Engine Coolant Temperature Circuit Malfunction (P0115,P0117,P0118)
DESCRIPTION
A thermistor, whose resistance value varies according to the engine coolant temperature,
is built into the engine coolant temperature sensor.
The structure of the sensor and its connection to the ECM are similar to those
of the intake air tem ...
Tachometer Malfunction
DESCRIPTION
In this circuit, the meter CPU receives engine speed signals from the ECM using
the CAN communication system (CAN No. 1 Bus). The meter CPU displays the engine
speed calculated based on the data received from the ECM.
