Test TC-41A - Manifold Tune Valve Solenoid Circuit (DTC 65)

WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION DIRECTORY . For wiring diagrams, see WIRING DIAGRAMS section. After each repair, perform TEST VER-2 .

Using DRB, erase trouble codes. Actuate Manifold Tuning Valve (MTV) solenoid. Read trouble codes. If DRB displays MANIFOLD TUNE VALVE SOLENOID CIRCUIT, go to step 4). If DRB does not display MANIFOLD TUNE VALVE SOLENOID CIRCUIT, go to next step.
At this time, the condition required to set trouble code is not present. MANIFOLD TUNE VALVE SOLENOID CONTROL CIRCUIT trouble code sets if the solenoid is not in its proper state when monitored by Powertrain Control Module (PCM). Possible causes are: open or shorted control circuit, open ignition 12-volt feed to solenoid, open or shorted solenoid, or failed PCM. Go to next step.
Inspect wiring and connectors. Repair as required. If wiring and connectors are okay, with actuator test still running, erase trouble codes. Wiggle wiring harness from solenoid to PCM. If MANIFOLD TUNE VALVE SOLENOID CIRCUIT trouble code returns, repair wiring where wiggling caused problem to appear. If MANIFOLD TUNE VALVE SOLENOID CIRCUIT trouble code does not return, see INACTIVE TROUBLE CODE CONDITION . Test is complete.
If DRB displays MANIFOLD TUNE VALVE SOLENOID CIRCUIT in step 1), turn ignition off. Disconnect MTV solenoid connector. MTV solenoid is located on right front strut tower. Turn ignition on. Using DRB in voltmeter mode, check voltage on MTV solenoid connector terminal No. 2 (Light Green/Black wire). If voltage is less than 10 volts, go to TEST TC-41B . If voltage is more than 10 volts, go to next step.
Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. PCM is located under air cleaner. Using an external ohmmeter, check resistance of Violet/White between MTV solenoid connector terminal No. 1 and PCM connector terminal No. 36. If resistance is more than 5 ohms, repair open Violet/White wire If resistance is less than 5 ohms, go to next step.
Using DRB in ohmmeter mode, check resistance of PCM connector terminal No. 36 (Violet/White wire). If resistance is less than 5 ohms, repair short to ground in Violet/White wire. If resistance is more than 5 ohms, go to next step.
Reconnect MTV solenoid connector. Turn ignition on. Using DRB in voltmeter mode, check voltage on PCM connector terminal No. 36 (Violet/White wire). If voltage is less than 10 volts, replace MTV solenoid. If voltage is more than 10 volts, replace PCM.
