Not every car owner knows that driving with high or low tire pressure is not safe. Improperly inflated tires reduce the handling and dynamic performance of the vehicle. In addition, fuel consumption increases and tire life decreases, since they are designed for use at the required pressure. The Toyota Rav 4 tire pressure sensor relieves the owner of all the listed problems.
Why are pressure sensors installed in tires?
The manufacturer recommends a certain operating tire pressure that must be maintained. Then the car is easy to control and is able to maneuver even in difficult weather conditions without problems.
The driver must understand that the compression inside the tires varies with temperature, changes in atmospheric pressure, humidity and other weather conditions. Therefore, it is recommended to check the indicators of each wheel daily with a pressure gauge before leaving and pump it up with a hand pump.
It is much faster and more convenient to check the indicators of the sensors in the wheels.
Facts : By maintaining the required tire pressure, the driver saves fuel. With indicators below the norm by only half an atmosphere, fuel consumption per 100 kilometers increases by 1-1.5 liters.
Pressure sensor - an important device
The Land Cruiser 200 emphasizes the elitism of its owner. Stylish and strict design commands respect. This SUV can often be found in the garages of officials, politicians, and businessmen.
Serious men always choose something powerful that emphasizes their strength. Toyota Land Cruiser Prado meets all the requirements of the stronger sex. This car, like a cruiser, floats along the road, easily overcoming obstacles. He is not afraid of drifts on the roads or muddy mud (within reasonable limits).

Each model range of Toyota cars is equipped with first-class additional options. One of the most useful is the tire pressure monitoring system. It falls into the safety category that needs to be monitored especially closely in vehicles such as SUVs and crossovers.
Recently, car manufacturers have been very concerned about the safety of their creations for consumers. High competition and increasing costs for the development and production of vehicles force industrialists to pay a lot of attention to the functionality of the vehicle in terms of its safety.
Toyota Rav 4
The tire pressure sensor for Toyota Rav 4, Land Cruiser 200 and Prado is installed standard at the manufacturer's factory, so owners do not need to think about their availability when purchasing. But you still need to know why it is needed, as well as how to turn off the pressure sensor or change it.
How do tire pressure sensors work?
The modern Toyota RAV 4 is equipped from the factory with a TPMS tire compression monitoring system. Sensors are installed in each wheel; if there is a deviation from the norm, they send a radio signal to the control unit. In addition to them, the TPMS system includes:
- Antennas (on transmitters and receiver);
- Dashboard display showing data;
- A control unit that receives signals from wheel sensors;
When the compression inside the tires is not normal, the warning light comes on and an audible signal sounds. The signal is triggered for one of the following reasons:
- The pressure in one of the wheels is below or above normal (the installed spare wheel may indicate above normal);
- You installed a wheel without a sensor, or the system did not detect it;
- The battery on the sensor is dead;
- TPMS radio signals have failed. As a rule, they are interrupted by a stronger signal from the outside. For example, the presence of power lines nearby can cause a similar failure; as soon as you move away from the source of interference, the problem will disappear;
- Problems with the TPMS system;
Consequences of incorrect tire pressure
Data on tire pressure standards are indicated by the manufacturer in the vehicle's operating manual.
If the indicators on a particular machine differ from the established norm by 0.5 atm , significant changes in characteristics occur. Low rates lead to:
- deterioration of controllability;
- increased fuel consumption (up to one and a half liters per 100 km);
- rapid wear of rubber (due to increased friction on the road surface).
Recommended tire pressure plate
Exceeding the standard will result in the following:
- driving comfort will decrease (the crossover will become rigid);
- braking distance will increase;
- Various uneven surfaces will damage the tires.
You can avoid the consequences by installing 4 tire pressure sensors on the Rav.
The device will constantly signal the current state of affairs in the wheels.

Tire pressure sensors for Rav 4
Toyota Rav 4 crossovers are equipped with original tire pressure sensors. The catalog number of the devices is 42607-30071 or 42607-02031 . The device is mounted when the tire is installed and connected to the crossover ECU. A signal with information is transmitted to the dashboard. The driver sees numbers that indicate the current state of affairs. If the deviation exceeds the permissible norm, a sound signal is given and a special icon is displayed.
The original sensor for Rav 4 has the following parameters:
- the nipple is made of metal;
- connection using the OBD2 connector (sensor numbers are entered);
- frequency is 315 and 433 MHz ;
- validity period up to 8 years;
- weight – 30 grams.

A device that allows you to monitor the pressure will work if:
- as a result of the difference in ambient temperature in the tire, the atmospheric density has decreased;
- the tire has been punctured and the tire goes flat;
- the wheel was overinflated;
- the tire is excessively worn;
- one of the devices is broken;
- The device malfunctioned.
If you buy non-original sensors, the risk of getting a fake increases. Incorrect information about the state of affairs in tires can lead to an incorrect interpretation of the current situation. The risk increases and traffic safety comes into question.
It is better to install original devices or proven analogues, contact an auto center.
Non-original sensors
Analogues of the original devices on the Rav 4 are produced in England at the Schrader plant. The brand's products are mounted on BMW and Mercedes cars. Schrader markings can be seen on the sensors . Another option is Italsensor . This is the same device, but produced by an Italian factory. The operation of analogues is reliable, so they can be safely installed.
Schrader - tire pressure sensor
Original tire pressure sensors for the Rav 4 crossover are sold under catalog numbers 4260730040, 42607-30071, 4260742021, 42607-02031, 4260750011, 4260750010 . Among the reputable brands supplying analog devices to the market are:

Installing new tire pressure monitoring sensors for Rav 4
Replacing wheels or tires on a Rav 4 involves installing valves and transmitters responsible for pressure.
In addition to installation work, identification codes must be entered into the computer of the monitoring system.
You can contact an official dealer. It is permissible to contact a service center whose employees are qualified and equipped.
New sensors must be registered in the ECU
Initialization
If new tires are larger, an initialization procedure is performed. Moreover, during its implementation, the current pressure indicator is taken as a standard. How is initialization done? The Rav 4 crossover must be placed in a safe place. The ignition key or button is in LOCK state .
The sensor numbers must be registered in the control unit.

It is worth noting that initialization will not be possible while driving. The control is carried out with an eye to the normal pressure in cold tires (i.e. Rav 4 must be maintained without driving until the tires have cooled down). The next steps for final installation of tire pressure sensors:
- The engine switch is set to ON (IGNITION ON) ;
- responsible for resetting the pressure signal is pressed and held This concludes the procedure.
Conclusion
Tire pressure sensors can be installed on Japanese Toyota Rav 4 cars.
Re-installation is required for any replacement of wheels and even tires.
After installation, an initialization procedure is performed. With pressure-monitoring devices, the driver receives a tool that increases traffic safety.

How to properly install a pressure sensor for Toyota RAV4
To install or replace compression sensors in the wheels of a Toyota RAV 4, you need to perform the following steps:
- The machine should be secured with boots to prevent accidental movement;
- Raise the wheel on which the work will be performed with a jack;
- Will place a safety stop in case the jack fails;
- Remove the wheel by unscrewing the bolts securing it;
- Disassemble the tire;
- Release the wheel rim by removing the tire from it;
- Unscrew the valve or non-working sensor;
- Install a new one into the mounting hole for the sensor;
- Place the tire back on the rim and assemble the wheel;
- Inflate the tire;
- Check for air leaks near or through the sensor. If there is a leak, tighten it, but without excessive load;
- Screw the wheel back;
- Pump up to the required parameters;
"Registration" of children's school
In order for the sensor to be detected by the vehicle’s diagnostic system, you must perform the following simple steps:
- Turn on the ignition.
- Press the “SET” button three times.
- Start the engine.
- Drive a car for 5–7 kilometers at a constant speed of 40 km/h.
While driving, a new sensor will be automatically registered. “Registration” will be manifested by the fact that the display will begin to show the pressure in the wheel where the automatic pressure meter was replaced. You can also check the tire pressure by lowering the tire slightly where the new part was installed. If the security system begins to signal an air leak, then the functionality of the new part will be established with 100% probability.
How to reset the tire pressure sensor on a Toyota Rav 4?
There are two ways to reset the readings of all sensors in the RAV 4 TPMS system. The first method is similar to “prescribing”, which is described just above. The second way is this:
- Drive a car for 20 kilometers at a speed of 60-70 km/h;
- Stop the car, turn off the engine;
- Deflate the air in the wheels and inflate them again to the required levels;
- Ride again, but at a speed of 30 km/h, and only 5-6 kilometers;
- Completely disconnect the battery by removing the terminals for 10 minutes, this will help restart the computer;
What actions are required if the tire pressure sensor lights up?
Don’t panic if the alarm goes off and the tire compression light on your Toyota RAV 4 comes on:
- An erroneous operation is possible, it’s worth checking everything carefully;
- If, during the check, you find that the parameters in the wheels do not correspond to the norm, you need to bring them to the norm and eliminate the cause (for example, a nail in the wheel - replace the wheel);
- If, with normal compression in all wheels, the light does not want to go out - only professionals can help here, contact a service station;
- When the lamp blinked for a minute and began to light constantly, this is a sign of a system breakdown; this is definitely a repair at a service station;
How to register new wheel sensors for Rav 4
When installing new devices, it is necessary to register their identification codes in the on-board computer and carry out initialization. To register codes, you need to contact an authorized dealer or a reliable auto repair shop.
The procedure can be carried out independently. You will also need it when installing new tire sizes. With the ignition on, you need to hold the “SET” button located under the steering wheel until the lamp flashes three times.
How much do tire sensors cost on a Toyota RAV4?
The cost of sensors for the RAV 4 varies greatly, depending on the region and brand:
- For example, original Toyotas cost from 2 to 5 thousand rubles each, that is, 8-20 thousand per set;
- Universal, suitable for almost any car - from 10 thousand rubles per set;
If we take leading brands, then the approximate price is:
- General Motors – 2400–3600 rubles
- Mobiletron – 1200-2000 rubles
