What Does P2115 Mean?
The PCM has detected that throttle or pedal position sensor D is not reading the expected minimum stop position value. This affects the redundancy and accuracy of the electronic throttle control system.
Common Causes
35%
Throttle position sensor D internal failure or circuit malfunction
30%
Accelerator pedal position sensor D fault or calibration error
20%
Wiring harness damage, connector pin corrosion, or terminal tension loss in sensor D circuit
10%
PCM voltage supply issue or internal circuit fault affecting sensor D
5%
Physical obstruction or mechanical binding affecting sensor reading
Diagnostic Steps
1
Step 1: Compare sensor D minimum position reading to manufacturer specifications using scan tool at closed throttle
2
Step 2: Test reference voltage and ground at sensor D connector; should have stable 5V supply
3
Step 3: Check sensor D signal wire for short to voltage, short to ground, or high resistance
4
Step 4: Monitor all position sensors simultaneously to identify correlation issues between redundant sensors
5
Step 5: Replace affected component (throttle body or pedal sensor) if sensor D voltage is incorrect with verified good power/ground
Estimated Repair Cost
$100 - $700
Parts + labor, varies by vehicle and location
The PCM has detected that throttle or pedal position sensor D is not reading the expected minimum stop position value. This affects the redundancy and accuracy of the electronic throttle control system.
The most common cause of P2115 (Throttle/Pedal Position Sensor "D" Minimum Stop Performance) is: Throttle position sensor D internal failure or circuit malfunction
Typical repair costs for P2115 range from $100 to $700, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Engine may enter limp mode with reduced power output. Loss of sensor redundancy may lead to unpredictable throttle behavior if additional sensors fail.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2115 to identify the root cause.
