KNOCK SENSOR (Continued)
NOTE: Over or under tightening affects knock sen-
sor performance, possibly causing improper spark
control.
REMOVAL
REMOVAL - 4 CYLINDER
The knock sensor threads into the side of the cyl-
inder block (Fig. 10).
Fig. 10 KNOCK SENSOR - 4 CYLINDER
(1) Disconnect electrical connector from knock sen-
sor.
(2) Use a crow foot socket to remove the knock
sensors.
REMOVAL - 2.7L
The sensors screws into the cylinder block, directly
below the intake manifold.
(1) Remove intake manifold plenum refer to the
Engine section.
(2) Remove the passenger side cylinder head, refer
to the Engine section.
(3) Disconnect electrical connector from knock sen-
sor (Fig. 11).
(4) Use a crows foot socket to remove the knock
sensors.
INSTALLATION
INSTALLATION - 4 CYLINDER
The knock sensor threads into the side of the cyl-
inder block in front of the starter (Fig. 10).

(1) Install knock sensor. Tighten knock sensor to
10 N·m (7 ft. lbs.) torque. Over or under tighten-
ing effects knock sensor performance, possibly
causing improper spark control.
(2) Attach electrical connector to knock sensor.

SPARK PLUG
DESCRIPTION
DESCRIPTION - STANDARD 4 CYLINDER
All engines use resistor spark plugs. They have
resistance values ranging from 6,000 to 20,000 ohms
when checked with at least a 1000 volt spark plug
tester.
Do not use an ohm meter to check the resis-
tance of the spark plugs. This will give an inac-
curate reading.
Refer to the Specifications section for gap and type
of spark plug.
