What Does U0107 Mean?
The powertrain control module cannot communicate with the electronic throttle actuator control module. This affects engine power control and throttle response.
Safety Warning
Engine may enter limp mode with reduced power, or fail to respond to accelerator pedal. Critical safety issue if throttle becomes unresponsive in traffic.
Common Causes
35%
Damaged wiring or corroded connectors to throttle actuator module
30%
Failed throttle actuator control module or throttle body assembly
20%
CAN bus network failure or short circuit
10%
Power or ground circuit failure to throttle actuator
5%
Module calibration error or software corruption
Diagnostic Steps
1
Step 1: Verify power and ground to electronic throttle body using multimeter
2
Step 2: Inspect throttle body connector and wiring for damage, corrosion, or loose connections
3
Step 3: Check CAN bus communication signals at throttle body connector
4
Step 4: Perform throttle body relearn procedure per manufacturer specifications
5
Step 5: Test throttle actuator motor operation or replace throttle body assembly if circuits are good
Estimated Repair Cost
$200 - $1,000
Parts + labor, varies by vehicle and location
The powertrain control module cannot communicate with the electronic throttle actuator control module. This affects engine power control and throttle response.
The most common cause of U0107 (Lost Communication With Throttle Actuator Control Module) is: Damaged wiring or corroded connectors to throttle actuator module
Typical repair costs for U0107 range from $200 to $1,000, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Engine may enter limp mode with reduced power, or fail to respond to accelerator pedal. Critical safety issue if throttle becomes unresponsive in traffic.
