Symptom List:
P0506-IDLE SPEED LOW PERFORMANCE
P0507-IDLE SPEED HIGH PERFORMANCE
P0519-IDLE SPEED PERFORMANCE
Test Note: All symptoms listed above are diagnosed using the same tests.
The title for the tests will be P0506-IDLE SPEED LOW PER-
FORMANCE.
When Monitored and Set Condition:
P0506-IDLE SPEED LOW PERFORMANCE
When Monitored: Engine Running. During an idle condition.
Set Condition: If the engine RPM does not come within a calibratable low limit of the
target idle speed, a failure timer will increment. When the appropriate failure timer
reaches its maximum threshold without sign of RPM trending towards control, a soft fail
is generated. When a calibratable number of the soft fails is reached, a I trip fault is set.
When two 1 trip faults occur in a row, a the DTC is set and the MIL illuminates.
P0507-IDLE SPEED HIGH PERFORMANCE
When Monitored: Engine Running. During an idle condition.
Set Condition: If the engine RPM does not come within a calibratable high limit of the
target idle speed, a failure timer will increment. When the appropriate failure timer
reaches its maximum threshold without sign of RPM trending towards control, a soft fail
is generated. When a calibratable number of the soft fails is reached, a I trip fault is set.
When two 1 trip faults occur in a row, a the DTC is set and the MIL illuminates.
P0519-IDLE SPEED PERFORMANCE
When Monitored: With the engine idling and the transmission in drive, if automatic.
There must not be a MAP sensor trouble code or a Throttle Position Sensor trouble code.
Set Condition: The engine idle is not within 200 rpm above or 100 rpm below the target
idle for 50 seconds. Two trip fault.
