TEST NTC-9A - CHECKING SOLENOID OPERATIONS

Note. For connector terminal identification, see CONNECTOR IDENTIFICATION in this article. For wiring diagram, see appropriate WIRING DIAGRAMS .

  1. Using DRB, actuate purge solenoid. While touching top of purge solenoid, feel for operation. If purge solenoid does not operate, replace purge solenoid. Perform «TEST VER-2»(ref-10877-S16703568862000111300000) .
  2. If purge solenoid operates, actuate EGR solenoid. While touching top of EGR solenoid, feel for operation. If EGR solenoid does not operate, replace EGR solenoid. Perform TEST VER-2. If EGR solenoid operates, test is complete.

TEST NS-7A - INSPECTING IDLE AIR CONTROL MOTOR OPERATION

Note. For connector terminal identification, see CONNECTOR IDENTIFICATION in this article. For wiring diagram, see appropriate WIRING DIAGRAMS .

  1. Disconnect Idle Air Control (IAC) motor connector. Turn ignition on. Using DRB, actuate IAC motor. Using DRB in voltmeter mode, check voltage on IAC motor connector, driver No. 3 circuit (Gray/Red wire on AB, AN and BR bodies). If voltage is less than one volt, go to TEST NS-7B.
  2. If voltage is more than one volt, check voltage on IAC motor connector, driver No. 1 circuit (Brown/White wire). If voltage is less than one volt, go to «TEST NS-7C»(ref-10877-S20779499432000111300000) .
  3. If voltage is more than one volt, check voltage on IAC motor connector, driver No. 4 circuit (Violet/Black wire on AB, AN and BR bodies). If voltage is less than one volt, go to «TEST NS-7D»(ref-10877-S02589309502000111300000) .
  4. If voltage is more than one volt, check voltage on IAC motor connector, driver No. 2 circuit (Yellow/Black wire on AB, AN and BR bodies). If voltage is less than one volt, go to «TEST NS-7E»(ref-10877-S24612009172000111300000) .
  5. If voltage is more than one volt, turn ignition off. Remove IAC motor from throttle body. Reconnect IAC motor connector. Turn ignition on. Using DRB, actuate IAC motor. If IAC motor pintle moves in and out, go to «TEST NS-8A»(ref-10877-S38592155882000111300000) . If IAC motor pintle does not move in and out, replace IAC motor. Perform «TEST VER-1»(ref-10877-S34287435522000111300000) .

TEST NS-7B - INSPECTING IDLE AIR CONTROL MOTOR OPERATION

Note. For connector terminal identification, see CONNECTOR IDENTIFICATION in this article. For wiring diagram, see WIRING DIAGRAMS .

  1. Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Inspect connectors for damaged, pushed-out or miswired terminals. Repair as required. Perform «TEST VER-1»(ref-10877-S34287435522000111300000) . If PCM terminals are okay, go to next step.
  2. Using an external ohmmeter, check resistance of driver No. 3 circuit (Gray/Red wire on AB, AN and BR bodies) between IAC motor connector and PCM connector terminal No. 39. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-1. If resistance is more than 5 ohms, repair open Gray/Red wire or Yellow/Black wire. Perform TEST VER-1.

TEST NS-7C - INSPECTING IDLE AIR CONTROL MOTOR OPERATION

Note. For connector terminal identification, see CONNECTOR IDENTIFICATION in this article. For wiring diagram, see appropriate WIRING DIAGRAMS .

  1. Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Inspect connectors for damaged, pushed-out or miswired terminals. Repair as required. Perform «TEST VER-1»(ref-10877-S34287435522000111300000) . If PCM terminals are okay, go to next step.
  2. Using an external ohmmeter, check resistance of driver No. 1 circuit (Brown/White wire) between IAC motor connector and PCM connector terminal No. 40. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-1. If resistance is more than 5 ohms, repair open Brown/White wire. Perform TEST VER-1.

TEST NS-7D - INSPECTING IDLE AIR CONTROL MOTOR OPERATION

Note. For connector terminal identification, see CONNECTOR IDENTIFICATION in this article. For wiring diagram, see appropriate WIRING DIAGRAMS .

  1. Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Inspect connectors for damaged, pushed-out or miswired terminals. Repair as required. Perform «TEST VER-1»(ref-10877-S34287435522000111300000) . If PCM terminals are okay, go to next step.
  2. Using an external ohmmeter, check resistance of driver No. 4 circuit (Violet/Black wire on AB, AN and BR bodies) between IAC motor connector and PCM connector terminal No. 59. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-1. If resistance is more than 5 ohms, repair open Violet/Black wire. Perform TEST VER-1.

TEST NS-7E - INSPECTING IDLE AIR CONTROL MOTOR OPERATION

Note. For connector terminal identification, see CONNECTOR IDENTIFICATION in this article. For wiring diagram, see appropriate WIRING DIAGRAMS .

  1. Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Inspect connectors for damaged, pushed-out or miswired terminals. Repair as required. Perform «TEST VER-1»(ref-10877-S34287435522000111300000) . If PCM terminals are okay, go to next step.
  2. Using external ohmmeter, check resistance of driver No. 2 circuit (Yellow/Black wire on AB, AN and BR bodies) between IAC motor connector and PCM connector terminal No. 60. If resistance is more than 5 ohms, repair open Yellow/Black wire or Violet/Black wire. Perform TEST VER-1. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-1.
