What Does P2116 Mean?
The PCM has detected that throttle or pedal position sensor E is not achieving the expected minimum stop performance specification. This represents a fault in one of the redundant position sensor circuits.
Common Causes
35%
Throttle body position sensor E circuit failure or sensor degradation
30%
Accelerator pedal position sensor E malfunction or internal short
20%
Corroded connectors, damaged wiring, or poor pin contact in sensor E circuit
10%
PCM power supply fault or internal processing error affecting sensor E
5%
Carbon buildup or mechanical issue affecting sensor calibration point
Diagnostic Steps
1
Step 1: Verify sensor E minimum voltage reading with scan tool at rest position; compare to specifications
2
Step 2: Backprobe sensor E connector and measure reference voltage, signal voltage, and ground quality with DVOM
3
Step 3: Inspect connector terminals for corrosion, bent pins, or moisture intrusion
4
Step 4: Perform rationality check by comparing sensor E readings against other position sensors through pedal sweep
5
Step 5: Replace throttle body or pedal position sensor if sensor E fails to meet minimum stop specifications with good wiring
Estimated Repair Cost
$100 - $700
Parts + labor, varies by vehicle and location
The PCM has detected that throttle or pedal position sensor E is not achieving the expected minimum stop performance specification. This represents a fault in one of the redundant position sensor circuits.
The most common cause of P2116 (Throttle/Pedal Position Sensor "E" Minimum Stop Performance) is: Throttle body position sensor E circuit failure or sensor degradation
Typical repair costs for P2116 range from $100 to $700, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Vehicle may experience reduced power mode activation. Loss of redundant sensor data may result in inconsistent throttle response and difficulty maintaining steady speed.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P2116 to identify the root cause.
