Auto Repairing 1998–2002 Honda Accords Troubleshooting A/T DTCs P0753, P0758, P1705, P1768
On ’98–02 Accords with A/T and ’99–02 Odysseys, if the PGM-FI main relay sticks after you turn the ignition switch to LOCK (0), the PCM will repeatedly set these A/T DTCs: • P0753 (shift solenoid valve A) • P0758 (shift solenoid valve B) • P1705 (transmission range switch short to ground) • P1768 (A/T clutch pressure control solenoid valve A) To check for a sticking PGM-FI main relay, do this: 1. Connect your PGM Tester to the 16P data link connector (DLC). 2. Turn the ignition switch to LOCK (0), and watch the PGM Tester display screen: • If you see the NO COMMUNICATION message as soon as you turn the switch to LOCK (0), the main relay is OK. Continue with normal troubleshooting. • If you don’t see the NO COMMUNICATION message, the PCM is still getting 12 volts, which is most likely being supplied by a faulty main relay. Replace the main relay.
