DTC P1768/16: Linear Solenoid

WARNING: This page is about a different variant/trim than selected.
NOTE: For circuit and terminal identification, see CONNECTOR IDENTIFICATION  and WIRING DIAGRAMS  .
  1. Using scan tool, retrieve freeze data. Clear DTCs and road test vehicle under same conditions freeze data was recorded. If DTC resets, go to next step. If DTC does not reset, problem is intermittent, check transaxle and PCM connections.
  2. Disconnect linear solenoid harness connector. Measure resistance between terminals of linear solenoid valve. If resistance is about 5 ohms, go to next step. If resistance is not as specified, replace linear solenoid assembly. See LINEAR SOLENOID ASSEMBLY  under REMOVAL & INSTALLATION.
  3. Disconnect PCM harness connector "B". Check for continuity between PCM harness connector "B" terminal No. 17 (Red wire) and ground, and between terminal No. 8 (White wire) and ground. If continuity is not present, go to next step. If continuity is present, repair short to ground in Red wire and/or White wire.
  4. Connect linear solenoid harness connector. Measure resistance between PCM harness connector "B" terminals No. 17 (Red wire) and No. 8 (White wire). If resistance is about 5 ohms, go to next step. If resistance is not as specified, repair open or poor connection in Red wire and/or White wire between linear solenoid and PCM harness connector "B".
  5. Disconnect PCM harness connector "D". Turn ignition on. Measure voltage between PCM harness connector "D" terminal No. 5 (Black/Yellow wire) and connector "B" terminal No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check fuse No. 15 (7.5 amp) in underdash fuse/relay box. If fuse is okay, repair open between PCM harness connector "D" and underdash fuse/relay box.
  6. Check for continuity between PCM harness connector "B" terminal No. 20 and ground, and between terminal No. 22 and ground. If continuity is not present, repair open in Brown/Black wire(s). If continuity is present, check for loose PCM harness connectors. Repair as necessary. If connectors are okay, substitute a known-good PCM and retest system.
