Inspection Procedure: P0340; Inspect The Engine Speed Sub Sensor Connector; Inspect The Engine Speed Sub Sensor (Camshaft Position Sensor) - Hino Motors HINO 155 series Workshop Manual

2–450

INSPECTION PROCEDURE: P0340

1
Inspect the engine speed sub sensor (camshaft position sensor) connector
Was any failure found?
Connect securely, repair if needed.
Perform "After-inspection work" of INFOR-
MATION section.
2

Inspect the engine speed sub sensor (camshaft position sensor)

Was any failure found?
Clean the sensing unit and install it properly.
If damaged, replace the engine speed sub
sensor (camshaft position sensor).
If there is corrosion on the sensor mounting
surface, polish the mounting surface or
replace the cylinder head.
Perform "After-inspection work" of INFOR-
MATION section.
ENGINE (J05E)/TROUBLESHOOTING
1. Check the connection of the engine speed sub sensor (camshaft
position sensor) connector (looseness and poor contact).
YES
1. Check the installation of the engine speed sub sensor (camshaft
position sensor).
• Check that there are no loose mounting bolts.
• Check that the sensor is installed so that it is pushed to the root with-
out gap with the sensor flange mounting surface.
• Check that they are not mounted diagonally.
HINT
In case of foreign matter and corrosion on the sensor mounting
surface, the gap between the cam shaft gear and sensor may
become inaccurate, and error may occur without any pulse signal
from the sensor. In such case, please inspect the mounting sur-
face.
2. Make sure there is no dirt, damage or clogging in the sensing unit
of the engine speed sub sensor (camshaft position sensor).
YES
NO
Go to step 2.
NO
Go to step 3.
