Test TC-20A - Injector No. 2 Control Circuit

NOTE: For connector terminal ID, see CONNECTOR IDENTIFICATION  Directory. For wiring diagram, see appropriate WIRING DIAGRAMS - NON-TURBO article.
  1. Turn ignition off. It may be necessary to remove intake plenum for access to injector connectors. Disconnect injector No. 2 connector. Using an external ohmmeter, check resistance across injector No. 2 terminals. If resistance is 10-16 ohms, go to next step. If resistance is not 10-16 ohms, replace injector No. 2. Perform TEST VER-2A.
  2. Turn ignition on. Using scan tool, actuate ASD relay. Using scan tool in voltmeter mode, check voltage on injector No. 2 connector ASD relay output circuit (Black/Red wire). If voltage cycles high and low, go to next step. If voltage does not cycle high and low, repair open ASD relay output circuit. Perform TEST VER-2A.
  3. Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Using scan tool in ohmmeter mode, check resistance of PCM connector terminal No. 17 injector No. 2 driver circuit (Yellow/Red wire). If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, repair short to ground on injector No. 2 driver circuit. Perform TEST VER-2A.
  4. Using an external ohmmeter, check resistance of injector No. 2 driver circuit (Yellow/Red wire). If resistance is less than 5 ohms, replace PCM. Perform TEST VER-2A. If resistance is 5 ohms or more repair open injector No. 2 driver circuit. Perform TEST VER-2A.
