1.
Check APS
(1)
Ignition "OFF"
(2)
Disconnect APS connector.
(3)
Check that resistance is getting lower by pressing APS to wide open.
(4)
Measure resistance between terminal 2 and 5 of APS connector (Component side).
Specification : 1.2kΩ ± 0.4kΩ (20°C)
(5)
Is the measured resistance within specifications?
YES
▶ Substitute with a known-good ECM and check for proper operation.
If the problem is corrected, replace ECM and then go to "Verification of Vehicle Repair" procedure.
NO
▶ Substitute with a known-good APS and check for proper operation.
