Tire Pressure Monitoring Systems (TPMS) have become an essential safety feature in modern vehicles, alerting drivers to low tire pressure and preventing potential hazards.
While TPMS sensors come in two main types: direct and indirect tire pressure sensors, the two have different working, resetting, and relearning procedures.
A car may be equipped with direct or indirect tire pressure sensors. However, the direct TPMS sensors, most common in modern vehicles, have a different resetting procedure. Meanwhile, indirect TPMS sensors can be reset using a magnet too. Let’s find out more details on resetting indirect TPMS sensors. Using a magnet but before that, here are details on indirect TPMS sensors.
What Is An Indirect TPMS Sensor?
Indirect TPMS systems differ from their direct counterparts by utilizing the vehicle’s existing anti-lock braking system (ABS) to monitor wheel rotation and detect changes in tire pressure. By comparing the rotational speeds of the wheels, the system can infer if a tire’s pressure is significantly low.
This indirect approach eliminates the need for individual tire pressure sensors, making it a cost-effective alternative. Speaking of that, let us go through how a magnet can be used to reset the indirect TPMS sensors.
Resetting an indirect TPMS system often involves triggering the ABS module to recalibrate and establish new baseline values for wheel rotation. This is where magnets come into play.
The magnetic field generated by the magnet influences the sensors in the ABS module, prompting the system to update its reference values.
Resetting a TPMS sensor requires expertise. Before attempting to reset an indirect TPMS system with magnets, it is crucial to consult your vehicle’s manual or seek professional advice. The specific procedure may vary depending on the make and model of your vehicle. Here are a few general steps that may be involved:
- Review the TPMS section of your vehicle’s manual for specific instructions regarding the reset procedure.
- Locate the ABS module, which is often found near the brake master cylinder or under the vehicle’s hood.
- Follow the manual’s guidelines and place the magnet near the valve stem or rotate it around the tire in proximity to the ABS module.
- Trigger the reset process by starting the vehicle’s engine and initiate the reset procedure as instructed. This may involve cycling the ignition or pressing a specific sequence of buttons.
- Once the reset process is complete, It’s warning light should turn off, indicating successful recalibration of the tire pressure sensors.
The use of magnets for resetting indirect TPMS systems offers several benefits. It eliminates the need for expensive sensor replacements and minimizes downtime and maintenance costs. Additionally, this procedure can be performed by vehicle owners themselves.
avoiding the need for a visit to the dealership or a mechanic.
However, it is essential to exercise caution when attempting this procedure. Improper magnet placement or incorrect execution may lead to system malfunction or inaccurate readings.
Therefore, it is crucial to follow the vehicle manufacturer’s guidelines. Precisely to ensure a successful reset after your tires lose pressure and you inflate them.
When you have an indirect car TPMS, you must follow the proper guidelines to reset the sensors. Moreover, follow the tips to install the It’s sensor and then calibrate them to function properly.
