Just got new rims put on my tacoma. from reading other similar problems my guess is they didn't put the same valve stems back containing the pressure sensor transmitters. Any way to just shut off the pressure sensor light and use the old fashioned way.....my eyes! Appreciate the help.

Hi, if you are referring to the tire pressure sensors they are actually the valve stems that you put air into the tire with, the sensor is inside the tire and it is not able to be taken out without taking the tire off of the rim and removing the sensor and installing a standard valve stem. But if you remove the sensor your little tire warning light will stay on. Good luck
Iwould check the oil now i have knowen people who have there oil changed and the shpos didn,t put any oil back in or didn,t put enough in these 10 minute oil change places If its not it could be a false reading oil pressure sending unit or connection issue with gauge or sensor
Hello Sandra. Your Impala was originally equipped with a sensor that goes on each wheel to read the air pressure within it. The sensors are part of the valve stem where you put the air in. Each wheel is identified by a receiver inside your car that is able to tell you if the pressure has gone too low. When you had your wheels changed the valve stems were not transferred to your new rims or they were damaged if they were. In order to repair your situation the stems will need to be replaced by the ones on your other rims or new ones. If you opt for new sensors they will need to be programmed so your onboard receiver will recognize them. If you use your originals they will need to be placed at the same position as they were before. If they get mixed up it will not be able to determine which wheel is low. I hope this answers your question. If not, leave a question in comments and I will respond.
Does the compressor run? Low side could be high without a running compressor.
A running compressor? The expansion valve itself is about $50 and bolts in. You will have to remove the 134a gas before installing a replacement expansion valve and vacuum the system before recharging.
Usually this is a bit of dirt in the engine plugging the oil port that supplies pressure to the variable valve timing control cam. Change your engine oil every 3000 miles and maybe switch brands. I had this problem on my Matrix until I switched to Castrol GTX 5W30 that cleaned the oil port right out.
If your vehicle has the silver-metal valve cores (as opposed to black rebber), the tire pressure light goes out once the tires are at or above the minimum inflation pressure. Note that the SPARE is also checked for proper inflation by the system. What I would do is check the spare for proper inflation. If it is low, resetting it should cure your problem. If the light does NOT go out, the dealer who put the tires on may have damaged your tire pressure sensor. To check that, you need a Toyota technician to check the output of your 5 sensors with their tire pressure sensor diagnostic tool. If one is not reading, I would take the vehicle back to the tire guy & make him buy you a new one, They are not cheap.
Hope this helps.
If you have the silver-metal valve cores, on the rims, there is NO reset proceedure. Under the valve cores is a transmitter, which is battery powered. It sends a "yes/no" signal to the tire pressure ECM. Note that ALL 5 tires transmit to the ECM. The signal is "at or above" the specific target pressure needed, or is is below the target pressure. What to do: get a GOOD tire pressure gauge, not those cheap ones that look like pencils. Set the tire pressures to the specification, INCLUDING the spare. Your light should go out. If not, there is the possibility that one of the sensors is innoperative, and that will involve a trip to the dealership, to get it replaced under warranty. Try the tire pressure resetting, adn don't forget the spare. Get back to me if this works. Glad to help, and thanks for choosing FixYA.
