1A-168 Engine General Information and Diagnosis:
Step
9
Ground circuit check
1) Remove ECM from its bracket with ECM connectors
connected.
2) Check for proper connection of ECM connector at "E23-
51" terminal.
3) If OK, measure resistance between "E23-51" terminal of
ECM connector and engine ground.
Is resistance below 5
10 APP sensor check
1) Check APP sensor (sub) referring to "APP Sensor
Assembly Inspection in Section 1C".
Is output voltage within specified value?
