SOURCE: What do you need help with?fault code p1215 on noah 1az engine

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 ECU.

Possible causes:

- Faulty EDU - EDU harness is open or shorted - EDU circuit poor electrical connection - Faulty Spill control valve

Hope this helps.

Toyota Noah 1az-fse motor. I was driving and it cut out. I then diagnosed the vehicle and it came up with throttle/pedal sensors a circuit and inlet manifold barometric pressure sensor circuit.


have they tried clearing the faults an re calibrate the throttle body
if that's been done replace the sensor
for now wouldn't worry to much about the manifold sensor cause that can be because of the throttle fault

In stead of changing what is not wrong, save money and time by having the fault codes read and fixing the fault
check engine lights refer to both an engine problem and a transmission problem so what you may have could be in the transmission.
