Thread: 2007-10 Toyota Camry TPMS reset

  1. #1

    2007-10 Toyota Camry TPMS reset

    UBJECT VEHICLE: 2007-10 Toyota Camry.

    SENSOR IN TIRE? No, the TPMS sensors are mounted in the wheels.

    RESET PROCEDURE? Yes. Directions follow.

    SPECIAL TOOLS NEEDED? Yes, a hand-held tester.

    The tire pressure monitoring system (TPMS) on the Toyota Camry model years 2007-10 is designed with a TPM valve sub-assembly. The sub-assembly contains a tire pressure sensor/transmitter installed in each tire/wheel assembly.

    The sensor measures the internal tire pressure and temperature. These measured values and transmitter IDs are transmitted to the tire pressure monitor receiver assembly on the body via radio waves. This data is then sent to the tire pressure monitor electronic control unit (ECU) from the tire pressure monitor receiver.

    To remove an old sensor and install a new one, follow these steps.

    Demount the tire from the wheel using the tire changer manufacturer’s instructions.

    NOTE: When a tire, wheel, tire pressure sensor and/or tire pressure monitor ECU are replaced, the sensor ID must be memorized by the tire pressure monitor ECU.

    If the tire pressure valve sub-assembly is going to be replaced, make a note of the seven-digit number (transmitter ID) before installation. It cannot be seen after the sensor is installed.

    Whenever a new sensor is installed, it will need to be registered in the tire pressure monitor ECU.

    1. When replacing a wheel or tire, tire pressure sensors must be set up in one of the following ways:

    a. Remove the sensor from the old wheel and install it in the new wheel.

    b. Keep the tire pressure sensor mounted in the wheel, and replace only the tire.

    c. Use a new wheel and sensor.

    2. Remove the wheel. Next remove the cap and valve core, and release the air from the tire (see Figure 1). NOTE: Keep the removed cap, valve core, nut and washer for re-use.

    3. After ensuring that air is sufficiently released, remove the nut and washer that is used to hold the tire pressure monitor valve sub-assembly and drop the sensor inside the tire. NOTE: Be careful not to damage the tire pressure monitor valve sub-assembly by allowing it to get between the tire bead and the wheel or shoe during demounting.

    4. After dropping the tire pressure monitor valve sub-assembly into the tire, disengage the bead using the shoe of the tire remover.

    5. Remove the tire bead on the upper side following the usual removal procedure.

    6. Take out the sensor from the tire, and remove the bead on the lower side following the usual procedure. NOTE: Check that no cracks or damage are visible on the grommet. If so, replace the grommet together with the washer and nut. When disposing of the sensor, remove the battery and dispose of properly.

    7. Remove the inner grommet from the tire pressure monitor valve sub-assembly, or retrieve from the wheel, if necessary.

    Initialize, then register

    During initialization, the tire pressure monitor valve sub-assembly measures the inflation pressure of the tires, and registers the signals that are transmitted into the tire pressure monitor ECU at a frequency of one per minute.

    The initialization process is completed when the signals from the four tires have been received.

    The initialization process is cancelled if the ignition switch is turned to the OFF position prior to the completion of initialization. To restart initialization, the tire pressure warning reset switch must be pressed again.

    1. Set the tire pressure of all wheels to the pressure specified on the tire and loading information label.

    2. With the vehicle parked in a safe place, connect the intelligent tester to the DLC3 and turn the ignition switch to the ON position.

    3. Turn the intelligent tester ON and navigate to the TIREPRESS option using the on-screen prompts.

    4. Within 30 seconds of turning the ignition ON, press and hold the tire pressure warning reset switch (located at the left side of the glove compartment opening) until the tire pressure warning light blinks three times at one-second intervals.

    5. Wait two to three minutes with the ignition ON, for the initialization process to complete. If the initialization has not been completed successfully, Diagnostic Trouble Code C2177/77 is set in the tire pressure monitor ECU 20 minutes after driving starts.

    6. Confirm that initialization is complete by verifying that the correct tire pressure values are displayed on the intelligent tester.

    When a tire, wheel, TPM valve sub-assembly and/or TPM ECU are replaced, the transmitter ID needs to be registered in the tire pressure monitor ECU with a Toyota hand-held tester. To register a transmitter ID, follow these steps.

    1. Set the pressure of all the tires (including the spare tire) to the pressure specified on the vehicle’s tire and loading information label.

    2. Connect the hand-held tester to DLC3.

    3. Turn the ignition switch to the ON position.

    4. Select REGISTER from the UTILITY menu.

    5. Enter the transmitter ID using the hand-held tester and transmit it to the tire pressure monitor ECU.

    6. Set the ID transmission condition to “ID registration is complete.” NOTE: If steps 4-6 are not completed within five minutes, the mode will return to the normal operation mode.

    To install a new sensor, follow these steps.

    1. Insert the tire pressure monitor valve into the valve installation hole. Insert from the inside of the rim so that the print surface can be seen.

    2. Install the washer on the tire pressure monitor valve from the rim side, and tighten the nut to 35 in.-lbs. Check for the following:

    a. Ensure there is no foreign matter on the washer and nut.

    b. If the tire pressure monitor valve was removed, check that there is no damage or cuts, and no foreign matter such as mud, dirt or sand on the grommet. Replace the grommet with a new one if any of these defects are found.

    c. Check that there is no oil, water or lubricant around the rim hole, tire pressure monitor valve, washer and nut. Failing to do so may result in improper installation.

    3. Set the wheel disc to the mounting machine, and install the lower tire bead.

    4. Making sure that the tire bead and tool do not interfere with the main body of the sensor, and that the sensor is not clamped by the bead, install the upper bead.

    5. When putting air into the tire, be careful to position the tire pressure valve squarely on the stem of the tire pressure warning valve and transmitter.

    6. After the tire is inflated, the valve nut may be loose. Retighten the nut to the specified torque, and then check for air leaks with soapy water.

    7. Install the tire and wheel assembly.

    8. When a new sensor is installed, the ID code will need to be registered

    Hi TPMSProAlbert, this is really quite detailed and useful information. I have a question and would like to have your opinion on this. Yesterday, I got 4 new tires installed at a local Sears Auto Center (just replaced all the four original tires on my 2007 Camry LE, 4 Cyl.). When I got the car back after the tires were installed, I had the TPMS indicator come on and didn't turn off on its own. I asked the service rep and he told me that it would go away after I drive around 25 miles or so. Although I haven't driven for 25 miles after the installation of the tires, I am not sure if the indicator is going to go away. Do you have any idea as to why would it take around 25 miles of driving for the indicator to go off?

    Hello and welcome to the forum. Many vehicles do have a set mileage that needs to be driven before the system will reset. Some of it has to do with the recalibrating of the wheel speed sensors and or the new tire pressures. It is normal with most import vehicles.
