Get a real time scan and you will know if the temps are correct. What engine?
There are 3 items which could cause (or cause you to think it has) low engine temperatures.
1) Thermostat stuck on open.
2) Engine Coolant Temperature Sensor broken.
3) Temperature Gauge Sender broken (this should not cause bad engine performance).
