Pinpoint Test E: Transaxle Solenoid Pressure Control Circuit

WARNING: This page is about a different variant/trim than selected.
NOTE: Refer to the TRANSAXLE VEHICLE HARNESS CONNECTOR  illustration within the Transaxle Connector Layouts procedure  in this service information.
  1. E1 CHECK FOR VOLTAGE AT THE TRANSAXLE VEHICLE HARNESS CONNECTOR 
    • Disconnect: Transaxle Vehicle Harness C168A.
    • Use a mirror to inspect both ends of the connector for damage or pushed-out pins, corrosion, loose wires and missing or damaged seals.
    • Ignition ON.
    • Measure the voltage between the transaxle vehicle harness C168A-5, circuit CET25 (BU/GN) and ground.

    • Is the voltage greater than 10 volts? 
    1. Yes:  INSTALL a new Transaxle Pressure Control Solenoid. Refer to SOLENOIDS  in this service information. RECONNECT all components. TEST the system for normal operation.
    2. No:  Go to E2  .
  2. E2 CHECK THE TRANSAXLE SOLENOID PRESSURE CONTROL CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • Disconnect: PCM Transaxle Harness C175T.
    • Measure the resistance between the PCM transaxle C175T-50, circuit CET25 (BU/GN) and transaxle vehicle harness C168A-5, circuit CET25 (BU/GN).

    • Is the resistance less than 5 ohms? 
    1. Yes:  Go to E3  .
    2. No:  REPAIR circuit CET25 (BU/GN) for an open. RECONNECT all components. TEST the system for normal operation.
  3. E3 CHECK THE TRANSAXLE SOLENOID POWER CONTROL CIRCUIT FOR A SHORT TO GROUND 
    • Measure the resistance between the transaxle vehicle harness C168A-5, circuit CET25 (BU/GN) and ground.

    • Is the resistance greater than 10, 000 ohms? 
    1. Yes:  INSTALL a new PCM. Refer to ELECTRONIC ENGINE CONTROLS - 2.5L article or ELECTRONIC ENGINE CONTROLS - 3.0L (4V) article. RECONNECT all components. TEST the system for normal operation.
    2. No:  REPAIR circuit CET25 (BU/GN) for a short to ground. RECONNECT all components. TEST the system for normal operation.
