1A-155 Engine General Information and Diagnosis:
Circuit/System Testing
1. Ignition OFF, remove the fuse that supplies voltage
to terminals C2-3, C2-5, and C2-6 of the ECM. Verify
the fuse is OK.
NOTE
This DTC will only set if the fuse is open and
the circuits are not grounded. The ignition
voltage circuits must be tested thoroughly
for an intermittent short to ground.
➢ If the fuse is open, test the ignition voltage circuit
between the open fuse and the ECM for an
intermittent short to ground.
2. Install the fuse.
3. Disconnect the harness connector of the ECM.
Ignition ON, load test for battery voltage on the
ignition circuits at the ECM.
➢ If less than B+, repair the ignition circuit for an
open/high resistance.
4. If all circuits/connections test OK, replace the ECM.

DTC Descriptors
DTC P2107: Throttle Actuator Control (TAC) Module
Internal Circuit
Circuit/System Description
The engine control module (ECM) controls the throttle
valve by applying a varying voltage to the throttle
actuator control motor. The ECM monitors the actual
throttle valve position using throttle position (TP) sensor
1 and 2. The ECM amplifies the TP sensor 1 signal in
order to obtain a more accurate signal. The ECM
monitors the TP sensor 1 amplification output whenever
the ignition is ON and a closed throttle test is performed.
Conditions for Running the DTC
• The vehicle speed is 0 km/h (0 mph).
• The engine speed is less than 40 RPM.
• The engine coolant temperature (ECT) is 5-85°C (41-
185°F).
• The intake air temperature (IAT) is 5-60°C (41-140°F).
• The ignition voltage is more than 10 volts.
• The accelerator pedal position (APP) is less than 15
percent.
• The ECM is performing the closed throttle test with the
ignition ON and the engine OFF.
• DTC P2107 runs once the above conditions are met
during the throttle actuator control system
initialization.
Conditions for Setting the DTC
The ECM detects the internal TP sensor 1 amplification
output does not correlate with the TP sensor 1 signal
voltage for more than 4 seconds.
Action Taken When the DTC Sets
DTC P2107 is a Type C DTC.
Conditions for Clearing the DTC
DTC P2107 is a Type C DTC.
Circuit/System Verification
1. Ignition ON, observe the DTC information with a
scan tool for 30 seconds. DTC P2107 should not set.
➢ If DTC P2107 sets, replace the ECM.
2. If the vehicle passes the Circuit/System Verification
Test, then operate the vehicle within the conditions
for running the DTC. You may also operate the
vehicle within the conditions that are captured in the
Freeze Frame/Failure Records List.
