Just cleared them with the hypershit they were p0161, p0420, p0430. What do these mean?

edit- i ran a search and came up with the 420 one it is a bad o2 sensor, on the pass side


my friends truck pulled a p0332 also, what is that?

 

0161 = HO2S Heater Performance Bank 2 Sensor 2
0420 = Evaporative Emission [EVAP] System Small Leak Detected
0430 = Catalyst System Low Efficiency Bank 2
0332 = Knock Sensor 2 Circuit Low Input (Bank 2)

thanks, what would cause that 0420 = Evaporative Emission [EVAP] System Small Leak Detected???

 

commonly a loose gas cap

 

oh, thanks. I just switched to a locking one cuz ppl have been getting gas siphoned out of their tanks around here and at almost $80 to fill up, i dont need that.

 

The new gas cap may not be sealing properly...
