- Faulty EDU - EDU harness is open or shorted - EDU circuit poor electrical connection - Faulty Spill control valve What does this mean? Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) P1215 Description The 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 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

That is how you find your OBD Codes

OBD & your code

OBD P1215

The automatic idle valve may need cleaning or the control module that operates it may be bad.

p1215 is the educational circuit Injectors That ControlA Peaks is in the engine compartment and has 8 pin module is not Working with the ecu you got That review also That relay is in the circuit. on this page I hope you got the diagram to help you
