1. Intake air flow meter sub–assy
Resistance:
at –20 c (–4 f) 13.6 To 18.4 KΩ
at 20 c (68 f) 2.21 To 2.69 KΩ
at 60 c (140 f) 0.49 To 0.67 KΩ
Hint
: if the resistance is not as specified, replace the intake air flow meter.
Hint
: if operation is not as specified, replace the intake air flow meter.
2. Camshaft timing oil control valve assy
Resistance: 6.9 To 7.9 W at 20 c (68 f)
Notice
: confirm the valve does not adhere.
Hint
: bad returning of the valve by entrance of foreign objects causes subtle pressure leak to the advanced direction. Then, dtc can be detected.
3. Throttle body assy
Notice
: do not adjust the throttle stop screw.
4. E.F.I. Throttle position sensor
Resistance: 2.5 To 6.0 KΩ
Change of resistance: the resistance value increases in proportion to the throttle lever opening value.
Hint:
5. E.F.I. Engine coolant temperature sensor
Resistance:
at 20 c (68 f) 2.32 – 2.59 KΩ
at 80 c (176 f) 0.310 – 0.326 KΩ
Notice
: in case of checking the water temperature sensor in the water, be careful not to allow water to go into the terminals, and after checking, wipe out the sensor.
6. Knock control sensor
Resistance: 120 – 280 kΩ at 20 c (68 f)
Hint
: if the resistance is not specified, replace the sensor.
7. E.F.I. Circuit opening relay assy
Specified condition:
between terminals 1 and 2 continuity
between terminals 3 and 5 no continuity
8. E.F.I ecu relay
Specified condition:
between terminals 1 and 2 continuity
between terminals 3 and 5 no continuity

Inspection procedure
Hint:
if different dtcs related to different systems that have terminal e2
as the ground terminal are output
simultaneously, terminal e2 may be open.
Read freeze frame data using the hand-held tester or the obd ii scan
tool. Freeze frame data records

Inspection procedure
Hand–held tester:
1 Check operation of stop light
Check if the stop lights go on and off normally when the brake pedal is
depressed and released.
2 Inspect stop light switch assy
Check the resistance between the terminals when the
switch is turned on and off.
Standard:
