Good Day All:
I have a GMC Yukon XL 2002 5.3 V8
The check engine light is on and the codes are P0332 Knock Sensor Circuit Low Frequency Bank 2
The other codes are P0171 and P0174 both are referring to fuel trim system lean bank 1 and 2.
First question: Could these error codes be related?
Second P0332 knock sensor: to remove the air intake manifold the gasket should/will also need to be replaced correct.
Third Question Fuel Trim System Lean: What does that mean and where does that direct me for repairs.
Thank you
Mike
