P2113 code definition
P2113 is a general OBD-II diagnostic trouble code indicating a malfunction with the throttle/pedal position sensor “B” minimum stop performance. This code may be seen with other throttle body or pedal position codes.
What the P2113 code means
The throttle/pedal position sensor “B” is used along with other sensors to communicate to the engine control module (ECM) what the position of the throttle is and how far depressed the gas pedal is. This is used to calculate a variety of things such as throttle percentage and engine load.
When the ECM detects a malfunction, the P2113 code is set. When this code is set, a Check Engine Light will be visible on the dashboard. In addition to the Check Engine Light, a failsafe mode will be set. This failsafe mode will remain until the code is resolved or normal operation is restored.
What causes the P2113 code?
Common causes of P2113 are:
- Open or short in the wiring harness
- Throttle control motor has failed
- Faulty throttle position sensor
- Poor electrical connection
- Pedal position sensor is faulty
What are the symptoms of the P2113 code?
With all cars the Check Engine Light will be seen on the dashboard. Symptoms may be felt before the Check Engine Light is set. The vehicle may have a severe lack of power, not start at all, have a misfire condition, stall, or not respond when the gas pedal is pressed.
How does a mechanic diagnose the P2113 code?
Qualified technicians should have little trouble diagnosing the P2113 trouble code with these steps:
Using a scan tool, check for any codes stored in the ECM including pending or history codes
Check the freeze frame data for each code present to see under what conditions the vehicle was under when the code was set
Clear all codes
Take the vehicle on a test drive attempting to duplicate the conditions the code was set under
Re-check for any codes stored in the ECM, if P2113 is found proceed further to the following steps
Perform a visual inspection looking for any damaged components or wiring that is visible.
Using the scan tool and its datastream, watch the sensor “B” while the throttle and gas pedal are operated
Then a multimeter will be used to check that voltage is present at the sensor
Common mistakes when diagnosing the P2113 code
Mistakes can easily be made when diagnosing the P2113 code if all steps are not followed in the proper order or if certain steps are not completed at all. Diagnosis on modern cars with advanced electrical systems can lead down multiple paths if care is not taken.
How serious is the P2113 code?
The P2113 has rather serious symptoms that can be seen with some vehicles. If the vehicle has stalling problems, the throttle does not operate, or the car exhibits other extreme drivability problems, then the car should not be driven at all until the problem is repaired.
What repairs can fix the P2113 code?
The most likely repairs for the P2113 code are:
- Throttle control motor replaced
- Poor electrical connection resolved
- Throttle position sensor replaced
- Pedal position sensor replaced
- Wiring harness repaired or replaced
Additional comments for consideration regarding the P2113 code
Speciality tools are needed to diagnose the P2113 code. One tool is a professional level scan tool. These scan tools do much more than just view and clear codes. The tools give technicians access to the live engine data stream which shows sensor operation as it happens and can be used monitor changes over time.
