2008 Nissan Maxium keeps losing air in tires as soon as it gets cold

There Are Cars That Require New Air Pressure Sensors When Replacing Tires. Wal-Mart Does Not Offer That Service. Just Tires, Tires Plus Etc Can Help You

Trouble Code: U1000

Controller Area Network Line Malfunction

Possible Causes:


CAN connector is damaged or is disconnectedCAN communication line is open, shorted to ground or to powerOne of the modules is shorted and pulling the CAN voltage low

Air pressure in the tires drops when it is cold (as much a 5 PSI), as you drive they heat up and that makes them fall within the correct pressure limits to turn off the low tire pressure warning. I suggest you get an accurate tire gauge and air your tires up to 32 PSI all around.

Turn the A/C on put on the Rirculation button on (should be a green light). That will give you Maximium cooling. Oh yea. if you put it on fan speed 2 it will give you the coldest air. but if you put it on 4 it will not be as cold but you will get cooeler sooner.

TO RESET LOW TIRE LIGHT.JUST DRIVE VECHICLE 16 MPH TO COMPLETE THE TIRE RESET PROCEDURE.BUT FIRST PUT AIR IN TIRES FIRST.YOU NEED 33 PSI.TIRE PRESSURE.

Tires do lose air pressure when the temperature drops. They should stabilize after a while and ndot need constant service. Don't rely on the tire pressure sensor. Use a good tire gage to determine the need to add air. If you are adding air every few days, I would think you had a slow leak somewhere. Is it all 4 tires or just one. What about the wheels. Are they the original wheels, or customs. Some custom wheels don't seal as well as the originals. If you really are losing air every few days, you might want to consider sealing the tires with a commercial product such as the one called Slime. It's kind of pricey, but works great.

did you check and air up all the tires to the recommended pressure on the decal on the drivers door. I would add 3 psi to that spec...cold.

could be a faulty valve or the matrix is bloked o

our car will do this, if the car is in idle and not reving or in drive the clutch will disingage the ac fan as not to burn it out.....in idle it gets very hot....and usually the air comming across the coils helps to keep the systems cooler....it's a good possibility it's because your car uses the r135 or r134 coolant and not the r12 coolant, they are trying to keep the r12 off the shelves for non industrial use....hope this helps you....shia

if the weather has changed and got cold your tire pressure would have dropped and would be lower. 2 options. 1 is fill ther tire to 30 psi and ride it out (remembering that when it warms up the tire pressure will automatically go up too)
2. Is to run a dry air such as nitrogen which does not change pressure in hot/cold weather.
Hope this helps
