Tire Pressure Indicator Sensor Replacement

Removal Procedure

1. Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle.

2. Remove the tire and wheel assembly.

3. Dismount the tire from the rim.


Tire Pressure Monitoring System

NOTE: Never fit the tire pressure indicator sensor on unapproved wheel rims.

NOTE: Whenever the tire will be removed from the rim, install a new valve stem and a new bolt. Do not reuse the old parts.

Remove and DISCARD the bolt (1) from the tire pressure transmitter (2) and pull it straight off the tire pressure valve stem (3).

CAUTION: Do not scratch or damage the clear coating on aluminum wheels with the tire changing equipment. Scratching the clear coating could cause the aluminum wheel to corrode and the clear coating to peel from the wheel.

5. Remove and DISCARD the tire pressure valve stem by pulling it through the rim.

Installation Procedure


Tire Pressure Monitoring System

NOTE: Illustration shows tire pressure transmitter in final installation position.

Before installation, verify the orientation of the tire pressure valve stem (1) for the correct position of the tire pressure transmitter (2).


Tire Pressure Monitoring System

Remove the NEW bolt (3) from the NEW tire pressure transmitter (2) and pull it straight off the NEW tire pressure valve stem (1).

3. Apply tire soap to the rubber portion of the valve stem (1).


Tire Pressure Monitoring System

Using a tire valve stem mounting tool, pull the valve stem through in a direction parallel to the valve hole on the rim.


Tire Pressure Monitoring System

NOTE: Ensure the flat of the valve lines up with the flats of the snap in the enclosure.

Assemble the tire pressure transmitter (2) to the NEW valve stem (3) and install the NEW bolt (1).

CAUTION: Fastener Caution

6. For rubber valve, tighten the bolt to 1.4 N.m (12.4 lb in).

7. For metal valve, tighten the bolt to 9 N.m (80 lb in).


Tire Pressure Monitoring System

Check the valve stem (1) for correct seat on the rim (2).

  • The rim hole edge has to be completely in the notch of the valve stem.
  • The valve and the rim hole have to be concentric.


Tire Pressure Monitoring System

Make sure that there is a gap between the valve stem (1) and the tire pressure transmitter (2).

NOTE: The tire should not have contact with the tire pressure indicator sensor during installation to prevent a damage of the tire pressure indicator sensor.

10. Mount the tire to the rim.

11. Inflate the tire to the specified pressure as stated on the tire placard.

12. Install the NEW dust cap.

13. Install the tire and wheel assembly.

14. Learn the tire pressure indicator sensor.

15. Lower the vehicle.


Special Tools

  • EL-50448 Tire Pressure Monitor Sensor Activation Tool

Learn Mode Description

The tire pressure monitor system uses the instrument cluster, body control module (BCM), 4 radio frequency transmitting pressure sensors, remote control door lock receiver (RCDLR) and the serial data circuit to perform the tire pressure monitor learn mode functions. The sensor learn procedure must be performed after every tire rotation, BCM replacement, or sensor replacement. Once the Learn mode has been enabled, each of the sensors unique identification codes can be learned into the BCM memory. When a sensor ID has been learned, the BCM sounds a horn chirp indicating the sensor has transmitted its ID and the BCM has received and learned it. The BCM must learn the sensor IDs in the proper sequence to determine correct sensor location. The first learned ID is assigned to the left front location, the second to right front, the third to right rear and the fourth to left rear. The turn signals will individually illuminate indicating which location is to be learned in the proper sequence.

Sensor Functions Using EL-46079, EL-50448, or Equivalent

Each sensor has an internal low frequency coil. When the tire pressure monitor special tool is used in activate mode, it produces a low frequency transmission that activates the sensor. The sensor responds to a low frequency activation by transmitting in Learn Mode-Remotely Triggered.

Learn Mode Cancellation

The Learn mode will cancel if the ignition is cycled to OFF or if more than 2 minutes has elapsed for any sensor or 5 min overall has elapsed to match all four sensors. If the relearn mode is cancelled before the first sensor is learned, the original sensor IDs will be maintained. If the relearn mode is canceled after the first sensor is learned, the following will occur:

  • All stored sensor IDs will be invalidated in the BCM memory.
  • If equipped, the driver information center will display dashes instead of tire pressures.
  • DTC C0775 will be set.

These conditions will now require the Learn procedure to be repeated for the system to function properly.

Tire Pressure Monitor Learn Procedure

NOTE: In the event a particular sensor is activated and the horn does not chirp, it may be necessary to rotate the wheel so that the valve stem is in a different position due to the sensor signal is being blocked by another component. Make sure the TPM tool battery is sufficient to complete TPM learn process. Do not place the TPM tool directly on the valve stem. The TPM tool should be placed against the tire sidewall near the valve stem. The TPM sensor learn activation procedure may have to be repeated up to 3 times before determining a sensor is malfunctioning.

1. Apply park brake (manual transmission only).

2. Ignition On/Vehicle in Service Mode, using a scan tool or driver information center buttons (refer to owners manual), initiate the Tire Pressure Sensors Learn mode. A double horn chirp will sound indicating the Learn mode has been enabled. The left front turn signal will also be illuminated.

3. Starting with the left front tire, activate the sensor by holding the antenna of the tire pressure monitor special tool aimed upward against the tire sidewall close to the wheel rim at the valve stem location. Press and release the activate button. Ensure that the transmit indicator on the special tool indicates that the sensor activation signal is being transmitted. Wait for a horn chirp. If the horn does not chirp, repeat the sensor activation sequence with the tool. Once the horn chirp has sounded, the sensor information is learned and the turn signal in the next location to be learned will illuminate.

4. After the horn chirp has sounded and the right front turn signal is illuminated, repeat step 3 for the remaining 3 sensors in the following order:

  1. Right front
  2. Right rear
  3. Left rear

5. When the left rear sensor has been learned and a double horn chirp has sounded, the learn process is complete and the BCM exits the Learn mode.
