Test TC-15A - Injector #3 Control Circuit (DTC 27)
WARNING: This page is about a different car, the 1994 Plymouth Acclaim and 1994 Dodge Spirit. However, it is still accessible from the selected car via links, so may be relevant.

- Turn ignition off. Disconnect injector No. 3 connector (Yellow/White and Dark Green/Black wires). Using an external ohmmeter, check injector resistance. If resistance is not 2-5 ohms, replace injector No. 2. Perform TEST VER-2.
- If resistance is 2-5 ohms, turn ignition on. Using DRB, actuate injector No. 3. Using DRB, check voltage on injector No. 3 connector (Dark Green/Black wire). If voltage is less than 10 volts, repair open in Dark Green/Black wire. Perform TEST VER-2.
- If voltage is more than 10 volts, turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Using an external ohmmeter, check resistance of Yellow/White wire between injector No. 3 connector and PCM connector terminal No. 14. If resistance is more than 5 ohms, repair open in Yellow/White wire. Perform TEST VER-2 .
- If resistance is less than 5 ohms, put DRB in ohmmeter mode. Using DRB, check resistance of PCM connector terminal No. 14 (Yellow/White wire). If resistance is less than 5 ohms, repair short to ground in Yellow/White wire. Perform TEST VER-2. If resistance is more than 5 ohms, replace PCM. Perform TEST VER-2.
