P2163 - OBD Trouble Code

<<See All OBD Codes

Error code P2163 flashing? Don’t know what to do? Don’t worry, Parts Avatar is here for you! Here’ how you can solve the error code P2163. This generic OBD-II code decreased engine performance in simple terms is also known as a throttle/pedal position sensor "A" maximum stop performance. It should be noted that the pedal position sensor/switch is a segment of the accelerator pedal assembly while the throttle position sensor/switch can be found in the throttle body of the intake manifold. The speed desired by the driver is informed to the engine control module (ECM) by these sensors. Also, these sensors guide about how fast it should speed up to achieve the required speed. The code P2163 is set when the PCM identifies a defect within this sensor or the circuit for the sensor. At times, you might observe that the PCM may also restrict the speed of the vehicle to 20 miles per hour or less ("Limp home mode") to prevent the engine and the driver. All this is done due to the control module’ inability to precisely notify the engine performance being requested.

A malfunction indicator lamp (MIL) illuminates and the code P2163 is stored when the PCM identifies a maximum stop/wide open throttle position sensor voltage signal (from the sensor designated A) that fails to match the programmed parameter. The PCM enters the limp mode whenever the code is stored. Also, the engine acceleration can be observed to be limited (if not totally disabled) in this mode.

What causes this problem with the Throttle/Pedal Position Sensor A Maximum Stop Performance?

• A damaged TPS or PPS
• Loose or corroded circuits between the TPS, PPS, and the PCM
• Burnt or open electrical connectors
• A malfunctioning DBW actuator motor

9. Pedal Position Switch - The pedal position switch regulates the smooth idling of the engine in addition to acceleration and performance. So a faulty one is likely to disturb the whole functioning. We advise you to get yours changed or repaired now.
10. Electrical Connectors - Open or shorted electrical connectors? Don’t know how they can harm the system? Damaged electrical connectors also at times becomes the reason behind the corrosion in the battery. Contact Parts Avatar, your one stop stop destination for new set electrical connectors.
11. Dbw Actuator Motor - Throttle hesitation, poor fuel economy and and a disbalance in the air fuel ratio is likely to be experienced if the DBW actuator motor is defective. Repair or replace your now.
12. Automatic Transmission Parts - Having problems with the automatic transmission parts? It should be noted that automatic transmission parts are a critical system in the vehicle and needs proper care and attention by you to ensure long lasting operation. Repair or replace now if you want to prevent an erroneous system.
13. Fuel Shutoff Valve - One of the common problems caused because of a bad or failing fuel shutoff valve is sudden stalling in the engine. Another problem included is, when the switch trips for no apparent reason, even under normal driving circumstances, this is also related to the issue when the switch is faulty and produces a no start condition.
14. Digital Voltmeter - A distorted digital voltmeter can end up being the chief host inviting the error code P2163. So replacing one can be one of the wisest decisions to avoid a problematic system.
15. Ohmmeter - Observing dim or flickering gauges? A faulty ohmmeter can cause numerous problems including inaccurate voltage readings and inoperable instrument cluster. But not to worry! With help from PartsAvatar you can fix these issues in no time!
16. Throttle Actuator Motor - A damaged throttle actuator motor can cause electrical connection problems that further lead to an inaccurate or intermittent information to be relayed to the car’s computer. Restore or mend your throttle actuator sensor in order to get rid of these complications caused by the error code P2163.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD code P2163 here:

Common Symptoms

• No throttle response
• Zero or limited acceleration
• Engine stalls (when allowed to idle)
• Reluctance on accelerating
• A failed cruise control

Here are some ways with the help of which you will be able to correct the OBD code P2163:

• Repair or replace a damaged TPS or PPS
• Measures should be taken to fix a malfunctioning DBW actuator motor
• All the electrical connectors that are corroded or open should be mended or restored
• All the shorted or loose circuits between the TPS, PPS, and the PCM should be repaired or replaced as per the requirements

Here are some steps which you should follow in order to diagnose this fault code:

• First and foremost, the vehicle information source should be checked for technical service bulletins (TSB) that match the make, model, and engine size of the vehicle. Also, it is important that the symptoms and codes stored must also parallel. If you successfully end up finding a matching TSB, it will help you greatly while diagnosing.
• A visual inspection of all system related wiring and connectors should be performed. You should also inspect the throttle plate for any traces of carbon buildup or damage. According to manufacturer’s recommendations, the carbon from the throttle body should be cleaned. Repair or replace all the faulty wirings or components if needed, and then retest the DBW system.
• A diagnostic scanner, a digital volt/ohmmeter (DVOM), and a reliable vehicle information source will be required to accurately diagnose this code.
• The scanner should be connected to the vehicle diagnostic port to restore all stored trouble codes.
• It is advised to record all the information as it helps to extremely helpful while diagnosing the error code. Any related freeze frame data should be preserved too. These notes may prove to be quite helpful if the P2163 code is intermittent. Next, the codes should be cleared and the vehicle should be test driven to see if the code is reset.
• All the voltage spikes and inconsistencies between the TPS, PPS, and the PCM should be checked and verified using the scanner data stream, if the code resets.
• It is advised to narrow the data stream to show only relevant data for a faster response and easier diagnosis. Also, in case no spikes and/or inconsistencies are found, the DVOM should be employed to restore all the live data at each of the sensor signal wires. Next, connect the positive test lead to the appropriate signal wire and the ground test lead to the ground circuit to retrieve live data with the DVOM. Then watch the DVOM display while operating the DBW.
• Now search for spikes in voltage as the throttle activates slowly from the closed position to wide open throttle. It should be noted that the voltage generally ranges from .5-volts at closed throttle to 4.5-volts at wide open throttle. Also, it is advised to refer the vehicle information source for exact specifications. Suspect that the sensor being tested is damaged, if spikes or other inconsistencies are detected. An oscilloscope is also very helpful for testing the sensor operation.
• If the sensor is functioning as per the specifications, disconnect any linked controllers and test individual circuits using the DVOM. Also, the system wiring diagrams and connector pinout charts can aid to establish which circuits to test with their locations on the vehicle. The system circuits should be repaired or replaced as required.
• A malfunctioning PCM or a PCM programming error should be suspected only if all system sensors and circuits are functioning in order.
• At times, a number of manufacturers require that the throttle body, throttle actuator motor, and all throttle position sensors should be restored as a single unit.
