Prius Plug-in 2012-15 :: Touch Sensor Lock On Door Handle Not Always Working
I've noticed that my new Prius Plug In won't always lock and unlock using the touch sensor on the door handle. The manual states that when this occurs to use two fingers and touch both the top and bottom of the handle at the same time. This does not work either.
Problem seems to occur when in busy shopping center parking lots where other vehicles have similar systems? Once the car is back in my driveway or in the parking lot at work, the sensor works fine.
Could it have something to do with RF interference in the immediate area of my car? Is this a latent 'security feature' not really addressed in the manual?
Prius (2004-09) :: CEL On - Idle Air Control Sensor
I have a 2006 Prius with about 152000 miles. About 2 weeks ago we got new tires and an oil change before a long road trip. the next day the Check Engine light came on. I took the car back to Firestone the next day and they were complete jerks about even checking the light for me, but eventually read the code for me P505 Idle Air control sensor. They swore it was a minor error and after some online investigating, I decided that at least we could drive the trip and then get it fixed when we got back.
On the way back home, the light went out. The next few days it was fine, then CEL comes back on, p505 and also 1220 I believe. That same night - the light went back off.
A few more days of no light then BAM saturday midnight Red Triangle of doom (!) and the car stalls.
After a couple of resets, I was able to start the car again and decided to drive home instead of the dealer. On Monday on the way to the dealer, the car stalled and would not come back to life.
Prius (2004-09) :: Springs On Load Leveling Sensor Keeps Going Bad
The springs on my load leveling sensor keep getting corroded. This time I sprayed them with contact cleaner and then dipped them in dielectric grease so hopefully they won't go bad again, but I fear they might. It looks like there was some kind of anti corrosive treatment on them which was removed when I cleaned them off.

We took our 2008 Prius in for a check engine light. The dealership said oxygen sensor was faulty. Changed that and had them change the serpentine belt while there due to cracks in the belt. My wife filled up the car the next day ( it took 13 gallons) but gas gauge was not registering a full tank. We drove 67 miles and I decided to pull into a gas station and see how much it would take since the gas gauge was not working properly. It took over 7 gallons.

I have DTC code P0100 so I got to the camshaft position sensor and noticed oil in the sensor. I can't imagine an electrical sensor is a good place for oil.

I just got the warning symbol that mine has failed, so I'm thinking of trying the repair myself, too. But I thought I'd ask here: how have people's repairs held up? Have you had to go back and eventually replace it? Is there anything you wish you had done differently when you repaired it?
On a related note, I see that the Toyota Service Bulletin for this problem instructs the mechanic to "Perform the Headlight Leveling ECU Initialization procedure using the SST" and then to "Perform the Headlight Aim Only procedure." This doesn't seem like something an individual can do without specialized equipment / knowledge. Is there a way to do it? Is it unnecessary?
Prius (2004-09) :: CEL Comes On - Accelerator Pedal Position Sensor
Yesterday the Check Engine light came on, the code was P1121 Accelerator Pedal Position Sensor Error, Performance/Range. I have not yet had the pedal replaced related to the recall (bad me), is the sensor incorporated in the new assembly or is this separate and I'll need to replace it?

I have a 2006 Prius with a Back Up camera, but I am not sure if it is just a back up camera or if sensors are suppose to make noise if i get close to another car. Is there suppose to be a sensor in the bumper or was it not included?

My 2007 airbag sensor does not respond to a weight of 20 pounds or more, it continues to read "off". The dealer said the problem is in the female end of the seat belt; however, the seat belt sensor works perfectly. It sounds like the wrong diagnosis to me.

My 2007 Prius has a stubborn TPMS light. This started about a week and a half ago after I made a few trips from my house which sold to my new apartment. I had the car loaded up with stuff in each of the four trips and maybe had a lot of weight.
I checked the tire pressure after the 3rd trip and it looked fine on all of them. I set them to 35 psi and made one more trip with heavy-ish stuff. I did not check the tire pressure after that last trip but I tried resetting the TPMS light.
I press my foot on the brake pedal and hit the power button twice and then I held the Set button until I saw the TPMS pattern change to three blinks and then it stops. It then continues blinking for the 1 minute duration and stays solid. I tried this a couple of times and waited 3 minutes or so after doing it to see if it made any difference.
Am I likely not trying to reset correctly? I also have techstream on a cd and the tool and a laptop but am not sure if I should set that up and then try to debug using that tool?
Prius (2004-09) :: Symptoms Of Failed Mass Air Flow Sensor?
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.
Prius (2004-09) :: Tire Sensor Light On With Stable Air Read?
My tire sensor "!" lights been on for a while now.. it usually disappeared when i aired up the tires but with a stable air read it is still on. Tried doing a reset but it still stays on.
Do one of my sensors are faulty or do I just need a program reset? Or I can just go to a big tire shop to get it fixed or should i go to the stealership?
Prius (2004-09) :: Air / Fuel Ratio Sensor Connector Location?
I am getting code p0420 and want to replace the air/fuel ratio sensor and cannot figure out who to reach and remove the connector to the sensor. How to do it? I read several threads about it and saw instructions for the rear O2 sensor but not the fwd air/fuel ratio sensor.
I hope to remove it from below and avoid removing the inverter. From under the car I can see the cable leaving the sensor and I think I see it terminating in a connector on the left side of the engine. I can barely snake my arm up there and touch it, but I cannot get a good enough grip to press a release button and pull it free.
I got the rear O2 sensor changed in about 45 minutes.
Prius (2004-09) :: DTC P0A9B Hybrid Battery Temperature Sensor Circuit
Had a customer car with DTC P0A9B in 2005 Prius with 170k miles so out of warranty. Car would code immediately when turned on but would drive fine, 45MPG average etc.
Dealer had told customer solution is to "replace entire HV battery assembly". .
Customer battery ECU was 89890-47070.
Got a slightly newer battery ECU 89890-47071 from a hybrid recycler in Denver. Replaced only the battery ECU, cleared codes, no more problems. Car now running great.

Looking for info about the tire pressure sensors.
My 2nd gen prius was recently in an accident; I got hit directly on the passenger side rear right tire. Car has been in the shop for over a month, they replaced the rim (moved the old pressure sensor over with the tire), doorshell, bumper, and rear axle beam.
I picked up my car yesterday, and on my way home the TPS warning light comes on. I go back to the repair shop, and they said one of the sensors were asleep and they just had to re-activate it and clear the error code.
Prius (2004-09) :: 2004 - Driver Side Brake Led Stopped Working
Prius 2004 with 86K miles. My brake led light on the driver side stopped working completely the other day. For some time now (6 months) i knew the top led of the brake light was not working, but yesterday I discovered that the whole led is failing. tail and parking light on the same assembly are working fine. I pulled off the plastic door inside the trunk and I checked connections for faulty ones but everything was tight in its place. Is there anything else I can do before preparing to go to the "butcher" dealer?

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?
