Technican: You will need to work your way throuhg each code individually.
Code 332. EGR did not open/respond during test. Most common causes. #1 Bad DPFE sensor. #2 Broken vacuum hose to EGR valve #3 Bad EGR valve or solenoid.
Code 118. ECT sensor is/was high or open - Look for a disconnected coolant temp sensor, or borken wire, or bad sensor.
Code 564. Fan Control (FC) circuit failure. Look for bad/missing relay, blown fuse, wiring problem.
Code 556. Fuel pump relay control. I have seen the code often, never fixed it, never had it make a problem. .?.?.
Code 172. Right side oxygen sensor not switching - system is or was lean - Fuel control This could be the most difficult to figure out. It could be a vacuum leak, a bad oxygen sensor, clogged injectors, misfiring plugs.... Fix the others first, clear the codes and see if this one comes back, or stays away.
