Had CEL - ERROR CODE p-0125

[tspinning]

OK did a little digging and get this p-0125 = insufficient coolant temperature for closed loop fuel system

I've read some places (with other cars) this could be coolant temp sensor, 02 sensor, wire issue (on 02 sensor)...

My main question- (the car feels, smells, drives fine) is that i am going on a little road trip tonight, about 200 miles each way, and don't want to ruin my car....

Who would advise against or for my drive??

I spoke w/ my mechanic about this, (stopped by shop to get code from CEL) and he said he can hook her up for a few hours of diagnostics and probably find where the bad sensor or issue is, he didn't seem to think it would harm my car to drive a way as everything is operating normally from sight/sound/feel and the temp gauge has kept itself in a safe area (hasn't changed max temp once warm from date of car purchase 3 weeks ago)

Anyone else had this special code??

Thanks,
Tspin
