73000 miles. I was on the highway and suddenly experienced a lack of power. Eventually, the dashboard lit up: check engine light, big red exclamation point, and my favourite: it said "problem" on the center display. I pulled over and let it sit for a few minutes and tried starting it.
All the same warning lights came on. The battery level was at 1 bar. The gasoline engine would start for maybe 10 seconds and shut off. I could move the car on battery power only, but I had several miles to go before the next exit, uphill, so I figured I needed to be towed.
Long story short, my dealer said all this is due to a failed mass air flow sensor, and is going to replace it. Does that make sense? I thought a faulty sensor might make the car run roughly or whatever, but not actually prevent the engine from running.

My last ride was as 1988 Ford pick up 275,000 miles ... the poor thing finally died ... but it gave good service right to the end. I replaced the Ford with a 2009 Prius and it's a great car. So far no problems just routine stuff until a day or so ago. The little yellow "Windshield air flow indicator light" can on. I checked my Bentley book and it doesn't tell me anything. So what I should be look for to fix the problem. Other than "Take it back to the dealer"

Last week, I took my 2006 Prius with 180k miles to Meineke for oil change. They pointed out that my front brakes need work and brake fluid needs to be replaced. I've been told about brakes by another mechanic. Two days later, my check engine light is on.

I have a 2006 with 155k miles. I took it into the dealer for a mini service this week. Drove home after the service was complete, then drove to work yesterday. On the way home an alarm sounded and the red triangle light with !, the break system light (O) with !, the VSC light and the engine CHECK light came on.
A friend used his scanner to read the error code for me and it reported a "p0a80" code. What does this code mean? Replace the hybrid battery?

I have a 2005 Prius with 130k miles on it. In Oct 2012 I took it to the Toyota dealer for 120k service. They performed the following:
120k service
Replace serpentine belt
Clean and adjust drums
Replace cabin/hepa micro filter
Replace brake system fluid
Since then my car's mpg has dropped from ~45 to ~35mpg. I specifically notice that the pickup is completely gone and that it seems to "drag" pretty badly when starting from halt (stop sign, a light etc). Once it gets up to ~40mph, it appears to be doing all right in terms of mpg. What could be causing the "drag" and mpg drop?

I dropped my car off two Thursdays ago for servicing. I planned to leave the car with them overnight because I needed the 150,000 mi servicing, the steering extension shaft recall, an oil change, and a new battery. The technicians performed a safety check as per the 150,000 mi servicing and reported nothing wrong with the airbag system.
I picked my car up at the end of the following day. When I started up my car, I noticed that the read air bag light was on in the car. Since the servicing center was closing and they had reported to me that my car was safe, I did not think there was a safety issue. I left with my car and parked it in my driveway for the weekend.
On Monday, while driving, I noticed that the lights in my steering wheel were not on and none of the buttons worked (cruise control, volume, temperature, ect.). I called the Toyota dealership that afternoon and left a message. They called me back on Tuesday and scheduled me to come in on Thursday.

Had my '05 Prius in for its 100k service and TSB for water pump (the original one failed and was subsequently replaced under original warranty, so this one should be *better*, right?). All was well before the service, but now it seems to idle almost all the time, often at very high RPM, which it usually would do at full charge (which seems to be normal) but it was still a few bars from full. When starting up an hours after a long drive, the engine ran for a full five minutes in park and probably would have run the tank dry if I had enough patience. No heat or AC running, and the outdoor temp was 65. The engine will eventually shut off after a long period of driving and generally behave normally, but if I drive a stretch uphill, it will run and run (several minutes at least) even stopped in a parking lot.

For several months now, my 2007 Prius has been making an intermittent buzzing sound from the engine bay. When I first heard it, I thought I had hit the little lines they cut into the road to let you know you've drifted over the center line - the sound is like that, a low-pitched buzzing noise. Today, the check engine light came on as it was making that noise. I put a code reader on the car and got P1121, a bad coolant flow control valve. Wondering if the sound and the faulty control valve are just coincidental or if the valve might make that noise when it fails? And if not the valve, what the sound might be?

My wife and I were driving around town the other day. While merging onto the highway we hit a nail. I put the donut on and went to TiresPlus where I have gone since I started driving. I had been thinking about replacing the front tires due to wear and the nail wen in the side on the rear. Anyway I purchased 4 Firestone Affinity Touring tires and went on about my day. My wife drives 100 highway miles a day and then does some city driving. This week she has lost about 5mpg's according to the display average. Also the service light has come on. Can this all be tire related?

The check engine light on my '05 Prius has gone on and off a couple of times and is giving me a P1121 code, which I found out means "Coolant Flow Control Valve Position Sensor Stuck". Does this have anything to do with the hybrid electric coolant pump that was replaced under recall a while back?

My check engine light was throwing the code P1121 for the coolant flow valve. Toyota replaced it under a warranty enhancement (I have 134k on it), and since then my mpgs have gone from 46 to 50.
My AC is working much better now, too. My theory is that the valve can be in a semi-failure mode for a long time before throwing a code. Now that My coolant is flowing the way that it should, heat is being dissipated more efficiently.
