1986 TOYOTA CAMRY V20 spark plugs

ON±VEHICLE INSPECTION (3S±FE)
SPARK TEST
CHECK THAT SPARK OCCURS
(a) Disconnect the high±tension cords from the spark plugs.
(b) Remove the spark plugs.
(c) Install the spark plugs to each high±tension cord.
(d) Ground the spark plug.
(e) Check if spark occurs while engine is being cranked.
HINT: To prevent gasoline from being injected from injectors
during this test, crank the engine for no more than 1
± 2 seconds at a time.
If the spark does not occurs, perform the test as follows:
CHECK RESISTANCE OF IGNITION COIL
(See page IG±7)
Resistance (Cold):
Primary 0.38 ± 0.46


Secondary 7.7 ± 10.4 k

CHECK POWER SUPPLY TO IGNITION
COIL AND IGNITER
1. Ignition switch turn to ON.
2. Check that there is battery voltage at
ignition coil positive (+) terminal. CHECK RESISTANCE OF HIGH±TENSION
CORD (See page IG±6)
Maximum resistance: 25 k
per cord
CHECK RESISTANCE OF SIGNAL
GENERATOR (PICKUP COIL) (See page
IG±8) Resistance: 140 ± 180


CHECK AIR GAP OF DISTRIBUTOR
(See page IG±7)
Air gap: 0.2 mm (0.008 in.) or moreCHECK CONNECTION OF IGNITION
COIL, IGNITER AND DISTRIBUTOR

Check wiring between ignition switch
to ignition coil and igniter.

2. INSPECT HIGH±TENSION CORD RESISTANCE
Using an ohmmeter, measure the resistance without discon-
necting the distributor cap.
Maximum resistance: 25 k

per cord
If the resistance is greater than maximum, check the termi-
nals. If necessary, replace the high±tension cord and/
or distributor cap.
3. VISUALLY INSPECT SPARK PLUGS
Check the spark plug for electrode wear, thread damage or
insulation damage.
If abnormal, replace the spark plug.
Recommended spark plug: ND Q1 6R±U11

INSPECTION OF HIGH±TENSION
CORDS
1. CAREFULLY REMOVE HIGH±TENSION CORDS BY
THEIR RUBBER BOOTS FROM SPARK PLUGS
NOTICE: Pulling on or bending the cords may damage the
conductor inside.
INSPECTION OF SPARK PLUGS
1. REMOVE SPARK PLUGS
Using a 16 mm plug wrench, remove the spark plug.
2. CLEAN SPARK PLUG
Using a spark plug cleaner or wire brush, clean the spark
plug.

INSPECTION OF DISTRIBUTOR
1. INSPECT AIR GAP
Using a feeler gauge, measure the gap between the signal
rotor and pickup coil projection.
Air gap: 0.2 mm (0.008 in.) or more
If the air gap is not as specified, replace the distributor
housing assembly.INSPECTION OF IGNITION COIL
1. INSPECT PRIMARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between posi-
tive (+) and negative (±) terminals.
Primary coil resistance (Cold): 0.38 ± 0.46

If the resistance is not as specified, replace the ignition coil.
2. INSPECT SECONDARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between the
positive (+) and high±tension terminals.
Secondary coil resistance (Cold): 7.7 ±10.4 k


If the resistance is not as specified, replace the ignition coil.4. ADJUST ELECTRODE GAP
Carefully bend the outer electrode to obtain the correct elec-
trode gap.
Correct electrode plug: 1.1 mm (0.043 in.)
5. INSTALL SPARK PLUGS
Using a 16 mm plug wrench, install the spark plug.
Torque: 180 kg±cm (13 ft±lb, 18 N±m)

INSPECTION OF SPARK PLUGS
NOTICE:
wNever use a wire brush for cleaning
wNever attempt to adjust the electrode gap on used
spark plug.
wSpark plug should be replaced every 100,000 km
I60,000 miles).
6. If not using a megger:
(a) Quickly race the engine to 4,000 rpm five times.
(b) Remove the spark plug.
(See step 2 on page IG±11)
(C) Visually check the spark plug.
If the electrode is dry ... Okay
If the electrode is wet ... Proceed to step 3 INSPECTION OF HIGH±TENSION CORDS
1. CAREFULLY REMOVE HIGH±TENSION CORDS BY
THEIR RUBBER BOOTS FROM SPARK PLUGS
NOTICE: Pulling on or bending the cords may damage the
conductor inside.
1. INSPECT ELECTRODE
A. If using a megger (insulation resistance motor):
Measure the insulation resistance.
Correct insulation resistance: 10 M

or more
If the resistance is less than specified, proceed step 2. 2. INSPECT HIGH±TENSION CORD RESISTANCE
Using an ohmmeter, measure the resistance.
Maximum resistance: 25 k

per cord
If the resistance is greater than maximum, replace the high±
tension cord.

4. INSPECT ELECTRODE GAP
Maximum electrode gap: 1.3 mm, (0.051 in.)
If the gap is greater than maximum, replace the spark plug.
Correct electrode gap of new spark plug:
1.1 mm (0.043 in.)
If adjusting the gap of a new spark plug, bend only the base
of the ground electrode. Do not touch the tip.
5. CLEAN SPARK PLUGS
If the electrode has traces of wet carbon, allow it to dry and
then clean with a spark plug cleaner.
Air pressure: Below6 kg/cm
2 (85 psi, 588 kPa)
Duration: 20 seconds or less
HINT: If there are traces of oil, remove it with gasoline before
using the spark plug cleaner.3. VISUALLY INSPECT SPARK PLUGS
Check the spark plug for thread or insulation damage.
If abnormal, replace the spark plug.

6. INSTALL SPARK PLUGS
Using a 16 mm plug wrench, install and torque the spark
plug.
Torque: 180 kg±cm (13 ft±Lb, 18 N±m)
