High–Tension Cord Inspection; Inspect High–Tension Cord Resistance & Terminals; Clean And Inspect Spark Plugs - Toyota 22R-E Service Manual

IG–6
IGNITION SYSTEM – (22R– E)
HIGH–TENSION CORD INSPECTION
1. CAREFULLY REMOVE HIGH–TENSION CORDS BY
THEIR RUBBER BOOTS FROM SPARK PLUGS
CAUTION: Do not pull on or bend the cords to avoid
damaging the conductor inside.
2. INSPECT HIGH–TENSION CORD TERMINALS
Check the terminals for corrosion, breaks or distor–
tion.
Replace cords as required.
3. INSPECT HIGH–TENSION CORD RESISTANCE
Using an ohmmeter, check that the resistance does
not exceed the maximum.
Maximum resistance:
25 kW per cord
If the resistance exceeds maximum, check the termi–
nals. If any defect has been found, replace the high–
tension cord and/or distributor cap.
SPARK PLUGS INSPECTION
1. REMOVE SPARK PLUGS

2. CLEAN AND INSPECT SPARK PLUGS

(a) Clean the spark plugs with a spark plug cleaner or wire
brush.
(b) Inspect the spark plugs for electrode wear, thread
damage and insulator damage.
If a problem is found, replace the plugs.
Spark plug:
ND W16EXR–U
NGK BPR5EY
3. ADJUST ELECTRODE GAP
Carefully bend the outer electrode to obtain the cor–
rect electrode gap.
Correct electrode gap:
0.8 mm (0.031 in.)
4. INSTALL SPARK PLUGS
Torque: 18 N–m (180 kgf–cm, 13 ft–lbf)
