DTC Troubleshooting: P0705 (5-2)

DTC P0705:  Short in Transmission Range Switch Circuit (Multiple Shift-position Input)


NOTE:

1.Clear the DTC in CLEAR MENU with the Honda PGM Tester or HDS.

2.Move the shift lever to each position slowly, and check the OBD STATUS in DTCs MENU for a pass/fail test of code P0705.

Did the result fail?


YES - Go to 3.


NO - Intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETE, return to step 1 and recheck.n


3.Inspect the transmission range switch.

Is the switch OK?


YES - Go to 4.


NO - Replace the  transmission range switch. Recheck for a pass/fail test of code P0705 by performing step 1 and 2 after replacing the switch. If the test result is failed, recheck the  transmission range switch.n

4.Shift to all positions other than [P].

5.Measure the voltage between PCM connector terminals D6 and A8 or A9.

Is there battery voltage?


YES - Go to 6.


NO - Check for a short in the wire between PCM connector terminal D6 and the transmission range switch, and check for an open in the wires between ground G101 and PCM connector terminals A8 and A9. If the wires are OK, update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.n

6.Shift to all positions other than [R].

7.Measure the voltage between PCM connector terminals D5 and A8 or A9.
