²The PCM grounds the coil side of the relay
through terminal number 85.
²Terminal number 86 supplies voltage to the coil
side of the relay.
²When the PCM de-energizes the ASD and fuel
pump relays, terminal number 87A connects to termi-
nal 30. This is the Off position. In the off position,
voltage is not supplied to the rest of the circuit. Ter-
minal 87A is the center terminal on the relay.²When the PCM energizes the ASD and fuel
pump relays, terminal 87 connects to terminal 30.
This is the On position. Terminal 87 supplies voltage
to the rest of the circuit.
The following procedure applies to the ASD and
fuel pump relays.
(1) Remove relay from connector before testing.
(2) With the relay removed from the vehicle, use
an ohmmeter to check the resistance between termi-
nals 85 and 86. The resistance should be 75 ohms +/-
5 ohms.
(3) Connect the ohmmeter between terminals 30
and 87A. The ohmmeter should show continuity
between terminals 30 and 87A.
(4) Connect the ohmmeter between terminals 87
and 30. The ohmmeter should not show continuity at
this time.
(5) Connect one end of a jumper wire (16 gauge or
smaller) to relay terminal 85. Connect the other end
of the jumper wire to the ground side of a 12 volt
power source.
(6) Connect one end of another jumper wire (16
gauge or smaller) to the power side of the 12 volt
power source.Do not attach the other end of the
jumper wire to the relay at this time.
WARNING: DO NOT ALLOW OHMMETER TO CON-
TACT TERMINALS 85 OR 86 DURING THIS TEST.
DAMAGE TO OHMMETER MAY RESULT.
(7) Attach the other end of the jumper wire to
relay terminal 86. This activates the relay. The ohm-
meter should now show continuity between relay ter-
minals 87 and 30. The ohmmeter should not show
continuity between relay terminals 87A and 30.
(8) Disconnect jumper wires.
(9) Replace the relay if it did not pass the continu-
ity and resistance tests. If the relay passed the tests,
it operates properly. Check the remainder of the ASD
and fuel pump relay circuits. Refer to 8, Wiring Dia-
grams.
REMOVAL
The ASD relay is located in the Power Distribution
Center (PDC) (Fig. 3). Refer to label on PDC cover
for relay location.
(1) Remove PDC cover.
(2) Remove relay from PDC.
(3) Check condition of relay terminals and PDC
connector terminals for damage or corrosion. Repair
if necessary before installing relay.
(4) Check for pin height (pin height should be the
same for all terminals within the PDC connector).
Repair if necessary before installing relay.

for relay location.
(1) Install relay to PDC.
(2) Install cover to PDC.
CAMSHAFT POSITION
SENSOR
DESCRIPTION - DIESEL
The three-wire Camshaft Position Sensor (CMP) is
located below the fuel injection pump (Fig. 4). It is
attached to the back of the timing gear cover hous-
ing.
DESCRIPTION - 3.9L/5.2L/5.9L
The Camshaft Position (CMP) sensor is located in
the distributor.
DESCRIPTION - 8.0L
The Camshaft Position (CMP) sensor is located on
the timing chain case/cover on the left-front side of
the engine (Fig. 5).
OPERATION - DIESEL
The Camshaft Position Sensor (CMP) performs
multiple functions. One function is to detect engine
speed (rpm). Another function is to relate crankshaft
position and Top Dead Center (TDC) of the number 1
cylinder. Because the CMP is now used to relate
crankshaft position,the Crankshaft Position Sen-
sor (CKP) is no longer used.The CMP (Fig. 6) contains a hall effect device
called a sync signal generator to generate a sync sig-
nal.
The CMP uses three wires (circuits) for operation.
One wire supplies a 5±volt signal from the Engine
Control Module (ECM). Another wire supplies a sen-
sor ground. The third wire supplies a signal back to
the ECM relating engine speed and crankshaft posi-
tion.
