Downloaded from www.Manualslib.com manuals search engine Crankshaft Position (CKP) Sensor
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.

The following conditions apply to this symptom:
•Slow return to idle.
1.PRELIMINARY CHECKS
• Carry out the following preliminary checks:
Vacuum leaks
Intake air system
Throttle body
Are all checks OK?
Ye s>>Go to the next step.
No
>>Repair as necessary.
Verify the symptom no longer exists.
2.CHECK ECM DTC
• Turn the ignition switch on.
• With the scan tool X-431, read the DTC.
Are there any DTCs present?
Ye s>>Repair as necessary.
No
>>Go to the next step.
3.CHECK PCV VALVE
• Remove Positive Crankcase Ventilation (PCV) valve and shake it.
Does PCV valve rattle?
Ye s>>Install PCV valve, go to the next step.
No
>>Replace the PCV valve.
4.CHECK PCV SYSTEM
• Start engine and bring to normal operating temperature. Disconnect crankcase ventilation hose from PCV valve.
Place a stiff piece of paper over the hose. Wait 1 minute.
Does vacuum hold paper in place?
Ye s>>Verify test results. If OK, see diagnostic index to repair any additional symptom.
No
>>Check for vacuum leaks, obstructions in the PCV system, oil cap, PCV valve, rocker cover bolt
torque/gasket leak. Repair as necessary.

Description
The electronic ignition system consists of the following components:
•Engine Control Module (ECM)
• Ignition Coil
• Spark Plugs
• Spark Plug Wires
• Camshaft Position (CMP) Sensor
• Crankshaft Position (CKP) Sensor
Operation
The ignition system utilizes a split ignition coil which supplies secondary voltage to two cylinders. When the ignition
coil discharges, two spark plugs fire at the same time. The Engine Control Module (ECM) uses inputs from the
Crankshaft Position (CKP) Sensor to determine the Top Dead Center (TDC) position of the piston for cylinder number
one, and the Camshaft Position (CMP) Sensor to determine which ignition coil to energize.

Ignition Coil 1.6L & 1.8L & 2.0L
Description
The ignition coil consists of primary and secondary groups of wire. The primary wire is located on one end of the coil.
One end of the wire is connected to power and the other end is connected to the Engine Control Module (ECM). The
secondary coil connects two spark plugs. They form a loop and provide high-voltage output.
Operation
When the primary wire is connected to power, current will flow causing a strong magnetic field to form. When the
primary wire is disconnected, the magnetic field will collapse into the secondary wire causing very high voltage out-
put.
Removal & Installation
1. Remove the engine cover.
2. Disconnect the negative battery cable.
3. Disconnect the ignition coil electrical connector.
4. Twist the spark plug wires (1) from the ignition coiland remove the four spark plug wires.
