• Check the resistance of the CKP sensor, component side.
TERMINAL NO. RESISTANCE (25°C)
1 & 2 Approximately 860
Is the check result normal?
Ye s>>Replace the CKP sensor with a known good CKP sensor.
Monitor the CKP sensor signal on the KES-200 screen.
If the CKP sensor signals were normal, the system is OK.
If the CKP sensor signals were still irregular or missing, go to step 15.
No
>>Replace the CKP sensor.
14.CHECK CAMSHAFT AND CAMSHAFT SIGNAL PLATE
• Remove the cylinder head cover and timing belt cover (See timing belt removal and installation in Section 02
engine).
• Check the installed clearance (See CMP sensor Removal & Installation in Section 03 Electronic Engine Con-
trols).
• 0.8 - 1.2 mm should exist.
• Check the camshaft and camshaft signal plate for any condition that would result in an incorrect signal, such as
damage, become flexible, foreign material when rotate the camshaft.
Were any problems found?
Ye s>>Remove debris and clean the signal plate of camshaft rear end or replace camshaft.
Reinstall CMP sensor.
No
>>Go to step 17.
15.CHECK THE CRANKSHAFT AND CRANKSHAFT SIGNAL PLATE
• Check the installed clearance (See CKP sensor Removal & Installation in Section 08 Transaxle & Transfer
Case).
• 0.8 - 1.2 mm should exist.
• Check the crankshaft and camshaft signal plate for any condition that would result in an incorrect signal, such
as damage, become flexible, foreign material when rotate the camshaft.
Were any problems found?
Ye s>>Remove debris and clean the signal plate of crankshaft rear end or replace crankshaft.
Reinstall the CKP sensor.
No
>>Go to the next step.

• Check for timing misalignment.
Is the timing misaligned?
Ye s>>Align the engine timing belt (See Timing Belt Removal & Installation in Section 02 Engine).
No
>>Go to the next step.
17.CHECK DTC
• With the X-431 scan tool, read ECM DTCs.
• Refer to DTC Confirmation Procedure.
Is DTC P0016 still present?
Ye s>>Replace the ECM.
NOTE : The Immobilizer control module must be matched to the new ECM (See ECM Removal & Instal-
lation in Section 03 Electronic Engine Controls).
No

Description
The Crankshaft Position (CKP) sensor is located on the flywheel shell facing the gear teeth of the signal plate. It
detects the fluctuation of the engine revolution. The sensor consists of a permanent magnet and Induction coil.
Operation
When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The
changing gap cause the magnetic field near the sensor to change. Due to the changing magnetic field, the voltage
from the sensor changes. The Engine Control Module (ECM) receives the voltage signal and detects the fluctuation
of the engine revolution.
Removal & Installation
1. Disconnect the negative battery cable.
2. Disconnect the crankshaft position sensor electricalconnector from the crankshaft position sensor.
3. Remove the accessory drive belt (See Accessory Drive Belt Removal & Installation in Section 02
Engine).
4. Remove the crankshaft pulley (See Crankshaft Pul- ley Removal & Installation in Section 02 Engine).
5. Remove the timing belt lower cover (See Timing Belt Lower Cover Removal & Installation in Section
02 Engine).
6. Remove the crankshaft position sensor retaining bolts (1).
(Tighten: Crankshaft position sensor retaining bolt
to 20 N·m)
7. Installation is in the order of removal.

• Check the operation of the brakes.
Is a fault indicated?
Ye s>>Repair as necessary.
No
>>Go to the next step.
10.ADDITIONAL CHECKS
• Check the following for possible additional causes:
Customer driving habits (such as excessive loads or over RPM limiting functions enabled).
Clutch.
Charging system.
Ignition base timing (if not previously checked).
• If the base timing is not correct, align the engine timing belt (See Engine Timing Belt Removal & Installation in
02 Engine).
Are all checks OK?
Ye s>>See Diagnostic Help for additional information.
No
>>Repair as necessary.
Verify the symptom no longer exists.

7.CHECK FUEL SYSTEM PRESSURE
• Release the fuel system pressure (See Fuel Pressure Relief Procedure in Section 04 Fuel Delivery).
• Check fuel system pressure (See Fuel Pressure Test in Section 04 Fuel Delivery).
Is fuel pressure correct?
Ye s>>Go to the next step.
No
>>If the fuel pressure is greater than 400 kPa (4.0 bar):
Replace the fuel pressure regulator.
If the fuel pressure is less than 400 kPa (4.0 bar):
Check the fuel supply system for restrictions or leaks.
If no problems, repair or replace fuel filter, pressure regulator or fuel pump assembly.
8.CHECK FOR BASE ENGINE CONCERNS
• Check for base engine concerns (such as improper cylinder compression, worn camshaft/valve train, gasket
leaks).
Is a fault indicated?
Ye s>>Repair as necessary.
No

Description
The generator is belt-driven by the engine. It is serviced only as a complete assembly. If the generator fails for any
reason, the entire assembly must be replaced. The generator produces DC voltage.
Operation
As the energized rotor begins to rotate within the generator, the spinning magnetic field induces a current into the
windings of the stator coil.
The Y-type stator winding connections deliver the induced AC current to 3 positive and 3 negative diodes for recti-
fication. From the diodes, rectified DC current is delivered to the vehicle’s electrical system through the generator,
battery, and ground terminals. 1.6L & 1.8L & 2.0L
