Ok, I recently replaced my radiator, SERVICE ENGINE LIGHT on, has not gone off even when I reset batt. I am pretty sure the Engine Coolant Temp Sensor is the cause and have heard this is a somewhat reputable to go out, which many will take their car to the shop and waste money on. The chance of spilling antifreeze or even the radiator heating up for long duriations can cause this right? Im pretty damn sure its not the o2 sensors though, if it is maybe the downpipe o2 sensor wire touching the header would cause current to cease in o2 sensor.....

UPDATE:
Totally incorrect assumption or was it??? I went to the shop and actually got a code 0113 from obd2 on my 97 sc2. This is "Intake Air Temp Circuit High Input" in the computer, now is this the o2 sensor or is it something leading to the o2 sensor like a computer or engine coolant temp sensor? I figure it may be the sensor holder (cable attached to fitting which the intake o2 sensor is plugged into) but I need some input asap-thanks

This is NOT related to the o2 sensor.

The intake air temperature sensor (IATS) is IN your intake tubings.

Look and you'll find it. Does any of your friend drive a saturn? If so, borrow their IATS just to see if the SES light come up. If it doesn't, your IATS need to be replaced.

Check ALL your fuses too.

Amazinghl is right, the P0113 is "Intake Air Temperature (IAT) Sensor Circuit High Voltage" and probably means that the IAT sensor is bad. This will probably result in performance loss since the PCM will compensate by dropping into a limp mode for the air/fuel mix. The IAT is a cheap sensor and you're probably safe just buying a new one.
