Check / Manual Mode / AIR PUMP 1: ON, ASV 1: OPEN, AIR PUMP 2: ON, ASV 2: OPEN.
HINT:
When Manual Mode is selected, the Techstream initialization (atmospheric pressure measurement) is
performed automatically. The initialization takes 10 seconds. After the initialization, AIR PUMP and ASV
operation can be selected.
(n) Start the engine.
(o) Perform the AIR system forced operation while the engine is idling.
(q) Turn the ignition switch off.

Circuit Low; 2015 MY Tundra [08/2014 - ]
DTC
P2102
Throttle Actuator Control Motor Circuit Low
DTC
P2103
Throttle Actuator Control Motor Circuit High
DESCRIPTION
The throttle actuator is operated by the ECM and opens and closes the throttle valve using gears.
control the throttle actuator and monitor the throttle opening angle as the ECM responds to driver inputs.
HINT:
This ETCS (Electronic Throttle Control System) does not use a throttle cable.
DTC
NO.
DTC DETECTION CONDITION
TROUBLE AREA
P2102
Conditions (a) and (b) continue for 2.0 seconds (1 trip
detection logic):
(a) Throttle actuator duty ratio 80% or more
(b) Throttle actuator current less than 0.5 A
Open in throttle actuator

ECM
MONITOR DESCRIPTION
The ECM monitors the electrical current through the electronic actuator, and detects malfunctions and open
circuits in the throttle actuator based on this value. If the current is outside the standard range, the ECM
determines that there is a malfunction in the throttle actuator. In addition, if the throttle valve does not
function properly (for example, stuck on), the ECM determines that there is a malfunction. The ECM then
illuminates the MIL and stores a DTC.
Example:
When the electrical current is less than 0.5 A and the throttle actuator duty ratio exceeds 80%, the ECM
interprets this as the current being outside the standard range, and illuminates the MIL and sets a DTC.
If the malfunction is not repaired successfully, a DTC is set when the engine is quickly revved to a high rpm
several times after the engine is started and has idled for 5 seconds.
