Toyota Highlander Service Manual: Inspection
NOTICE: In this section, the terms "cold"and "hot" refer to the temperature of the coils. "Cold" means approximately -10 C (14 F) to 50 C (122 F). "Hot" means approximately 50 C (122 F) to 100 C (212 F).
1. INSPECT SPARK PLUG
NOTICE:
- Do not use a wire brush for cleaning.
- Do not attempt to adjust the electrode gap of a used spark plug.
(a) Check the electrode.
- Using a megaohmmeter, measure the insulation resistance.
Correct insulation resistance: 10 MW or higher
If the resistance is less than the specified value, proceed to step (d).
HINT: If a megaohmmeter is not available, do the following simple inspection instead.
(b) Alternative inspection method:
- Quickly accelerate the engine to 4,000 rpm 5 times.
- Remove the spark plug.
- Visually check the spark plug.
- If the electrode is dry, the spark plug is functioning.
Proceed to step 2.
- If the electrode is damp, proceed to step (c), (d), and (e).
- Install the spark plug.
- Check the spark plug for any damage on its thread and insulator.
If there is damage, replace the spark plug.
Recommended spark plug:
(d) Check the spark plug electrode gap.
Maximum electrode gap for used spark plug: 1.3 mm (0.051 in.)
If the gap is greater than the maximum, replace the spark plug.
Correct electrode gap for new spark plug: 1.0 to 1.1 mm (0.039 to 0.043 in.)
NOTICE: If adjusting the gap of a new spark plug, bend only the base of the ground electrode. Do not touch the tip. Never attempt to adjust the gap on a used plug.
(e) Clean the spark plugs.
If the electrode has traces of wet carbon, clean the electrode with a spark plug cleaner and then dry it.
Air pressure: 588 kPa (6 kgf/cm2, 85 psi) Duration: 20 seconds or less
HINT: Only use the spark plug cleaner when the electrode is free of oil. If the electrode has traces of oil, use gasoline to clean off the oil before using the spark plug cleaner.
2. INSPECT CAMSHAFT POSITION SENSOR
(a) Using an ohmmeter, measure the resistance between the terminals.
Standard:
If the result is not as specified, replace the sensor.
3. INSPECT CRANKSHAFT POSITION SENSOR
(a) Using an ohmmeter, measure the resistance between the terminals.
Standard:
If the result is not as specified, replace the sensor.
On-vehicle inspection
NOTICE:
In this section, the terms "cold" and "hot" refer to the temperature of the
coils. "Cold"means approximately
-10 C (14 F) to 50 C (122 F). "Hot" means approximately 50 C (122 F) to 100 C
