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-h ...

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 ...
Inspection
1. Intake air flow meter sub–assy
Inspect the intake air flow meter resistance.
Using an ohmmeter, measure the resistance between
terminals tha and e2.
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 ...
