P2119

Critical
Moderate

Throttle Actuator Control Throttle Body Range/Performance

What Does P2119 Mean?

The PCM has detected that the actual throttle plate position does not match the commanded position, indicating a performance issue with the electronic throttle body assembly. This suggests mechanical or electrical problems preventing proper throttle control.

Safety Warning

Vehicle will likely enter limp mode with severely limited power and throttle response. May cause unexpected acceleration behavior. Do not drive; tow to repair facility.

Diagnostic Steps

1

Step 1: Perform throttle body visual inspection for carbon deposits, debris, or physical damage

2

Step 2: Use scan tool to monitor commanded vs. actual throttle position in real-time during key-on engine-off test

3

Step 3: Clean throttle body thoroughly using appropriate cleaner; check for smooth operation after cleaning

4

Step 4: Perform throttle relearn/adaptation procedure per manufacturer specifications

5

Step 5: If issue persists, test throttle actuator motor operation using bidirectional controls and replace throttle body if faulty

Estimated Repair Cost

$100 - $750
