6E1-38 ELECTRONIC FUEL INJECTION SYSTEM (G13/G16 ENGINE WITHOUT WU TWC)
CODE NO.42 CKP SENSOR CIRCUIT
(SENSOR SIGNAL NOT INPUTTED FOR 2 SECONDS AT ENGINE CRANKING)
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 through CKP sensor is in good condition.
When starter motor fails to run and this DTC appears, check starter circuit first.
STEP
1) Disconnect CKP sensor coupler 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.
1
CKP sensor resistance:
360 – 460 W at 20_C (68_F)
4) Measure resistance between each terminal
and ground.
Insulation resistance: 1 MW or more.
Were measured resistance values in Step 3) and
4) as specified?
Check visually CKP sensor and pulley for the
following.
D Damage
D No foreign material attached
2
D Correct installation
Are they in good condition?
Fig. for STEP 1
NOTE:
Upon completion of inspection and repair work, perform final check, referring to "FINAL CHECK" in this
section to confirm that the trouble has been corrected.
ACTION
Fig. for STEP 2
:: With immobilizer control system
YES
Go to Step 2.
"W" or "B" wire open or shorted to
ground, or poor connection at C10
(or C11) or C21 (or C22). If wire and
connection are OK, intermittent
trouble or faulty ECM (PCM).
Recheck referring to "INTERMIT-
TENT AND POOR CONNECTION" in
Section 0A.
1. ECM (PCM)
2. CKP sensor
3. Rotor
NO
Replace CKP
sensor.
Clean, repair
or replace.
