I need a exploded view of engine intake and vacuume hoses it has emissions control and ac please i need a picture diagram not the one on the fan cover

It will be an intake manifold vacuum tap. Check all the taps from the intake manifold. The fpr hose may be teed off from another hose to another device. Just trace them all down, and you should find it. There would be a vacuum diagram scheme on the emissions label under the hood- see if it is still legible.

Not sure of your engien size as you didn't say so I went with the most common enegine the 3.8 liter. Again I wasn't sure of what vacuum diagram you needed as the is vacuum for emissions, air conditioning and cruise control. the picture above is for emissions for the 3.8 liter engine. Hope this was what you were needing but if you have a different engine (305 or the 3.8 turbo) you can reply back here with what diagram you needed or the correct engine. Hope this helps...

Hope helps.

code p 0441 refers to evaporative emission (EVAP) system --incorrect flow detected ==== causes --- hose connection/s--- intake leak---EVAP canister purge valve replace the purge valve

Hello redeemer524,

Below is the diagram. I hope this helps.

REMOVAL & INSTALLATION

PFE/DPFE Sensor
This component is found on all engines, and is also referred to as the backpressure transducer.

1. Disconnect the negative battery cable.
2. Detach and label the wiring harness connector from the PFE/DPFE sensor.
3. Disconnect all of the hoses from the sensor.
4. Remove the mounting nuts, then separate the sensor from the mounting bracket.
5. If necessary, remove the EVR solenoid and the PFE/DPFE mounting bracket from the upper intake manifold.

To install:

1. If removed, install the EVR solenoid and mounting bracket onto the upper intake manifold.
2. If applicable, install the EGR tube heat shield.
3. Position the PFE/DPFE sensor on the mounting bracket, then install and tighten the mounting nuts until snug.
4. Attach all necessary hoses and wiring to the sensor.
5. Connect the negative battery cable.

EGR Vacuum Regulator (EVR) Solenoid
The EVR solenoid is mounted either on the same bracket as the PFE/DPFE sensor, attached to the upper intake manifold, or near the EGR valve on its own bracket.

1. Disconnect the negative battery cable.
2. Label and detach the wiring harness connector from the EVR solenoid.
3. Detach the main emission vacuum control connector from the solenoid.
4. Remove the retaining nuts, then separate the solenoid from the mounting bracket.

To install:

1. Position the solenoid on its mounting bracket and install the retaining nuts.
2. Attach the main emission vacuum control connector and the wiring harness connector to the EVR solenoid.
3. Connect the negative battery cable.

EGR Valve
See Figures 6 and 7

1. Disconnect the negative battery cable.
2. If necessary, remove the air inlet tube from the throttle body and air cleaner housing.
3. Label and detach all vacuum hoses from the EGR valve.
4. Label and detach any electrical wiring harness connectors from the EGR valve.
5. Disconnect the EGR valve-to-exhaust manifold tube from the EGR valve.
6. Remove the EGR valve mounting fasteners, then separate the valve from the upper intake manifold.
7. Remove and discard the old EGR valve gasket, and clean the gasket mating surfaces on the valve and the intake manifold.
   

Fig. 6: Cutaway view of a base entry type EGR valve

Fig. 7: Cutaway view of a side entry type EGR valve

To install:

1. Install the EGR valve, along with a new gasket, on the upper intake manifold, then install and tighten the mounting bolts to 4-22 ft. lbs. (20-30 Nm) on 3.8L engines, or to 106-49 inch lbs. (1-18 Nm) on 5.0L engines.
2. Connect the EGR valve-to-exhaust manifold tube to the valve, then tighten the tube nut to 30 ft. lbs. (41 Nm).
3. Connect all wiring or hoses to the EGR valve.
4. Install the air inlet tube.
5. Connect the negative battery cable.

Hope this helps, good luck (remember to rate this comments).

here are complete instructions from autozone.com. It doesn't show the clearance, but it does tell you what has to come off to clear.

1. Disconnect the negative battery cable.
   
2. Drain the engine oil.
3. Drain the cooling system.
4. Recover the A/C refrigerant.
5. On the 3.0L (VIN S) engine, remove or disconnect the following:
   
   Windshield wipers Cowl extension Emission vacuum control connector at the right side of the dash panel Hood Steering column pinch bolt Mass Airflow (MAF) sensor connector Intake Air Temperature (IAT) sensor Air cleaner assembly Idle Air Control (IAC) valve connector Throttle Position (TP) sensor connector Fuel lines Intake manifold vacuum hoses Ground straps Powertrain Control Module (PCM) connector Engine control sensor wiring harness connectors from the bracket located at the top of the transaxle Evaporative emission canister purge valve connector Crankcase vent hose Accelerator cable Cruise control actuator Shift cable and lever Secondary air injection pump relay connector Main emission vacuum control connector near the fan shroud Radiator hoses Heater hoses Transaxle oil cooler lines Power steering return hose Alternator wiring harness connectors A/C compressor lines A/C pressure cutoff switch, if equipped Front wheels Stabilizer bar links Lower ball joints Outer tie rod ends Halfshafts Radiator splash shield Heated Oxygen (HO 2 S) sensors Dual converter Y-pipe Power steering pressure switch connector Power steering pressure hose
   
6. Support the powertrain from below and remove the subframe bolts.

Fig. Throttle Position (TP) sensor and Intake Air Control (IAC) valve connectors-2001-04 3.0L (VIN U) engine shown

Fig. Support the powertrain when removing the subframe bolts

1. Raise the vehicle away from the powertrain.
2. Attach an engine hoist to the powertrain.
3. Remove the left, right, and rear powertrain support insulators and lift the powertrain away from the subframe.
4. Support the transaxle from below.
5. Remove or disconnect the following:
   
   Starter motor Torque converter Transaxle flange bolts
   Separate the engine from the transaxle.

Hi, i have posted a link to the diagram(exploded) below.


INTAKE DIAGRAM(EXPLODED)


Please rate and have a great day:)

Exhaust Gas Recirculation (EGR) System The exhaust gas recirculation (EGR) system recirculates exhaust gas into the intake manifold (9424). This lowers combustion temperatures and reduces the formation of oxides of nitrogen (NOX). The amount of exhaust gas reintroduced and the timing of the cycle varies by calibration. Timing and volume are controlled by the powertrain control module (PCM) (12A650). The EGR valve (EGR valve) (9D475) is vacuum actuated. The vacuum hose routing diagram is shown on the Vehicle Emission Control Information (VECI) decal. EGR operation stops when the engine temperature is cold, to improve driveability. The PCM controls the EGR solenoid vacuum valve (9D474). When energized the intake manifold vacuum outlet fitting and cap (9A474) allows exhaust gas to be circulated in the engine to be burned.
