| Re: '01 Catera- Check Engine Light - good tech in 60016 They probably erased the code after reading it. Typically the CEL will stay lit for 20 - 30 start/stop cycles unless cleared. Obviously, the CEL will not clear if the trouble persists. My OBD II Code list says:
P0176 Fuel Composition Sensor Circuit Malfunction
As alarms go, this one is kind of minor. Try running a can of fuel treatment like Techron or PRI to a full tank of gas. There may be water or other contaminates in you tank. Maybe the injectors are dirty. Either way, a can of the stuff can't hurt.
