2009 Pontiac G6 Repair Question
Have a 2009 Pontica G6, still a 1000 miles before next oil change, no engine alert lights, however recently have a whine sound everytime I start it..... seems to be coming from TacMeter...... as it gets higher if I raise the engine and is louder the cold
The signal for the Tach is pulled from the Camshaft Position Sensor. The noise you are hearing is probably a bushing that was not pressed in straight and makes more noise in the cold as it contracts. As it heats up it expands and the noise gets quieter.
