REMOVAL

The Automatic Shutdown (ASD) relay is located in the engine compartment within the Power Distribution Center (PDC). Always refer to the label on the power distribution center cover for relay location.

1. Remove the power distribution center cover.
2. Remove the relay from the power distribution center.
3. Check the condition of the relay terminals and power distribution center connector terminals for damage or corrosion. Repair if necessary before installing the relay.
4. Check for pin height (pin height should be the same for all terminals within the power distribution center connector). Repair if necessary before installing the relay.

INSTALLATION

The Automatic Shutdown (ASD) relay is located in the engine compartment within the Power Distribution Center (PDC). Always refer to the label on the power distribution center cover for relay location.

The Camshaft Position (CMP) sensor is a Hall effect type sensor and is used by the Powertrain Control Module (PCM) in conjunction with the Crankshaft Position (CKP) sensor and TDC signal to recognize the position of the cylinders and determine the injection and ignition point. The CMP sensor is located on the camshaft bearing housing and faces the camshaft.

1. The camshaft position (CMP) sensor O-ring (1) can be reused if not damaged.
2. Apply a small amount of engine oil to the sensor O-ring (1).
3. Install the camshaft (CMP) sensor (1) with mounting bolt (2). Tighten the mounting bolt to 9 N.m (80 in. lbs.).
4. Connect and lock the camshaft position (CMP) sensor electrical connector (1).
5. Install the oil separator housing (4) to the cylinder head cover with three bolts (2) tightened to 13 N.m (115 in. lbs.).
6. Connect the vent hose (3) to the oil filler neck.
7. Connect the PCV hose (1) to the intake manifold.
8. Install the air cleaner body (6). Refer to «BODY, AIR CLEANER, INSTALLATION»(ref-646215-S04758408592014072800000) .
9. Install the negative battery cable and tighten nut to 5 N.m (45 in. lbs.).
10. Install the engine cover (1).

Note. The Cam/Crank Variation Relearn procedure must be performed using the scan tool anytime there has been a repair/replacement made to a powertrain system, for example: flywheel, valvetrain, camshaft and/or crankshaft sensors or components. Refer to appropriate Diagnostic Information .

Scheme 12

The knock sensor is the piezoelectric type and is fitted on the crankcase to detect the intensity of the vibrations caused by detonation in the combustion chambers. The phenomenon produces a mechanical repercussion on a piezoelectric crystal that sends a signal to the powertrain control module (PCM) and, on the basis of this signal, the PCM reduces the ignition advance until the phenomenon disappears. Later on, the advance is gradually restored to the basic value.

Scheme 13

The molecules of a quartz crystal are affected by electrical polarization. In rest conditions (A) the molecules are not arranged in a particular way. When the crystal is subjected to pressure or to an impact (B), the higher the pressure, the more marked their arrangement. This arrangement produces a voltage at the ends of the crystal.

Scheme 14

1. Disconnect and isolate the negative battery cable.
2. Raise and support the vehicle. Refer to «HOISTING, STANDARD PROCEDURE»(ref-646211-S00664313032014072800000) .
3. Remove the belly pan. Refer to «BELLY PAN, REMOVAL»(ref-646214-S24731623582014072800000) .
4. Remove the knock sensor electrical connector (1).
5. Remove the mounting bolt (3) and knock sensor (2).

1. Thoroughly clean the knock sensor mounting hole. CAUTION: Over or under tightening the knock sensor mounting bolt will affect knock sensor performance, possibly causing improper spark control. Always use the specified torque when installing the knock sensor. Do not apply any adhesive, sealant or thread locking compound to the bolt.
2. Install the knock sensor (2) with mounting bolt (3). Tighten the mounting bolt to 25 N.m (18 ft. lbs.).
3. Connect the electrical connector (1).
4. Install the belly pan. Refer to «BELLY PAN, INSTALLATION»(ref-646214-S07994234782014072800000) .
5. Lower the vehicle.
6. Connect the negative battery cable and tighten nut to 5 N.m (45 in. lbs.).

Note. Number 1 cylinder ignition coil shown in illustration, all others similar.

Scheme 16

1. Remove the ignition coil (2). Refer to «COIL, IGNITION, REMOVAL»(ref-646263-S23687984942014072800000) .
2. Prior to removing the spark plug, spray compressed air into the cylinder head opening. This will help prevent foreign material from entering the combustion chamber. CAUTION: The spark plug tubes (1) are a thin wall design. Avoid damaging the spark plug tubes. Damage to the spark plug tube can result in oil leaks.
3. Remove the spark plug from the cylinder head using a quality thin wall socket with a rubber or foam insert.
4. Inspect the spark plug condition.

Scheme 17

1. Check and adjust the spark plug gap with a gap gauging tool (1) Refer to «SPARK PLUGS»(ref-646263-S37411083322014072800000) . CAUTION: Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells as electrodes can be damaged. CAUTION: The spark plug tubes (1) are a thin wall design. Avoid damaging the spark plug tubes. Damage to the spark plug tube can result in oil leaks.
2. Start the spark plug into the cylinder head by hand to avoid cross threading.
3. Tighten the spark plugs to 16 N.m (12 ft. lbs.). NOTE: Number 1 cylinder ignition coil shown in illustration, all others similar.
4. Install the ignition coil (3) Refer to «COIL, IGNITION, INSTALLATION»(ref-646263-S16866518592014072800000) .
