What Does P2113 Mean?
The PCM has detected that throttle or pedal position sensor B is not reading the expected minimum voltage or position when the throttle should be fully closed. This indicates a sensor calibration, reference voltage, or hardware issue.
Common Causes
35%
Faulty throttle position sensor B circuit or internal sensor failure
30%
Accelerator pedal position sensor B malfunction or misadjustment
20%
Wiring issues including short to voltage, open circuit, or high resistance in sensor B circuit
10%
Reference voltage supply fault from PCM or ground circuit problem
5%
Throttle body requiring relearn procedure or calibration after service
Diagnostic Steps
1
Step 1: Monitor throttle position sensor B voltage/percentage at idle with scan tool; should read approximately 0.5-1.0V or manufacturer specification
2
Step 2: Check accelerator pedal position sensor B signal at rest position; verify it matches expected minimum value
3
Step 3: Backprobe sensor B signal wire and verify 5V reference voltage and good ground at sensor connector
4
Step 4: Wiggle test wiring harness while monitoring sensor data for intermittent dropouts or spikes
5
Step 5: Replace faulty sensor (throttle body or pedal assembly) if voltage is out of range and wiring/reference voltage is correct
Estimated Repair Cost
$100 - $700
Parts + labor, varies by vehicle and location
The PCM has detected that throttle or pedal position sensor B is not reading the expected minimum voltage or position when the throttle should be fully closed. This indicates a sensor calibration, reference voltage, or hardware issue.
The most common cause of P2113 (Throttle/Pedal Position Sensor "B" Minimum Stop Performance) is: Faulty throttle position sensor B circuit or internal sensor failure
Typical repair costs for P2113 range from $100 to $700, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle may enter reduced power mode limiting acceleration. Inconsistent throttle response may occur, affecting drivability and potentially causing unexpected power delivery.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2113 to identify the root cause.
