It looks like some diagnostics are required, I use a reader that runs as an app on a andriod phone and you can read all sensors,The T16 is much the same except the water pump is driven by an auxillary belt unlike the M16 where it is driven by the cam belt

This is the diagnostic tool i use https://www.the-t-bar.com/forum/9-mgf-tf-pitstop/95085-memsdiag-mems-1-9-ecu-diagnostic-tool
