Idle Air Control Motor
NOTE:
For idle air control motor circuit testing, see DTC P0505: IDLE AIR CONTROL MOTOR CIRCUITS
under DIAGNOSTIC TESTS in SELF-DIAGNOSTICS - SEBRING CONVERTIBLE, SEBRING SEDAN & STRATUS SEDAN article.
NOTE:
For circuit identification and wiring diagram, see WIRING DIAGRAMS
article. After each repair procedure has been completed, reconnect all components. Perform POWERTRAIN VERIFICATION TEST VER-2
under VERIFICATION TESTS to ensure system is functioning properly.
- Turn ignition on. Using scan tool, set engine speed to 1400 RPM. If engine speed does not reach 1400 RPM, go to next step. If engine speed reaches 1400 RPM, IAC motor is operating properly. Test is complete.
- Turn ignition off. Disconnect IAC motor and PCM harness connectors. IAC motor is located on throttle body. IAC motor is located on side of throttle body. PCM is located on left side of engine compartment, near air filter housing. See Figure . Inspect connectors for damaged pins, corrosion and loose terminals. Repair connectors as necessary. If connectors are okay, measure resistance of each wire between IAC motor harness connector and PCM C2 harness connector. See Figure and Fig 1 . If each resistance is less than 5 ohms, replace IAC motor. If any resistance is 5 ohms or more, repair open in appropriate wire between IAC motor and PCM.
