Tire pressure warning flashing light bypass Disable Tire Pressure Sensors?That's the only choice that comes to mind. Hopefully the TPMS has its own circuit. Here is how you bypass the Tire pressure warning light Under the passenger glove box there is a plastic cover, remove the screw (1) and pull down you going to see a little green box (tire pressure monitor ECU) it has plug with 16 wires look for the #6 (when you unplug and looking at the plug in front of you start #1 top left corner and #9 should be right below that. Anyway it's the blue wire you need to cut and ground the wire leaving the box not the one going to the little box and the light goes off even with one of your OEM wheels and tires flat . I didn't have to do it on my GX when I got new 22" wheel. Don't know why it didn't goes off. Ssve me the trouble of doing the bypass, But it will work. I tryed on a friend GX with no problem. It won't help with the right foot, but the foot rest on Here is what Peter did but with a pic.

Tire Pressure sensor bypass any ideas why my sensor didn't goes off? I know it work cause last week the temperture drop below 20 and it went off. Put air in and it goes away. Now put new wheel on and it didn't goes off. I don't really understand your ? the way my is set up is disable with the OEM wheels or aftermarket wheels . what about the gs300???? i am having the same dilema... thanks man!...did you put the stock wheels back when you took it to the dealer???..co'z mine turned on while i was driving on the highway ...also i noticed one time..it was foggy and the darn thing did not show up( i mean no light or nothing) im talking about the whole without a problem,.and soon i pulled into my driveway.the freakin thing came on...lols.....oh wellThe Tire Pressure Monitoring system (TPMS) on the 2007 & 2008 Ford F150 is similar to that used on many other late model Ford models. The TPMS system has pressure sensors inside each tire. The sensors are mounted in the drop center area of the wheel and are located 180 degrees opposite the valve stem.

The sensors are held in place with a steel band that wraps around the inside of the wheel. The sensors generate a radio frequency signal every 60 seconds when the vehicle is traveling faster than 20 mph. The sensors do not transmit a signal if the vehicle is not moving, and they go into "sleep mode" when the vehicle is stopped for 30 minutes or more to conserve battery life. The signal from the tire pressure sensors is received by the Vehicle Security Module (VMS). If a tire is low, the VMS turns on a "Low Tire Pressure" warning lamp and/or displays a "Low Tire Pressure" message on the instrument cluster message center (if equipped). The TPMS system on Ford F150�s with the same tires front and rear is not affected by wheel and tire rotation. But on models with different sized tires front and rear (and different tire pressures), the system must be given a relearn procedure if the tires are rotated. If the TPMS warning light comes on, it could indicate one of the following:

If the TPMS warning light flashes for 70 seconds, then remains on steady:Air Conditioner Cleaner Mold If you have a scan tool that can read body codes, plug the scan tool into the diagnostic connector under the steering column. Garden Bench Cushions Made To MeasureAny of the following are TPMS codes:When Does Lowes Put Patio Furniture On Sale B106A - Faulty Pressure Sensor Signal (range bit) B106B - Low tire pressure sensor battery B2477 � Vehicle Security Module not configured correctly B2868 � Left Front Tire Pressure Sensor Not Found (requires VSM relearn procedure) B2869 � Right Front Tire Pressure Sensor Not Found (requires VSM relearn procedure) B2870 � Right Rear Tire Pressure Sensor Not Found (requires VSM relearn procedure)

B2871 � Left Rear Tire Pressure Sensor Not Found (requires VSM relearn procedure) B2872 � Tire Pressure Sensor Fault (activate sensors with tool and do VSM relearn procedure) C2780 � ECU in manufacturing mode (requires VSM relearn procedure) An electronic tool is needed to activate the individual TPMS sensors. This requires the Ford 204-363 TPMS tire sensor activation monitor, or similar aftermarket TPMS activation tool. The tool is positioned near the tire 180 degrees across from the valve stem. Pressing a button on the tool sends out a signal that wakes up the sensor and causes the sensor to broadcast a pressure signal. The sensor may take up to 6 or 7 seconds to wake up once it has been activated. VEHICLE SECURITY MODULE RELEARN PROCEDURE The VMS training procedure has a time limit of two minutes between sensor inputs. If the VSM does not recognize any of the four TPMS sensors during the procedure, the horn will beep twice and the message center (if equipped) will display TIRE NOT TRAINED REPEAT.

You will then have to repeat the entire training procedure. To enter the TPMS/VMS training mode: Turn the ignition switch to the OFF position, then press and release the brake pedal. Cycle the ignition switch from the OFF position to the RUN position 3 times, ending in the RUN position. Press and release the brake pedal. Turn the ignition switch to the OFF position. Turn the ignition switch from the OFF position to the RUN position 3 times, ending in the RUN position. NOTE: The horn will sound once and the TPMS indicator will flash if the training mode has been entered successfully. If equipped, the message center will display TRAIN LF TIRE. The learning sequence is Left Front (LF) tire, then Right Front (RF) tire, then Right Rear (RR)tire, and last the Left Rear (LR) tire. When the training procedure is complete, the message center (if equipped) will display TIRE TRAINING COMPLETE. If your truck does not have a message center, successful completion of the training procedure will be verified by turning the ignition switch to the OFF position without the horn sounding.
