TPMS: Honda CR-V 2007-2013
SUBJECT VEHICLES: 2007 to 2013 Honda CR-V.
RELEARN PROCEDURE? Yes.
SPECIAL TOOLS NEEDED? Yes. The Honda diagnostic system (HDS) or an OBD-II compatible scan tool and an ATEQ VT55 tool (recommended), or the TPMS sensor tool AKS0620006 must be used to program information into new TPMS control unit with both of the reset procedures. The TPMS sensor tool (AKS0620006) has been superseded by the ATEQ VT55 tool, and is recommended for use on all Honda vehicles.
NOTE: When a tire pressure sensor or control unit is replaced on a 2007-2013 Honda CR-V, or a known-good wheel is substituted, the ID(s) of all four tires’ sensors must be memorized by the TPMS control unit. After memorizing the sensor ID(s) or doing a tire rotation, the mounting location of sensors 1, 2, 3 and 4 must be determined. See reset procedures.
Whenever the vehicle speed exceeds 28 mph, the tire pressure monitoring system (TPMS) control unit in 2007 to 2013 Honda CR-Vs monitors all four tires and the system itself. If it detects less than 24 psi (168 kPa) in a tire, it alerts the driver by turning on the low pressure indicator and setting a diagnostic trouble code (DTC) in the control unit. When the tire pressure is increased to more than 28 psi (190 kPa) and the vehicle is driven above 28 mph, the control unit will turn off the indicators and store the DTC(s).
If a problem is detected in the system, the TPMS indicator will come on. If low tire pressure and a problem in the system are detected, only the TPMS indicator comes on.
When the system detects a problem, the TPMS control unit sets a code, but shifts to fail-safe mode, and does not alert the driver to low tire pressures. If the TPMS control unit loses power or fails, the TPMS indicator will come on, but no DTC will be set. Each sensor is an integrated unit made up of the tire valve stem, a pressure sensor, and a transmitter. The unit is attached to the inside of the wheel, around the valve stem. Each low pressure sensor has its own ID to prevent jamming by similar systems on other vehicles.
After memorizing all the sensor ID(s), the control unit receives only those specific signals. Sensor memorization after normal tire rotation is not necessary.
Tire pressure monitor warning indicators
NOTE: Tire pressures will increase slightly as the temperature in the tires rises during driving at highway speeds. Pressures will also increase or decrease slightly with changes in outside air temperature. A temperature change of about 18 degrees Fahrenheit (10 degrees Celsius) will change tire pressure by about 1.5 psi (10 kPa). If the temperature drops and then rises, tire pressure could decrease just enough to turn on the low pressure and tire(s) indicators, but later increase enough to turn them off. To resolve a complaint of such intermittent indications, confirm and clear the stored DTC(s) and check the tire pressures. Then explain to the customer how temperature changes can affect the system, especially when tire pressures are near the low end of the TPMS normal range — 24 to 32 psi (168 to 220 kPa).
NOTE: If the outside temperature is at or below -40° F (-40° C), the system may not function properly. If low tire pressure indicator is lit continuously, due to low pressure in one or more tires, adjust tire inflation to proper pressure as indicated on the tire and loading information placard. The light will remain on until tire pressure is properly set. If the warning light is still lit, or the TPMS indicator is lit continuously, there is a problem in the TPMS. See the appropriate manufacturer service information. If a problem is detected in the system, the TPMS indicator will come on. If low tire pressure and a problem in the system are detected, only the TPMS indicator comes on. When the system detects a problem, the TPMS control unit sets a code, but shifts to fail-safe mode, and does not alert the driver to low tire pressures. If the TPMS control unit loses power or fails, the TPMS indicator will come on, but no DTC will be set.
NOTE: If a flat tire is replaced with the spare tire, the TPMS indicator will come on, and DTC(s) will be set, because the system is no longer receiving the signal from the flat tire’s transmitter. This does not indicate a problem with the spare tire.
NOTE: When a tire pressure sensor or control unit is replaced, or a known-good wheel is substituted, the ID(s) of all four tires’ sensors must be memorized by the TPMS control unit. See memorizing sensor ID. After memorizing the sensor ID(s) or doing a tire rotation, the mounting location of sensors 1, 2, 3 and 4 must be determined. See sensor location.
When the tire pressure warning light illuminates and a warning message appears, immediately check air pressure of all tires and adjust to the specified pressure. Drive the vehicle above 28 mph (45 km/h) for a few minutes. Ensure that the warning indicators go out.
Tire pressure sensor registration
NOTE: The Honda Diagnostic System (HDS) or an OBD-II compatible scan tool and an ATEQ VT55 tool (recommended), or the TPMS sensor tool AKS0620006 must be used to program information into new TPMS control unit with both of the reset procedures. The TPMS sensor tool (AKS0620006) has been superseded by the ATEQ VT55 tool, and is recommended for use on all Honda vehicles.
NOTE: To ensure the control unit memorizes the correct ID, the vehicle with the new sensor must be at least 3 m (10 ft.) from any other TPMS pressure sensor not installed on that vehicle.
Memorizing sensor ID
NOTE: When doing a tire rotation, memorizing the sensors is not needed. NOTE: Let the vehicle sit for at least five minutes to allow the tire pressure sensors to switch to sleep mode.
1) With the ignition switch in OFF position, connect the HDS to the 16-pin Data Link Connector (DLC) located under the left side of the dashboard.
2) Turn the ignition switch to ON position, and verify that HDS is communicating with the TPMS control unit.
NOTE: If “Not Defined” displays on the HDS, turn the ATEQ VT55 OFF, rotate the tire 1/4 turn, turn ON the initializer, and try to initialize again. Repeat this procedure until a response is shown.
NOTE: If the vehicle’s ignition switch is turned OFF before all sensors are memorized, the memorizing ID is canceled.
3) Hold the ATEQ VT55 tool (recommended), or the TPMS sensor tool AKS0620006 near one wheel, and memorize the pressure sensor ID by following the screen prompts on the HDS. If the TPMS control unit is still having trouble learning ID(s), refer to the appropriate service information.
4) Repeat the last step for each wheel until all four sensor ID(s) are memorized. When all are memorized, the low tire pressure indicator will blink.
5) Turn the ignition OFF.
6) Test-drive the vehicle at 28 mph or more for at least three minutes. Monitor the low pressure indicator to be certain it does not blink.
NOTE: If it has been more than five minutes since the end of the last test drive, the tire pressure sensors will need to be reactivated with the ATEQ VT55.
7) Turn the ignition switch OFF, reduce the pressure in one tire until it is below 24 psi, then turn the ignition switch ON.
8) Test drive the vehicle at 28 mph or more for at least one minute.
9) Verify that the low pressure indicator turns on, and then re-inflate the tire.
10) Repeat steps 7 through 9 for all other tires. Clear any DTC(s) with the HDS.
1) With the ignition OFF, connect the HDS to the 16-pin data link connector (DLC) located under the left side of the dashboard.
2) Turn the ignition switch ON, and verify that HDS is communicating with the TPMS control unit.
3) Follow the prompts on the HDS to activate the tire pressure sensors using the ATEQ VT55 tool (which is recommended), or the TPMS sensor tool AKS0620006. Start with the left front (LF) wheel. Initialize the vehicle’s wheels in the following order: left front (LF), left rear (LR), right rear (RR), and right front (RF).
4) Check the HDS screen, and note the active sensor reception order of tire pressure sensors 1, 2, 3 and 4.
5) Note the sensor location for future reference.
6) Turn the ignition switch OFF.
CAUTION: The tire should be demounted from the wheel using the tire changer manufacturer’s instructions. Use the following information to avoid damage during the demounting/mounting procedures.
NOTE: When a tire pressure sensor is replaced, the sensor ID must be memorized by the TPMS control unit. See reset procedures.
NOTE: Vehicles equipped with a TPMS must use wheels made for the system, or the system will not work. On all models, a “TPMS” mark is visible on the wheel, and a counterweight is cast into the opposite side of the spoke to balance the weight of the sensor.
Tire pressure sensor
CAUTION: Fluid sealant used to repair a punctured tire can damage the tire pressure sensor mounted on each wheel. It can prevent the system from detecting the correct tire pressure and set a DTC even though the system is normal.Removal
1) Raise the vehicle, and support it with safety stands in the proper locations.
2) Remove the wheel with a faulty sensor.
3) Remove the tire valve cap and valve core, and let the tire deflate.
4) Remove any balance weights, and then remove the tire from the wheel with a commercially available tire changer. Note these two items listed below to avoid damaging the tire pressure sensor:
- Do the outside of the wheel first.
Position the wheel as shown so the valve stem is 90 degrees from the bead breaker (see Figure 1).
- Do not position bead breaker of tire changer too close to the rim.
Position the wheel so the tire machine and tire iron are next to the valve stem, and will move away from it when the machine starts. Then remove the tire from the wheel (see Figure 2).
5) Remove the valve stem nut and washer, and then remove the tire pressure sensor with the valve stem from the wheel. If the valve stem nut cannot be removed by hand, spray valve stem with rust penetrant, and then carefully remove the nut with pliers. NOTE: The valve stem grommet might stay in the wheel; make sure to remove it.
6) Remove and discard the valve stem grommet from the tire pressure sensor (see Figure 3).
NOTE: Use a new nut, valve stem and screw.
1) Before installing the tire pressure sensor, clean the mating surfaces on the sensor and the wheel.
2) Install the tire pressure sensor and washer to the wheel, and tighten valve stem nut finger tight. Make sure the sensor is resting on the wheel (see Figure 4).
NOTE: Do not use air or electric impact tools to tighten a valve stem nut.
3) Tighten the valve nut to 35 in.-lbs. (4 N.m) while making sure to hold the tire pressure sensor toward the wheel.
4) Lube the tire bead, and position the wheel so the tire machine and tire iron are next to the valve stem and will move away from it when the machine starts. Then install the tire onto the wheel (see Figure 2).
NOTE: Make sure the tire bead is seated on both sides of the rim uniformly.
5) Inflate the tire to 44 psi (300 kPa) to seat the tire bead to the rim, and then adjust the tire pressure to specification as indicated on the tire and loading information placard, and install the valve stem cap.
6) Check and adjust the wheel balance, and then install the wheels to the vehicle.
7) Remove the safety stands, and lower the vehicle.
8) Memorize the pressure sensor ID(s) — see reset procedures.
Component Ft.-lbs. (N.m)
Wheel nut 80 (108)
Tire pressure sensor nut 1 35 (4)
Do not reuse any nuts that have been tightened (even one time) to the specified torque, as they are deformed inside. Do not use air or electric impact tools to tighten a valve stem nut.
Tightening the nut beyond the specified torque can damage the nut. You may hear a snap or pop as you tighten the nut (this is normal).
Make sure that there is no space between the sensor and the wheel.
