DTC P1706/6: A/T Gear Position Switch (Open)

WARNING: This page is about a different car, the 1998 Honda Odyssey, 1998 Honda Accord, and 1998 Acura 2.3CL. However, it is still accessible from the selected car via links, so may be relevant.
  1. Test A/T gear position switch. See A/T GEAR POSITION INDICATOR  under SYSTEM TESTING. If switch is okay, go to next step. If switch fails test, replace A/T gear position switch.
  2. Shift to Reverse. Using a DVOM, measure voltage 16-pin PCM harness connector "D", terminal No. 6 (Green/Red wire on 2.3CL or White wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). See Figure and Figure . If voltage is not present, go to next step. If voltage is present, repair open in Green/Red or White wire between 16-pin PCM harness connector "D" and A/T gear position switch.
  3. Shift to Neutral or Park. Measure voltage between 16-pin PCM harness connector "D", terminal No. 13 (Blue/White wire on Accord or Light Green wire on 2.3CL and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If voltage is not present, go to next step. If voltage is present, repair open in Blue/White or Light Green wire between 16-pin PCM harness connector "D" and A/T gear position indicator.
  4. Shift to "D4" position. Measure voltage between 16-pin PCM harness connector "D", terminal No. 9 (Light Green/Black wire on 2.3CL or Yellow wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If voltage is not present, go to next step. If voltage is present, repair open in Light Green/Black or Yellow wire between 16-pin PCM harness connector "D" and A/T gear position switch.
  5. Shift to "D3" position. Measure voltage between 16-pin PCM harness connector "D", terminal No. 8 (Green/Blue wire on 2.3CL or Pink wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If voltage is not present, go to next step. If voltage is present, repair open in Green/Blue or Pink wire between 16-pin PCM harness connector "D" and A/T gear position switch.
  6. Shift to "2" position. Measure voltage between 16-pin PCM harness connector "D", terminal No. 14 (Green/Yellow wire on 2.3CL or Blue wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If voltage is not present, go to next step. If voltage is present, repair open in Green/Yellow or Blue wire between 16-pin PCM harness connector "D" and A/T gear position switch.
  7. Shift to "1" position. Measure voltage between 16-pin PCM harness connector "D", terminal No. 15 (Light Green/White wire on 2.3CL or Brown wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If voltage is not present, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary. If voltage is present, repair open in Light Green/White or Brown wire between 16-pin PCM harness connector "D" and A/T gear position switch.
