Question about 1998 Ford Explorer
Daughters car keeps giving this code, yet she says it still runs fine. Can any one help
Diagnostic Trouble Code (DTC) P1505 indicates the IAC system has reached the adaptive clip.
Whenever an IAC component is replaced or cleaned or a service affecting idle is performed, it is recommended that KAM be cleared. This is necessary so the idle strategy does not use the previously learned adaptive values.
To clear KAM, refer to PCM Reset in Section 2. It is important to note that erasing DTCs with a scan tool does not reset the adaptive idle table.
Once KAM has been reset, the engine must idle for fifteen minutes (actual time varies between strategies) to learn new adaptive values. Idle quality will improve as the strategy adapts. Adaptation occurs in four separate modes. The modes are transmission select in neutral with air conditioning on; transmission select in neutral with air conditioning off; transmission select in drive with air conditioning on; and transmission select in drive with air conditioning off.
