When the tyre pressure monitoring system (TPMS) light on the dashboard illuminates, it typically means that the air pressure in one or more of your tyres has gone below the recommended level.
Additionally, the light may be actuated wrongly by a malfunctioning sensor and may flash arbitrarily, ostensibly due to a sensor issue. However, in some instances, resetting the tyre pressure system may work.
These sensors became popular in the 1990s and later included several vehicles, including the first generation of the Chevrolet Silverado.
In contrast, this sensor effectively prevents damage caused by overinflated or underinflated tyres. But it can eventually wear out or become faulty, resulting in the light remaining on.
What Is the Meaning of a Flashing Tire Pressure Light?
Batteries frequently power tire pressure sensors, and a flashing tyre pressure light indicates that the battery needs replacement. It could potentially be the result of a sensor malfunction.
Suppose you observe a flashing Tire Pressure indicator. In that case, you should schedule an appointment at a repair center so the mechanic can correctly diagnose the issue and get you back on the roads of Decatur safely.
How Does Tire Sensor Work?
The tyre sensor in your car that activates the tyre pressure indicator may be different from the one in your neighbour’s vehicle. Today, two primary systems are in use: direct TPMS and indirect TPMS.
It uses a tyre sensor to read your tyres’ pressures directly. When it detects that your tire(s) has lost 25% or more of its air pressure, it sends a message to the vehicle’s computer, activating the TPMS light on the dashboard.
It is a little more complicated. Rather than measuring the pressure with a tyre sensor, it examines something influenced by the pressure in your tyres. The antilock braking system (ABS) in your vehicle can detect the speed at which your tyres spin. When a tire’s pressure is low, it rolls at a slower pace, alerting the vehicle’s computer.
How Much Air Pressure Should You Put in Your Tires?
Tire pressure expresses in pounds per square inch, or “PSI” – a unit of force that indicates the amount of force present in a particular area.
However, what is the proper tyre pressure? Tire pressures should manage between 30-35 PSI for most automobiles. Nonetheless, the optimal pressure for your car will vary depending on the type of tyres you use and the type of vehicle you ride.
To compensate for larger wheels and lower-profile tyres, cars with big wheels and lower-profile tyres frequently require a higher recommended tyre pressure.
Typically, when off-roading, you must deflate your tyres; therefore, the tyre’s pressure needed changes according to the driving activity.
How to Reset the Tire Pressure Monitoring System Light on 2008 Chevrolet Silverado?
If you replaced a wheel, tyre, TPMS sensor, or another vehicle component and now have a warning light on your dashboard, you must reset the sensor.
To reset your Chevrolet’s Tire Pressure Monitoring System (TPMS) sensor, you’ll need a TPMS to relearn the tool and follow these steps:
- Stop the vehicle safely and activate the parking brake before turning off the engine.
- Without starting the engine, flip the ignition to the ON position.
- Press and hold the lock and unlock buttons on the RKE (Remote Keyless Entry) transmitter to activate the horn.
- Put the relearn tool against the tyre sidewall near the valve stem, beginning with the driver’s side front tyre. Then, activate the TPMS sensor by pressing the button.
- Repair on the right-front tyre, right-rear tyre, and left-rear tyre.
- A horn chirp indicates that the sensor identification code correctly associates this tyre and wheel location.
- Switch off the engine
- Maintain the tyre inflation pressure to the recommended level indicated on the tyre placard on the door panel.
How to Reset Tire Monitor System by Configuring and Replacing TPMS Sensors?
Tires May Require Additional Air
- Tires on your vehicles are constantly in use, and air can escape over time, resulting in tyre deflation.
- If the tyre pressure is less than 25 PSI, the tyre monitor service light will turn immediately.
Configure the TPMS Sensors
When you have done inflating or deflating your tyres (in the case of excessive PSI) or changing a tyre on your vehicle, you should always reset the tyre pressure system.
In some instances, the sensors may be out of sync with one another; in these instances, a method requires resetting the service light.
However, this is an unusual procedure, and it is required to reset the service indicator light.
- Bring your vehicle in the park position.
- Start the vehicle key to the RUN position with the engine turned off.
- It will reset the vehicle and sound the horn twice before the tyre pressure monitor service light continues to flash. Switch the headlight switch from ON to OFF 4 times within three to four seconds to reset the vehicle.
- Remove all air from the vehicle’s front tyre on the driver’s side.
- For ten seconds, deflate the tyre, and the vehicle horn will sound. Reinflate the tyre once the horn stops blaring. The system could have reset, in which case you must repeat the procedure. Each beep signifies that the tyre sensor successfully connects to the monitoring system.
- Repeat the procedure for each tyre.
- When the final tyre inflates, the horn will beep twice to indicate that the procedure completes.
- It is now necessary to switch off the vehicle.
- Fill each tyre to the proper pressure levels using the air compressor.
- Restart the vehicle and verify that the TPMS light illuminates.
Replace the TPMS Sensors
Tire Pressure Monitoring System is a computerised tyre inflation valve that monitors and transmits the air pressure in each tyre to the vehicle’s computer. When the inflation pressure in a tyre falls below the level specified by the sensor, a warning light illuminates to tell the driver that the tyre or tyres underinflate.
It is vital to consider removing and reinstalling the sensors when changing tyres. In some circumstances, typical corrosion may cause harm to the sensors, but an unethical tyre technician may also cause damage if they do not remove properly.
- Pull the valve core carefully from the TPMS sensor. Allow for deflation of the valve.
- Using a wrench and socket, pry away and discard the TPMS sensor grommet. A washer may be included beneath the grommet to prevent leakage in rare instances.
- You should lower the tyre pressure monitoring system (TPMS) sensor valve into the tyre rim. By locking the bead onto the tyre changer, as usual, the sensor will autonomously slide toward the tire’s bottom and into the groove.
- Repeat this technique on both rim edges using a standard tyre changer.
- Secure the tyre on the tyre changer table with flexible clamps to protect it from slipping.
- Separate the tire from the rim by lowering the tire’s top bead. By accessing the TPMS sensor from the outside, you can remove it inside the tyre. If replacing the wheel, you may detach the lower beads from the rim, but if not, you must return the top dot with the lower bead.
- To successfully install the new TPMS sensor, it is necessary to insert the rubber gasket (included in the kit) on the sensor valve.
- Position the tyre sidewall at the front of the valve holes in the rim and press the sensor valve down and then up into the hole. With one hand, secure the washer (if present) and a grommet in place with the other.
- To determine the necessary pounds per inch for tightening the TPMS sensor grommet, consult the TPMS documentation for the relevant vehicle model. Tight the grommet according to the manufacturer’s recommendations after setting the torque wrench to the right setting.
- Inflate the tyre to the optimal pressure as usual.
