INSPECTION
STEP
1 Was "ENGINE DIAG. FLOW TABLE" performed?
2 Check CKP Sensor for Resistance.
1) Disconnect CKP sensor connector with ignition
switch OFF.
2) Then check for proper connection to CKP sensor
at "PNK" and "BLU" wire terminals.
3) If OK, measure sensor resistance between
terminals. See Fig. 1.
CKP sensor resistance: 360 – 460 Ω
4) Measure resistance between each terminal and
ground.
Insulation resistance: 1 MΩ or more.
Were measured resistance valves in step 3) and 4)
as specified?
3 Check visually CKP sensor and pulley for the
following. See Fig. 2.
D Damage
D No foreign material attached.
D Correct installation.

YES
Go to Step 2.
Go to Step 3.
"PNK" or "BLU" wire
open or shorted to
ground, or poor
connection at E23-3
or E23-11.
If wire and connection
are OK, intermittent
trouble or faulty ECM
(PCM).
Recheck for
intermittent referring
to "Intermittent and
