2.
INSPECT THROTTLE WITH MOTOR BODY ASSEMBLY (VISUALLY CHECK THROTTLE
VALVE)
(a) Check for contamination between the throttle valve and housing. If necessary, clean the throttle with
motor body assembly. Also, check that the throttle valve moves smoothly.
OK:
Throttle valve is not contaminated with foreign objects and moves smoothly.

Performance; 2015 MY Tundra [08/2014 - ]
DTC
P2118
Throttle Actuator Control Motor Current Range / Performance
DESCRIPTION
The ETCS (Electronic Throttle Control System) has a dedicated power supply circuit. The voltage (+BM) is
monitored and when it is low (less than 4 V), the ECM determines that there is a malfunction in the ETCS and
cuts off the current to the throttle actuator.
When the voltage becomes unstable, the ETCS itself becomes unstable. For this reason, when the voltage is low,
the current to the throttle actuator is cut. If repairs are made and the system returns to normal, turn the ignition
switch off. The ECM then allows the current to flow to the throttle actuator so that it can be restarted.
HINT:
The ETCS does not use a throttle cable.
DTC NO.
