Test TC-17B: EGR Solenoid Circuit

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS article.
  1. Turn ignition off. Disconnect EGR solenoid connector. Turn ignition on. Using scan tool, actuate EGR solenoid. Using a voltmeter, check voltage of ASD relay output circuit at EGR solenoid connector (Dark Green/Orange wire). If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair open Dark Green/Orange wire. Perform TEST VER-2A .
  2. Turn ignition off. Disconnect PCM connector. Using an ohmmeter, check resistance of EGR solenoid control circuit (Gray/Yellow wire) between EGR solenoid connector and PCM connector terminal No. 40. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or more, repair open Gray/Yellow wire. Perform TEST VER-2A .
  3. Using an ohmmeter, check resistance of Gray/Yellow wire between EGR solenoid connector and ground. If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, repair short to ground on Gray/Yellow wire. Perform TEST VER-2A .
  4. Using an ohmmeter, check resistance of EGR solenoid. If resistance is 25-75 ohms, replace PCM. Perform TEST VER-2A . If resistance is not 25-75 ohms, replace EGR solenoid. Perform TEST VER-2A .
