please am using a honda 2003 eod model and my temperature always rises almost to the highest level within 1min once i start driving. what should i look out as my mechanic said my temperature sensor is ok.

If the sensor is OK, then the problem is that the engine is overheating.
There are many things that could cause the engine to overheats, leaking coolant, bad water pump, clogged radiator, blown head gasket, etc.
You should start by performing a coolant system service (Drain and refill coolant system)
