Where is the air charge temp control sensor located on a 1999 ford explorer 4.0 sohc


Generally the Air charge temp sensor is in the intake tube between the air box & the intake. However, there is a possibility that it is part of the Mass air flow sensor.

I need written instructions for installing an EGR Valve on a 96 Ford Exploer Eddie Bauer V6 4.0 engine. Trying to pass emission inspection.


zjlimited_986.jpg

Fig. 4: Exploded view of the EGR system and related components for the 4.0L engine (click over pic for zoom)

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.
zjlimited_987.jpg

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

zjlimited_988.jpg

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).

I have a 1998 Ford Explorer with a 4.0 engine and a SOHC. I need to replace the thermastat housing. Is there to replace it without having to remove the intake manifold.


Yes. You should be able to replace it without removing the intake manifold. The bolts are very hard to reach, but it can be done with the proper set of sockets and universal joint extensions. I know it looks impossible. If in doubt, take it to a reputable repair shop. Don't let anybody charge you for intake manifold removal.

NO you dont have to take the intake off it should be right on the fuel rail with either 1 or 3 bolts if i remember right it will be the only thing on the rail with a vacuum hose on it.
