Mirage L4-1597cc 1.6L DOHC (1990)
HARNESS TEST
1. Disconnect the EGR solenoid connector and turn the key to the ON position.
2. Using a voltmeter, measure the power supply voltage between the harness connector terminal 1 and ground.
Voltage:
System voltage.
3. Turn the key OFF and disconnect the negative battery cable.
4. Using an Ohmmeter, check for continuity between the ECU harness connector terminal 53 and and solenoid connector 2.
Continuity:
Should exist.
5. Disconnect the ECU connector. Using an Ohmmeter, check for continuity between the ECU harness connector terminal 53 and ground.
Continuity:
Should not exist.
6. Using an Ohmmeter, check for continuity between the solenoid connector terminal 2 and ground.
Continuity:
Should not exist.
If any of the previous tests produce unsatisfactory results, the harness will need to be repaired or replaced. Once repairs have been completed, clear
the trouble codes and road test the vehicle to confirm that the repair has corrected the problem and the code doesn't return.
If the trouble code returns, it is possible that there is an intermittent failure of the component or the ECU. Check for looseness at all harness
junctions and test for an intermittent failure.
