TROUBLESHOOTING (DTC P0335)
STEP ACTION YES NO
1 Was “ENGINE DIAG. FLOW TABLE” performed? Go to Step 2. Go to “ENGINE
DIAG. FLOW
TABLE”.
2 CKP Sensor and Its Circuit Resistance Check:
1) With ignition switch OFF, disconnect ECM (PCM)
coupler (C51-2).
2) Check for proper connection to ECM (PCM) at
C51-2-19 and C51-2-20 terminals.
3) If OK, check resistance of followings.
Resistance between C51-2-19 and C51-2-20 terminals:
360 – 460
at 20
_
C, 68
_
F (G16)
484 – 656 at 20
_
C, 68
_
F (J20)
Resistance between each terminal and ground:
1M
or more
Is check result satisfactory?
Go to Step 4. Go to Step 3.
3 CKP Sensor Resistance Check:
1) With ignition switch OFF, disconnect CKP sensor
coupler.
2) Check resistance between terminals of CKP sensor
coupler for G16 engine, between “2” and “3” terminals
for J20 engine and between each terminal and ground.
(See Fig.)
Were measured resistance values as specified in Step 2?
Faulty “W / Bl” wire
or “Or / Bl” wire. Faulty CKP
sensor.
4 CKP Sensor Visual Inspection:
1) Check visually CKP sensor and signal rotor (crankshaft
timing belt pulley for G16 or CKP sensor plate on
crankshaft for J20) for the followings. (See Fig.)
– Damage
– No foreign material attached
– Correct installation
Are they in good condition?
Intermittent trouble
or faulty ECM
(PCM). Recheck for
intermittent refer-
ring to “Intermittent
and Poor Connec-
tion” in Section 0A. Replace or
reinstall.
