Prius (Gen 3) Fuel :: Adjusting Temp Up Or Down Hit Efficiency When Not Using AC
Aug 6, 2013
When NOT using A/C, does adjusting the temperature up or down effect efficiency at all? Take for example, if the outside air temp is 75 degrees, is it be optimal to set the temp setting to 75 degrees and ventilate with outside air? (in this case, I assume the system doesn't really have to do anything except run the fan) If you set the temperature to far below the outside air temp, would you see an efficiency hit?

Is it just me but why cant I adjust the cars temp without the fan running? I like to keep the air selector on fresh air from outside and since its colder now the air comes thru the vents cold. If I try to make the temp higher with the steering wheel controls it wont adjust unless the fan is running. Once I turn the fan on them make the adjustment I can then turn the system OFF and it will stay at the warmer temp. Whats up with that?

2010 Prius IV. Map display not adjusting to night mode when her headlights are on. I tried looking at my 2014 Prius Three, not III because it isn't a 2010 and only 2010 used uppercase Roman numerals for model designation, to guide her through it over the phone but her menu options seem to be very different from mine as she didn't have an options button on her map.

I've got a 2004 Prius with about 140,000 miles. Overall, the car has worked great, and I've kept up with regular service.
Several months ago, I started having bad misfiring of the engine. When I got it into the shop, it turned out to be two faulty ignition coils. The shop advised me to replace them all, which I did. Soon afterwards, however, the CEL came on, indicating a P0420 - "Catalyst System Efficiency Below Threshold Bank 1".

I checked out a 2006 Prius yesterday a guy is selling. It had the CEL on (not sure why somebody would try and sell a car with that, but anyway). He said that it's because they get gas at a station that consistently doesn't tighten the gas cap enough but by the time the tank is down to 1-2 bars the light always goes away. Although I don't doubt his story, I absolutely doubted the cause. So I took it to get the code pulled and it was P0420, which is catalytic converter threshold below efficiency.

Does the prius c heater work if we set inside temp higher than outside temp ?(Difference is 2 or 3 degrees ). Is the heater take more energy than AC ?

I replaced my battery. Once I connected my new battery, my fuel and temperature gauge started working strangely. They would either be high, then go low, then go back high. My interior lights, clock, and radio stopped working. Could it be a relay? I checked all the fuses with a test light and they all looked good.

I have a 2010 Sonata. The fuel and temp gauges stopped working. Tank is full and engine temp is good. Both dont move when you turn the key on. Tried to find a fuse that they may be on but couldn't find it.

2004, 3 door Accent, 150K miles. This has been going on for many summers now (had an idea when driving from work). Well when I got home from work, gauge still read E, turned the car off, then back to ACC, still read E.
Opened the fuel cap, didn't hear any hissing noise or any indication that there was alot of pressure build up, put cap back on, turned to ACC, and gauge read normal.
So after a long story my question is this, is there a pressure regulator that when it over pressures, lets it vent, and what is it called and where is it located? I am thinking that regulator might be stuck closed.

Well I have a 93 Explorer and when the air temp gets over 100 it stalls. It sounds like it starves for fuel. The fuel pump was replaced. A year or so. Ago but it sat. For a year I replaced the fuel filter.

I have a 2005 mk4 gli and the other morning I went out to start my car for work and all I got was crank no start. I then realized my fuel pump wasn't priming when I opened the driver door. After work I came back and checked the fuel pump fuse and swapped the relay with another I had, still nothing. A buddy of mine came to me and decided to check the connector at the fuel pump for power, using a power probe I believe he hit all or the majority of the wires with 12v of negative and/or positive power. He then unplugged the connector and plugged it back in and the car fired right up. But I noticed that my fuel gauge, engine temp gauge, and outside air temp readout were all not functioning.

Check engine light with code 0125. This code indicates low coolant temp for closed loop fuel control. Well I have changed the thermostat, engine temp sensor and new coolant. After driving approx. 5 miles the light came on again.

1996 Dodge Grand Caravan, 3.3 L engine. When the outside temp is a good range (50 degrees F & above) there is no problem starting. But when it gets below 40 deg. F and really chilly outside temp, I still have strong battery power, but when I switch on the ignition, I don't hear the normal fuel pump activation swirl sound and does not crank - simply silent click. Then I can wait when the outside temp improves and cranks up no problem.

My '04 Passat 4Motion (station wagon) engine coolant temperature gauge, fuel gauge, and outside temperature display all stopped working in the same time. Interestingly enough, car has 32K miles and just ran out of manufacturer warranty 2 months ago.
What could be happening? Should I be checking fuse box or this may be related to some more serious failure?

How to step by step adjust the low beams. I looked at trying to do this and haven't got a clue. Do you need to remove the whole lighting unit or is there an adjustment screw you get to by feel, because you aren't getting in back of the light assembly from the engine compartment, maybe remove the wheel well guards? I think i'm in the market for a service manual. My motto is If it aint broke...........fix it until it is!!!!!

My son's 97 GA with 3.1 has been throwing trouble code of 0420 and my OTC monitor say it is a "TWC System Low Efficiency". What a TWC is or what or where to start checking.

My mother just bought a beautiful 2002 Passat 4motion Wagon.
But, the only thing we can't figure out is the automatic seats...
She adjusted them for her driving, then I adjusted them for my driving, then she adjusted them again, then they adjusted to some weird setting when she unlocked the door!!
What we'd like to do is have it so that:
It defaults to her setting regardless, unless a button is pressed for something else. How do we set that?

When I have it set to comfort, it will adjust up and down at just about every other redlight. Also when I get out sometimes the front will go down. Not leaking or anything there is a electro-mecanical type noise heard and both sides of the front go down the same amount. Is this normal?
