Can you add sensors to any car?

It is technically feasible to install additional sensors on vehicles, but local regulatory requirements must be strictly followed. According to current regulations, installing sensors related to safety performance (such as tyre pressure monitoring or blind spot detection) must ensure compliance with original factory safety standards, and the modified vehicle must pass inspection by a JPJ-recognized testing institution. Notably, if performance sensors (such as turbo pressure gauges) involve power system modifications, prior approval from the Department of Transportation is required, whereas non-contact interior sensors (like temperature and humidity monitors) typically don't need registration. Vehicle owners should select SIRIM-certified accessories and have them installed by professional technicians to ensure electrical safety, avoiding annual inspection failure or insurance voidance due to improper modifications. Before proceeding, consult an authorised modification shop or JPJ office to verify specific project compliance.
