What Does P2114 Mean?
The PCM has detected that throttle or pedal position sensor C is not achieving the expected minimum stop position signal. This redundant sensor failure compromises the system's ability to verify accurate throttle position.
Common Causes
35%
Failed throttle position sensor C circuit within throttle body assembly
30%
Accelerator pedal position sensor C circuit fault or sensor degradation
20%
Damaged wiring, corroded connectors, or poor ground connection in sensor C circuit
10%
PCM reference voltage issue affecting sensor C power supply
5%
Contamination or mechanical issue preventing proper sensor reading
Diagnostic Steps
1
Step 1: Monitor sensor C voltage/position data at closed throttle with scan tool and compare to specifications
2
Step 2: Verify proper reference voltage (typically 5V) at sensor C connector with DVOM
3
Step 3: Check sensor C ground circuit continuity and resistance to battery negative
4
Step 4: Perform voltage sweep test by slowly depressing accelerator pedal while monitoring all sensor circuits for correlation
5
Step 5: Replace throttle body or pedal position sensor assembly if sensor C shows incorrect minimum voltage with proper reference/ground
Estimated Repair Cost
$100 - $700
Parts + labor, varies by vehicle and location
The PCM has detected that throttle or pedal position sensor C is not achieving the expected minimum stop position signal. This redundant sensor failure compromises the system's ability to verify accurate throttle position.
The most common cause of P2114 (Throttle/Pedal Position Sensor "C" Minimum Stop Performance) is: Failed throttle position sensor C circuit within throttle body assembly
Typical repair costs for P2114 range from $100 to $700, depending on the vehicle, location, and whether you do it yourself or go to a shop.
PCM may limit engine power due to loss of redundant sensor verification. Inconsistent throttle response poses risk of unexpected acceleration or deceleration.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2114 to identify the root cause.
