2002 3.4 liter

The problem is my evap system and knock sensors. I replaced the charcoal canister ans knock sensors. The knock sensors came back immediately. Then I replaced the injectors and the mass air flow, Put a new timing belt on and new spark plugs. I'm still getting e-vap and knock sensor codes. I went so far as to buy a $2,500.00 Scanner tool from snap-on tool. The problem still persists. I need some serious input. Thanks.

 

Just remember any code is the complete circuit .

Not just the sensor or part also the wiring and ECM

Might be physical damage to the wiring poor connections.

Did your ECM get wet or get a voltage spike ?? About the only thing that causes damage
