EGR valve
Be sure to perform installation assessment as specified by Yanmar to ensure applicability of the EGR valve
to the intended machine.
Do not expose the EGR valve motor to an ambient temperature exceeding 80°C.
Accelerator sensor
Connect the accelerator sensor according the recommended connection diagram. Make sure the
accelerator sensor and the E-ECU have a common reference potential (GND potential) as shown in example
[A] of
If the E-ECU is connected to a machine controller as shown in example [B] or [C], the
difference between the E-ECU and the machine comptroller in reference potential (V1
≠
V2) may cause
excess voltage to be applied to the APS input of the E-ECU or excess current to flow through GND-A.

Accelerator sensor connection examples
Read
carefully before utilizing a Yanmar genuine accelerator sensor in order to
ensure correct use of the sensor.
Be sure to perform installation assessment as specified by Yanmar to ensure applicability of the accelerator
sensor to the intended machine.
