P0401 TOYOTA - Exhaust Gas Recirculation Flow Insufficient Detected...Possible causes; EGR passage clogged, Faulty EGR Vacuum Modulator Valve, Faulty EGR Valve, Faulty EGR solenoid valve, EGR solenoid valve harness is open or shorted, EGR solenoid valve circuit poor electrical connection, Dead (Weak) battery, Faulty EGR temperature sensor and circuit, Exhaust gas leaks...EGR flow malfunction could be caused by a clogged EGR valve or EGR tube. Before replacing any parts try cleaning the EGR valve, tube and passages.

Remove the vacuum hose from the EGR valve. Using a hand held vacuum pump apply vacuum to the EGR valve with the engine running at idle. The engine SHOULD stall. If not, either the EGR valve is not opening or the EGR passages are clogged. HTH. -Jim
