Are electrical o r ECU-related issues in Alsvin in Pakistan responsible for triggering multiple false sensor codes?

Could a deeper issue in the ECU o r wiring harness be causing sensors to malfunction even if they’re physically fine?

Yes, many users have observed:

Loose ECU ground wires causing fluctuating voltage and sensor errors.

Moisture in ECU connector plugs, especially after car wash o r rain.

Some units may have ECU software bugs that misinterpret normal sensor data as fault codes.

In rare cases, ECU flashing o r wiring harness cleanup resolved the issue without replacing sensors.
