The other day we had "engine system service required. I check faults and none, but I erased anyway. Everything runs good. Now tonight coming home the check engine light came on. I checked faults and got a P1152, I think this is a O2 sensor, which one????? Also my temp. gauge is straight up and down, but it seems alfully hot. How can I check to see if fan works properly????

 

p1152 is the front (ie pre-cat) O2. Not sure what bank this is however. If your car isnt a T6 then this doesnt matter. The code literally means signal too high. Could be the the sensor has failed and is pegged at a higher voltage, a short circuit or something emissions related is actually causing it to give that error (less likely if you dont have any other codes)
