Where is the TPMS ECU located?

The TPMS ECU is typically housed near the braking system, most often integrated with the ABS/ESP module in the engine bay. Exact placement varies by make, model, and year, so consult your vehicle’s manual for a precise location.

In most modern cars, the centralized tire-pressure monitoring computer collects data from each wheel sensor and communicates with the vehicle’s main electronics. Because manufacturers distribute the hardware differently, the TPMS ECU can live in several common spots, sometimes as part of the ABS assembly rather than as a standalone box. This article outlines the typical locations and how to identify the unit on your specific vehicle.

Common TPMS ECU locations

To save time, note that many systems place the TPMS controller near other braking or dash-area electronics. The following locations are the ones most often seen across a wide range of vehicles.

• Engine bay, near the ABS pump and master cylinder (often on the driver’s side firewall or strut tower area).


• Under the driver’s side dash, behind the knee bolster or near the fuse/relay box.


• In the passenger footwell, behind trim near the glove box or kick panel.


• Inside the trunk, adjacent to the spare wheel well or near the taillight control module on some models.


• Integrated with the ABS/ESP control module assembly, rather than a separate standalone unit.

Because many systems consolidate TPMS with the ABS, the ECU is frequently found within or directly next to the ABS assembly. If you’re unsure, refer to the official service documentation for your exact year and trim, or ask a dealer or qualified mechanic.

How to confirm the location for your vehicle

Use these steps to pinpoint the TPMS ECU for your specific car without guessing.

• Check the owner’s manual or the official service/repair manual for your exact model and year—look for the TPMS or ECU location section.


• Use a TPMS diagnostic tool or professional scan tool to identify which module handles TPMS data; the tool can sometimes point you to the physical location based on VIN.


• Inspect common mounting points first: ABS/ESP modules in the engine bay, the knee-panel area under the driver’s dash, the glove box region, and the trunk near the wheel well.


• Be cautious with airbags and related systems; if you’re unsure, have a professional technician locate or service the TPMS ECU.

Understanding that the TPMS ECU’s location is model-dependent will save time and reduce the risk of damage when inspecting or servicing the system.

Manufacturer-specific tendencies

Some brands tend to place the TPMS controller directly within the ABS module in the engine bay, while others route it to the dash area or the glove box. European marques often integrate TPMS control with centralized body ECU or ABS modules, whereas many Asian and American models place the unit near the ABS pump or under the driver’s dash. Always verify with model-specific documentation.

Summary

In short, the TPMS ECU is not universally fixed in one location. It is usually located near the ABS/ESP system in the engine bay, but can also reside under the dash, in the trunk, or as part of the ABS assembly depending on the vehicle. To locate it accurately, consult the exact service manual for your car, or use a TPMS tool to help identify the relevant control unit. When in doubt, seek professional assistance to avoid misidentifying components.

Where is the TPMS module located?

The TPMS (Tire Pressure Monitoring System) control module is most often located in the rear of the vehicle, behind a wheel well or under the rear seats, while the sensors are inside each wheel. Other locations can include the front of the vehicle, under a seat, or integrated with other modules. The specific location depends on the vehicle make and model, so consult your owner's manual or a vehicle-specific diagram.

Control module location

• Common locations:
  • Behind the rear wheel wells
  • Under the rear seats, often under the carpet
  • Attached to the rear subframe
  • Near the dashboard or trunk
  • In the front splash guard area
• Varying locations: The module may be mounted near the front of the vehicle or integrated with other electrical components like the remote control door lock receiver. 

Sensor location

• Direct sensors:
  • Attached to the valve stem on the inside of the wheel
  • Strapped to the barrel of the wheel
• Indirect sensors:
  • These systems use the existing ABS speed sensors in the wheels. 

Tips for finding the module

• Consult your owner's manual, a service manual, or look up your specific vehicle's model and year online for exact placement. 
• For some vehicles, a diagram of the module's location is available on forums or service sites.

How to delete TPMS from ECU?

Remove the wheel sensors and disable the TPMS in the CCF, Menu–Car Config–Body Control. You can also leave the sensors and disconnect the fuse. This will however disable both the TPMS and parking aid (PAM) ECUs.

Is disabling TPMS illegal?

Yes, in the U.S., it is illegal for a repair shop to disable a functional Tire Pressure Monitoring System (TPMS) because it's mandated for all new vehicles sold since 2008. While it is not explicitly illegal for an owner to disable it in all states, doing so can lead to issues with vehicle inspections and resale, and it removes a safety feature designed to alert you to low tire pressure. 
Legality

• Manufacturers and repair shops: It is illegal for manufacturers, distributors, dealers, and repair businesses to knowingly make a functioning TPMS inoperative, due to a provision in the Motor Vehicle Safety Act. 
• Vehicle owners: While some sources say it's not illegal for an owner to disable the system in certain states, the lack of a functional TPMS could cause a vehicle to fail inspections, especially since the law requires all new vehicles to have one. 

Risks of disabling TPMS

• Safety hazard: The primary purpose of TPMS is to alert you to low tire pressure, which can lead to accidents if not addressed. 
• Vehicle inspection failure: Disabling the system may cause a vehicle to fail state inspections. 
• Reduced resale value: Potential buyers may be concerned about the safety and maintenance implications of a disabled TPMS, which can lower your vehicle's resale value. 
• Voided warranty: Disabling the system could void your vehicle's warranty. 

What is a TPMS ECU?

Direct TPMS readings are provided by pressure sensors mounted inside of each tire that send pressure readings to the vehicle's central computer (ECU) which are later displayed on the dashboard. A warning indicator light on the instrument panel and an audible warning notify the driver if a 20% drop in pressure occurs.
