DTC P0705 - Park/Neutral Position Switch

1. Check Power Circuit
   
   Turn ignition off. Disconnect park/neutral position switch wiring harness connector. See Fig 1. Turn ignition on. Measure voltage between park/neutral position switch connector terminal "3" (Black wire) and body ground. See Fig 2. If battery voltage is present, go to next step. If battery voltage is not present, repair harness or connectors as necessary.
2. Check Input Signal Circuit
   
   Turn ignition off. Disconnect A/T control unit wiring harness connector. Check continuity between park/neutral position switch connector terminals No. "7" (Brown wire) and No. "9" (Black/Red wire) and A/T control unit terminal No. 19. If continuity is not present, repair harness or connectors as necessary.
3. Check Component
   
   Ensure park/neutral position switch is not damaged or contaminated. Check park/neutral position switch and ECM harness connectors for damage, corrosion or pushed-out pins. Repair if necessary. If no problems are found, replace park/neutral position switch.
