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
Circuit description
When the idle switch is turned on, a signal is sent to the cruise control ecu
assy. The cruise control ecu
assy uses this signal to correct the discrepancy between the throttle valve
position and the actuator position
sensor values to enable accurate cruise control at the set speed. If the idl ...
