Test NTC-11A - Checking Pcm Ground & Power Circuits
1994 Plymouth Voyager LE, 3.3 RSECTION Test NTC-11A - Checking Pcm Ground & Power Circuits
NOTE:
For circuit and connector terminal identification, see CONNECTOR IDENTIFICATION in this article. For wiring diagrams, see WIRING DIAGRAMS .
- Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Using DRB in ohmmeter mode, check resistance of PCM connector terminal No. 5 (Black/White wire). If resistance is more than 5 ohms, repair open in Black/White wire. Perform TEST VER-2 . If resistance is less than 5 ohms, go to next step.
- Using DRB, check resistance of PCM connector terminal No. 11 Black/Tan wire. If resistance is more than 5 ohms, repair open in Black/Tan wire. Perform TEST VER-2. If resistance is less than 5 ohms, go to next step.
- Using DRB, check resistance of PCM connector terminal No. 12 (Black/Tan wire). If resistance is more than 5 ohms, repair open in Black/Tan wire. Perform TEST VER-2. If resistance is less than 5 ohms, go to next step.
- Put DRB in voltmeter mode. Turn ignition on. Using DRB, check voltage on PCM connector terminal No. 9 (Dark Blue wire). If voltage is less than 10 volts, repair open in Dark Blue wire. Perform TEST VER-2. If voltage is more than 10 volts, turn ignition off. Reconnect PCM connector. PCM grounds and power circuits are okay. Test is complete.

- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
