CHECK ENGINE WARNING LIGHT CIRCUIT
CIRCUIT DESCRIPTION
The CHK ENG is used to indicate the ECM’s detection of a vehicle malfunction.
The instrument panel IGN fuse provides the circuit power and the ECM provides the circuit ground that illumi-
nates the CHK ENG.
CHK ENG operations should be checked visually:
The CHK ENG should be illuminated when the ignition is first turned to ON. If the CHK ENG is always ON
or OFF, use the hand−held tester and follow the procedures below to determine the cause of the problem.

INSPECTION PROCEDURE
HINT:
Troubleshoot each trouble symptom in accordance with the chart below.

DTC P2118 THROTTLE ACTUATOR CONTROL MOTOR
CURRENT RANGE/PERFORMANCE
CIRCUIT DESCRIPTION
The Electronic Throttle Control System (ETCS) has a dedicated power supply circuit. The voltage (+BM) is
monitored and when the voltage is low (less than 4V), the ECM concludes that the ETCS has a fault and
current to the throttle control motor is cut.
When the voltage becomes unstable, the ETCS itself becomes unstable. For this reason, when the voltage
is low, the current to the motor is cut. If repairs are made and the system has returned to normal, turn the
ignition switch to OFF. The ECM then allows current to flow to the motor and the motor can be restarted.
HINT:
This Electrical Throttle Control System (ETCS) does not use a throttle cable.
