Code P1215 Toyota Description

The Electronic Driving Unit (EDU) drives the spill control valve at high speeds. The EDUs high speed driving under high fuel pressure conditions is achieved through the use of a DC/DC converter that provides a high voltage, quick charging system.
The engine Electronic Control Unit (ECU) constantly monitors the EDU and stops the engine in case an abnormal condition is detected.
The battery voltage is increased by the DC/DC converter. A voltage of approximately 50 V is applied to the spill control valve in accordance with the IJ+ signal received from the engine ECU. At this time, the injection verification signal (IJF) is sent to the engine ECU.
