DTC P1410: Fuel Tank Pressure Control System Malfunction
- Turn ignition on. Measure voltage (backprobe) between ground and PCM harness connector "A" terminal No. 16 (Blue/White wire). If reading is 10 volts or more, problem is intermittent or due to a faulty PCM. If reading is less than 10 volts, go to next step.
- Turn ignition off. Disconnect Tank Pressure Control Solenoid Valve (TPCSV) harness connector. Measure resistance between TPCSV terminals. Resistance should be 33-39 ohms at 68°F (20°C). If resistance is as specified, go to next step. If resistance is not as specified, replace TPCSV.
- Measure resistance between both terminals of TPCSV and TPCSV body. Resistance should be 1 megohm or higher. If resistance is not as specified, replace TPCSV. If resistance is as specified, check Red/Black wire and Blue/White wire for an open or short. If connectors and wiring are okay, replace PCM.
