Chrysler Repair: EGR Valve,, negative battery cable, inlet air temperature sensor

Question
Am trying to take the bottom of the air box off to be able to get to the EGR valve on our 2001 PT cruiser basic. Looks to be several clips that will release it but the screwdriver does not release the air box. My record with plastic clips is not pretty. The engine code is p0401 low flow EGR valve.                Thanks

Answer
EGR VALVE AND TRANSDUCER - 2.4L
If the EGR system operates incorrectly, replace the entire EGR valve and transducer together. The EGR valve and electrical transducer are calibrated together.

Remove the air cleaner lid, disconnect the inlet air temperature sensor and makeup air hose.
Remove the negative battery cable.
Loosen the bolts at the intake manifold EGR Tube at Intake Manifold
Remove EGR tube bolts at EGR Valve.
Unclip EGR transducer bracket EGR Transducer Bracket , EGR Transducer Bracket and remove from bracket.
Disconnect the vacuum supply hose to EGR transducer solenoid Vacuum Hose
Unlock the connector then disconnect the electrical connector from solenoid Electrical Connector
Remove the 2 bolt at EGR valve to cylinder head. Remove EGR valve and transducer.
Clean gasket surfaces. Discard old gaskets. If necessary, clean EGR passages.
INSTALLATION
Connect vacuum supply tube to solenoid Vacuum Hose
Attach electrical connector to solenoid Electrical Connector
Install EGR transducer into the bracket and snap closed EGR Transducer Bracket
Loosely install EGR valve with new gaskets.
Finger tighten EGR tube fasteners.
Tighten EGR valve mounting screws to 22 N·m (195 in. lbs.) torque.
Tighten EGR tube fasteners to 11 N·m (97 in. lbs.) torque
NOTE: Make sure that the hoses are routed away from the hot EGR tube and Valve and clipped.

Install the negative battery cable.
Install the air cleaner lid, connect the inlet air temperature sensor and makeup air hose.
