Removal & Installation - Ford Ranger Maintaince And Repair Manual

Two Wire Sensors
1. With the ignition OFF, install a break−out box between the CMP sensor and PCM.
2. Using a Digital Volt−Ohmmeter (DVOM) set to the voltage function (scale set to monitor less than 5
volts), measure the voltage between break−out box terminals 24and 46with the engine running at
varying RPM. If the voltage reading varies more than 0.1 volt AC, the sensor is okay.
REMOVAL & INSTALLATION
1995−97 2.3L and 1998−99 2.5L Engines
According to the manufacturer, the A/C system, if equipped, must be discharged for this procedure.
Have your A/C system refrigerant reclaimed by an MVAC certified repair shop. However, there may
be enough flex or slack in the A/C lines to allow you to support the compressor off to the side without
disconnecting the lines.
1. Disconnect the negative battery cable.
2. Remove the accessory drive belt.
3. Remove the four bolts securing the A/C compressor to the mounting bracket and set aside.
4. Remove the three compressor/power steering bracket retaining bolts.
5. Pull the bracket, with the power steering pump attached, away from the engine and position it aside.
6. Disconnect the engine control sensor wiring from the camshaft position sensor.
7. Remove the two CMP mounting bolts and then pull the sensor from the oil pump.
To install:
8. Install the CMP sensor to the oil pump and tighten the two mounting screws to 45−61 inch lbs. (5−7
