DTC P0705: Transmission Range (Tr) Switch Circuit

NOTE: DTC is set if PCM does not receive any signal from TR switch, or receives 2 or more signals simultaneously. TR switch may also be known as Park/Neutral Position (PNP) switch.
  1. Turn ignition switch to LOCK position. Disconnect PCM 22-pin harness connector, located under instrument panel, behind glove box. Turn ignition on. Using a DVOM, measure voltage between chassis ground and PCM 22-pin harness connector terminal No. 15 (Green/Red wire). See Fig 1. Monitor voltage while moving gear selector through all gear ranges. If reading is 12 volts in "D" range, and less than one volt in any other gear range, go to next step. If reading is not as specified, go to step  8.
  2. Using a DVOM, measure voltage between chassis ground and PCM 22-pin harness connector terminal No. 14 (Green/Blue wire). See Fig 1. Monitor voltage while moving gear selector through all gear ranges. If reading is 12 volts in "L" range, and less than one volt in any other gear range, go to next step. If reading is not as specified, go to step  12.
  3. Using a DVOM, measure voltage between chassis ground and PCM 22-pin harness connector terminal No. 4 (Orange/Yellow wire). See Fig 1.

  11. Using a DVOM, measure voltage between chassis ground and TR switch harness connector terminal No. 8 (Yellow wire). See Fig 2. If reading is 11-14 volts, check for proper TR switch adjustment. See ADJUSTMENTS in appropriate AUTOMATIC TRANSMISSION SERVICING article in TRANSMISSION SERVICING. If adjustment is okay, replace TR switch. If reading is not as specified, repair Yellow wire for an open or high resistance.
  12. Turn ignition switch to LOCK position. Disconnect TR switch harness connector. Turn ignition on. Using a DVOM, measure voltage between chassis ground and PCM 22-pin harness connector terminal No. 14 (Green/Blue wire). See Fig 1. If reading is one volt or less, go to next step.
