How does a direct TPMS system work on a car?

Direct TPMS systems use TPMS sensors inside the wheel to accurately report pressure data to the vehicle’s ECU in real time. Direct systems include Asian, domestic and European vehicles. An indirect TPMS system uses an ABS system to monitor the speed of the wheel in order to approximate tire pressure.

What are the different types of TPMS sensors?

There are 2 main types of TPMS: Direct and Indirect. The direct TPMS has sensors located on the tire’s pressure valve or the rim. These sensors collect information and send it to the car’s on-board computer. However, the direct TPMS is most likely to malfunction due to bad weather conditions. It is usually found in cars in the United States.

Where is the reset button on a TPMS car?

Most of the cars with direct TPMS have a reset button located under the steering wheel through which you can conveniently re-calibrate the sensors.

What does it mean when your TPMS warning light is on?

So check your tires carefully. If your vehicle has a TPMS, it’s probably monitoring the pressure in your spare tire. Therefore, if you get a low tire pressure warning light, and if you’ve checked all four tires that are touching the ground, than you might need to put some air in the spare.

How does the TPMS light work on an Acura?

An indirect TPMS employs speed sensors from the anti-lock braking (ABS) system to measure the rotational speed of each tire. If a tire rotates faster than the others, it determines that this tire has lost pressure and illuminates the TPMS light. The threshold is 25% of Acura’s recommended tire pressure.

How do you check the TPMS system on a car?

It is important check the TPMS system before working on a customer’s vehicle. Using a TPMS diagnostic tool, select the vehicle’s make, model and year manually – or for faster service, scan the vehicle’s VIN barcode located on the placard on the vehicle doorjamb to read the sensor information.

If your car’s main battery has drained recently, it may well have depleted the airbag backup battery too.

What makes the SRS airbag warning light work?

An airbag system consists of a few sensors, a module that interprets the signal, and an airbag that contains a small charge that allows it to deploy during an accident. These sensors can become worn and torn after time, most commonly in the passenger-side occupancy sensor and the clock spring.

How to reset a stuck low pressure ( TPMS ) light?

Put the key in the ignition and turn it to the “on” position, but do not start the car. Press and hold down the reset button (sometimes located under the steering wheel) until the low-pressure light blinks three times. Release the button. Start the vehicle and let it run for 20 minutes to let its computer re-calibrate each sensor.

How long does it take for a TPMS light to blink?

If a malfunction occurs (typically a sensor issue), the MIL will blink for 60 to 90 seconds and then go solid. The first step in properly diagnosing a TPMS issue is to note what the TPMS light/MIL tells you at start-up.

When to notify the driver of a TPMS fault?

Many vehicles do not immediately warn the driver of a failed sensor or failed battery. There is no provision for this in TPMS legislation. The TPMS must notify of a low pressure condition immediately. However, the rules on declaring a system fault warning are less rigid.

What to do if your TPMS warning light is still on?

How does TPMS know which tire is in which location?

There are two tire pressure monitoring systems available, a base system and a premium system. The base system does not specify how many tires are low or where they are located. The premium system does so. Both TPM systems consist of tire pressure monitoring sensors attached to each road wheel through the valve stem mounting hole and a TPM module.

How does a tire pressure sensor work on a jeep?

Both TPM systems consist of tire pressure monitoring sensors attached to each road wheel through the valve stem mounting hole and a TPM module. The TPM module (1) is fixed to a metal bracket (3) mounted onto the rear crossmember frame. The TPM module decodes the RF signals transmitted by each of the vehicle’s tire pressure sensors.
