RESET TIRE PRESSURE SENSOR ON 2009 FORD CROWN VIC
You should not need to reset anything. One of the sensors mounted in the wheel has a low battery. The sensor only operates while the wheel is spinning. The system resets itself with the ignition off for a long time. If you turn on your car in the morning after its been sitting all night and right away you get a low tire warning before driving, something is wrong. It's a system problem because the sensors don't transmit if the car hasn't moved. If it comes on after a lot of continuous driving, it is a low battery. If it comes on in the first 1/4 mile its a dead sensor battery. This all assumes your tire pressure is correct.
Whenever you replace your tires you should replace your TPMS sensors. You or the previous owner chose not to do that to save a few bucks. Later Crown Victorias used stem type TPMS sensors. All others including all Police Interceptors through 2011 used band type TPMS sensors. The band type are better for rough use vehicles where the exposed valve stem might get damaged. As long as the frequency is the same, the sensors are interchangeable. The batteries can not be replaced
The fix for a bad sensor is to go to a tire repair shop, have them use a tool to scan the sensors to see which one is low or plug into your OBDII. Have them replace the sensor with either type. Drive away. The light should go out within 1/4 mile...unless you have more bad sensors.
How do I reset the
Ensure all tires are at right pressure. check owners manual, there is usually a process in thee for it.
When applying brake,engine goes to full throttle,kept brake petal pressed hard.Goes back to normal after about 15 seconds.
Vehicles have what is known as a TPS Sensor. Throttle Positioning Sensor. When these go out you will experience these kind of symptoms. The vehicle is confused on how much throttle to give the car. It's not the way it was a long time ago - that cable from your gas pedal connects to the TPS and when it goes out that's what happens. Other symptoms will include dying on takeoff, smaller surges - going over a speed bump for instance - you'll hit the brake but the car will surge. If you've noticed any symptoms like that, this may be where your problem is. You have to get the car scanned by someone with a code reader. You can purchase the small, standard code reader from Advance for around $50 - which isn't cheap...but neither is getting a car that won't start to the parts store or garage for them to run code - and I can walk you through reading the code. It's literally plugging it in, turning the key on and then reading/resetting the codes. By scanning - if it's your TPS it will usually have a code.
Sometimes, though - like with a Ford Fusion - the problem is so short lived that the computer doesn't store the code for future reference because the system looks at it like an anomaly - that is, not a big enough problem to call home. In this case - you'll have to have a little bit better of a scanner - one that will read in real time. SO you can plug it in, drive around and if the problem pops up - you'll see it before the computer throws the message in the trash. Here's what the standard pocket scanners look like -

No cold air inside the car
try rechecking the blend door actuator and its connections, fuse, etc. also if your AC system is overcharged it will blow warm air.
