P2113 — Throttle/Pedal Position Sensor “B” Minimum Stop Performance #

Note: The wording of this trouble code may differ depending on the vehicle manufacturer. Always refer to your OEM (Original Equipment Manufacturer) service documentation for the exact description.

• Throttle/Pedal Position Sensor “B” Minimum Stop Performance (Generic/Multiple OEMs)
• Throttle Actuator Control (TAC) System – Throttle Position Sensor “B” Minimum Stop Performance (Ford/Lincoln/Mercury)
• Electronic Throttle Control: Throttle Position Sensor “B” Minimum Stop (Toyota/Lexus/Scion)
• Accelerator Pedal Position Sensor “B” Minimum Stop Performance (Nissan/Infiniti)

Summary of Code P2113 #

Diagnostic Trouble Code (DTC) P2113 indicates that the Powertrain Control Module (PCM) or Engine Control Module (ECM) has detected a problem with the minimum stop performance of the Throttle/Pedal Position Sensor “B”. This sensor monitors the position of the throttle or accelerator pedal, ensuring the electronic throttle body operates within set parameters. When the sensor’s minimum value does not match the expected reference, the PCM/ECM sets the P2113 code. This fault can lead to issues in throttle response and may trigger the vehicle’s “limp” mode to protect the engine and transmission. Prompt attention to this code is recommended to avoid drivability problems or potential safety concerns.

Common Symptoms for Code P2113 #

When P2113 is present, you may notice a range of performance issues related to the vehicle’s throttle control. Since the sensor is critical for communicating driver input to the engine, any misreading can cause noticeable symptoms. Typical signs include:

• Check Engine Light illuminated
• Reduced engine power or “limp” mode activation
• Poor throttle response or hesitation when accelerating
• Unstable or fluctuating idle speed
• Difficulty accelerating or lack of power
• Unusual throttle behavior, such as delayed or erratic response

Likely Causes for Code P2113 #

P2113 can be caused by several issues, most of which relate directly to the throttle or pedal position sensor and their associated components. Here are the most common culprits, ranked by likelihood:

1. Faulty Throttle/Pedal Position Sensor “B” (internal failure, contamination, or wear)
2. Throttle body assembly malfunction (especially in vehicles using electronic throttle bodies)
3. Wiring issues (damaged, shorted, or corroded harnesses and connectors)
4. PCM/ECM software glitches or failure
5. Physical obstruction or carbon buildup preventing throttle plate from closing fully
6. Incorrect installation or adjustment of the throttle body or sensors (after service or replacement)

Step-by-Step Diagnosis for Code P2113 #

A thorough, methodical approach will help you pinpoint the root cause of P2113. Take your time and avoid skipping steps, as misdiagnosis can lead to unnecessary part replacement.

1. Connect a scan tool to confirm P2113 and check for related codes (especially P2111–P2119 or sensor-specific codes).
2. Visually inspect the throttle body, accelerator pedal assembly, and wiring harness for damage, contamination, or loose connections.
3. Check sensor readings for Throttle/Pedal Position Sensor “B” at rest and during slow pedal movement using live data on your scan tool. Compare with “A” sensor if available.
4. Test the sensor voltage at the connector with a digital multimeter. Look for expected values; typically, a minimum stop value at rest near OEM specs (often around 0.5V, but consult your OEM manual).
5. Inspect throttle plate for carbon buildup or sticking. Manually move the plate (engine off) to ensure free movement.
6. If wiring and sensor test normal, check for PCM/ECM updates or known technical service bulletins (TSBs) related to P2113 for your vehicle.
7. If all else fails, substitute with a known-good throttle body or sensor to confirm diagnosis before replacing expensive components.

Possible Repairs for Code P2113 #

Once you’ve identified the root cause, select the appropriate repair to restore throttle system function and clear the DTC. Always clear the code and perform a test drive after repairs.

• Replace the Throttle/Pedal Position Sensor “B” if it fails testing or shows erratic signals
• Clean or replace the throttle body assembly if carbon buildup or mechanical sticking is present
• Repair or replace damaged wiring/connectors between the sensor, throttle body, and PCM/ECM
• Update or reprogram the PCM/ECM if a software issue or TSB applies
• Reinstall or recalibrate throttle components if incorrectly installed after previous service

Is It Safe to Drive with Code P2113? #

Driving with P2113 is generally not recommended, especially if the vehicle has entered “limp” mode or is experiencing significant throttle response issues. Loss of power or erratic throttle function can create unsafe driving conditions, particularly in heavy traffic or on highways. If you must drive, do so only short distances and seek professional diagnosis and repair as soon as possible.

Vehicles Commonly Affected by Code P2113 #

While P2113 is a generic OBD-II code, it is more frequently reported on certain makes and models, especially those with electronic throttle control systems from the mid-2000s onward. The following vehicles have shown higher occurrence rates:

• Ford (Fusion, F-150, Escape, Focus, Explorer)
• Toyota (Camry, Corolla, RAV4, Tacoma, Prius)
• Nissan (Altima, Maxima, Sentra, Rogue)
• Mazda (Mazda3, Mazda6, CX-5, Tribute)
• Lexus (ES, RX, IS series)
• Infiniti (G35, FX35, QX60)
• General Motors (Chevrolet Malibu, Equinox, Silverado)

Remember, the code can appear on nearly any OBD-II compliant vehicle equipped with electronic throttle control.

Common Mistakes & Best Practices for Code P2113 #

Quick fixes or assumptions often lead to frustration and wasted money. Here are the most common pitfalls and tips to ensure a successful repair:

• Replacing the throttle body or sensor without verifying wiring and connections first
• Ignoring Technical Service Bulletins (TSBs) or software updates from the OEM
• Cleaning the throttle body without recalibrating the throttle position with a scan tool (if required by OEM)
• Overlooking intermittent wiring faults—wiggle test harness during diagnosis
• Skipping live data analysis—comparing sensor “A” and “B” signals helps pinpoint the faulty component

Quick FAQ for Code P2113 #

To wrap up, here are answers to some of the most common questions drivers and technicians ask about P2113:

• Q: Can I clear the code and see if it comes back?
  A: You can, but if the underlying issue isn’t fixed, the code will likely return quickly. Always address the root cause.
• Q: Does P2113 mean I need a new throttle body?
  A: Not always. Sometimes the sensor can be replaced separately, or the problem lies in wiring, calibration, or even software. Diagnose before replacing parts.
• Q: Will my car fail inspection with this code?
  A: Yes, an active check engine light and stored DTC P2113 will cause most OBD-II emissions tests to fail.
