Ford A/C :: Warm Air Started Blowing - Error Code P2195
May 24, 2013
Just the other day my A/C had started to blow hot air, so I looked online and was told to try and re-charge it by a few people so I went and bought a can of that r-134a recharge and as it was on the low port the gauge was not reading like any of the guides I saw, as it did not stay at just one # it would go from 25 then back up to 40+ then slowly back down and just kept going up and down, I am assuming as the compressor was kicking on.
So I did not charge it at all because the PSI said to be in my car at the temp was 45 and if it was doing this but going 25-40 and back I did not want to over fill it.
So then this morning after doing that last night my engine light comes on, but I was told that the a/c will not effect this but I had it checked and I got an error code (P2195) "lack of heated oxygen sensor bank 1 sensor 1 H02S11 switch sensor indicates lean" with a few causes that may be the reason.
Should I go ahead and charge the a/c? will this cel code have anything to do with the a/c? and also why was the gauge changing like that and not at one steady number? Could it be because the car is running hot and maybe I need to check the anti freeze/coolant?

98 e150 - 4.6l, 185k, My air started blowing warm the other day. It worked perfectly fine. I checked the compressor to see if it was turning. Nope! I am wondering if it could be the clutch?
I replaced the alternator and changed the serpentine belt a couple of months ago and noticed a very slight whining sound sometime after I did this. I thought something might be going and just ignored it and said to myself, that's all the new tread in the new belt whining a little. Could be! not sure.
Anyway, where could I possibly start an easy procedure to see why the failure in the compressor not turning? Compressor is a lot harder to get at than an alternator!

My wifes car AC just started blowing warm. I figured it was getting a little low on refrigerant. So I went and bought a can with the gauge on top, and I connected it and it was reading half way into the red zone....way overcharged. But nobody has put any in the system since we bought the car over a year ago. The AC has been great for all this time. So how can it be blowing warm and be overcharged that much without overheating the cars engine ? The clutch is coming on with the compressor?

I have an 05 prius that has been a great car 193,000 miles with no issues, until now. AC started blowing warm air so took it to mechanic who replaced the compressor. Blew cold for a day and started blowing warm again. Took it back to mechanic replaced the evaporator. Same thing blew cold for a day and then warm air next day.
Mechanic told me to take it to Toyota to get it looked at and they said 3 way coolant valve so we replaced that and still blowing warm air. Took it back to Toyota for the second time and they said it was a bad compressor so we replaced that and still no cold air. No AC in Florida summer is getting old fast need to get this fixed.

The A/C on my 2004 Accord has started blowing warm air out of the 2 driver side vents, but still blows cold air out of the 2 passenger side vents. It also occasionally blows condensation out of the 2 cold passenger vents. When this same thing happened last summer, the condenser and compressor were replaced within 3 weeks of each other. It is less than a year later and the same problem is occurring. Even more odd; every once in a while the 2 driver side vents will blow cold for just a few minutes, then revert to blowing warm air. The car does not have dual climate controls.

I own a 06 limited and my Check engine along with VSC lights came on. Autozone read the code and it is a P2195 error. According to AZ the O2 sensor cost $500, according to websites the fix is O2 sensor and manifold ~$1800. I don't have that much money. The dealer told me that it was ok to drive with warning lights on. I checked the MAF sensor and it is clean. The O2 sensor or A/F sensor Stuck Lean - bank 1 sensor 1. If I want to do the work myself, any diagrams, picts, instructions etc......

2007 camry xle 4 cylinder engine, 2.4 liter I'm getting a P2195 code, which is the A/F sensor B1 S1. I have a few questions:
1. Any diagram of the location?
2. I've been trying to figure out the correct part number, so I can search for a replacement. I've found 4 or 5 different numbers already. What is the correct part number?
3. Should I only by the OEM part? Or do the aftermarket brands like Denso work?

So of course it has to happen 3 weeks after my warranty expires. My CEL comes on and I have it read and the result is P0440. I find out that my wife has a habit of topping off the gas tank and so I am thinking that she has probably ruined the charcoal canister. It is something easy to replace?
I have an 06 limited edition... Yes, she will not be topping off any gas tank anymore.

Last week I was on a dive trip and my RX remained parked outside for a week. As I was returning home and I was merging on the highway my CEL appeared; I used my scanner and the code was p2195, which I cleared. My RX was driven for about 5 minutes before merging onto the highway.
On my way home I needed to stop for gas, I filled up and them merged onto the highway and the CEL came on again. I used the scanner and the same code p2195- which I cleared.
I completed my drive home, and have only been doing short city driving since then an no CEL's.

Any resource that I can use to find the part number of the O2 sensor on my wife's 03 v6 Camry.
I have a check engine light, scanned by code scanner to reveal P2195. This OBD code is supposedly sensor 1, bank 1 "stuck lean" which is the upper O2 sensor on the left side of the engine (closest to radiator with transverse mounting).
So it should be easy to change if this is the issue but I'm having a hell of a time finding the right part number. Too many choices.

I have a p2195 trouble code with my 2007 Toyota Sienna CE. This is O2 Sensor Signal Biased/Stuck Lean Bank 1 Sensor 1. I am assuming I'll need to replace this sensor. It's a little confusing but if I am reading my Haynes manual correctly, the repair goes as follows:
The sensor for 2007 and later models will be in the exhaust pipe after the catalytic converter. To remove it, it's necessary to remove the passenger seat, disconnect and snake the pigtail through the grommet in the car floor. Then, disconnect the O2 sensor from underneath the van and replace.

So I just replace my Cat. Converter with all new sensors in them. I just replaced my spark plugs. (I'm knocking out these check engine light problems) and I think I'm getting close to the root as to why these other parts went bad. Why my o2 sensor would be stuck on "lean" ....

I've recently purchased a 2007 Prius and I just noticed few days go that A/C blows warm air (weather was fair when I bought it and I can't remember if it really worked or not then) and middle vents do not blow any air. I'm not sure if two problems are connected but I do want to get both fixed without spending $$$ at the dealership. Where can I start?

I am getting error code po457 Evaporative emissions error, I am told the canister purge valve could be bad.

My 2005 Mustang w/ 4.6L is giving a P0456 code and also won't let me fill it with gas completely. I think I've narrowed it down to the canister vent or purge valve. Looking for narrowing down which would cause the gas fill issue.

Well it's that time of year to start using my air conditioning. Went to use it today and it is blowing nothing but warm air. Worked perfectly last time I used it last year. I thought about buying that 134a ac recharge kit from auto zone.

I'm having issues with my a/c blowing randomly warm air. At idle (stop lights, heavy traffic) the cold air will kick off but the fan will remain constant. Once I'm back up to full speed, the cold air will come back. It also works if I turn the a/c and fan off for a few minutes and turn it back when I'm at highway speed. I've recharged it and when it blows cold it will freeze me out. I'm thinking its a possible compressor issue?

Having problems with the A/C on F150 2006 or newer. It blows warm air while idling. I have taken mine to 2 different dealerships had Ford engineers down and no one can seem to find the problem. I love Ford vehicles but I can't handle this in the these hot summers.

My Ford Explorer blows warm air instead of hot air and it's getting colder and my windows get fogged up. I fixed my clicking sound behind the dash.

To start I have a 1991 super duty with a 7.3 in it. I replaced the evaporator, dryer and orifice tube. I added 4 cans of Freon and the a/c still blew warm so I added another can same result. I put one of the throw away gauges on the truck and it read empty so now I'm mad thinking it all leaked out only other option I could think of was to replace the condenser so went to break the lines to change it and Freon came spewing out so I tightened the lines back up and added another can of Freon still warm.
I got good gauges and hooked them up to high and low sides. High side was reading 100+ and low side was around 100 maybe a little lower. Oh yeah the compressor will come on and go right back off. So I let some of the Freon out and dropped the pressure down to 50 the high side was still a little below 100 so I let a little more out and now there is no Freon in the system again.
The lines never got cold and the dryer stayed warm the whole time. The first time I put Freon in before I started replacing stuff the dryer would get ice cold. My only thought is maybe the compressor is bad but I was told it was just replaced but Freon was never put in it. Oh and when I put the new parts in I replaced the orings in the compressor and put new oil in the compressor.
