Code 32: Park/Neutral Position (PNP) Switch Signal

NOTE: Code is set if TCU does not receive any signal from PNP or receives 2 or more signals simultaneously.
  1. Turn ignition on. Disconnect PNP harness connector. Using DVOM, measure voltage between harness connector terminal No. 7 and ground, and terminal No. 8 and ground. If battery voltage is not present, inspect No. 16 (BACK) fuse under dash. Replace as needed.
  2. If fuse is okay, inspect and repair power supply circuits between PNP switch and fuse. Refer to the appropriate wiring diagram in WIRING DIAGRAMS  .
  3. Turn ignition off. Disconnect TCU harness connector. See Figure . Inspect continuity of each circuit between TCU and PNP switch. See Figure and Fig 1 . Repair as needed. Ensure there is no short to ground in any circuit tested. If PNP switch is suspected, see PARK/NEUTRAL POSITION (PNP) SWITCH  under COMPONENT TESTING.
