Introduction to the engine control system
The engine temperature sensor is mounted on the left hand side of the vertical cylinder.
Location of engine temperature sensor connector.
Wiring diagram
CCM engine control connection, S engine temperature sensor. 1 green/white – G/W, 2 black/purple – Bk/V.
In the event of fault
In the event of an engine temperature sensor fault, the engine control unit implements a recovery value of 70°C and
activates the radiator fans.
Fault codes generated and possible correlated faults
Fault codes generated by the engine control unit and displayed by the DDS (Engine temperature sensor diagnosis):
- Short circuit to Vdc: check integrity of electric circuit, check integrity of electrical connections
- Short circuit to ground: check integrity of electric circuit, check integrity of electrical connections
- Open circuit: check integrity of electric circuit, check integrity of electrical connections
Note
Check integrity of electric circuit – short-circuit to Vdc = with dashboard on, using a voltmeter, a voltage is measured
between the wire tested and ground.
Check integrity of electric circuit – short-circuit to ground = with the battery cables disconnected, using an ohmmeter,
continuity is detected between the wire tested and ground.
Check integrity of electric circuit – open circuit = with the battery cables disconnected, using an ohmmeter, no continuity
is detected between the two ends of the wire tested.
The tank dashboard shows the error "Engine temperature" and the EOBD warning light activates.
When the dashboard receives the "Engine temperature" error, flashing dashes are displayed instead of the temperature
reading. If the dashboard does not receive engine temperature information from the CAN line, the error "Engine
temperature" is not shown on the display, but flashing dashes are still displayed instead of the temperature reading.
