Toyota Corolla Repair Manual: Inspection
1. Spark plug
Notice
:
- never use a wire brush for cleaning.
- Never attempt to adjust the electrode gap on used spark plug.
- Spark plug should be replaced every 192,000 km (120,000 miles).
- Clean the spark plugs.
Air pressure: below 588 kpa (6.0 Kg/cm2, 85 psi) duration: 20 seconds or less
- Check the spark plug for thread damage and insulator damage.
Hint
: if abnormal, replace the spark plug.
Recommended spark plug:
sk16r11 (denso made)
ifr5a11 (ngk made)
- Check the spark plug electrode gap.
Electrode gap: 1.1 Mm (0.043 In.)
2. Crank position sensor no.1
- using an ohmmeter, measure the resistance between terminals.
Resistance:
at cold 835 – 1,400 w
at hot 1,060 – 1,645 w
N
otice
: ”cold” and ”hot” on the table express the temperature of the coils themselves. ”Cold” is from –10 c (14 f) to 50 c (122 f) and ”hot” is from 50 c (122 f) to 100 c (212 f).
Hint
: if the resistance is not as specified, replace the crank position sensor no. 1.
3. Crank position sensor
- using an ohmmeter, measure the resistance between terminals.
Resistance:
at cold 1,630 – 2,740 w
at hot 2,065 – 3,225 w
Notice
: ”cold” and ”hot” on the table express the temperature of the coils themselves. ”Cold” is from –10 c (14 f) to 50 c (122 f) and ”hot” is from 50 c (122 f) to 100 c (212 f).
Hint
: if the resistance is not as specified, replace the crank position sensor.
4. Ignition relay
- Continuity inspection.
- Using an ohmmeter, check that continuity exists between
each terminal.
Specified condition: between terminal 1 and 2 continuity between terminal 3 and 5 no continuity
- using an ohmmeter, check that continuity exists between terminals 3 and 5 when the battery voltage is applied across terminals 1 and 2.
On–vehicle inspection
Notice:
”cold” and ”hot” in these sentences express the temperature of the coils
themselves. ”Cold” is from
–10 c (14 f) to 50 c (122 f) and ”hot” is from 50 c (122 f) to 100 c (212 f).

On–vehicle inspection
1. Inspect refrigerant pressure with manifold gauge set
this is a method in witch the trouble is located by using
a manifold gauge set. Read the manifold gauge pressure
when the these conditions are established.
Test conditions:
temperature at the air inlet with the switch set
...
Inspection procedure
Hint:
start the inspection from step 1 in case of using the hand–held tester and start
from step 2 in case of not
using the hand–held tester.
1 Read value of hand–held tester(front speed sensor)
Select the datalist mode on the hand–held tester.
check that there is no difference betw ...
