6-1-74 ENGINE GENERAL INFORMATION AND DIAGNOSIS (SFI FOR G13)
INSPECTION
NOTE:
If starter circuit is open (i.e., start signal circuit is OK but starter fails to run), this DTC is stored in memory
at starter switch ON, even though CKP sensor is in good condition.
When starter motor fails to run and this DTC appears, check starter circuit first.
STEP
1 Was "ENGINE DIAG. FLOW TABLE" performed?
2 Is there DTC P1500 (Engine starter signal circuit)?
3 Check CKP Sensor for Resistance.
1) Disconnect CKP sensor connector with ignition
switch OFF.
2) Then check for proper connection to CKP sensor
at "W" and "B" wire terminals.
3) If OK, measure sensor resistance between
terminals. See Fig. 1.
CKP sensor resistance: 360 – 460 Ω at 20_C,
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?
4 Check visually CKP sensor and pulley for the
following. See Fig. 2.
D Damage
D No foreign material attached.
D Correct installation.
Are they in good condition?
Fig. 1 for Step 3
ACTION
68_F
Fig. 2 for Step 4
YES
Go to Step 2.
Go to DTC P1500
Diag. Flow Table.
Go to Step 4.
"W" or "B" wire open or
shorted to ground, or
poor connection at
C01-23 or C01-24.
If wire and connection
are OK, intermittent
trouble or faulty ECM
(PCM).
Recheck for
intermittent referring
to "Intermittent and
Poor Connection" in
Section 0A.
NO
Go to "ENGINE DIAG.
FLOW TABLE".
Go to Step 3.
Replace CKP sensor.
Clean, repair or
replace.
