5-6
Secondary Winding
1. Remove the plug cap from the high tension lead;
then connect the red tester lead to the high tension
lead.
2. Connect the black tester lead to either primary
connector.
3. The meter reading must be within specification.
NOTE: If the meter does not show as specified,
replace ignition coil.
Spark Plug Cap
1. Connect the red tester lead to one end of the cap;
then connect the black tester lead to the other end
of the cap.
AR603D
2. The meter reading must be within specification.
NOTE: If the meter does not read as specified,
replace the spark plug cap.
PRIMARY VOLTAGE - ECU
NOTE: The battery must be at full charge for this
test.
NOTE: The ECU is located beneath the rear
fender near the taillight.
1. Set the meter selector to the DC Voltage position;
then disconnect the orange primary wire from the
coil.
2. Connect the red tester lead to the primary wire;
then connect the black tester lead to ground.
3. Turn the ignition switch to the ON position.
4. The meter reading must be within specification.
EFI Sensors/
Components
CRANKSHAFT POSITION (CKP)
SENSOR
To test the CKP sensor, see Stator Coil/Crankshaft
Position (CKP) Sensor in this section.
MANIFOLD ABSOLUTE PRESSURE
(MAP) SENSOR
1. Disconnect the MAP connector from the pressure
sensor located on top of the throttle body.
2. Select DC Voltage on the tester and turn the igni-
tion switch to the ON position.
3. Connect the black tester lead to the black/green
wire and the red tester lead to the orange/blue
wire. The meter should read 4.5-5.5 DC volts. If
the meter does not read as specified, check the
ECU connector or wiring.
4. Connect the MAP to the harness; then using Maxi-
Clips, connect the red tester lead to the
brown/white wire and the black tester lead to the
black/green wire. With the engine running at idle
speed, the meter should read approximately 1.5
DC volts.
NOTE: If the meter does not read as specified,
replace the sensor.
Speed Sensor
NOTE: Prior to testing the speed sensor, inspect
the three-wire connector on the speed sensor for
contamination, broken pins, and/or corrosion.
1. Set the meter selector to the DC Voltage position.
2. With appropriate needle adapters on the meter
leads, connect the red tester lead to the voltage
lead (V); then connect the black tester lead to the
ground lead (G).
