DTC P1410 - Fuel Tank Pressure Control System Malfunction
- Turn ignition on. Using a voltmeter, measure voltage (backprobe) between ground and PCM harness connector "A", terminal No. 19. If reading is 0.8 volt or greater, check for an intermittent problem. See TESTS W/O CODES article. If reading is not as specified, go to next step.
- Turn ignition off. Disconnect harness connector from tank pressure control solenoid vacuum valve. Using an ohmmeter, measure resistance between terminals of solenoid. Resistance should be 33-39 ohms at 68°F (20°C). Resistance between each terminal and body of solenoid should be one megohm or greater. If resistance is as specified, go to next step. If resistance is not as specified, replace tank pressure control solenoid vacuum valve. Retest system.
