TROUBLESHOOTING
Step
1 Was "Engine and Emission Control System
Check" performed?
2 Check CKP sensor and connector for proper
installation.
Is CKP sensor installed properly and connector
connected securely?
3 Check Wire Harness and Connection.
1) Disconnect connector from CKP sensor.
2) Check for proper connection to CKP sensor at
"BLK/RED", "PNK" and "YEL/BLK" wire termi-
nals.
3) If OK, turn ignition switch ON and check for
voltage at "BLK/RED", "PNK" and "YEL/BLK"
wire terminals of disconnected CKP sensor
connector. See Fig. 1.
Terminal "B+": 10 – 14 V
Terminal "Vout": 4 – 5 V
Terminal "GRD": 0 V
Is check result satisfactory?
4 Was terminal "Vout" voltage in Step 3 out of speci-
fication?
5 Check Ground Circuit.
1) Turn ignition switch to OFF position.
2) Measure resistance between "YEL/BLK" wire
terminal of CKP sensor connector and engine
ground.
Is resistance below 5 Ω?
6 Check Engine Start Signal.
1) Check voltage between "C63-35" wire terminal
of ECM connector and engine ground with
engine cranking.
Does it voltage more than 6 V?

poor connection.
If wire and connection are
OK, substitute a known-
good ECM and recheck.

tem Check" in this sec-
tion.
Correct.
Go to Step 4.
"BLK/RED" and "YEL/
BLK" wire open, short
or poor connection.
"YEL/BLK" wire open
or high resistance.
"BLK/YEL" wire circuit
open, high resistance
or shorted to ground.
If wire are OK, check
starting motor referring
to "Starting Motor
Inspection" in Section
6G.
